this is exactly what the prompt says:
secondary master hard disk error
Press F1 to resume. Core 2 Quad 9450/4GB RAM/XP Pro.
I hit F1 and it goes into the XP logo and spins.....and spins.....and spins.....and spins...and spins.
Before if I rebooted into safe mode and then booted again it will go into normal windows. If nobody answers before I do that, I will do that again--I need to work.
edit---ok, this time I let it spin and spin and it eventually booted and a prompt came up that said, "found new hardware". Sad to say, the rest flew by and I couldn't see what it said. I know it had a "T" in it and of course my hard drives when going to system and checking have "T's" in them. I know this might sound dumb. I'm a musician forgive me. ^_^
One more edit--ok--yes, it did boot, but the partition is not there--and it is my main work data folder for my music projects. I will definitely now re-boot.
