Tap F8 while rebooting and choose the Last Known Good Configuration. See if that gets you back.
OK, so everything is working fine on my (other) computer yesterday afternoon, I return home this morning and notice that IE and Outlook are running *very* slowly. I reboot the computer, and it doesn't boot into Windows. It stops and gives me a "missing/corrupt file" error, and then it has a path I don't quite recall, and then the file name: ntoskrnl.exe.
I am running Win2000 Professional on the computer in question.
Can anyone get me back up and running? I do not have a Win2000 CD-ROM, unfortunately, but I do have a Win98 CD-ROM, and I believe Win95 as well, if either of those can help.
And please, walk me through it like I'm an idiot.
Thanks very much!
