c;\windows\system32\autoexec.nt. The system file is not suitable for running ms-dos and microsoft windows applications. Choose 'close' to terminate the application.

The solution is to take these files from the installation disk and put them on the harddrive but I lost my xp disc. Is there any other way to fix this problem?ask m$oft for a replacement disk or the makers of your pci have same prob but i have windows xp cd what files should take wnd where shoul i but themThis is what I found in the help and support in xp. After reviewing it, It doesn't say that it applies to xp. I tried it and it didn't fix my problem. It said that I didn't have a destination. I gave up temporarily. If you have success, please let me know how!!!
