I can't get out of grub + you need to load the kernel first
Try the following steps:
ls [to see paritions]
Then ls root directory of each, to find the one linux installed on. e.g:
ls (hd1,6)/ [let's assume linux is installed here]
linux (hd1,6)/boot/vm [===> press TAB to auto-complete] root=/dev/sda6
initrd (hd1,6)/boot/ini [===> press TAB to auto-complete]
boot
Hopefully! in linux:
sudo update-grub
grub-install /dev/sda
If, for any reason, you couldn't make grub work. Install Boot-Repair: https://help.ubuntu.com/community/Boot-Repair
