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.

    I have a similar issue on my PC. My windows ssd doesnt even appear in the BIOS unless I keep my computer on for over 30 minutes.

    I know it’s not a fix but you could try booting to endavourOS for sometime and then reboot the system into bios and maybe the windows boot entry will show up. (This works in my case, although when I shutdown the system and boot it the next day, I have to repeat all this)

    Whenever I install a minimal linux distro like void, arch or gentoo all my boot entries disappear somehow (even though I have configured grub correctly). But for some reason when I install a distro with the calmares installer this doesn’t happen.

    I even tried reinstalling windows multiple times on different ssd’s still no luck. My hunch is that the NVRAM in my MSI motherboard is causing the problem.

    I would appreciate it, if anyone more knowledgeable on this topic can shed some light on this.
