Am having the same issue (dual boot, win10 and linux mint based on ubuntu 14.04). Linux boots, but not win10.
Looks like bug was introduced with 2.02~beta2-9ubuntu1.7.diff.gz Check here for the commit details: http://launchpadlibrarian.net/230268356/grub2_2.02~beta2-9ubuntu1.6_2.02~beta2-9ubuntu1.7.diff.gz Maybe the author of the affected 1.7 version (dann frazier) can help us - I added his e-mail to the subscriber list of this bug.
