Start mode must be UEFI + GPT or Legacy + MBR combination, or can not install the system properly, Legacy + MBR mode of computer support the installation of any Windows system without any modification, can be installed directly from the high-low version of the system version. UEFI + GPT mode supports 32 mounted win8 / win8.1 and win10,64 bit win7, win8 / win8.1 and win10, that is mounted or ghost win10 win10 partition table is not modified format.
mbr format is also available. Do not set UEFI boot on the line when you start. Now most new motherboards support the new UEFI BIOS, in this case, can only install 64-bit systems, and can only be installed on a GPT disk. If you want to use the traditional MBR disk mode, must go to the motherboard BIOS, UEFI BIOS will support instead of traditional BIOS (Legacy BIOS).
GUID Partition Table (GPT) was introduced as part of the Extensible Firmware Interface (EFI) program. PC commonly used older Master Boot Record (MBR) partitioning scheme with respect, GPT provides a more flexible disk partitioning scheme.
Partition is a storage space on a physical or logical disk connected to each other, just like the physical disk as an independent work. For the system firmware and the installed operating system, the partition is visible. Before the operating system starts, access to the partitions controlled by the system firmware, after the operating system is started by the operating system.
GPT disks can achieve tremendous capacity. The number of partitions on the disk is not limited GPT provisional program (such as MBR Extended Boot Record (EBR) defined by the container partitions). GPT disk partition-defined and fully automatic recognition. The key data is placed in the operation of the platform instead of partitions or unpartitioned "hidden" sectors. GPT disks use the original, the partition table and CRC32 field store redundant backup to improve the integrity of the partition data structure. GPT partition format uses version number and capacity of the field to support further expansion.
Each GPT partition has a unique identification GUID and a partition content type, so no coordination to prevent partition identifier collision. Each GPT partition has a 36-character Unicode name. This means that any software can present a human-readable name of the partition, without understanding the other contents of the partition.
win8 and win10 system defaults is to use UEFI boot, the hard disk partition table to GPT, in order to achieve quick start, and the system prior to win7 adopt Legacy boot and MBR partition table, if win7 upgrade to win10 need to change the hard disk partition format it? In fact, this requires hard disk partition table to determine the type of motherboard according to the startup mode.
1, first check the motherboard supports UEFI boot, boot press delete to enter the bios, the OS Optimized Defaults is set to Enable (if this one).
2, to set the Secure Boot Enable, UEFI Boot / Boot Mode select UEFI or Enabled is Enable, CSM is provided, according to F10 to save.
3, and then enters the u-PE system cabbage, modify the partition table of GPT to MBR format.
These are the ways to install win10 systems change the hard disk partition format, if your computer is to install a new machine or win10 win8 when you need to change the hard disk partition table type to fit the motherboard startup mode.
