Title. I dual-boot Windows and Linux. I always saw people making “WINDOWS DELETED MY LINUX BOOTLOADER OMGOMG” posts and it had never happened to me. Now, the opposite has happened. I switched from EndeavourOS to OpenSUSE and now my windows install is no longer selectable on boot.

I keep Windows in a separate drive entirely, so instead of using grub, I use the EFI’s boot-select menu thingamafuck (look I don’t know jargon okay?) to choose Windows when I need it.

Well today it’s not there. Only the Linux entries show up. The Windows partition itself seems to be in good order, like, I can access it from within Linux no problem.

But yeah it doesn’t show up on my EFI selector thingie. I imagine I could get the EFI Shell going, but I have no idea how to use THAT either.

    I FIXED IT

    Fucking hell that was a pain. And as most of the painful things in life, it was mostly self-inflicted.

    I consider it the polite thing to make a report on what I did to fix things when I solve my problem in a tech support thread (in case someone is ever searching this, to avoid the xkcd scenario ) so I will do that now:

    • First off, going into a Windows install media and running some commands, as described by @[email protected] and @[email protected] did do the trick for reviving Windows.
    • BUT, I am an idiot and I pointed Windows to the wrong thing, so it wiped out my Linux boot partition. O o p s i e . . .
    • I was a bit stumped on what to do, and had actually flashed the USB drive (this idiot here only owns ONE USB drive) with the SUSE install media, fully intending to do a complete reinstall, but THEN,
    • I realised that in the install media’s menu, there is a “boot Linux system” menu, and entered it on a whim
    • Sure enough, that found my existing OpenSUSE install and let me get into it.
    • From there I just used YaST to re-install and re-configure grub
    • Both Windows and Linux seem to be functioning now, yay

    So, 85% “me being an idiot”, but, the problem is solved. I thank everyone who made a comment.
