I have a Lenovo Twist with two HD. Win8.1 is installed on sda and Kali is on sdb. Grub is installed with Kali on sdb. When I boot to sdb Grub loads fine and "sees" the Win8 disk (listed as Windows 8 loader). When I choose Win8 it fails to load --> I get Windows Boot Manager error " failed to start; the boot configuration is missing".
If I boot to sda Windows loads without issue.
My goal is to set primary boot to sdb and use Grub to choose where to go .. (duh..!).
Any ideas?
Thank you.
