Ok so today i got an old used IBM T30 thinkpad. I was aware it had boot problems and am now trying to solve them. When booting from the original hard drive it will boot about half the time so i replaced the hard drive with one from my old computer. After doing this it simply started up and brought me to a black screen with a blinking cursor. On seeing this i too a version of Linux Ubuntu on a disk and attempted to boot from that. Same problem. I'm certain its a hardware problem but id like to narrow it down. Thanks in advance.
