So why is your Mac showing this error? “This disk doesn’t use the GUID partition scheme” I know from experience how confusing these kinds of messages can be when all you want to do is install MacOS on a MacBook.
When you try to install macOS on your MacBook, if the drive uses MBR (Master Boot Record) partitioning instead of GUID, then you will get this error message about GUID.
The GUID (Globally Unique Identifiers) is the partition scheme used for EFI/UEFI-based systems like newer Macs. In general, it means you have to reformat the disk to use the GUID partition table before you can install it.
