You will see two options for the USB drive. Microsoft has a dedicated tool that you can use to download the Windows 10 system image (also referred to as ISO) and create your bootable USB drive.

To install as UEFI-GPT you must boot the installation drive as UEFI.ĭuring POST, press F? to launch the boot menu. To install as Legacy-MBR you must boot the installation drive as Legacy Windows can be installed in two ways: Legacy-MBR or UEFI-GPT You can only install as UEFI-GPT on a computer that has UEFI BIOS and using a 64 bits OS Once you deleted all partitions and proceed the drive was converted to MBR. Update: It's weird because I had old partitions with previously installed Windows, but I also shrank an empty partition using Windows Disk Management, and it still wouldn't let me install on this partition, but after I removed all of the partitions including the Windows partitions and formatted them, it allowed me to install Windows with the regular USB created by the Media Creation ToolĪs I explained on post #5, your drive was GPT and you were trying to install as Legacy.
