UEFI Boot Windows boot (3)

Currently, UEFI-enabled Windows has Windows Vista 64-bit, Windows7 64-bit, WINDOWS8 32/64-bit, and Windows Server 2012. Now take Windows 7 as an example of how to start in a UEFI environment, just for a basic level of introduction.

    UEFI boot Windows must have a FAT partition (often called an "EFI system Partition") that has files that boot windows in this partition. Automatically find the under the FAT partition after booting Span style= "font-size:large;font-family: ' italics ';" > file, and then find the

Bootmgfw.efi file We can also run it manually under the EFI SHELL. In addition, "Efi\boot\bootia32.efi" or "Efi\boot\bootx64.efi", which manually runs the FAT partition under the EFI SHELL , can also enter Windows. In the UEFI BIOS we can also set the EFI file as the startup item, the default startup item.

the above Bootia32.efi, Bootx64.efi are 32-bit, 64-bit UEFI boot Windows required files. The one by one corresponds so that 32-bit systems cannot be installed in a 64-bit UEFI environment.

one of the conditions described above for UEFI to start Windows is: FAT partition exists related file . Does not say that a GPT disk is required, usually the "uefi+gpt" is associated with an important reason is that the "UEFI+MBR" Environment using the Windows original CD installation will be prompted: EFI-based system can only be installed on the GPT disk (Microsoft Restrictions)!

Many motherboards are now able to switch between "UEFI bios" and "Legacy bios", so the "uefi+mbr" solution: Switch to the Legacy BIOS first, After installing the system, switch to the UEFI BIOS, create a new FAT partition yourself and copy the relevant files to this partition (also available with the BCDboot Command line tool). Solution Two: Enter PE (UEFI enabled), install Windows to the hard disk, and then Create a new FAT partition yourself and copy the relevant files to this partition (You can also use the BCDboot command-line tool).
