Not sure, I tried to install Windows Vista, best OS IMO.
Upon making a NTFS Partition, Vista came back and said the Hard drive is partitioned as GPT, a new format to me. Maybe has to do with the Hard Drive being 1.5TiB. Still... it will not let me install windows Vista regardless of what I do. I made the partition 60GB of NTFS and still won't let me install Vista. So I give up. This GPT format is obviously far superior to NTFS when it comes to OS.
GPT and NTFS has nothing to do with each other.
NTFS is the file sytem, it's counterpart, for example, is FAT32.
GPT is the layout of the partition table. It's usually MBR, but GPT has is being used more frequently now with bigger disks, etc.
All that said, it should have nothing to do with the ability to install Vista. It may have something to do with this though, but not sure if it applies to you, or what it means:
Q. Can Windows 7, Windows Vista, and Windows Server 2008 read, write, and boot from GPT disks?
A. Yes, all versions can use GPT partitioned disks for data. Booting is only supported for 64-bit editions on UEFI-based systems.
I am on a 64bit system. So not entirely sure on what to do here. I know all that. It still refuses to install Vista on the partition I make and still says it is formatted as GPT even though I create the partition in NTFS and FAT32 is not even an option
I might have to buy a copy of windows 7 and try and see if that works. I've read more people are successful installing a partition of Windows 7, than Vista or XP.
