Why Do You Want to Change MBR to GPT in BIOS on Windows 11
In most situations, a regular user will have no reason to change MBR to GPT in BIOS, especially if they are using an older OS. However, this can be an essential improvement to Windows 11 performance.
Here we will give you some of the most common situations that require you to convert MBR to GPT in BIOS. If you ever encounter one of these issues, this guide contains tried and proven solutions.
- Windows 11 OS disk was converted to GPT by mistake and isn't bootable now.
Due to Microsoft's updates in Windows 11, it now requires UEFI and Secure Boot to install.
Unfortunately, users need more skill to make sure their PC is booting correctly. The fundamental problem is when the OS disk is converted to GPT while remaining on MBR in BIOS.
Since changing the Disk partition type will likely require formatting it, you are better off just changing the BIOS settings, as this will allow your PC to BOOT.
- UEFI boot mode and secure boot mode were disabled on Windows 11 as the OS disk is with MBR.
Windows 11 requires UEFI and secure boot mode to be installed and run, and an MBR type partition does not support those settings and protocols as it hails from an older era.
As a result, your Windows 11 partition will need to be changed to GPT to enable these settings.
- Windows 11 was disabled on dual boot OS, and Windows 10 is currently used.
Sometimes, people will want to dual boot Windows 10 and Windows 11. This is most commonly the case with programmers, but it can also be done to increase the optimization of some programs that haven't been updated for Windows 11.
Since Windows 10 doesn't require GPT as 11 does, people will decide to run their Disk on MBR more often than not.
This can cause issues when you decide to enable Windows 11, so changing the Disk to GPT in BIOS is necessary.
Users want to change the MBR disk to GPT on the computer without OS.
To install Windows 11, you will need a GPT partitioned disk. If you first install this operating system and partition the disk in the MBR system, this can be an issue.
To make Windows 11 usable on that disk, you must first change it to GPT in BIOS.
