As suspected, partition output confirms that Windows was installed in UEFI mode and Linux Lite was installed in Legacy/Bios mode. Since computer is only booting into LL right now, the boot mode must be set as CSM/Legacy/Bios (or similar wording). You need to get into the UEFI/(Bios) settings and change the boot mode back to UEFI in order to boot Windows.
Did a quick search for Lenovo laptops and I believe you can get into settings by pressing, holding down, or continuously tapping the <F1> key immediately after powering on computer. Once in UEFI settings, look for a place to change the boot mode. Don't know exactly where you'll find it, so just look through all settings until you find it. Change it to "UEFI". Reboot and it'll boot Windows. Change back to CSM/Legacy/Bios when want to boot into LL -- at least for now, until can convert the LL install to UEFI mode.
As of now, there is no UEFI mode install option for LL. (That's being tested right now for possible release later this year.) Therefore, converting LL to UEFI mode is rather convoluted/tricky. Will need some time to review possible procedure for that and will post back later, or tomorrow. In the meantime, go to Ubuntu and download Ubuntu 14.04.3 LTS (64-bit) and burn that to a dvd/usb. You will need that to convert LL to UEFI mode.
Also, if you haven't already done so, when you boot into Windows turn off the "Fast Startup" feature because that will cause problems with dual booting. http://www.eightforums.com/tutorials/632...s-8-a.html
