cant install ubuntu

[Barry Pohlman]

Just some quick questions so that I may understand your problem better.
As a quick note, Do not do any of these steps on a production machine
or a machine that is not yours. You may take it off-line.

First a quick fix that you can try. Go into the BIOS settings when the
computer first boots. Set the BIOS to default settings and reboot. See
if that would fix your issue.



Have you tried any other version of ubuntu except the 9.04 disc?
	There are alternative install discs that may provide help.
	Also you can try the 8.04.2 LTS version to see if it will load.


Do you have the capability to update the BIOS?
	Not for the new user or feint of heart but your problem may be a
	bug in the BIOS that has been fixed with updates.
	!!! Warning. Do not update BIOS if you do not feel confident in	
	doing so. Can cause permanent damage to the machine if done
	unproperly!!!!!!



Good Luck
