Here's my problem.
1) I don't know what the program was that I was using. It said Do you want to take a snapshot of your hard drive?
I clicked yes.
2) It then said that it would reboot in DOS and continue taking a snapshot of my harddrive, and that it may take 2 hours to complete.
Again, I clicked OK.
3) It shut down and tried to reboot (in DOS, I guess) but I got an "error loading operating system" instead.
4) I don't have an ERD made yet.
5) I tried pressing f8 to go to the last known good config, but (of course) that only works with an OS.
6) I have no clue what to do next.
