OK....I have perused all the discussions here about this subject but none of the suggestions seem to be working for me. Here's the story.....I built a new computer recently (first timer) and had it running fine except for some irq conflict issues. Then I started doing things I wasn't sure about, one thing lead to another and BAM! I'm dead in the water! My problem started when I decided to format my HDD but just before I did that I was getting an error message concerning winnt\system32\drivers\ntfs.sys. So, I stupidly sent it to the recycle bin. Then I formatted the HDD. So now when I try to boot up to reload Windows 2000 Professional I get the error message "winnt\system32\drivers\ntfs.sys missing or corrupt". I've tried to boot with a Windows 98 SE startup disk w/cd driver and can get to an A: prompt. I can't figure out how to load Windows 2000 Pro from my cd drive. I've tried an ERD to no avail. Can someone out there help?
