Hey guys, a friend and I installed a second hard drive into his 2011 Macbook Pro and now we're trying to install Windows 8.1 onto it with a bootable USB. We've tried using bootcamp, but for some reason the "Create Windows 7 or later install disk" option is not showing up. We took out the optical drive as well, so we can't use a CD. I've also tried making a boot usb on my PC, but the mac will not recognize it as a bootable device when starting up. Is there any other way we can accomplish this?
Here's the instructions:
Mount the second hard drive to a Windows VM. You must have a Windows VM in VMware/Parallels.
What you need:
install.wim file (obtain this from your Windows ISO)
Open elevated cmd.exe
Note: All commands aren't case sensitive, including pathway to files.
Type diskpart
Type list disk
Take note of the disk you want to select
Type select disk 1 (if your disk is Disk 1)
Type clean
Type convert gpt
Type create partition EFI size=100
Type format quick fs=fat32 label=EFI
Type assign letter=S
Type create partition primary
Type format fs=ntfs quick label=W2G (or any other name you wish for label)
Type assign letter=E
Type exit
Open up File Explorer. In your C drive, create a new folder named WIN2GO.
Put the install.wim file in this folder
Back in cmd.exe:
Type dism /apply-image /imagefile:C:\WIN2GO\install.wim /index:1 /applydir:E:\ (this process will take quite a while)
Type E:\Windows\System32\bcdboot E:\Windows /s S: /f UEFI
Restart your entire Mac. After the chime, hold down Option and when prompted to select your boot drive, select EFI Boot.
Proceed installation normally.
After installation, install Boot Camp drivers.
This method worked for me when I installed Windows 8.1 UEFI into a drive in a USB 3.0 enclosure (UASP-supported). It should work on your friend's MBP too.
