No windows after installing Ubuntu

Question

Yesterday I installed Ubuntu, however, after the install had finished there were no bootable operating systems. Neither my Windows 10 or Ubuntu would launch. After reading around I found repair boot, made a live CD, and "fixed" the grub. This allowed me to launch my Ubuntu OS but it still would not let me launch my Windows 10.

This brings me to a few hours ago. Since then I have not been able to fix my system so it launches Win10. I can mount my hard drive that had my Win10 OS on and that was not touched during Ubuntu setup, I have tried the methods here (except manually writing an entry).

I have also tried booting on the HDD that has the partition for Win10 but that provides me with a black screen and a flashing white line. The same result that I had before I ran boot repair and got Ubuntu to work.

So I am asking how can I boot into windows, either by booting onto the hard drive that contains it or adding it to the Grub Ubuntu launches off?

Edit
I forgot to mention my secure boot is disabled so that is not the issue here

Answer 1

It would seem that your Windows was installed in BIOS mode as there is no EFI partition on /dev/sdc but the system is currently in EFI mode per lshw output. You should be able change this setting in your BIOS to either UEFI and Legacy or Legacy and if nothing else is awry the system should boot. The aforementioned discrepency between boot mode and installation mode is very likely what is confusing boot-repair (which you will likely need to run again once your system is booting in the same mode that you installed your operating systems.
