Boy oh boy do I need some help.

My son got an infection on his pc. I'm not sure how or what he did but by the time it came to me, the startup repair would not fix the pc or boot it. The startup repair indicated the boot was corrupt. Silly me, I went to this site (http://support.microsoft.com/kb/927392) and followed the directions. Now the computer will not boot at all and I get the message there is no boot file. I loaded the OS Cd and the OS is not even listed as being available for repair.

I booted the pc using Ubuntu and all the files are there - and the OS - so I'm very confused and very desperate for help.

Thank you in advance.

The system is a Gateway running Vista 64 Bit

I'm very scared that I won't be able to fix this....

Also worth noting....the C: is labeled "Primary Partition"

There is an "X" Drive labeled "boot" that contains all the windows installation files.

The error message reads:
Windows Failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. insert your windows installation disk and restart your computer
2. Choose your language settings and then click "next"
3. Click "repair your computer"

File: \boot\BCD
Status 0x0000098
Info: The boot Configuration data file does not contain a valid OS entry

There are a few ways to go about this, but if you're already comfortable using a live cd like ubuntu, the easiest thing to do, in my opinion, is to just boot off of the ubuntu disk, copy all of your files to a flash drive or external hard drive, and then use your factory recovery disks and perform a complete destructive recovery. When you have a working system again, just copy your files back where they belong.

I don't really want to do that if I can repair the system.

Hi Chrissy, if you still can get in the Recovery Environment, type bootrec /scanos and let me know what comes back.

regards, Elise

The Windows installation files are located on the "F" drive (not X, my apologies) and are in a file labeled "Boot"

Would it be safe for me to reinstall the OS to the F drive? There are no other files on that drive except for the windows files.

Hi Elise:

I can get to a dos prompt. That's it.

I scanned and got this message:
Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.

You can try this- When you put your installation disk, instead of choosing start up repair, choose command line. Once the command window opens, change the drive from X to C and type "chkdsk /r" without the quotation marks. It will probably tell you the drive is mounted and ask if you want to do it anyway, so type y for yes. Let it run, and when it's finished, hopefully it will repair the damaged files. Worth a try, anyway.

Besides doing checkdisk as posted above, please do also the following:

At the command prompt type notepad and press enter.
Click File > Open. In the Open dialog, click Computer and look how many drives/partitions you see (besides X, which is the Recovery Environments RAM drive) and on which partition Windows is located.

Once you have noted that down, you can close Notepad.

regards, Elise

Chkdsk completed. The only "failure" was "Failed to transfer logged messages to the event log with status 50"

Computer contains:
Partition_1 (C:)
Data (D:)
Recovery (E:)
Boot (X:)


Chkdsk did recover the orphaned Windows file and restored it.
