Windows 10 won't boot after moving EFI partition

Question

On dualboot, I had two EFI partitions on two drives. One drive with EFI partition for GNU/Linux, second drive and EFI partition for Windows.

I moved Windows boot files from second EFI partition to first one.

Then, I deleted the second EFI partition. Windows starts booting, and ends up in BSOD.

Error: IO1 INITIALIZATION FAILED

I tried to "recover boot" from Windows installation media but it does not make it boot correctly.

What else can I do besides reinstalling?

Thanks

Answer 1

I created the EFI partition on the same drive it was before and moved the Windows EFI files there, it boots again.

I will stick to multiple EFI partitions and chainloading.
