Hello

i delete the uefi partition from my drive! So i cant boot to my system!

However, i make a new install on other disk! And the new disk has an uefi partition!

From that partition i make to boot my old system! Paradox!

But if i delete the new drive my old system cant boot again!

How can i make a new uefi partition on my main system without clean install???

Copy the EFI folder on the EFI partition of the new system disk to the desktop, now mount the EFI partition of your old system disk, find and delete the EFI folder that is currently on the old system disk and replace it with the one you copied from the new system disk.
