Question Help needed.

[Pedwarpimp]

I'm new to PC building, and just built my first pc, with Windows 10 installed on a 520 NMVe SSD drive and everything seemed to be fine, however the drive was in legacy mode not UEFI, so I tried converting to this UEFI, everything seemed fine until I reboot the pc after changing the Bios mode to UEFI.

Now all I get is the enter reboot system disk message

but more concerning is my keyboard mouse or anything else is all unresponsive so I can't do anything.

Any help will be much appreciated.

Thanks

Carl.

You will need to reinstall windows again if you change from Legacy to UEFI .

delete all System partitions and allocate them again.
