Ubuntu 11.10 installed from LiveCD will not boot.

Asked by Roy Gannon on 2011-10-17

Tried to upgrade from 11.4 to 11.10 with Update Manager...System would not boot.
Loaded 11.10 from Live CD (needed to hold down Ctrl key to get Ubuntu screen...also needed F6 for acpi=off before 'Install Ubuntu' would work).
System worked fine from Live CD. Download seemed to go fine.
On reboot...purple screen, no cursor, no response.
Reboot while holding down CTRL brings up 'GNU GRUB version 1.99- 12ubuntu5' screen and lists:
Ubuntu, with Linux 3.0.0-12-generic-pae
Ubuntu, with Linux 3.0.0-12-generic-pae (recovery mode)
Previous Linux versions
Memory test (memtest86+)
Memory test (memtest86+, serial console 115200)
Pressing 'Ubuntu, with Linux 3.0.0-12-generic-pae' brings blackscreen and blinking cursor at top left and then black screen with
'BusyBox v1.18.4 (Ubuntu 1:1.18.4-2ubuntu2)built-in shell (ash)
Enter "help" for a list of built-in commands.
(initramfs)'
This screen does not change without reboot.
Pressing 'Previous Linux version' brings
Ubuntu, with Linux 3.0.0-12-generic
Ubuntu, with Linux 2.6.38-11-generic-pae
Ubuntu, with Linux 2.6.38-11-generic
Ubuntu, with Linux 2.6.32-33-generic
each of the above also has a recovery mode.
Pressing 'Ubuntu, with Linux 3.0.0-12-generic' brings blackscreen and blinking cursor at top left and then black screen with
'BusyBox v1.18.4 (Ubuntu 1:1.18.4-2ubuntu2)built-in shell (ash)
Enter "help" for a list of built-in commands.
(initramfs)'
This screen does not change without reboot.
Pressing 'Ubuntu, with Linux 2.6.38-11-generic-pae' same as above.
Pressing 'Ubuntu, with Linux 2.6.38-11-generic' same as above.
Pressing 'Ubuntu, with Linux 2.6.32-33-generic' brings up Ubuntu 11.10 login screen, but the mouse and keyboard do not respond.
Computer - Dell DX-4720
Processor - Intel Core 2 Quad Q8200
Memory - 3 GB
Any help would be appreciated.

Add the acpi=off to the 3.0.0-12-generic boot, see if it helps. You may also want to try the boot option:

nomodeset

This can help too

More info.

Tried to run other distros LiveCD's but none would boot. This made me think it was a problem with grub.
I reinstalled grub(learned how here: http://ubuntuforums.org/showthread.php?t=224351) and after reboot everything works again.
Hope this helps someone else with this problem.
