I've been playing with Windows 10 on VirtualBox for a while , but the performance on my 2013 13" MacBook Pro Retina is a bit lacking. Since I'd like to get back into playing a few games on this MBP, I decided to take the plunge and install Windows 10 on Bootcamp. I couldn't find any good guides online, so here's a blog post describing in detail what I had to do to get it working.
Go here: http://windows.microsoft.com/en-us/windows/preview-iso
...and follow the instructions to download the ISO. I chose the English (United States) 64-bit (x64) version.
You can continue on while it's downloading. It's 3.8 GB.
Since this process will result in wiping your USB flash drive, make sure you've copied all the info off of there that you don't want to lose. Keep it plugged into your Mac.
Note: I also formatted the drive as exFAT just in case. I'm not sure if this step is necessary or not.
Check both of the active boxes (the middle one should be checked but grayed out).
When your download is finished, select it in the next box.
Allow Boot Camp Assistant to wipe your USB flash drive and it'll copy Windows onto it.
It'll also download more stuff. This took about 10 minutes for me.
Boot Camp Assistant will ask you how much room to add for Windows 10. I'd recommend at least 25 GB. Since I plan to play games on it, I chose 60 GB.
By the way, a good way to free up hard drive space on your MacBook Pro is to move larger files onto a USB drive. I found a 128 GB USB drive with great ratings for $35 which is pretty nuts. That's the size of my old MacBook Air's entire hard drive...here's the link.
While partitioning the drive, I got this error:
The disk cannot be partitioned because some files cannot be moved.
Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.
This will save you a lot of time, so let me put it in unnecessarily loud bolded text:If you follow these steps properly it should NOT require you to reinstall or clone/restore like this recommends.
I got around this by going to Disk Utilities in Recovery mode and repairing the partition.
First, restart in recovery mode by holding Cmd+R while booting up. Select Disk Utilities and do a repair on your main HD partition (NOT the first option in the volume list, usually the second).
Note that you might have to unlock your hard drive to get to the partition Repair Disk. It's on the top toolbar (not pictured above, but you'll see an Unlock icon).
Once the repair is done, restart your Mac normally, log in, and start Boot Camp Assistant again. This time, skip the install disk and download checkboxes.
It will partition properly this time. Whew!
This is a pretty simple process. Boot Camp Assistant will walk you through the process.
It takes a long time, though, like 20 minutes at least I think. Have something else to do in the meantime.
I've always wanted to write that.
Hit me up on Twitter if this helped you! Feel free to let me know any refinements needed. I probably won't be able to provide any tech support though, so figure it out on your own. :)
A few notes after using this for a while:
