    NTFS is the format - Both MBR and GPT partitions use that format

    GPT is a partition structure, just a different one then MBR

    So to answer your question, yes you would have re-partition and format your current drive to support GPT partitions and Secureboot

    So, I can do this without formatting my drive then?

    Nope you have to wipe the disk and convert to GPT

    But if you make a backup image of the C partition (not the current disk) you can restore it to C latter without effecting the disk partitions or layout

    Will there be any conflicts due to restoring my drive from the old image (MBR partition) to my GPT partitioned drive? (e.g. difficult/impossible to boot afterwards, some/all programs not working, etc.)

    edit: I mean restoring just the c: partition, not the entire disk.

    you are not restoring the whole drive - you are just restoring the windows partition

    kyhi, I see our first respective posts in here were at the same time. Anyway, OP can use any number of free or fee partition backup/restore programs; as you said earlier, if he only image-backs the C-partition, he can restore OS onto the GPT'd C-drive later. I'm wondering if he also made a Ddrive partition for all his created and downloaded data, audio, visual, pics, etc. If so, that partition can be left alone, correct? He better image-back that Ddrive also, just in case the OS decides to format the whole disk.

    The only partitions on my boot drive are the ones windows made when it installed (i.e. it only has one drive letter).

    Are there any other features that require GPT? this seems like a lot of work just for secure boot.

I recently installed Linux onto a second drive, but I can't get it to boot by the other hard drive. It's a legacy hard drive, when I try to change the boot order it still keeps the UEFI on top and there's no way to move it down.
and if so, will it perform slower? Or only boot time will be affected? Any other disadvantage of doing so? Thanks
