I run a dual-boot Windows 7 / Xubuntu 10.04 machine. Recently Xubuntu crashed and refused to boot (straight to busybox) when I selected it from the GRUB menu. (Windows booted just fine.) I downloaded and ran Boot-Repair, which I believe fixed the problem with Linux, but I cannot check this because now the GRUB menu does not appear at all. The machine boots straight to Windows (which still works fine).
I tried holding Shift during boot-up but still no GRUB menu.
I have the output of Boot-Repair here:
I think the system is booting from dev/sda2 instead of dev/sda6, or wherever GRUB is
located. Is there an easy way to change that?
