autoch program not found - skipping autocheck

I have a dell dimension 4600 running Windows XP Pro. I removed Itunes and been able to boot since. I get a blue screen indicating autochk program not found - skipping autocheck. It gets stuck at this point and won't boot. I've gone into recovery panel and can't get anywhere. Although I was able to see the autochk.exe file in DOS under the Windows directory.

Now I'm hoping I can at least get a few files from the DOS prompt and then rebuild the system. When i get to the DOS prompt it won't let me change to my document and settings folder. It says access denied.

Two questions I hope someone can help with--
How can I fix the reboot?
OR
How can I get my files copied to a external drive?

Any help is greatly appreciated.

 

How do I do this with a disc drive or flash drive? I tried to find how to Create an MS-Dos Startup Disc.

2) Create a bootable MS-DOS disk for Windows

In Windows XP

* Place a blank floppy disk in Drive A
* Open My Computer
* Right-click on Drive A (floppy drive)
* Click on Format
* Check the box for "Create an MS-DOS Startup Disk"
* Click Start
* Click OK to the warning about formattting the disk will erase all data
* Click Ok to Format Complete
* Close the Format Disk window

Thanks for the quick response.
