I recently upgraded to El Capitan OSX 10.11 and now can't boot into Windows.
If I restart the computer and hold Option down, the only option is OSX. If I use System Preferences to select the bootcamp partition as the startup disk, and then restart without the option key, I get
No bootable device -- insert boot disk and press any key.
I tried booting with VMware Fusion 8.0.1 and got a slightly different response (see image)
From what I've read, I may need to repair the MBR. Here is some investigation I ran sudo gpt -v -r show /dev/disk0
gpt show: /dev/disk0: mediasize=750156374016; sectorsize=512; blocks=1465149168

Some things I have tried without success include
- Using rEFIt. There seems to be a problem running this on El Capitan.
- Using
sudo fdisk -e /dev/disk0. The write command fails withfdisk: /dev/disk0: Operation not permitted. Same result forsudo disk -i /dev/disk0.
My question. How can I make my bootcamp partition bootable again?
