When installing the system, the disk adopts the GPT partition format to convert the MRP format.

When installing the system, the disk adopts the GPT partition format to convert the MRP format.
When installing the system, the system prompts: windows cannot be installed on this disk. The selected disk adopts the GPT partition format.
Problem: windows cannot be installed on this disk when a windows 7 or win8 system is prompted for the installation of the notebook disc. The selected disk adopts the GPT partition format. (The primary partition is used after the PE mode of the optical disk. After the Ghost is copied, the system cannot be started because 0 * c000000e is unavailable during restart .)


Analysis: Because the partition table of this hard disk uses GPT partitions, It is a disk partition architecture used by the extended firmware interface (EFI) in the Itanium computer.
Disk needs to be initialized, MBR partitioning (reformatting is not a solution). Or UEFI boot GPT Installation
Solution:
1. MBR partitioning
Tip:
1. F2 enters BOIS to set the disc to start
2. There is no data in the entire partition. Remember to back up the data on the disc or USB flash disk in PE mode before performing this operation!
On the select partition page, press SHIFT + F10 to bring up the cmd Command Prompt:

Enter the following parameters in sequence:
★Open the diskpart Tool
Diskpart, press ENTER
(Listdisk -------------------- list the disks owned by the system, which can be omitted)
★Select target disk
Select disk 0 press ENTER -------------- select disk 0. select the target disk based on the disk size.

★Clear the target disk and convert it to mbr format
Clean press ENTER ----------------------- to clear the disk. This command will erase all data on the disk.
Convertmbr press ENTER ---------------- convert the disk to MBR format
(Convert gpt ---------------- convert the disk to GPT format)
In this way, the GPT partition is converted to MBR. After the conversion, you need to re-partition the partition and then install it.
Listpartition ----------------- list partitions on the disk. The partition is empty because the partition is just converted to the GPT format)
★Create an EFI partition and system installation partition (create a new partition and use it to enter the PE partition)
(Create partition efisize = 100 --------------- create an EFI partition with a size of 100 M. If you want to use this partition to guide the MAC system, we recommend that you create partition msr size = 128 -------------- create an MSR partition larger than M, if it is set up by Microsoft by default, the size is 128 M) createpartition primary size = 50000 press ENTER ---- create a primary partition, the size is 50000 M, please adjust according to your needs, this partition is used to install win7 or win8.
List partition press ENTER --------------------------- list partitions on the disk format fs = ntfs quick press ENTER ---------------------- partition format on the disk is NTFS
Exit press ENTER ------------- to exit
Exit press ENTER -------------- to exit
Note:
· In fact, a diskpart tool can almost replace other third-party disk tools. For example, the famous DiskGenius tool cannot change the disk partition ID in GPT format, but diskpart can.
· When installing the MAC system, you need to change the partition ID.
· For detailed use of diskpart, you can enter help in diskpart to view
2. Complete installation
On the partition selection page of the windows Installer, click "refresh" to list the partitions created above, select the corresponding partition, select next, and continue the installation.
