Hi after a fresh installation on windows xp i installed ubuntu 8.04.

When i turn on my laptop there are 4 choices:
ubuntu 8.04
ubuntu 8.04 recovery mode
ubuntu 8.04 memtest
windows xp

when i select time first option the screen will just flicker and turn blank black

when i select recovery mode some text would show and would eventually hang with the last 6 lines ACPI Exception (processor_core-0816): AE_NOT_FOUND, Processor Device is not present [20070126]

when i select memtest it works

when i select windows xp it also works
