Vista Startup Repair says No OS files found on disk

My Toshiba Satellite booted up this morning to the Startup Repair screen. It autoscanned and said that it cannot repair the computer automatically. I've verified that all of my files are still there with the command prompt window.

I have tried using my Vista disc to repair the system and get the same message. I made a Vista RE disc on another computer and that came up with an error message saying that the BOOTMGR is corrupt.

When I look at the detailed log in the Startup Repair, it says:

Root cause found:
---------------------
No OS files found on disk.

Repair action: Partition table repair
Result: Failed. Error code = 0x490
Time taken = 15382 ms

---------------------
---------------------

I've already tried selecting System Restore from the F8 menu and it says that there are no restore points, which isn't true because I already had it enabled before this happened.

Any help is appreciated since it's my main PC. I've resorted to using my 10 year old desktop pc that barely runs XP just so I can troubleshoot this problem. :cry

Give this a read, recently used one of the mentioned CD's and a Kaspersky program to repair a W7 OS containing a "bootkit".

 

Thanks for the response. If I run Hiren's or UBCD, should I be looking to partition the drive or is there a utility that will restore the MBR? And at what point did you use Kaspersky's bootkit remover? From what I can see on their site, it has to run in either Normal or Safe Mode. I cannot get into either of those.

 

From the Vista RE disc and the Command Prompt:
Type in diskpart and hit <enter> button
Type in list volume and hit <enter> what do you see?
Typing exit gets you out of diskpart and also out of command prompt.

It would also be safe to choose Startup Repair from the list of five choices ending with command prompt and then Reboot and allow the automatic search for Windows/Vista partitions to see if it now recognizes the partition. But do give the diskpart information.
