I need help on EndevourOS, it's not recognizing the Windows boot and I don't understand how to solve it. - eviltoast

So, I made my bootable EndevourOS image. I installed it on my secondary SSD, while I have Win11 on my primary SSD (need it for my job).

When I installed it I booted it up and everything was ok. A bit confusing, but ok.

Wanted to get into Windows again because I needed to work on something for a design (Adobe programs), next thing I know: my computer isn’t recognizing my Windows drive…

It’s there. I can see it on the “disks” app on EndevourOS, I can mount the disk and even see my files in there. But it just won’t boot.

Read the documentation and it mentions an “os-prober”, that I needed to change GRUB_DISABLE_OS_PROBER=false in the etc/default/drub file… I don’t have that file anywhere in my system…

I installed os-prober, nothing. I searched any other folder with a similar name and checked files… The only file with a mention of os-prober is grub.d that says “if GRUB_DISABLE_OS_PROBER=xtrue then random warning”, but that is a set of instructions (i think), not the actual file.

I don’t think I should have tried EOS/Arch when I’ve been learning Linux for only 2 days, can anybody help me with this? Thank you for any answers in advance.

    hi, I think EOS uses systemd-boot as a default bootloader. so grub may not matter. I don’t have much experience with systemd-boot, but for now, you could just try and boot from the primary windows drive by pressing the BIOS key and changing the boot order (or using your motherboards‘ external drive boot button)this key is different for many motherboards, so you should check google for yours. As for systemd-boot, I don’t have much experience so I’d either google (specifying the two drives) or ask gpt. Good luck!

      After reading all these comments I just decided to format all my drives and start over. I made the mistake of installing EndevourOS at 12am when the next day I had to use Windows for my job! I did enter BIOS and changed the order but not even my BIOS recognized the OS, it just said “checking media… fail” and it fell into a permanent loop. What I said in another comment was that I thought this had happened:

      It’s weird, but I had Fedora installed on my secondary SSD. Apparently when I did a clean Windows install, it installed in the primary SSD but took a part of Fedora on the secondary SSD as a Windows EFI partition. Then, when I installed EOS I selected “erase the disk” for the secondary SSD. I think it erased that EFI partition and I couldn’t go back to windows, but since the primary SSD still had my files I could still see them. To be honest, something like that never happened before so I’m not even sure of what I’m saying.

      I’m not even sure if that’s what happened, as I’m still not an expert in these things, but when I erased the secondary SSD there was a “EFI partition” I had not seen before.
