    Ever since I first tried to install Windows I have had problem after problem. The first problem was actually installing Windows to a MBR/GPT drive thingy. I got round that and managed to install Windows but had no sound drivers. (Windows 10/Windows 8.1) Tried everything to get sound working but gave up and wiped my partition. Now I am trying to install Windows again but without Boot Camp this time (I have a superdrive so I can't do it with USB - I changed my info.plist and Boot Camp just kept crashing - I know there is a terminal command but that didn't work and it still continues to crash so I changed my info.plist to the original setting). This time I have got my Windows 7 USB from Microsoft, put it on a Windows PC, downloaded "Windows 7 USB DVD Download Tool" from the Microsoft website, successfully created a bootable USB. Plugged it into my MacBook and booted up the boot menu but one problem was that the USB didn't show up. (I think maybe because it's now NTFS format) so I downloaded rEFInd and installed it, restarted my MacBook and pressed Option+CMD and rEFInd boot menu showed up, I clicked Boot Windows NTFS partition and now it says "No Bootable Device --..."

    Please someone tell me why I am finding it so difficult just to have a nice copy of Windows installed with working audio. If you need any more information please ask.

    You can't install Windows in UEFI mode, if that's what you tried. UEFI mode will cause all sorts of problems on pre-Haswell Macs, like graphics and audio issues.

    You have to just use Boot Camp assistant for everything and let it do the formatting/partitioning for you.
