inaccessible boot device error after motherbord failure and replacement

[HoooDIS]

I have a problem, I replaced my motherboard after it died and now during startup I am getting the STOP ERROR inaccessible_boot _device. I am running Windows 2000 Server and would rather be using XP. The STOP ERROR hits while trying to load windows. It is recognizing all of my memory and hardware on the startup but crashes right after the windows screen pops up. I would love to format the c drive and start over but when I boot from a startup disk it tells me that the C drive isn't there ("invalid drive specification.") I am fairly new to the tech world and would like to fix this myself. THANKS for any help

The reason your new mb will not boot up with the old hd is that you probably installed proprietary drivers for your chipset. Since the old mb died I do not know of any way to remove the drivers. I am not sure if you can boot in safe mode and remove them that way.
When you use the boot disk, are you using fdisk to remove any non dos partitions? I would think you have ntfs that is why your dos boot disk will not see the drive. If you need instructions on running fdisk, post back and someone will help you.

decided to change boot pattern in the BIOS and boot from a new XP CD. I'll letya know if this cleared everything..... thanks again. I'm new to this room but will be back often...
