Hello! Today I tried to set up Boot Camp for the first time, and I'm having issues. Where I am with it: I have the Windows 10 Preview iso downloaded. I have the Windows Support Drivers downloaded, on a USB stick. I have a 4.7GB DVD-RW disc to burn the iso onto. I am using an iMac 21.5" Mid-2011 (has SuperDrive). I am using Yosemite (latest version). It's at this point that I get lost. All instructions I see online point to an option in Boot Camp Assistant that I do not have (create a boot disc). I've tried to burn the iso onto the DVD-RW disc, but I get an error in the Assistant stating: The installer disc could not be found. Insert your Windows installer disc and wait a few seconds for the disc to be recognized. I'm starting to get a tad frustrated. Anyone know the solution?
