It could be a bad burn. You could try a media test or re-download the ISO.
Otherwise, I would imagine that the hard drive is bad.
I know I have done a media test before, but for some reason I cannot find the option now o_O where is it located?
and I do not think the hard drive is a lost cause. when I put it in my windows machine, "explore2fs" read the disk perfectly. and the WHOLE disk, as I did a complete dump of the whole disk. If anything is wrong with it, I personally think it is something that a reformat will fix.
thanks for the help btw everyone. And sorry for any attitude I might have had so far. (I don't actually know if I have or not, I just felt like thanking everyone and covering my butt if I have been mean or anything

)
