Install Windows 7 in Mid-2015 Macbook Pro

Good Afternoon All,

I am trying to install Windows 7 onto a Macbook Pro that bootcamp no longer supports putting Windows 7 onto. I have a Product Key for 7 and want to upgrade to Windows 10 but, unfortunately, Windows 7 has to be on the machine first. I used a friends Macbook Pro early 2011 to create a WININSTALL USB stick using their Bootcamp software (which permits Windows 7 because of his 2011 model) but when I reboot and hold the OPTION key it does not even recognize the stick. The only thing that is there is my Mac HD. Does anyone know of a method to get Windows 7 onto one of the new Macbook Pro's? I have moderate computer skills and can do some things in command line, use Xcode to modify files like bootcamps .plist, etc.

Thank you for your suggestions,

MacBook Pro (Retina, 15-inch, Mid 2015), OS X Yosemite (10.10.5)

Hello felipeqga,

I suppose you were responding to me and I don't understand your reply: my problem isn't to install windows 7 on my external drive (USB/SSD), but to boot on it on macbook startup (alt). I manage to see it as a EFI boot, but then I get a black screen.

Is what you wrote: the problem is the booting of windows 7 on an external USB3 drive ?

Thanks for the answer,

Elric

Thanks.

Like I wrote before I have:

- an externalisation hardrive (SSD) in an USB 3 case

- a MacBook air 2015

- an ISO and à DVD windows 7 pro

- an old MacBook 2009 with a bootcamp partition on the internal hardrive

- I successfully installation windows 7 on the externalisation drive or clone my Old windows 7 bootcamp partition

- I see the externalisation drive on holding alt as à ''EFI boot''

- the MacBook (2009 and 2015) won't boot correctly (black screen or rebooting on internal osx) on the external drive

- I've tried many méthodes

- I just tried to put the inf and sys usb3 drivers directly in the windows directories... But i still doesn't boot

I'm aware I 'try something no so easy. Combining the windows 7 problématique with usb3, plus à boot on an externalisation usb drive, plus doingbthis on a MacBook 2015 so it have to be a ''EFI boot'', so I must installation windows 7 64 bits kn EFI boot mode, and on and on... But I think there must bé à way tonget this to work: boot windows 7 64 bits on an externalisation usb3 drive on a MacBook air 2015 ! ;-)

Great,

Do you trying to Boot Windows via USB?

Friend, already read various documentation and never saw anyone start Windows via USB. You can install Windows via USB but can not run the Windows system via USB.
