Windows not found by os-prober posted on 04 July 2023

I recently bought a new computer (a Lenovo IdeaCentre G5 in case someone is curious). When installing archlinux (in dual boot), I couldn’t get os-prober to detect Windows even though I could see all the Windows file in /boot/EFI/....

I eventually just manually added a grub entry

menuentry 'Window' {
	search.fs_uuid <UUID>
	chainloader /EFI/Microsoft/Boot/bootmgfw.efi

Where you can get the UUID of your /boot partition with blkid. Interesting enough if you put the wrong uuid, grub will complain but will still boot Windows.
