Hi, I started using Raid_0 between 3x 2TB hard drives for ~5.6TB total, and converted them to GPT to boot using them. I also updated my BIOS to UEFI thing, in order to install windows 7 ultimate on <2.2TB hard drive. The problem here is, after 2 days of installing my programs and tweaking and customizing my computer, Windows Loaders couldn't identify the partition table because it's GPT, and so, couldn't activate it. Many Frequently Asked Questions suggest changing from GPT to MBR but i can't do that as I wouldn't be able to boot from the Raid_0 I made, because of the limit on installing windows 7 on hard drives <2.2TB. I did a lot of googling and searching, but no activation method seemed to work. 27 Days to activate. What can i do about this situation? And are you planning on making a Windows Loader that works with GPT? I would be more than happy if i could even activate it manually to avoid losing my customizations, but i do not have any experience such as BIOSes .. Just a normal user.. I am hoping your deep experiences in this field can help fix my problem. And accept my thanks.
