I'm attempting to install Ubuntu from a 12.04 live CD.
A few boots have gotten me
(initframs) in BusyBox. During one attempt, it actually said it had loaded Ubuntu and gave me a command prompt, before quickly taking it away.
After the working attempt, the HDD was removed from the BIOS menu for some reason, but was auto-detected on a boot into Windows.
I haven't got a clue what I'm doing wrong. I don't get the little Ubuntu graphical splash while it boots either, but F6 (or rather spamming many keys) will display a list of the various [starting]/[stopping] it's doing.
