Here I read this in the manual for the PC.
A certain percentage of users may choose to re-install the 64-bit OS with a
Microsoft DVD. On machines with UEFI BIOS, the DVD setup utility may try to install
the image in GPT format by default. If this is not what the user wants, then the DVD
setup utility will need to be manually selected to install in MBR format instead. To
install in MBR mode, the user will need to access the boot menu using F9, then
select “Legacy Boot Sources/ATAPI DVD Drive/SATA0” as shown in Figure 5.
