Apologies in advance of yet another request for help in building a Windows Bootcamp on a Mac. I like to think after 20 odd years servicing, supporting and managing computer environments I would get this sort of thing...but in this case I don't I have a iMac i7 (Oct 2013) Mavericks USB 3.0 Flash drives USB 2.0 external 500Gb HDD Windows 7 ISO image external USB 2.0 Samsung BluRay drive BootCamp 5.1.2 I've read multiple posts and forums about how to create a W7 Bootcamp. perhaps thats the problem...too many seemingly conflicting bits of information But nothing I try seems to work. I can create a BC partition but installing Windows either just doesn't work or just gives me a Boot device not found if I use a flash or DVD. Any pointers in simple language please on the best way to go about this ?
