Help! My Windows Partition Disappeared from Dual Boot Menu After Crash

You might want to try running `sudo os-prober` in your terminal. If that returns nothing, open the grub configuration file by using `sudoedit /etc/default/grub`. Make sure to uncomment or add `GRUB_DISABLE_OS_PROBER=false`. After that, don’t forget to update Grub again using `sudo update-grub`.

First off, check if your Windows partition is still accessible. If it is, you can try fixing it using Linux Mint's boot repair tool or simply run `sudo update-grub` in your terminal. If Windows Boot Manager isn’t automatically detected, you may need to select ‘Boot from file’ in the UEFI boot menu and point it to `/EFI/Microsoft/Boot/bootmgfw.efi` to manually boot into Windows. If that works but you still can't see it in Grub, you might need to set the boot entry by hand.
