So Here’s the background for the issue.
I installed Nobara 36 (a modified Fedora 36 GNOME edition) and it was working fine on the external HDD until someone disconnected it whilst the computer was shut off and now i cannot find my Fedora installed drive in the boot menu. Also When it was working there were two drives to boot into in the boot menu
Why the two though i didn’t install two of them but just giving information of how the install was done from here on out.
First I Format 1.4 TB of space off of my External HDD that contained Ubuntu 22. Then Extended My NTFS Disk on that ext drive from 388 GB to 1 TB ( I use that as a backup for windows files )
Then the rest of 800 GB on that drive was unallocated and i extracted the iso file onto a 16 GB USB and just booted into that USB drive. After Start I selected install to Drive and then when selecting the location I chose the External hard Drive and used the custom partition so that it wont just format the entire drive. made a 1 GiB EFI Partition (\boot\efi), a 16 GiB Swap partition (I heard it was a good practice to get the same amount as your Actual RAM which is 16 GB DDR4), The Root partition with 100 GiB () and The Home partition with 600 GiB (\home) .
The install went perfectly no issues other than WiFi not being recognized which wasn’t an issue with Ubuntu but that’s fine I connected Ethernet and Just did the usual software installs.
I also Restarted the machine a multiple times and jumped from the internal drive to the external drive in the boot menu and all was going well and no errors occurred. other than the fact i Had two options in my boot menu:
Windows Boot Manager
Data Storage Device
I always chose Nobara though thinking it may mess up.
Well while it was installing a steam game, it was 3 AM so I went to bed. Later that day I come to the Computer and find out that the ext HDD was disconnected and the computer was shut off so? I connect it to the back and get into the boot menu but… What? Where are the two options? Nobara or Fedora? both were missing. So i though maybe just maybe my ext hard drive failed via a force shut down of the computer or someone pulled the external HDD out while Fedora was Active.
I boot into Windows boot manager and Search ‘Disk Management’ and lo and behold The disk was fine! also the NTFS Partition was working fine too. So what happened then? Also I installed the official drivers for the external HDD by WD and still no change.
here’s what Disk management showed
Here are my specs.
Motherboard : ASRock B450 Steel Legend

I am also just a Highschool Student who doesn’t understand most of linux and just had recently switched as i relaised that linux’s Visual Studio performs 7x better than the Windows counterpart. So please regard me as a Newbie to GRUB, EFI/UEFI, Kernel and other technicalities. and yeah WIndows 10 Pro 64 bit
