os prober being stupid

[gray jasper]

i can't even remember what i did but (my battery did the big die first) then linux stopped working so i reinstalled and now windows won't show up in grub, tried os prober and got no results, please help

when i try os prober it pops up with no result, windows isn't dead as i can still access it in the file manager

alrigth.
are you running os-prober in the installer?
if yes, finish the install, boot into arch normally (not from usb), login, mount your EFI partition as /boot and run os-proberagain

if you are not on the installer, make sure to mount your EFI partiion on /boot, and try again

[ashen loom]

have you mounted while you ran

assuming youre on efi, make sure you mount windows boot manager

[ashen loom]

why specifically /boot

[vast zinc]

I usually use /boot, and i know it works with os-prober once you boot into arch

[ashen loom]

oh, i would just use /mnt because thats meant for mounting

[vast zinc]

well i think a few things would automatically install what they need onto /boot, and wouldn't recognize it on /mnt
mkinitcpio -p or pacman -S linux for example

[ashen loom]

i see

but also

for most, just one esp with kernel is impossible on windows/linux dual boot

windows 10 installer does not have enough space for it

so you would either not mount to /boot or you would have multiple esps

i digress

[atomic bison]

You can mount it anywhere

You don’t need to modify it or anything, os-prober just needs to know it exists

[vast zinc]

for this reason, it's best to create an ESP before the windows installer does, since it only makes 100MiB
in my experience, 512MiB has been enough for both Windows and Linux with kernel

ik

oh nvm
