“During both the keynote and a Windows Phone 7 session here at TechEd North America 2010, Microsoft showed off a subtly newer build of Windows Phone 7 that features a few visual changes over the builds we’ve seen not too long ago from Microsoft MIX and certainly its debut at Mobile World Congress 2010.”
The MBR partitioning scheme cannot address volumes larger than 2Tb. GPT partitioning can be used to overcome this. UEFI is not a hard requirement to boot from GPT; BIOS-based booting just loads the first sector and executes it. BIOS does not limit the partitioning schemes that can be used; that is determined by the software on the disk, ie., the bootloader.
What this article meant to say is that GPT BIOS bootloader support is less than universal, and moving to UEFI gives GPT boot support without rewriting the bootloader. Except moving to UEFI really is rewriting the bootloader…
Umm .. think you want this article mate…
