Vista Boot Problem

[ComputerBrian]

Just built system with Vista Premium. Now it will only boot into Vista while the original DVD Vista disk is in the cd-rom? If disk isn't in cd-rom, I get the error Disk Book Error, please load repair disk. I can't see anything in the boot options or BIOS that is glaring at me to change. Any ideas?
Thanks,
Brian

unfortunately, the only thing that comes to my mind is hard disk failure, since I recently had one. I did not get this exact message, but I did get Blue screens, at loading time, and eventually got to the pooint where not even the "Safe mode, Safe mode with Networking, Safe mode with Command Prompt..." would show up.

Got myself a new FUJITSU disk, doing well for now.

To test the disk, go into your BIOS (F12, I think) and see if you have a Hard disk Diagnostics option, or anything of that fashion.

I have Phoenix Bios, and it confirmed a failure. Another way to test it, is to move some big, but not important files around and around in different volumes, and if you either get an I/O error message, or your computer locks up during the operations, then you'r in hot water. You will need to buy a new HDD, I personally do not think Hard Disks are repairable.

Hope I am wrong...
