[SOLVED] accidentally deleted (EFI) partition - how recover?

Hello ,

on new comput er
have a triple boot system Windows 11 Enterprise - Ubuntu 24.04 - Devuan 5.0/6.0
all 3 system have a proper NVME ;

now had some issue with Win11 which prompted me to re-install Windows 11;
since those NVME are small and pesky, did not bother to remove them manually (at first) from motherboard.

encountered steps on the way, which baiscally prevented me from installing Windows 11 again on the same NVME;
could not properly figure out where the problem could lie; thought it would be because of using USB installer, but it was the same with DVD drive;

would not want to remove other NVME since that should not be necessary;

what seemed to help was to change setting in BIOS  > Secure Boot > from "CUSTOM" > "OTHER" - back to "WINDOES UEFI" >> afterwards instaling Windows 11 went through without no proplem; but could not longer boot the other OS, so i had to change back to "CUSTOM" > "OTHER" and it seems that Windows is happy algon the way nevertheless;

now my problem;
in the hustle, several time deleting and installing again Windows on the same NVME , i must have accidentally once clicked too fast and deleted a partition from another NVME , either Ubbuntu or Devuan - one;

now the Linux, sti.ll boot in OS, however, with Devuan there are several issue, which i hope to clear with your help;

basically .

1. it takes very long to boot (this problem is indipenddent of error i laid out above)
    there is delay on boot due to
   

like [0.805369] hub 10-0:1.0: config failed, hub doesnt have any ports (err - 19)

2. and boot after this delay stalls with following error:

   

fsck.fat 4.2 (2021-01-31)
fsck exited with status code 6 (File system check failed

so most probleably  i might have deleted the 1st partition on the NVME for Devuan;

please you be so kind to show how to recover from this error;

thank you.

Boot your Devuan installer and reinstall the boot manager from the Expert menu.

Re: [SOLVED] accidentally deleted (EFI) partition - how recover?

Each time you format a partition or drive, the partition gets a new UUID.
The old UUID's listed in grub may be different, takes longer to find, and check.
You may edit grub to boot, then fix the problem with update-grub on each OS.
I hope this helps next time.
