Some time ago I installed a larger Windows update, I guess also using an external flash medium to have enough space. Since it took some time, I left it running over the night. I think the next morning it had booted into a recovery mode where the default options all did not work. So I did some search on the internet and tried some stuff on the command line. Unfortunately that made things worse and the PC did not boot Windows at all afterwards (not even the recovery mode). All I got was the EFI shell.
I then went ahead and booted from a recovery medium. Apparently the System (EFI) partition is completely empty (I might have formatted it trying things, don't remember). Also the steps I could find on the internet to restore it did not work.
I guess the problem is that the
C:\Windows\boot folder is incomplete. Running
bcdboot C:\Windows /v (
/v for verbose output) I get some error messages for example that
C:\Windows\boot\EFI\bootmgfw.efi do not exist.
Is there an easy way to repair the folder or the System partition (maybe from the install media)?
