Out of pure curiosity since I haven't bother with UEFI so far, why doesn't the Ceesum's Disk management screenshot show 3 partitions. I would have thought to see a partition other than EFI called MSR or something similar?

Hello Michael,

The MSR is a reserved partition that does not receive a partition ID, so that's why it doesn't show up in Disk Management. It cannot store user data.

In addition:

Windows and GPT FAQ

Microsoft Reserved Partition

Q. What is a Microsoft Reserved Partition (MSR)?

A. The Microsoft Reserved Partition (MSR) reserves space on each disk drive for subsequent use by operating system software. GPT disks do not allow hidden sectors. Software components that formerly used hidden sectors now allocate portions of the MSR for component-specific partitions. For example, converting a basic disk to a dynamic disk causes the MSR on that disk to be reduced in size and a newly created partition holds the dynamic disk database. The MSR has the Partition GUID:
0x4DB8, 0x81, 0x7D, 0xF9, 0x2D, 0xF0, 0x02, 0x15, 0xAE)

Q. What disks require an MSR?

A. Every GPT disk must contain an MSR. The order of partitions on the disk should be ESP (if any), OEM (if any) and MSR followed by primary data partition(s). It is particularly important that the MSR be created before other primary data partitions.

Q. Who creates the MSR?

A. The MSR must be created when disk-partitioning information is first written to the drive. If the manufacturer partitions the disk, the manufacturer must create the MSR at the same time. If Windows partitions the disk during setup, Windows creates the MSR.

Q. Why must the MSR be created when the disk is first partitioned?

A. After the disk is partitioned, there will be no free space left to create an MSR.

Q. How big is the MSR?

A. When initially created, the size of the MSR depends on the size of the disk drive:
  • On drives less than 16GB in size, the MSR is 32MB
  • On drives greater than or equal two 16GB, the MSR is 128 MB.
As the MSR is divided into other partitions, it becomes smaller.

Windows 7 Professional x64

i want re-instal my laptop.
im using Windows 7 Ultimate x64 and i want change to Windows 7 Professional x64 bit by using UEFI.
when i check what the requirement to using UEFI is :
  • A Windows 7 compatible system
  • A Windows 7 x64-bit installation media. 32-bit is not supported.
  • A UEFI v2.0+ compliant PC. Check your chipset manufacturer/firmware documentation.
  • A blank, partition-free, hard disk for installation
then my question is :

1. How to check my laptop using UEFI v2.0+ compliant PC easily and how to check what are my chipset manufacturer ?
2. Is any problem if i change BIOS to UEFI ?

Well, Asus was about useless for information on your X43U, but here's the download page at Asus to be able download your manual and drivers at.
You have an AMD A50M chipset that is BIOS only, and does not support UEFI.
