hello, i would like to know how do i switch from legacy bios to uefi? when i first got the pc it was uefi and it worked fine until i turned it off by accident which corrupted the boot, so i got a new windows 10 install media that was bios instead of uefi, and it installed and stuff worked fine until pc started to freeze, got alot of BSODs, etc...

this never happened on uefi, so i want to switch back to uefi, how do i do it??

Hi:

 

You will have to reinstall W10.

 

When you go to install W10, there should be two lists of boot devices in the F9 boot options menu.

 

Select the EFI USB flash drive and not the legacy one and W10 will install in UEFI mode.
