[SOLVED] Error installing along side Windows 10

[stevef]

Can you tell us a bit more about your system ?
The manufacturer and model and the type and version of the UEFI/BIOS software - usually displayed fairly prominently on the set up screen.  Knowing this might help us understand what you are seeing.

I was able to mount and get to the Windows 10 partition

That's good.  Before, it gave the 'wrong fs type' message when trying to mount the W10 partition from Linux Lite.
What did you do differently to mount it so that you could access it?

I didn't see any sign of Windows 10 anywhere in the BIOS.

The UEFI/BIOS may not reference W10 directly.  Different UEFI/BIOS use different wording.
Any options called something like 'Boot Manager' or 'OS Manager' might be useful.

What should I try next to try and get Windows 10 to boot?

1) Some systems may display a brief message while booting suggesting to press a key to access a 'Boot Manager'.  Look out for anything like that and try it.
2) Assuming your system is UEFI, turn the system off and then power up while holding the right hand shift key down.
This may force the system to show a bootloader menu.
