|Did you flunk out of high school? Your writing & spelling skills suck.|
OK, you used Boot n Nuke...it was totally unnecessary, but what's done is done.
Then you tried to install Ubuntu 10.04 & got some sort of error message which I'm fairly sure was NOT "cd or hd in error". We need to know the exact error message, word for word.
And I have no idea why you keep changing hard drives? That's not helping.
Are you 100% sure your Ubuntu disc is good? Have you booted off it & checked it using the "Check CD for Defects" option from the Ubuntu boot menu? Have you tried running Ubuntu directly from the CD without trying to actually install it to the hard drive? Do you have any prior experience with Linux or are you a newb?
