Windows Setup: Installing using the GPT or MBR partition style

Many PCs now include the ability to use the UEFI version of BIOS, which can speed up boot and shutdown times and can provide additional security advantages. To boot your PC in UEFI mode, you'll need to use a drive formatted using the GPT drive format.

Many PCs are ready to use UEFI, but include a compatibility support module (CSM) that is set up to use the legacy version of BIOS. This version of BIOS was developed in the 1970s and provides compatibility to a variety of older equipment and network configurations, and requires a drive that uses the MBR drive format.

However, the basic MBR drive format does not support drives over 4TB. It's also difficult to set up more than four partitions. The GPT drive format lets you set up drives that are larger than 4 terabytes (TB), and lets you easily set up as many partitions as you need.

Boot to UEFI mode or Legacy BIOS mode

Boot into UEFI mode or legacy BIOS-compatibility mode when installing Windows from your USB, DVD, or network location.

If you install Windows using the wrong mode, you won’t be able to use the features of that firmware mode without reformatting the drive.

Select the firmware mode during bootup.

1. Boot the PC. As the firmware starts to run, press the key that opens the boot device menu. For example, press the Esc, F2, F8, F9, F12, or other key to enter the firmware or boot menus.

2. On the boot device menu, select the command that identifies both the firmware mode and the device. For example, select UEFI USB Drive or Network - BIOS.

Note   Note
You might see separate commands for the same device. For example, you might see UEFI USB Drive and BIOS USB Drive. Each command uses the same device and media, but boots the PC in a different firmware mode.
Here is an example of the one-time boot menu.

If your Windows 7 USB flash drive is formatted as FAT32 file system, then it should be bootable in UEFI mode. When you boot from the USB flash drive, UEFI mode starts the boot process either from the "\efi\boot\bootx64.efi" file or from the "\efi\boot\bootia32.efi" file. There are only a few computer systems that have the 32-bit UEFI firmware and in that case you must use a 32-bit version of the Windows 7 USB flash drive.

64-bit UEFI firmware:
As long as the USB flash drive is FAT32 formatted and has \efi\boot\bootx64.efi file, it should be bootable in UEFI mode.

32-bit UEFI firmware:
As long as the USB flash drive is FAT32 formatted and has \efi\boot\bootia32.efi file, it should be bootable in UEFI mode.

The \efi\boot\bootx64.efi or \efi\boot\bootia32.efi file does not exist by default in the Windows 7 installation media, so you need to create this file by using the Rufus program, if you want to install Windows 7 in UEFI mode. Rufus automatically creates the boot folder in the efi folder and puts the bootx64.efi or bootia32.efi in the folder, when you create a Windows 7 USB flash drive.

Rufus - Create bootable USB drives the easy way

If you want to install Windows 7 in UEFI mode, then select the following settings.

Under Partition scheme and target system type, select GPT partition scheme for UEFI.
Under File system, select FAT32.

If you want to install Windows 7 in Legacy BIOS mode, then select the following settings.

Under Partition scheme and target system type, select MBR partition scheme for BIOS or UEFI-CSM.
Under File system, select NTFS.
