I have an emachine that died on me. So I bought a refurbished HP DC7600 to use. It came with Linux but most of my programs require XP. I tried using Wine in Linux, but was only compatible for one of many software that I use. Is there a way to transfer my old XP from my emachine and transfer it into the HP even though my Emachine has one of those recovery disks with XP in it? But it would never ask me for a registration key to activate it though. I would hate to have to purchase another xp cd and key since Micosoft is no longer going to use XP by 2014. Could I transfer via USB/HDD? Extract the XP from the recovery disk?
