When Windows 7 is installed, the following error occurs:The user indicates that when Windows 7 is installed, the disk partition interface cannot continue, and the system prompts "Windows cannot be installed on this disk. The selected disk has an MBR partition table. On the EFI system, Windows can only be installed on the GPT disk ." Cause analysis: the boot item is incorrectly selected when you boot and install the system from the CD.Solution: in case

MRB for Win platformGPT is used primarily for Mac (Apple),The relationship between MBR partition table and GPT partition tableGPT disk partitioning style supports a maximum volume of 18 compared to the style of MBR disk partitioning that supports a maximum volume of 2 TB (terabytes) and a maximum of 4 primary partitions per disk (or 3 primary partitions, one extended partition and unlimited logical drives)

The BIOS has self-test and bootstrap program, after the machine power up, the CPU automatically calls the program in the BIOS, the system hardware initialization and hardware failure check, including the various boards. After checking, the BIOS transfers control to the hard drive master boot record (MBR), the BIOS transfer control is very simple, because the MBR on the hard disk fixed track fixed position,

Chen Kozhan===========Typically, our disks are MBR partitioned tables, but MBR disks can only support up to 2T of space, so for more than 2T of space will have to takePartitioning tables with GPT============================================1, hard disk partition: A hard disk can be divided into multiple partitions, each partition is independent of each other, access to each partition is like access to a hard

There are two ways to convert a disk in the form of a disk partition into a GPT partition form for the MBR (Master boot Record), the first from a command prompt that is brought from the system, and the second to use Third-party software, which describes two types of hair: Important: Back up the data on your hard disk before you operate. Command law: Value Description List volume displays a listing of basic and dynamic volumes on all disks. Select

For WIN7/WIN8 that are installed in the MBR partition with a traditional BIOS, you can also use EFI to boot directly into win. First, enter win to extract the EFI boot file, run cmd as Administrator, type the following command BCDboot c:\windows/s x:/F All Copy CodeIn the above command, C stands for the C drive, which is the partition letter of win. s, command parameters, boot to another place. x, the drive letter of a storage boot partition,
