just enable os-prober in the grub config and mount the windows partition that contains the windows bootloader

and then run grub-mkconfig again

[SOLVED] Grub broke - Arch + Win10 dualboot set up

#

(Got a blank grub screen) might be slightly whacky boot order in the bios) but Linux loaded fine and I did for a smidge of another reboot see the windows option when it loaded up once before

native smelt
#

What's the problem

untold forge
#

i fixed it, it was a quick check of the boot order menu

#

nothing major
