I made what I guess was a mistake with a backup software program I'd been using. I hit "synchronize" instead of backup and when I tried to cancel, it said I'd lose all my harddrive data if I did so, so I let it run. But at the end of its process, it asked me to insert the CD with the initial MS Office XP Professional software. But Dell didn't send the CD with my Inspiron 6000 (just a paper facsimile telling me "Your new computer does not require an operating system CD or drivers CDs."). When I then rebooted the computer, all I get is a screen reading:

"Windows could not start because the following file is missing or corrupt: system32\DRIVERS\isapnp.sys

You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select 'r' at the first screen to start repair."

I've tried advanced startup commands to use Safe Mode, Safe Mode with networking, Last Known Good Configuration, etc., but none of those options work.

Is there any solution to this without a Setup CD (I tried a setup CD for Windows XP Professional that came with my wife's Inspiron 8600, but no go)?

Thanks for any help you can give me.

Dell's generally have a system recovery patition that you can access by pressing a key as the system boots (try F2 to enter the BIOS and see if it's there).

To use a Windows CD to repair this, you'll need a CD that's similar to the OS installed on your system (an OEM CD with either XP Home or XP Pro)

Worst case, contact Dell and order a set of CD's.

Thanks, John. I'll give it a try when I get home this evening.
