Morning all, I'm trying to run Bootcamp with Windows 10 on my 2012 macbook pro (OS X 10.10.5). Normally this would be a remotely easy task, but there's a twist: my disc drive failed me, and instead of replacing it I opted to use an opti-bay for a second hard drive. Since my macbook is still considered a model with a disc drive as far as OS X is concerned, it won't allow me to install Windows 10 from an image file/usb drive/external disc drive (LG brand). I tried using some third party apps on my girlfriend's macbook (same model as mine), and it ended up wiping out her machine (thank god for backups). Does anyone have any tips?
