OK, so I have noticed some HP hardware users are having issues installing Linux (different Distro's).
The CD would boot and get stuck at
ACPI: Assume root bridge [\_SB_.PCI0] bus is 0
... but don't cry ....
All you do is restart, and when you get the the install promt where you normally just press enter to boot, you type in the following and THEN press enter
linux noacpi nodma acpi=off
That should do it for majority of you guys...
