GRUB2 can't find root device
Hello,
When I try to boot my not new install of Arch Linux, it says "Cannot find root device [uuid]. I have tried to chroot and make a new config with grub-mkconfig and even format the boot partition. There are no logs from the day when the problem started to occur.
The machine is a MacBook Air 4,2 and the problem started to occur after a error occurred under an update to kernel 3.2.
