Yesterday I installed windows 10 from a bootable USB (which contains a folder named efi so I think this bootable USB support both boot modes). But later I learned that UEFI mode is better than legacy (BIOS) mode. So I first confirmed which boot mode I am in by typing msinfo32 in run dialog and it display legacy.



I also checked my hard disk partition style, its MBR. I know I would need to convert to GPT partition style before I install windows 10 in UEFI mode.



But I don't want to use third party softwares and I also don't want to update to windows creator update probably because windows update takes lot of time and data also all of the third party softwares are paid. So I tried doing it with diskpart utility by booting from bootable USB and opened up cmd in the repair windows and typed these commands:



X:Sources> diskpart

X:Sources> list disk

X:Sources> select disk 0 (as my hdd was disk 0)

X:Sources> convert gpt


But it says error disk is not convertible.



So how would I reinstall windows in UEFI mode ? Any help would highly appreciated.
