Yesterday I upgraded my hard disk to an old 7200 RPM 15 GB IBM Deskstar I had. I simply cloned the disk with Ghost and everything was fine. However, now, when I boot my computer I randomly get "Error Loading Operating System" errors (sometimes these are replaced by a standard "Please insert a system disk..."). The disk is always detected at POST, but I often have to restart the computer several times, unplug the PSU, or cast a dark spell before it detects the boot partition. It's getting quite annoying, and I'm running out of things to sacrifice. Joking aside, does anyone have any ideas?
What OS are you running? If Win9x/Me, did you try System File Checker/Scan Disk? W2k Check Disk? then maybe defrag. You may have a corrupt .dll/.vxd or a share violation, could be a drive/program mapping issue. A good diagnostic program may help. As a last alternative reinstall the OS.

I ran chkdsk /r and so far no bad sectors, but it still randomly doesn't boot, always with the same error even though it's recognized correctly in the BIOS. Anyway, I'm getting off of this ship before it sinks, and will be buying a 60 GB Maxtor or Seagate in the next few days.
Ouch...I had that same HD. It died on me. Anyways, get <A HREF="http://www.storage.ibm.com/hdd/support/download.htm" target="_new">Drive Fitness Test</A> free from IBM, and do a standard and thorough check of your hard drive. Chances are, it's about to die.
I hope you've backed up your stuff. If not, stick it in a Ziplock back, throwing it in the freezer for a couple of hours, and try to retrieve the data from it. I have the pdf file on it if you want more information and testimonials of this working.
I have more in my ramble about it at my site below.
