Your computer's boot drive has what is called a "partitioning style." If you want to upgrade to Windows 11, your drive must use the GPT partitioning style. This video will show you how to convert your drive from the MBR partitioning style to GPT partitioning so your computer can qualify for Windows 11 (there are other requirements your computer must meet in addition). 0:00 Convert Boot Drive from MBR to GPT Partitioning so You Can Upgrade to Windows 11 0:38 Why is this necessary? 1:08 Check your computer for Windows 11 compatibility 2:04 BIOS - what is it? 3:18 How to verify what BIOS mode my computer is using 3:47 GPT partitioning required for UEFI mode 4:52 Two stage problem prevents upgrade to Windows 11 5:31 How to determine what partitioning style my drive uses 6:45 Warning to backup drive before making changes 8:34 How to access BIOS 9:15 Understanding why UEFI mode is not compatible with MBR 12:40 How to find your drive's model ID/name 13:11 CONVERSION METHOD #1 - MBR2GPT 14:04 How to access Windows Recovery Environment (Windows RE) 16:16 Doing the MBR2GPT conversion 18:18 Entering BIOS, changing Boot Mode to UEFI 19:31 Rebooting into Windows, conversion successful! 20:00 Confirming partition style is changed to GPT 20:40 Confirming BIOS mode is changed to UEFI 20:54 Re-running PC Health Check to see if I can upgrade to Windows 11 21:14 CONVERSION METHOD #2 - Minitool Partition Wizard 25:59 Conversion completed, but must update BIOS boot mode 27:59 Second conversion successful! 28:19 Confirming partition style is changed to GPT 28:55 Confirming BIOS mode is changed to UEFI How to Clone a Drive: How to Build a PC: Disclosure: This post may contain affiliate links, meaning I get a commission if you make a purchase through my links.

If any of these checks fails, the conversion will not continue. When typing the MBR2GPT command, if no disk or drive is specified, the program assumes you are acting on the boot drive (usually drive C:). For additional options and syntax, check the link above.
