revert Posted April 24, 2017 Share Posted April 24, 2017 I've been dual booting Yosemite with Windows 7 for a while and decided to update to Windows 10. I use a chameleon bootloader. After updating, even after multiple reboots, I had no issues loading Windows 10. Then I shut down and loaded Yosemite the next morning. Now, whenever I try to load Windows, it crashes with the error inaccessible boot device. I tried booting with a Clover USB bootloader. It worked fine for Yosemite but the same issue with Windows. Does anyone know the cause and any potential fixes? Thanks in advance.

revert Posted April 24, 2017 Author Share Posted April 24, 2017 Thanks for the link. I already have both installed and been that way for a couple of years. My motherboard has no UEFI boot options unfortunately so I'm stuck for now.
