Installing Windows 10 next to Mojave on MB Pro Mid 2012 via BootCamp.

Hi,


my MB is listed as supported for such "mission" here.

I followed BC instructions to create bootable WIN10 installation and to partition the drive. After rebooting to start the installation i am prompted with Windows and USB EFI icons. Selecting Windows enters infinitely long black screen. Selecting USB enters Windows installation until formatting part where its not letting me further with the message :


"The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks"


I read multiple texts where it says if i dont follow this route i ll encounter audio problems (which is bad cause i need it). Now the question is, i am being good citizen by following precisely whats described in the link above, but cant move pass the Windows installation.


Any help would be appreciated.

Thanks in advance.

Uros

MacBook Pro

You can use either a DVD+USB2 (for drivers) or USB2 Flash drive for both. If you use a USB3 Flash drive, it will not work.


Can you verify that you are using a USB2 Flash drive (speeds of 480 Mbps or less), instead of a 5Gbps flash drive?


USB drives, other than Flash drives, will cause many other issues.

These are the instructions, just to make sure - Install Windows on your older Mac using Boot Camp - Apple Support.


If you have moment and some patience, please share what the version of USB standard has to do with any of this - i'd be grateful.

The USB2/USB3 ports are identical, unlike USBc. There are separate drivers for USB2 and USB3. You may have a device with the same form factor. Unless you have the correct driver, it cannot be read. USB3 drivers are installed after Windows is installed and BC drivers are installed. Windows installer only has USB2 drivers, not USB3. Does this help clear the picture a bit?

I'll go now and create Bootable USB2 drive and give it another run.

Good. 👍

No, it doesnt really. If i dont Alt to select boot device i get "No bootable device - insert boot disk and press any key". This is MB Pro 13 with DVD. I might have even read an answer from you, that i probably have to do installation from DVD to avoid EFI-like process which in turn causes problems in later stage on this MB.
