This question already has an answer here:
I have a Compaq 620 with 4 partitions on the hard drive. The primary partition has Windows 7 installed on it.
I want to dual boot this computer with Windows 7 (Korean version) installed on the other partition. How should I go about doing this?
I do not want the Korean version to interact in any way with the English version. I also don't want to mess anything up so I thought I should ask here first. Please let me know how I should go about doing this, where things might go wrong, and how I can avoid them.
