I've copied OpenWrt to a partition on a hard disk, but can't figure out the correct GRUB menuentry to boot up correctly. That is, it starts up and a screenful of msgs wizz pass which end with...
Rebooting in 1 second.
Is there any way to get this saved anywhere so I can see what is missing?
It may be that I have the UUID wrong. If so can I just specify 'root=hd0,gpt7' or somesuch?
