Invalid system disk... with a catch

Upon boot I'm getting an invalid system disk or disk error message. sounds simple enough. but if i pop in a bootable cd, and NOT boot off of it (When it says press any key to boot off of cd), it then proceeds to do the normal boot process.

any ideas?

nope. it goes cd, then hard drive.

even if i switch the order to HD first, it's the same thing. I get invalid system disk errors... which makes no sense because it'll boot off the hard drive after i stick a bootable cd in there and NOT boot off of it :(:(

and obviously im running win 7.

tried that. the utility says it finds errors and corrects them, but next reboot the same thing happens. It's quite odd lol. i mean it really only adds like 10 seconds to my boot up time, but it's still annoying :(

Has it always behaved that way at boot, or is it only since you installed Windows 7?

Is the CD drive on a PATA connection and the HDD on a SATA connection? If so, does disconnecting the CD drive enable the PC to boot from the HDD? In which case, check to see if a BIOS update is available for your motherboard.

There are few commands which you could use in Windows Recovery that may fix the error message (like fixboot, fixmbr, Bootrec.exe]

For windows Vista/Windows 7 click here http://support.microsoft.com/kb/927392

To check the integrity of your hard drive, use a too like Seagate SeaTools (for windows or dos). “Its a diagnostic tool that helps you quickly determine the condition of the disc drive. It includes several tests that will examine the physical media on your Seagate or Maxtor disc drive and any other non-Seagate disc drive”. Download from here http://www.seagate.com/ww/v/index.jsp?locale=en-GB&name=SeaTools&vgnextoid=4b7300bc350ce010VgnVCM100000dd04090aRCRD


You are advised to back up all your important data, before attempting any fix.
