UEFI GPT system combination is better compared to the traditional MBR BIOS system
One is that GPT doesn’t limit
partition quantity, MBR supports only at most four primary partitions. GPT can
support partition size more than 2TB, exceed the partition size’s maximum limit of
One of UEFI’s advantages is operation simplification. UEFI provocatively subverts the
interface conception of BIOS. Make the operating interface easy-to-use like Windows.
Mouse replaced keyboard as input device, functional modules are the same as Windows
The UEFI has a strong compatibility as well as expansibility. Because it designed a
protective MBR partition. And perfect support for the new GPT partition.
So we said UEFI GPT system is a good combination. More and more Windows 7/8 users
like this combination. However, no matter how good the combination is, it still will
be have problems when using. For example, Windows 7/8 installed on the basis of UEFI
GPT, and its system partition is running out of space, how to resize the UEFI GPT
To resize UEFI GPT system partition with Windows Disk Management, you will face the
problem that the Shrink Volume or Extend Volume grayed
out so that you cannot resize partition through Windows Disk Management. To
resize UEFI GPT partition easily and safely, I recommend you use a third-party
partition software because it is more professional than the Windows built-in one.
Its name is AOMEI Partition Assistant, which is completely supporting UEFI GPT
combination. Let’s free download AOMEI Partition
Assistant Standard Edition first and see how it works.

The second case:
There is no unallocated space exists behind the system partition. You should create
an unallocated space by shrinking the E drive or deleting it first then do as the
AOMEI Partition Assistant can com completely replaces the Windows built-in partition
manager. Its powerful functions include basic partition operations and professional
partition operation. With its help, you can optimize partitions not only save time
but also protect data.
