So I installed a PCI wireless card into my Dell DImension 4700. It didn't work too well so I pulled it out (after booting down the computer of course) and the PC rebooted fine. Then, after using my computer I got the blue screen of death and then everytime I tried to boot afterwards it told me my Ntfs.sys file was missing or corrupt (I assume the later). Now, I can't access Windows and only have a spare Windows Pro full CD-ROM. Not the Windows XP Home edition CD. Since Dell didn't include the CD-ROM what are my option on how to fix this.

Here's what I've done so far.

1. Reset the BIOS to default factory settings.
2. Changed the boot order having it boot from the CD-ROM.

So far it attempted to install Windows XP Pro once but before the install even began it said there was a missing file and it couldn't continue.

SO what course of action should I take now?
