Does os-prober work while arch-chrooted during normal EFI install?

Hi all,

Yes, that is the question:

Does os-prober work while arch-chrooted during the normal EFI install procedure?

Or more accurately:

Can os-prober find an existing Windows 10 installation while arch-chrooted during the normal Arch EFI install procedure?

My experience so far from repeated test installs is that it can't. When executed, it doesn't complain in any way, but it just can't. However, it does work properly when executed later on (once the install is all done with and one is generally fiddling with the system (which is a technical explanation of 'my process')).

I am trying to find out why this is.

Thanks,

Loady

My experience is somehow limited, but i remember i had to reboot twice before being able to choose OS, first reboot it took me straight to Arch Linux, second, i got os menu. I think os-prober is developed by debian devs, but not sure. It origins from debian though.

os-prober is quite unreliable, you are better off just adding the entry for windows 10 yourself.

If you are using grub.   Run grub-mkconfig.... inside of your arch install.
