Can Windows be installed on the MBR partition? Can Windows 10 be installed on GPT? Of course you can. Windows 10 uses GPT and MBR disks. Windows 10 can be installed on both MBR and GPT, depending on the computer's firmware. If your computer has the BIOS firmware, you can only install Windows 10 on an MBR disk.
If your computer's firmware is UEFI-based, you can only install Windows 10 on a GPT disc. If your computer has a BIOS-compatible UEFI firmware, you can install Windows 10 on an MBR or GPT disc. If you try to install Windows on a GPT disk on a UEFI-based computer, you will receive the error message Windows cannot be installed on this disk. The selected disk is in the GPT partition style.
Similarly, an error message will appear that says The selected disk has an MBR partition table if you try to install Windows on an MBR disk on a BIOS-based computer. If you have the 64-bit version of Windows 10 (or older versions retired, such as Windows 8.1) and you have a device that uses the Unified Extensible Firmware Interface (UEFI) firmware, you must use the GPT style. However, if you need a system that is more compatible with older hardware, MBR should be the option. Old software that doesn't know GPT interprets only the protected MBR when accessing a GPT disk.
Unlike that of an MBR disk, the MBR protector of a GPT disk performs the function of preventing tools that only support MBR disks from erroneously recognizing and overwriting GPT disks. This MBR protector ensures that old tools don't confuse the GPT drive with an unpartitioned drive or overwrite their GPT data with a new MBR. If a third-party application is used, no data loss occurs during the conversion from GPT to MBR or MBR to GPT. GPT disks automatically back up the main GPT header and partition entries in the last sectors of the disk.
For example, if you prefer a faster boot time, it is recommended to use a GPT disk as the system disk; if the computer is BIOS-based, choose MBR as the system disk; while if you use a disk of less than 2 TB for data storage, both GPT and MBR work well. The GPT header also defines its location on the disk, its GUID, and a 32-bit cyclic redundancy checksum (CRC3) that is used to verify the integrity of the GPT header.
