I used to get screens like that with win2k after messing with the boot records and stuff, u should give us the exact error and its code, I might be able to help you.
It can also be that there is a problem with memory dumping, or not enough memory.
Another famous screen is NTLDR missing, press any [censored] key to restart. Not ur error but ts fun too
The use of "hacker" to mean "security breaker" is a confusion on the part of the mass media. We hackers refuse to recognize that meaning, and continue using the word to mean, "Someone who loves to program and enjoys being clever about it."
