Solved my computer suddenly says invalid system disk.

Specs: windows vista
It goes on to say " Replace the disk and then press any key". What disk? And where do I get a valid system disk? And what invalidated the one that was presumably already in it?

That means it's trying to boot from a hard drive, or a floppy disk or a USB drive, without the system files on it. For example, if you install a new hard drive and have no other bootdisk, like the vista installation disk, you'll get that message because there's nothing on the hard drive to boot up.

If you have a USB drive installed or a floppy drive with a disk in it, remove them and see if it then boots up normally. You could also check the boot order in cmos/bios setup--normally you'd have the CD/DVD drive as the first boot device and the hard drive as the second drive.

Did you make any changes to the computer or did anything happen to it between the last time it worked OK and the first time it didn't?

It's possible the port the hard drive is connected to is disabled in bios setup. It's unlikey that could happen on its own. You or someone else would have had to go into bios setup and mess things up. If that happened you can usualliy enable the default settings there.

Or it could be the hard drive has physically failed or has become corrupted.

You should probably post back more info about your system.

My guess is the hard drive died. Hopefully you have backups of all your important files, photos, videos, etc.

Error messages are of-course important but don't take them too literally. When something goes wrong the system often trots out the most likely message and throws it at you. If the hard disk is faulty it will assume it is missing (rather like a CD or DVD).

Always pop back and let us know the outcome - thanks
