As far as I know Windows should do the UEFI installation automatically (because it sees that you've enabled the UEFI boot option), so this procedure is only needed in case it doesn't start.
Also, it should benefit even HD owners.
I will write back when I get my new PC: MSI P67A-C45 (has UEFI), Samsung Spinpoin F4 320GB & Windows 7 64-bit.
I know that these procedure divides the HD in GPT partitions and that GPT's most benefit is compatiblity with 2TB HD (and I only have a single 320GB drive used as a single partition), but I still want to use it because UEFI is better than the BIOS and GPT is better than MBR. You can replace better with newer if you don't agree.
I only hope that Windows starts automatically the UEFI installation becuase I've read of problems with UEFI installation done through USB flash drives (but I could still make a modified Windows 7 DVD). What do you guys think?Edited by link_90 - 2/11/11 at 2:44am
