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.
Dual-booting is fine, but this kind of thing does happen.
Either “os-prober” isn’t installed or /etc/default/grub has GRUB_DISABLE_OS_PROBER=false.
Fix those, then reinstall the bootloader.
