Dell X200 Coldboot is fine, reboot throws "Operating System Not Found

Well, from a cold start, the drive seems to spin up quick enough to allow BIOS to see it and I buttumed the drive continued to spin through a reboot but I guess it is possible the computer interrupts power that BIOS skips detection of the HD and then throws the operating system error. But if I shut the machine off, and turn it right back on, BIOS detects it perfectly fine and fast.

There are no options in BIOS to speak of regarding HD settings, which is quite annoying as it'd be nice if there was at least the throw-back to the days of IDE Pre-Delay.

I checked Samsung's sight for a manual and turned of was was essentially the little 4x3 notecard that came with the drive. It describes jumper settings and such but this is a laptop, with a single IDE connection for the HD and both the old drive and this drive are set to "master". The only other option I can set it to that makes sense is cable select but that seems like it'd complicate the situation.

Do you know if there is a way to envoke some kind of "Expert" mode on the Dell BIOS's?

I'm also going to try running the Samsung Utility on the drive as well as Dell Diagnostics to see if that reveals any hidden settings.

Thanks so much for the quick reply!
