Are you using UEFI, if so, the ESP of window smust be mounted when running os-probe.

Ah, I see, please give some more context when you speak, you know I don't have neural pathway abilities.

Is the sda1 the ESP?

fickle roost Aug 28, 2023, 1:06 PM

#

yeah

#

sda1 is efi for arch too

radiant tartan Aug 28, 2023, 1:07 PM

fickle roost sda1 is efi for arch too

So you share the ESP between Windows and Linux.

yeah

radiant tartan Aug 28, 2023, 1:08 PM

fickle roost yeah

If so, configure grub to use os-probe and add an entry to fstab to mount esp on boot.

Finally, execute

grub-mkconfig -o /boot/grub/grub.cfg

how to do it?

radiant tartan Aug 28, 2023, 1:14 PM

#

fickle roost how to do it?

All these solutions, as I mentioned above, and what you need to do next, can be found in the ArchWiki on grub and fstab. Would you mind reading them first? you might also find other things you have probably overlooked during setup.

#

Of course, I could just tell you what to do here, but that betrays a certain purpose of learning, which is to discover how to solve problems on your own.
Farewell.
