GUID or MBR. What's on your Hard Drive?
« on: June 06, 2011, 08:55:17 AM »
GUID or MBR. What's on your Hard Drive? You may never need to know. Or maybe not knowing could hurt your PC experience.

The new GUID is the future.
The old MBR is dead.


But the change is not well-liked.

The purpose of this post is to help any user understand the problems of mixing Windows XP with Vista on the same disk drive. But if you install XP first, then Vista, it works just fine. It is when yhou want to repair or install XP again, there may be issues. A better choice is to put XP on its own hard drive.

This is an old thread on
www.daniweb.com and echos comments found elsewhere. It was last updated three months ago.

The woes of a GUID Partition Table

GPT, an acronym for GUID Partition Table, is likely something you've never heard of before. Perhaps that's a good thing. Throughout my usage of GPT, I've come to see that it's a total and complete waste of time.

What is GPT, anyway? Wikipedia defines it as a partition layout standard for a hard disk. They go own to say that "it is a part of the Extensible Firmware Interface (EFI) standard proposed by Intel as a replacement for the outdated PC BIOS, one of the few remaining relics of the original IBM PC."....

He got a lot of flack for saying that. Click on the link and read the whole story and the responses from others.

Windows Vista and 7 do not use GPT by default and they must be specifically chosen while partitioning a drive or during setup. Additionally, they are only supported by the 64-bit editions.

Not sure why this is earth-shattering news...
Since Win2K every Edition of Windows made changes to the MBR in a dual-/multi boot setup...

Why is this news now ? /

Because the king of the Potato people said so. Anyone who disagrees must fly on a three-seater magic carpet and plead with the king of the Potato People for leniancy.
