Windows 7
MBP Late 2013 Yosemite 10.10.3 (14D136)
I am getting a Non system disk error when trying to boot from the USB disk that Bootcamp has created. I am using USB 2.0 device.
Any ideas how to get this resolved? Can I install W7 on Yosemite? After all the errors/issues I have gone through, I am thinking there might be some compatibility issues.
MacBook Pro with Retina display, OS X Yosemite (10.10.3), BCA 5.1.4
Was the USB2 created by Bootcamp Assistant?
Hi Loner T! Yes, I used the Bootcamp Assistant to create the USB.
Can you describe how you are trying to boot from the USB?
I run BCA, after it partitions the drive, the machine reboots. I get a non system disk error after that. It says to press any key to continue but nothing happens. I press the power button, then I will get a no bootable device error then.
Can you verify the ISO/DVD used to create the USB with the source from where you obtained it using MD5sum/SHA1 on the Mac side?
You can either openssl md5 command from the OS X Terminal or Microsoft FCIV tool.
I'll check on that, but I was able to use this ISO on a VirtualBox installation previously. I had to uninstall and use bootcamp instead because my application requires the full 4G RAM that my MBP has.
I'll get my hands on the Windows 8.1 trial and see if that works. 😕
On a 15-in late 2013 rMBP, there are two USB ports. Have you tried both?
Can you plug-in the USB, and run
sudo fdisk /dev/diskN where N points to the USB (you can get N from diskutil list output).
Yes, I did try using both. But I mostly use the left one near the power port.
I reformatted the flash drive and am trying to create a boot disk again, so I am not sure if you will get the data you needed. In any case, here it is:
Disk: /dev/disk2 geometry: 7651/255/63 [122915328 sectors]

3: 00 0 0 0 - 0 0 0 [ 0 - 0] unused
4: 00 0 0 0 - 0 0 0 [ 0 - 0] unused
This is not correct. There should be an asterisk in front of the 0x0B to make it bootable for Windows Installer to start.
Can you run the following commands and re-test? Please ignore the i386 MBR message. Please ensure that disk2 corresponds to your USB, because reboot can change order of disks.
sudo fdisk -e /dev/disk2
p
setpid 1
0B
flag 1
p
w
y
Test.
Still the same error.

This is weird. It says the drive is not bootable. I created it from BCA.
This is expected behavior. MBR partitions are not bootable till they are blessed. See man bless in OS X Terminal for reference. Can you power cycle you Mac and hold Option/Alt key? Does the USB show up?
I see, thanks for the info.
The USB does not show up, I waited for a minute only Macintosh HD is available.
Can you rebuild the USB using the first two options in BC Assistant? I will assume that you did not modify the Bootcamp info.plist.
Oops I did modify it . Otherwise BCA won't recognise the ISO as 64 bit (it has both 32-bit and 64-bit versions).
What should have I done instead?
Bootcamp Non System Disk
