    There is a lot easier method of doing this. I did a lot of research on this topic and I found this as the best and most easiest method.
    Pre requisites :- Windows 10 1803 or higher.
    There must be atmost 3 partitions In your disk. If you have more then backup all your data in the local disk with least data and delete that partition.
    Steps:-
    1. Search for advanced startup settings.
    2. Click on advanced restart option.
    3. Go to troubleshooting option.
    4. Select the command prompt option.
    5. Your device will restart with a command prompt open.
    Type - mbr2gpt/validate.
    6. Now type mbr2gpt/convert.
    7. Your OS will be successfully shifted converted to UEFI. Restart your PC and open BIOS settings by pressing F11 ,F12,F2 depending on your PC type. Go to boot menu . Change the boot mode to UEFI.
    8. Go to exit menu select exit saving changes.
    If you have done everything right your OS would be shifted to UEFI

  • @Ottonic6

    Kinda confused me for a minute. It said before you converted to GPT it said the operation will overwrite all partitions so I thought it would wipe the Data which didn't really make sense.. But when I installed W 10 it put my System Reserve partition on the other HDD which is already GPT, so that shouldn't matter. All I am going to do is convert the OS drive to GPT and BIOS from Legacy to UEFI, then shrink Windows 300MB, then create the EFI partition in the 300MB space I cleared, followed by building the BCD... Right?... I hope it works. Or maybe I will look and see if I can move my System Reserve partition to my Windows drive also... Thanks!... UPDATE>> I had read that if you have more than one partition you will have a system reserve. I only have one partition with everything on it so I took the other HDD out and the system booted right up. No startup repair, just quickly booted into windows. But if I do this I will be adding the EFI partition so I guess that means I will probably have to add the S.R. partition. Not sure. A little more research on that matter. Thanks!

My current Intel-DH67BL motherboard supports UEFI but it is currently in legacy BIOS mode because till date I was using 4x 2TB HDDs in my PC case. Now my existing of storage is filled, and I presently need 4x 4TB HDDs (yes, 16TB) for storing my 4K photographs. Do I need to do all these complicated and tedious DOS commands?
