Hi all I have a GPT protected disk from my laptop that I want to scan for viruses, I usually just put it in my desktop but with this new Windows 8 pc I have the disk manager in my Windows 7 64 bit machine is asking me to initialize the disk to either MBR or GPT. If I initialize the disk on my Windows 7 desktop with GPT will I be able to boot from it when I reinstall it in my Windows 8 laptop?
