I have been having a problem over the past week I have searched google but cannot find someone with the same problem as me. I have a computer approxiametely 5 years old with a Western Digital WD800LB 80gb hard disk and since last week it has been unable to boot up. Whenever i boot up I receive an error message saying, "DISK BOOT ERROR, INSERT SYSTEM DISK". I have tried inserting the windows xp disc but it gets to a blue screen saying "Setup is starting window" and freezes there while my hard drive makes a noise as if it powers ups-->starts spinning-->powers down and keeps repeating this cycle every 10 seconds.
I'm thinking maybe its some sort of hard drive problem; I have tried running Western Digital's Data Lifeguard Tools 11.2 and am able to run this from a boot disc and can access HDD information and maintenance utilities, it tells me that my HDD is only 8.4GB:S (its actually 80GB) and that my Master Boot Record (MBR) is corrupt I dont know what this means but I'm assuming this is the reason why my PC isn't booting?
Please help, how can I fix my hard drive so it will boot?
