hahaha! watching on full screen then went blank screen i thought my laptop failed.
😂😂😂
"master. I have failed. Please forgive me, master"
XD
Lol
I like that you pronounce it "f-stab" like I always do in my mind. I have no idea how long it was until I realized it was "f.s.-tab" for "file system table".
Hahaha, this is good info. I haven't thought to call it F.S. tab but you are right!
@@ChrisTitusTech yeah, i used to call it f-stab too... then i realised mtab also existed (mount tab) ... so realised it was fs-tab.... though just put some lettuce around and caesar would definitely call it f-stab... coz... caesar salad....
Don't ever take a test to see if you possess the traits of a serial killer, guys - your mindset on fstab speaks volumes :)))) jk!
It should be noted with chroot that if you're doing upgrade fixes and stuff you may need access to devices, in this case you will need to bind mount (mount --bind) /proc and /dev into the chroot environment first, failure to do so may come up with errors)
I learned this back in the day when I used Gentoo. You have to bind /dev and /proc to do the gentoo chroot for install. Best to always do it.
12:06 This is why some people say that dd stands for "disk destroyer".
By the way, you can add the option status=progress to see a progress indicator.
Then again, as long as you are careful with that one letter it will be fine. :)
To paraphrase the Genie from the 1991 movie "Bernard and the Genie":
Type the command "dd" with the caution you would normally reserve for "Please, castrate me".
I used dd to create bootable pendrive.
I typed correct device name of drive.
But it wont boot up. So I boot my linux and try to install gnome disk utility, and it asked passwd. After which problem began-My psswrd revoked. I had to reset in gnu grub but it forced me in emergncy mode. I checked and it said unknown filesystem vfat for /boot/efi.
Help
Also diskgenieus= disk destroyer
For Debian-based, just use *boot-repair* if the issue is a GRUB issue (via a Live Session).
Had this problem yesterday and boot-repair helped ))
I also go into advance options on grub menu and choose repair packages. Usually works great. Having a copy of boot repair is a necessity!
I didn't find boot-repair in the Ubuntu main depo. Apparently it's a ppa?
Why hasn't it been merged into debian main? Looks like a really useful tool to have there?
Edit: found this: www.howtogeek.com/114884/how-to-repair-grub2-when-ubuntu-wont-boot/
@@gnarlin4964 sourceforge.net/p/boot-repair/home/Home/ Looks like it handles a lot more then just Ubuntu though, and there are newer article out that actually mention 18.04 as well.
use boot-repair and save you 19 mn from this nonsense :D kidding
one time Xorg got deleted and I could not figure out why lightdm wouldn't work
This is a great lesson. I've screwed up installations and then apparently made them even worse using automated tools. It's always better to understand what's happening under the covers so you recover intelligently. Thanks!
EDIT: BTW I've started using Manjaro/XFCE and absolutely love how well it performs on all my machines.
Always i try to know what i did where did i messed up and how that thing Work before i start to find a solution
exactly yesterday I would have needed the recovery tricks as my filesystem had some errors that fsck didn't fix itself. :D
I already figured it out but this video would have saved me around 2 hours.
thanks for the vid, know more ways to fix it now!
Very nice. Few weeks ago I deleted my boot partition by accident, had to remember manual commands for partition creation, format, etc. I suggest a presentation for a disaster recovery when you disk has to be replaced and you need your OS back. What are the best tools, procedures, etc. for this kind of situation?
WOW I have a lot to learn. Thanks for the great lesson Chris
Another trick that often saved my ass, especially on systems that does not have a CD/DVD drive or when you don't have a USB pendrive with you, is to boot directly into an ISO image file.
Suppose that you have an bootable Live ISO image of the distro of your choice in your /home/user/Downloads/ folder or suppose that you have the foresight to put a Live ISO on your /boot/ folder. You can use Grub Shell to loopback mount the ISO image and boot directly into that disk image; this has the exact same effect as booting from USB drive without needing any extra hardware (or access to the USB port, if that matters). From the Live system, you can edit files on the installed system or chroot into the installed system, and if you used Live ISOs that boots into a graphical environment for installer, you would be able to do your fixing from a GUI environment (which has the benefit of having a working networking and a web browser).
Thanks for share that knowledge! I must learn about that.
Thank you man I was just fucked up with my Display Manager and Now I Saved My System Booting in bash just Worked out For Me
11:37 "dd" stands for "data duplicator".
At 11:58 you can see why its alternative (and way more popular) name is "disk destroyer".
"dd" also stands for disk destroyer! Why would anyone want to use a very low level tool that can easily damage the data on an entire disk? There are ready made utilities for boot failure: I strongly suggest users to use those first.
Boot failure can be mitigated by using a dedicated partition for a tiny OS hosting the bootloader. This way, no installation can ever modify the bootloader and booting is thus guaranteed for all installed operating systems. To achieve this instead of kernel file names I use the "/vmlinuz" symlink in grub.cfg.
Note and Warning: Using a separate operating system for the bootloader requires manual editing of grub.cfg which can result in boot failure if not done properly. Manual editing avoids having to use user scripts to custom configure grub but it has its downside especially for people not familiar with programming languages.
I did mention the "disk destroyer".
And wouldn't you agree that using dd to create a bootable recovery medium is still way simpler and less error-prone (with necessary precautions, of course) than the procedure you suggested?
CentOS' page recommends dd. i think I used it to put Anaconda on my flash drive and no amount of formatting in any tool will remove Anaconda now.
Most awaited video
Saw you had defaults,noatime,discard for one of the SSD entries. The recommendation is to not use atime, instead, just replace with
... defaults,relatime # use of discard will shorten the life of your ssd by a lot (say 50%)
Thank you Chris for this beautiful explanation of chroot. I asked you on Twitch about this. Greetings, Patrick. AKA SquadraMunter
Yup, You were the reason I added it to this video ;)
@@ChrisTitusTech Thanks Chris ;-) I still got one question regarding the unmount process. I saw you did a unmount but it says target is still busy. Does this not affect file corruption? Since there is still write or read in progress? I hope you can answer this.
Hey... how about a video on how to upgrade to a larger hard disk on an arch linux pc (without reinstalling)?
Great tutorial! If i may leave one suggestion at 14:08 if there's lost of info as part of some terminal output, if you mean to single out some piece of information could you maybe please show some highlighting rectangles or arrows in editing? Sure advanced users would know where to look or what you mean but this is meant for newbies right? Thanks.
This comes at an opportune time. I tried to install Linux on my Windows 10 laptop with manual partitioning and it did not go well
I realize this is an OLD video-- but I just found it and NEED IT.. THANKS
Same
This is the best video of linux repair I've ever seen. I wish I knew this before. tks!
Thank you for teaching me how to access the shell from grub! My problem was the nvidia drivers. I purged all nvidia content from my install and got back in 👌
Installing 32bit debian on Hyper-V is quite a headache, thankfully this video helps me
thanks chris, i changed my video driver and got the black screen, to get it back l launched linux from a usb stick and got to timeshift from that, this way seems easier
Always sync after dd. On some hardware the usb-drivers work crappy with usb-sticks and the writing process might not be finished even though dd drops you back to the shell.
I have this kind of issue a lot with Asus and Manjaro. Not with Arch though.
Great video Chris, you got a new subscriber! Keep it up man!
Thanks .. this was a real cool video. I had to do mount from CD to fix sudoers file. Another time, our VM crashed b/c it ran out of disk space. It wouldn't boot b/c of no disk space left. So, we booted of live CD and cleared space in /var/log and added more space to that logical volume.
Thank You!!! Was about to reinstall my OS but chroot fixed my problem!
Well done.. thanks...I know it's f. s. tab, but no matter how hard I try I can't stop calling it f stab...
Tried several things but it didn't boot from pendrive
Well, I'm in emergency mode but honestly now does any of this help to solve that problem - unless I screwed around with a line and then came back and erased it?
Very useful guide, the best which can find!
Re @ 6 min, just using 'single' in the vmlinuz line will drop you into single user mode, makes things easier :).
Using the 'single' keyword still starts your init process (systemd, for example) and try to start the system. If your fstab is that badly broken (or a fubar shell), then you have to use init=/bin/bash to bypass ALL normal system startup processes.
@@robgibson8600 true, it entirely depends on the circumstances for which you're entering a low level mode to make adjustments.
Thank you Chris for this video. Thought I bricked my computer yesterday when I attempted to move the mount point of my Steam Games drive to the etc/fstab directory. Thankfully your first option fixed the problem for me by taking it the offending programming line.
I now just wish that Steam would go back to allowing games to be saved to a separate drive. /media and /mnt do not show as a save option in the most recent iteration of Steam!!
Many thanks Chris, I'm completely new with Linux, my recent Cinnamon installation crashed this morning and after a few trials with your first instructions how to use Timeshift recovery, my original screen asking pw loaded. Amazing teaching. Do you have some online training courses for newbies like me??? Much appreciated, rgds
OMG! I've been trying to solve this issue for weeks now, and finally stumble into your video IT WORKED!! Thank you very much.
I've installed W11 to my lap, because I needed to use proprietary software (only available in windows) did dual boot but my GrubHub disappeared and could boot back into Linux! But this fixed it thanks again!
Great video, you made fixing Linux look easier than fixing a botched Windows Update! XD
I have also found it useful to have Gparted on hand on a USB key/CD as well. It's lightweight, and has a basic GUI that's functional enough to open multiple terminal windows up for those cases where you need to look at things side by side on the system like live files vs backup files and Gparted itself is great for resizing/moving partitions around. Knoppix can also be pretty useful, albeit overkill and a bit top heavy, but you can transfer files off the broken system with it in a GUI if that's what you prefer.
Chris thanks for what you do as well your saving my Arco bacon thank you sir!!!😊
This was awesome Chris. Thanks so much. I had upgraded my SSD by cloning into a larger one and afterwards, the Ubuntu won’t boot. Turns out the fstab was also copied over from the original SSD and needed to be corrected to have the right UUIDs. Doing it the way you suggested (pressing e from advanced options and launching the bare minimum shell to edit fstab) didn’t work for me as the filesystem was mounted as read only. Fortunately, in advanced options, there was also an option to launch the shell using upstart and that let me edit and save the fstab with the right UUIDs and the system booted just fine after a “hard” shutdown.
I have similar issue here going on one month now. I am not able to edit fstab as it is read only, could you kindly assist me? Is there any means via which i could reach you? Is upstart an app ? Any help is higly appreciated. Thank you.
The nano/etc/fstab is shown unwritable. Any solutions?
in other distros you can boot into the repair boot option and get to command line and try fsck -n -f and reboot
Ctrl + Alt + F2 and a sudo update && upgrade did the trick. Guess my Nvidia drivers were the culprit
*Just press and HOLD F8 while restarting or booting, and then choose advance options. Next just select an earlier version from the list. It will boot up to the prior version and from there, you can trouble shoot. and ultimately delete the newer version from the command console.*
Thank you, Chris. Very useful.
Thank you, this is awesome. Went through something like this just last week after an update. Timeshift saved me!
@0:23 What if your system just boots into an intramfs screen and nothing happens except a blinking cursor?
@0:27 The only silly thing I did long time ago was using discover to install the newest updates. :)
I have heard tell of being able to boot from a local iso file on your hard drive
Challenge Accepted! Time to make a video about Recovery partitions and making them.
Yes, I can confirm, that is possible. I've done it with a Linux Mint iso file in my /boot folder, via grub-customizer, and was selectable from the grub menu. I still found it was a bit hit or miss though, and either worked or didn't, but when it worked, it worked flawlessly.
@@ChrisTitusTech Now you're talking. I might have to nag the daylights out of you about this, so that you don't forget ....in the nicest possible way though. :)
i mistakely delete partition . not starting what i have to do?
Thank you, thank you, thank you!!!! This was a life saver since I'm a newbie and made a major mistake.
After fresh install on my BackBox Linux system GRUB was out of resolution range so i entered safe mode using the ESC button, i chose to repair the GRUB and voila. Easy and fast boot recovery
This just saved my life. THANK YOU
Absolutely love your video's but is there any way for you to make the font larger? I can't see what your doing and i like to read the screen.
amazing,,I've ran into many of these situations ,,this is great.. thanks man,, everything pretty much in one video AWESOME. Thanks
MR.CHRIS TITUS REPLY TO ME YOU ARE THE ONLY MAN CAN ABLE TO ANSWER FOR THIS QUESTION.
I HAVE SOFTWARE ERROR IN MY LAPTOP SO THAT I CHANGED THE OS FROM XP TO LUBUNTU OS. AFTER THE INSTALLATION COMPLETED FOR LUBUNTU. IT STARTED TO BOOT. BUT IT IS WITH A PARALLEL BLINKING CURSOR. WHAT IS THE SOLUTION FOR THIS PROBLEM. SAY THE SOLUTION TO ME
Video cuts out 2:11
At first I thought it's an artistic choice to represent boot failure.
@@Noxeus1996 it's a total mind blank :P
Bah damn kdenlive messed up it looks like. I went ahead and did this via youtube live editor, this should correct in the next 24 hours.
@@ChrisTitusTech cool. It was such a coincidence that you had the boot failure at the same time so I thought I was on purposes haha.
Nice logo, is that new. I am planning on moving on from MATE desktop and you gave me an idea to use change root to install an arch system on a different partition for easy migration. Now that you have done a system recovery video, how about a data recovery episode
Fantastic tips, thank you very much :)
I just upgraded to kali linux 2024.1 and my battery died and had broken upgrade. On boot nothing but black screen ran debian boot-repair from live usb nothing got fix i will try this two methods 😊 thank you
will try this, things just stopped working from one day to the other even tho I did not try anything weird.
Hi Chis I got an mce problem what could it mean thanks in advance I hope you or your community can help, thanks a lot
Damn you need a KVM switch Chris!
I know ;)
Great. Thanx a lot solved my issue with boot.Thanx again.
Gracias tio, acabo de arreglarlo para clase. Me has salvado la vida ✌
you don't need autofocus ON for your way of filming
Thanks Netik, I will change this. Canon AF has been on a the blink lately.
I've tried to load the Ubuntu operating system on my laptop but when I reboot the computer tells me that there's no operating system. I tried it again with Mint and got the same thing. I then put Windows back on it and it works fine.
chris is a g all my homies love chris
sorry didn't go to the end of the video but how to restore the timeshift backup with the USB Key
Does using Linux Mint Boot Repair tool count?
hey chris sooo i have a fresh iSO of manjaro in my usb right, and i'm running a MSI board and from what i can tell MSI hates linux as it seems to not wanting to boot im getting a grub rescue mode as unknown file system or is the install borked?
Is it MBR or GPT?
Google that.
@@igorthelight the boot was borked i got in lol
Running an Nvidia GT 630 and installed Ubuntu, it was working fine, booted this morning as keep on getting stuck when booting up, shift didn't open Grub for me, I installed a new image, with the third party drivers but unfortunately it's not working! What could it be?
Keep in mind it's been working fine, until now!
Chris, that was interesting but lost me a bit. If you go into 'edit' it would be nice to know what the entries are for; why is set root 'hd0,1' shown on one line but on the vmlinuz line is it shown as root=/dev/sda1 - appreciate it is usually shown as root=UUID=
Also below the linux line it has initrd - I think it is initialise Ram Disk but what is it's purpose?
When are you going to revisit Bedrock Linux in VirtualBox? Its been a long time since you said you would.
Bedrock is the Devil! I think the only appropriate way to revisit it, is to buy a Ouija board and do it via live stream with the lights turned out.
@Donald Mickunas Hehe, Bedrock is an exception. It allows you to install arch, debian, fedora packages on one system... Yeah, It is an abomination.
Has anyone had an error screen initramfs in Ubuntu 20.04
Being an new I.D.10.T. user 2 Linux...
I was on low battery & was not paying attention;... proceeded to do a clear re-start... On switching back on the battery & Laptop died... Realizing my mistake;... I plugged the charger in & tried re-start but all I get now is a screen prompt initramfs... So I'm kinda stuck...
Really save my life. Thanks a lot ctt
When you booted into the bash shell, couldn't you have just used "exit" rather than a hard reset?
what if you cannot boot the disk?
I did an upgrade to Ubuntu 24, and wound up with "usr/lib/systemd/system-generators/netplan failed".and no bash prompt. Hoping this will help.
Why did they ever abandon lilo?
Literally as I watch the 1st 30 seconds Ubuntu boots 😂 I guess you scared it straight as soon as I started watching
Extremely valuable video.
another great how to vid, as usual!
I've watched about 8 plus, ur vids, and seems that you didn't want to enlarge the font in the terminal this time?
And since I have really poor eyesite, even with my browser set at 150 zoom I couldn't hardly see a word, or a code, or what ever that was on the terminal, even in zoom mode!
But you do have, most of the times, the best "fix it" after Windoose broke it vids here on utub!
My problem was, and is year old Asus, having a 2002 BIOS that was updated, but after GRUB was wiped out... NOW only boots EFI, and my live usb's decided to be legacy only, somewhere, some how, after Linux Winland Android mirroring app wiped out grub! NOW the only way I can boot to any of my to many usbs, is not the BIOS but W10, pick a stick
Computers are now more of a "hobby," and a pain in the pocket, than useable devices, when running dual booting!
LOL!
I have a question, I am going to take CS degree and currently i am using windows 10. Is it worth it to change to ubuntu for learning programming language or should I just stick with windows?. So far all my senior told me that windows 10 is good enough for learning programming but in the future they gonna learn ubuntu for c++
Win10 is good enough, except that you have to buy all the software and the tool chain set up is more awkward.
Roll up a Linux distro and all the development software is readily available for nothing, the stuff all works well together and you can load your system up with different languages and tools to try different things out - e.g. build a dynamic linked library in C or C++ and use it in Python.
You can if you wish either run a Linux distro using "Windows Subsystem for Linux" or just set up a Linux virtual machine in VirtualBox if your primary system is Win10. Then you have all the benefits of the Linux development environment and you don't have to throw all your eggs in the one basket by switching from Windows to Linux.
Do the VM thing and just see how good it is.
Dingo Kidneys Thank you for ur info
I have a problem on the boot screen, this line always shows up (initramfs...decoding failed) then black screens a bit before booting up to my lockscreen . I can use Mint 20 normally but this always bother me and makes booting up longer than usual.
What if I am not even getting grub screen? It is a Proxmox and it's acting like there is no bootloader at all and says can't boot from drive and goes to network boot.
How do you get it to boot from a flash drive so you can wipe it and start over if you're only options are GRUB or terminal and it bypasses the flash drive on boot?
Its easy restore from backup but I like systemback make a read only iso so it always works it can't get a virus or mess up it's a read only optical disk they boot slow but can copy os to ram so once booted it runs much faster than a hard drive it's ram speeds
Another question, where things seem to be completely different in Ubuntu. I am now on version 22.04. It’s 2024, and the file /etc/fstab is dated May 2017. Why is that never changed? I did several complete system upgrades since then.
Thank you!
Hi. I've been having some boot up problems with my ubuntu... And no one seems to have a clue what the problem is. Care to help out?
What is that large icon on the lower right side of your screen that is displaying all the CPU, time and memory information?
What if linux mint keeps booting in to windows repair? I can't even get in to linux to open a terminal, holding shift doesn't do anything.
OK, I booted to the usb, so now I cam get to a terminal but still don't know what the problem is or how to fix it.
Server crash and restart then how to figure out last thing happening before crash ?
I have a HP 14SS 14-cf2006na laptop and I enter the bios and when I select on boot options and then select USB flash drive/ USB hard disk it won't boot from the USB flash drive?
Awesome but unfortunately this didn't help me. My MX Linux 21 is stuck on command line and I can't get it to run the GUI. It asks for username and password and that's it. It's really frustrating, hope I get a solution soonest
Just wondering ... don't know why your video put this in mind ... haven't ever even considered this:
Would it be possible to chroot into a completely different type of distro? E.g. using that Arch ISO to then fix a Debian install? I'm wondering if something like apt would even be a program to run. Though I'd assume at least some stuff would fail, perhaps even spectacularly ;)
The init=/bin/bash on the kernel line looks cool but absolutely does not work on any newer system I have tried it on.
This video is four years old.
So this appears to be and old trick that no longer works.
(Debian 12 (bookworm) testing on stock up to date fresh install.
And by does not work I mean specifically "cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell"
At the local console.
Great stuff,but this isn't helping me at the moment. My desktop is stuck on the login screen and can't get past it. Mint 18.3 Sylvia. I tried timeshift restore 3 times and still no dice . Dont know what i did or how but it seems that the restore also filled my hardrive. Got like only 2 gigs left out of 120. I could get in as guest after multiple tries. But I can't do much in there.
I can't even access TTY in Kubuntu 23.04. Also getting the error "no suitable video mode found" when i try to boot.
Awesome job!
