Strange error on bootup, after POST

A Toshiba laptop, with Windows Vista Home, will not boot past the POST screen. It just displays a black screen with DOS-type font and the following error:

!!0xc01a001d!! 18216/52483 (\Registry\machine\schema\wcm://microsoft...

The text is flashing very very fast as though the machine is continually processing information, however the error message doesn't change.

A Google search shows that many other people reported this problem after installing SP2, but unfortunately the client is unsure what service packs (if any) are installed on it. There was no fix for the problem lsited anyway.

We've done CHKDSK scans using the UBCD, run several virus/spyware checks, reseated the battery and reseated the memory. Any other suggestions?

During startup you'll see the Vaio Logo.
Once you see the Logo press F10 and you'll be given a couple of options.
One is to create recovery disks.
Other options allow you to reboot back to factory settings, but wiping anything on your Hard Drive.
Use the link I gave to see what other options Sony Vaio has.
Good luck with it.
You do not say if you can get into Safe Mode, you only mention "Last Known......"

1. Restore Point:
Try tapping F8 at startup, and from the list of startup selections, select Safe Mode by using UP Arrow Key to go there > then hit Enter.
Try a System Restore once there, to pick a Restore Point before your problem..
Click Start > Programs > Accessories > System Tools > System Restore > pick a different time > Next > etc

Sony Vaio Recovery options: key in your Model number there.
As is the case with most computer/laptops these days, they do not come with the proper Vista Disk to do Repairs with; only Recovery Disks.
If yours falls into the above category, download the ISO file at the supplied link, and make a Bootable Disk from it.
Go into your Bios/Setup, or Boot Menu, at startup, and change the Boot Order to make the DVD/CD drive 1st in the Boot Order, then reboot with the disk in the Drive.
At startup/power on you should see at the bottom of the screen either F2 or DELETE, to go into Bios/Setup, or F12 for the Boot Menu.
When you have changed that, insert that Bootable Disk you have made in the Drive, and reboot.
You can do a Startup Repair, System Restore, etc with it.
Read all info at the website about creating and using it.

Try to boot into a XP CD and run a repair on the file system.

This guy has it laid out pretty well:

"A Repair Install will replace the system files with the files on the XP CD used for the Repair Install. It will leave your applications and settings intact, but Windows updates will need to be reapplied. "

I was really hoping somone out there had seen the problem and knew just what to do, but I'm just going to copy drive contents to a USB drive and re-image the disk. Points to pinascode for thoroughly reading my posts/problem description, and confirming my choice to re-image in case there was no solution.
