running windows partition in ubuntu

[compdoc]

>  I have a dual boot server with xp and ubuntu - each on their own drive.
is there any way to use virtual box or something similar to run the xp OS a
guest to ubuntu - that is already installed on the other physical drive than
ubuntu is installed?



No, you cannot run it from a disk that way, but you could copy XP's disk
into a VM, which runs from a virtual disk that is located on the old drive. 

Simply put, you basically clone the XP system as a file somewhere, erase the
drive, set it up for use with Virtualbox, and then copy the clone back into
the VM. 

Again, that's the short version. It's not a trivial procedure, but it can be
done.
