Boot Issues
grub> set root=(hd0,msdos1)
grub> linux /boot/vmlinuz-(version) root=/dev/sda1 optional ro or rw
grub> initrd /boot/initrd(version).img
grub> boot
$ ls -l /
vmlinuz -> boot/vmlinuz-3.13.0-29-generic
initrd.img -> boot/initrd.img-3.13.0-29-generic
So you could boot from grub> like this:
grub> set root=(hd0,1)
grub> linux /vmlinuz root=/dev/sda1
grub> initrd /initrd.img
grub> boot
