How to remove one operating system from dual boot windows?
You can install two or more operating systems on the same
partition or on same hard drive. For example you can install windows 98
with windows 2000 or Windows XP and also windows XP with Windows vista.
You can install both operating systems on the same partition (both on C:
drive) or on different partitions (one operating system on C drive and
other on D drive). But installing more than one operating system on same
drive kill the system performance.
In dual operating systems, when you turn on the computer, it gives you a choice of windows 2000 or windows
XP to use. Whether you have installed your both operating systems
on C drive or one on C drive and other on D drive, system store the root
files of the both operating systems on C drive, so you can delete one
any operating system with editing these root files. There is no any
direct method to uninstall one operating system; you can do this only
with format the partition or delete windows folder after editing the
"Boot.ini" file.
