boot-repair

I'm really grateful, it's saved me many times, but often I'll forget about it from the shock and joy of surviving it (because it's already in my system), so I wanted to express my gratitude today.

The tools gives me detailed and accurate information about all OS and partions. It lets me publish the data to a pastebin. But ultimately fails to actually repair the system boot with this message: "Please enable a repository containing the [grub-efi] packages in the software sources do Debian GNU/Linux 12 (bookworm)(/dev/sdb2). Then try again." I could not find such a package but it turns out that grub-efi is already installed on my system as part of another package. Posting about this error in the Debian installation forum yielded no usable result. A google search shows that others encountered the same error -- none of them got a resolution that would allow the boot-repair utility to succeed.

Fabulous : how many did this tool help me recovering the disk architecture :-)

I had to rebuild a RAID array due to poor original design of array. I broke the boot because the UUID of a new drive was different. Yeah, I could manually fix it, but I knew it would take a while to lumber through the process, having never done it before. I booted the USB stick and five minutes later was up and running! It only gets four because I could give it 4-1/2 :).

This is possibly my absolute favourite tool ever written. Thank you so much, I have no words -- perhaps due to sleep deprivation. I love this tool.
