@ daddijonez:
I checked that in the BIOS, its still trying to boot from the hard drive.
I'll try deleting the two small partitions, then reformatting, then reinstalling.
If this for some reason doesn't work, do you reckon the Dell technicians can fix the computer completely again? I reckon they can, it's not like im messing with the BIOS or anything, just the hard drive. I just don't want to completely ruin my computer in an attempt to fix it.
By the way, thanks for the replies kemical.
