Linux machine has booted into grub prompt
From AcrodusWiki
This occurred when installing ARCH for the first time. On boot, i was presented with the grub shell. If prompted with grub> then this means grub loaded normally. If prompted with grub rescue> this is worse, and at the time of writing this i have not been in this situation.
In my situation a separate boot partition was present, with the rootfs and swap on lvm logical volumes. There was a kernel image and initrd.img present on the /boot.
The ls command showed me my two partitions that was promising, although it could not interpret the rootfs, maybe because it is on a logical volume?
I ran the below commands to successfully boot.
set root=(hd0,gpt1) linux (hd0,gpt2)/vmlinuz-linux root=/dev/vg0/rootfs initrd (hd0,gpt2)/initramfs-linux.img boot
This successfully booted.
