How to adjust the UEFI mode after installing WIN8

Each WIN8 system has a boot mode, either in BIOS mode or WIN8 UEFI. This is already confirmed after the installation of Win8. But as long as mastered the method, the original BIOS boot WIN8 system can also be changed to UEFI system, together to see:

　　Win8 the method of adjusting the UEFI mode after installation

1, first of all, we first install a good Ghost Win8 system, here we have installed;

2, then we have to go to the motherboard BIOS to set the boot mode for UEFI, here is not detailed on each motherboard setup steps are different, but the key UEFI open all the same. The hard drive has been unable to boot, then use a support UEFI boot PE into the PE system (the latest computer stores, cabbage, old peaches are supported)

3, enter the PE, format the boot partition (is a 100MB or 350MB small partition.) If not, do not format, on the hard drive to find a way to separate a 100MB FAT32 partition), note that you must select the FAT32 file system.

4, change the label, easy to identify (can skip)

5. When the format is complete, open a command prompt and type the command: BCDboot d:windows/s C:/L zh-cn/f All

This allows you to repair the EFI boot partition. In fact, this also fixes the BIOS boot, if back to the BIOS boot, or can boot successful, this step is to copy the boot to the 100M hidden boot partition.

Note: The above code D is the system file partition (that is, Windows, program files, and other folders in the partition), C is the FAT32 partition, according to their actual situation to enter the appropriate letter, otherwise it will be wrong.

The boot partition has been successfully repaired.

You can see that the boot file has been repaired.

Look at the BCD, it's good.

Reboot, it's ready to boot.

The above is the installation of Win8 after how to adjust to the UEFI mode of the introduction of the method, set up later to see the Win8 startup way, you will find has become uefi.

Editorial Reviews: Why change to UEFI mode?

　　What are the six main advantages of UEFI:

1, UEFI to provide a larger disk capacity

Traditional MBR partitions can support only 2.2TB hard disks and 4 primary partitions, and one of the UEFI specifications, GPT partitioning format, can support hundreds of terabytes of hard drives and 100 primary partitions, especially useful for users who use Win7. On the other hand, in Asus, Gigabyte and Seagate, such as the efforts of manufacturers, 32-bit system + traditional MBR partition can be "virtual disk", such as the use of the form of more than 2TB hard drive, but that is certainly not as good as the original UEFI+GPT support labor saving worry.

　2, UEFI to provide a higher performance

Traditional BIOS is designed for traditional 16-bit processors, with low addressing and poor performance, while UEFI can be applied to any 64-bit processor, with a lot of addressing capabilities and performance excellence--simply by loading more hardware and faster booting to Windows.

　　3, 64-bit new system has advantages

Starting with Windows Vista SP1 and Windows Server 2003, as long as 64-bit systems can provide UEFI boot support, XP systems, 32-bit new systems can only be powered up via UEFI compatible modules.

　　4 , more convenient bulk installation

Motherboards equipped with UEFI can be "broadcast" installed over the network, with 1 mirrored broadcasts to install the operating system on multiple machines, which is especially convenient for enterprise users.

5, faster boot, hibernation recovery

The traditional BIOS uses an INT 13 interrupt read disk, only read 64KB each time, very inefficient, while UEFI can read 1MB each time, load faster. In addition, Microsoft's next-generation operating system WIN8, but also further optimize the UEFI support, is said to be able to achieve instantaneous boot.

6. More Secure Startup

Previously, Win8 used UEFI to limit the survival of systems such as Linux, essentially designed to prevent users from running unauthorized code to ensure better security, and users can choose to turn off this feature if they feel they don't need it.
