I'm pretty rubbish when it comes to understanding partitions and the Ubuntu boot process. I have recently tried using the boot-repair application to re-instate my dual boot menu after installing Ubuntu 12.04 next to Windows 8. Unfortunately after doing this, I get grub rescue :(.
I have a log here that boot repair produced http://paste.ubuntu.com/6190172/.
I have a Dell Inspiron 15 and if on startup I press F12, I can choose Ubuntu or Windows to boot from. Choosing 'Ubuntu' gives me the multi-select that I would expect. How can I resolve this?
