Comment:

I posted several days ago about windows not starting and getting the Ntoskrnl.exe, well I finally got the disk to got to Recovery console and fix that error, then I got a Hal.dll error, fix it. Rebuilt the boot file and now windows try to start then the "Blue Screen of Death" pops up and I'm now getting the following error: "Stop: C0000221[Bad Image checksum] The image Shdocvw.dll is possibly corrupt. The header checksum does not match the computed checksum." Seems like I fix one error and get another. I'm also doing an NAV Emergency scan. Any thoughts / fixes for the checksum / shdocvw.dll error???
Thanks
Rick A.

If you can't get in at present via usual XP boot... perhaps get yourself a copy of Knoppix (download an iso and burn to a CD, or buy it for a few $$$/£££ on CD). This is linux on a CD and is fully bootable; boot up with it and you're into full working linux system.

Then go on-line and do an on-line scan etc...

Once clean... if you can't boot up to XP afterwards... try a repair installation...?

Knoppix will also allow you to access data etc. and transfer off the drive entirely.

(There are pages in various lanaguages.)

I can get into the "Recovery Console",but that's it.. Do you lose your files/data when you do a repair?? I have rebuilt the boot file and fixed the first 2 problems, but now I have the third problem... Seems like i'm getting closer to a "Start", but errors keep popping up. At least last time, I got to the Xp screen. Farest I've been in 3 days..

Startup your comp, with a Boot disc or Startup disk in the floppy drive (without cd rom support)
At the A: prompt, type > sys c: and then press ENTER.
Take out the boot disk and then "Repair" XP by booting from the XP CD and selecting Install > Repair (NOT recovery console) > Fast Repair.
=============================================
Another way.
http://www.informationweek.com/windows/showArticle.jhtml?articleID=189400897&pgno=1&queryText=
Boot off of a clean Windows XP cd ( your bios has to be set to boot from cd rom 1st ) choose Install ( Not > To Repair a Windows XP installation using Recovery Console, press R ) at the first prompt.
It will then search for a previous copy of Windows.
When it finds your copy, it will stop at the next prompt and ask if you want to do a repair. Hit R at this screen.
If it does'nt mention a repair > DO NOT continue.
It will then copy a lot of files and appear to be doing a reinstall ( But its not. All your programs and data are safe, all you will lose, are your Windows updates )
This will allow you to add accounts to the system that will be administrator accounts, it will also fix most problems in XP.

The last item above - "another way" (post-6) is possibly the one to go for.

BUT - if possible - first slave drive to another working system and copy off all critical data (personal files etc.) to removable media; and then verify they are truly readable etc. - before restoring drive to its home and going ahead with the repair exercise...

According to the "Another Way" article shouldn't lose any data. Swapping drive wouldn't be easy it on a Laptop..

You are accountable for your own backups, one mistake by you & anything can happen.

well just did the repair, all files are intack, but when it's rebooted the first time, I got the following error:
STOP: c000021a {Fatal System Error}
The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000135 (0x00000000 0x0000000)
The system has been shutdown. And that's as far as it goes... Any suggestions????

Another way to backup, is using an adaptor that enables you to slave it & connect to a PC.
Your computer shop should carry. Very cheap.

Doing some more reading from the google links, doing a repair this way ( you lose your upgrades & hotfixes ) may be the best way. Backup your stuff 1st is still best, unless you want to take the risk.
