Wikipedia defines it as a partition layout standard for a hard disk. GPT, an acronym
for GUID Partition Table. GPT actually features a number of improvements over the
old Master Boot Record (MBR) method of partitioning used with PC BIOS.
The following advantages result from GPT:
GPT uses 64-bit values for addressing purposes, which can address up to 9.4
Support for multiple partitions, 128 partitions in most configurations. The
number of primary partitions is limited to 4 for MBR partitions.
GPT has two tables: a primary one, and a secondary one, for backup purposes.
Each partition can also be given a descriptive name consisting of 36
Limited by space, I hope you could consult more advantages yourself from internet
It is true that GPT disadvantages are less than its advantages. GPT’s disadvantages
or problems are predominantly related to the issue of compatibility. Older operating
systems, such as Windows XP 32-bit, may not be able to work with GPT. Sometimes,
your computer should support UEFI if you want to use GPT partition. The table below
lists specific situations:
|Operating System||Data Access||System Boot|
|Windows XP 32-bit||Not Support GPT||Not Support GPT|
|Windows XP 64-bit||Support GPT||Not Support GPT|
|Windows Vista 32-bit||Support GPT||Not Support GPT|
|Windows Vista 64-bit||Support GPT||Support GPT(Need UEFI)|
|Windows 7 32-bit||Support GPT||Not Support GPT|
|Windows 7 64-bit||Support GPT||Support GPT(Need UEFI)|
|Windows 8 32-bit||Support GPT||Not Support GPT|
|Windows 8 64-bit||Support GPT||Support GPT(Need UEFI)|
After you have known about GPT partition, I think you should have a third-party GPT
partition manager helps you manage and optimize GPT hard drive. AOMEI Partition
Assistant is recommended. First, it can easily exchange partition types between MBR
and GPT. It also allows you create, delete, format, convert FAT to NTFS,
change primary to logical partitions on your hard drive. With only a few clicks you
can resize, move, hide existing partitions
- all without corrupting your data.
Additional features of AOMEI Partition Assistant:
Seen from the above table, there are four Windows operating systems: Windows XP,
Windows Vista, Windows 7 and Windows 8. AOMEI Partition Assistant supports all of it,
both 32-bit and 64-bit and the latest Windows 8.1.
For Windows Server, AOMEI Partition
Assistant supports Windows Server 2003/2008/2011/2012/2000, also 32-bit and 64-bit. In
short, AOMEI Partition Assistant is an excellent partition software, if you try it, it
won’t let you down. Easy to use and very safe.
