14.04 - No windows after installing Ubuntu - Ask Ubuntu

yesterday installed ubuntu, however, after install had finished there no bootable operating systems. neither windows 10 or ubuntu launch. after reading around found repair boot, made live cd, , "fixed" grub. allowed me launch ubuntu os still not let me launch windows 10.

this brings me few hours ago. since have not been able fix system launches win10. can mount hard drive had win10 os on , not touched during ubuntu setup, have tried methods here (except manually writing entry).

i have tried booting on hdd has partition win10 provides me black screen , flashing white line. same result had before ran boot repair , got ubuntu work.

so asking how can boot windows, either booting onto hard drive contains or adding grub ubuntu launches off?

edit
i forgot mention secure boot disabled not issue here

it seem windows installed in bios mode there no efi partition on /dev/sdc system in efi mode per lshw output. should able change setting in bios either uefi , legacy or legacy , if nothing else awry system should boot. aforementioned discrepency between boot mode , installation mode confusing boot-repair (which need run again once system booting in same mode installed operating systems.
