So I just installed 11.10 on my Dell Precision T5500 from the live cd. The live cd worked fine, but when I attempt to boot from hard drive I end up at the BusyBox prompt. However, if I simply type "exit" and Enter it continues booting and I get the Ubuntu graphical login screen. How do I fix things so I don't stop at the BusyBox prompt?

I found an interesting similar problem at, but can't exactly implement the solution since the /boot/grub/menu.lst file doesn't appear to exist in 11.10.

Any ideas? It would be nice to be able to reboot my system remotely.

You can try the solution you found by editing /etc/default/grub instead; edit the line labelled GRUB_CMDLINE_LINUX_DEFAULT and run sudo update-grub to make the changes take effect.

You should end up with something like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash bootdelay=90"

This has the same effect as editing menu.lst (actually, it's now called grub.cfg) but in a way that the Ubuntu packages understand, so when a kernel or grub gets updated, the changes will persist. You generally don't want to be editing the grub config manually.

It works! But the option I had to use was "rootdelay", not "bootdelay" as in the blog I came across. Thank you, Caesium! – Clark Dec 7 '11 at 18:18
