Install Win10 x64 on MacBook Pro mid 2011 with Boot Camp I have to install Win 10 onto my mid 2011 MacBook Pro (El Capitan) using Boot Camp.

I have two SSD on my machine (one was switched with the SuperDrive) and they works greatly normally.

This morning I woken up and I wanted to install Win 10 onto one of my SSDs. I use yet VirtualBox and tried also Parallel Desktop. But today I want to use Boot Camp.

The situation is:


my Mac doesn't support USB boot to install Win
I have already installed the drivers (via Boot Camp) on a pen drive
I have a beautiful DVD RW (that I burned at least 6 times only today)
I can use the Superdrive externally
I don't know how to burn correctly the Win10.iso


Step 5.: why?

Because Boot Camp doesn't recognize the Win10 DVD (message: "The installer disc could not be found"). I tried many DVD burning formats such as:


HFS+ (okay, this option failed obviously, t's my fault: it's an Apple format)
DVD UTF
PC (Joliet)
ISO9660
Joliet 103 characters (solo)


using Burn.

I tried also to burn the ISO via El Capitan's Disk Utility. Same error.

The destination disk is correctly formatted Ex FAT Master Boot Record.

I don't know to do.



UPDATE



I noticed that the error message The installer disc could not be found was referring to the USB Boot Camp Drivers.

So, it was not a DVD problem. I didn't plug the USB drive with the drivers. My fault. Now I plugged both Superdrive and the USB with the drivers. 

Finally Boot Camp Assistant now is happy and left me to continue. After click Continue the Mac rebooted automatically, but... I seen a black screen with a intermittent underscore at top left of the screen (this is a little good sign: it was the Windows boot).

But the BIOS (?) seems to be locked, no messages, no alert, nothing... only this intermittent underscore. I waited 15 - 20 minutes and nothing changed. I tried to press Enter, Space without any result. So I have to reboot the machine.

From the Mac OS X partition I can see:



So I think the DVD results bootable.

What could be the problem now? :(
The correct way to burn the Windows iso file to a DVD using El Capitan would be to do the following.


Find the iso file in the Finder.
Right click on the file and select Burn Disk Image "File name" to
Disc....
Follow the instructions given in the pop up window.


If the Boot Camp Assistant application will not recognize the external DVD drive, then you can try the following.


Insert the burned DVD in the external DVD drive.
Restart type Mac and hold down the option key.
See if the DVD icon appears with the label "Windows" in the Startup
Manager.
Select the icon and see if you can boot from the DVD.


If you can boot from the DVD, you probably can use the external DVD drive to install Windows. First, you will need to create a MSDOS (FAT) formatted partition to install Window on to. This usually is the 4th partition on the drive.

If you can not boot from the external DVD drive, the one possible option would be to install directly from the Windows iso file. See web sites here and here for some examples of how to do this.

By the way, how did you acquire the Boot Camp Support Software? Did you use the Boot Camp Assistant to download or did you download from a web site?
