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.

    1. To boot endeavour, did you have to change any BIOS settings? If so, change those back and ignore the reat of this.

    2. Backup your windows user folder if you haven’t already, put it somewhere safely away from your PC

    3. No seriously, back up your files to another drive asap

    4. You will deeply regret it if you do not back up

    5. Do you know what the word hubris means? Back those files up, champ

    6. I mean, it’s your computer, so you can make whatever terrible decisions you want. You should still back it up tho

    7. Make a windows installation USB or, better yet, a winpe usb if you have access to another windows computer. Boot into it, but DO NOT continue with the installation. Instead, select the option that lets you run Startup Repair.

    8. Run startup repair

    9. When that fails, because it’s apparently a script that just freezes the PC for a minute before telling you it failed, follow this guide

    10. If all that fails: unless you really wanna RTFM on the windows bootloader and EFI partition, or piece together the equivalent knowledge from 83 different forums and blog posts after you separate out the mountains ofmisinformation, you can always just reinstall windows and restore from the backups… you did back up, right?
