View Full Version : [ubuntu] Installation fails before it starts
May 10th, 2008, 01:42 PM
Yesterday I installed Ubuntu without any problems on a laptop, which indicates no trouble with the CD I'm using. When I try to install it on my desktop though, it just wont work.
I believe there is a problem regarding the booting. I have set the booting order in the setup menu so that the CD/DVD-ROM is first in order. When I check the boot menu though, nothing have changed.
The CD runs though and I get to the first menu where I choose to Install Ubuntu. I see the loading screen and then a lot of text is printed on the screen which is hard to make any sence out of, but I guess it says that the installation process was locked. I get no further from here.
I tried the option of "Help me run from CD" without any success.
My computer is a three year HP Pavilion.
What should I do?
Thank you in advance!

Try the Alternate CD.
Here are a few links om all kinds of HP:

I tried the Alternate CD and also some of the codes provided on the sites you linked. But it still wont work. I cannot figure out the problem.
By the way, I don't have a HP laptop but a desktop if that makes any difference. The boot menu is version 3.04.

You might need some boot parameters. Here are some guides and collections of them. Try your luck:
noapic nolapic acpi=off pci=noacpi irqpoll pnpbios=off vga=0x317 vga=791

The VGA part of your boot parameter caused problems, but I accessed the installation with noapic nolapic acpi=off pci=noacpi irqpoll pnpbios=off. It seems it inactivated my USB-ports though as my mouse and keyboard stopped working. I've read that can happen with noapic.
How can I keep this from happening?

Use the boot parameters one by one and start adding others until you find the right combination.

Okay, I have now been able to locate the parameters that let me access the install menu. The problem is that no matter how I combine them the USB ports are shut down and I cannot use the mouse nor the keyboard making it impossible to actually perform the installation.
The working boot parameters are as following:
acpi=off (lacpi=off) pci=noacpi irqpoll
How can I prevent the USB ports from shutting down?
