Invalid system disk Error

by bonnilyn55 / March 4, 2010 6:05 AM PST

Hi All,

I know that a quick google search will give me a bazillion hits on this topic, but I am having one heck of a time trying to find anything that will help..

On of our employees brought in a HP Pavilion with Windows ME and I am getting the error "invalid system disk..." I made a bootdisk from bootdisk.com and have tried the much suggested sys C: only to get the "bad command" response. The disk has the sys.com file on it and I have ran scan disk.

The CD Rom driving is constantly turning and looking for something, but I'm not sure what.

Any ideas how to get this thing going?

Invalid system disk Error

The Invalid System Disk error can occur for a number of reasons. In most cases, this error occurs after an operating system install, reinstall, hard drive replacement or motherboard upgrade.
Start your PC by using the Windows Startup disk, and then use the sys command from the Windows Startup disk to restore the system files to the hard disk. Some systems use built-in anti-virus software that must be disabled in the computer's BIOS.

Hi All,

Sorry, I should've posted that I found the problem. I couldn't use the coveted sys C command and I couldn't load from the CD Rom to run the recovery.

I ended up replacing the CD drive and it fired right up with the discs. I was able to run the recovery and kept all my data.

Thanks..

This worked for me as well.

I was upgrading an old pc from xp to windows 7. I was getting the system disk error when I tried to install/load from the Windows 7 disk after a clean install. I replaced the CD burner drive with a dvd burner drive and it installed quickly after that.


Thanks
