since Windows2000 thinks it has two disks, the boot.ini file was written to.
Boot from a floppy to check this file out (c:\boot.ini).
*NOTE* use the attrib command in DOS to remove its attributes
c:>attrib -h -r -s boot.ini
Make sure that the file is OK. You might have to change some values here, but this is a very, very common problem. check out the documentation on the boot.ini file.
c:\boot.ini
multi(0)disk(0)rdisk(0)partition(2)AdvancedServer
it is more than likely that you'll have to change the partition number (which is 2). When W2K boots, it tries to boot to the boot partition which you'll have to determine.
W2K can only have 4 primary partitions OR 3 primaries and 1 extended OR 2 primaries and 2 extended and so on. However, in a typical W2K installation (you'll have to know your partition table for this) the #1 partition is your system partition and #2 is your boot partition. When you create these partitions, they are numbered primaries first, then extended. (ie if your configured c:=primary, d:=extended, e:=extended, f:=primary, c: will be 1, f: will be 2, d: will be 3, e: will be 4). If this is confusing, which probably is, do a trial and error with the partition number in boot.ini (values are from 1-4) until you can boot that sucker.
hope this helps and good luck on your final.
