Are you using GRUB?
If not I'd install GRUB to /dev/sda

Welcome to the forums.
With UEFI you do not install grub to the MBR. You actually have the new gpt partitioning not the very old MBR(msdos) partitioning.
The default boot entries that grub2's os-prober creates do not work. They are the BIOS type entries and you have to have an efi type entry.
Boot-Repair added new entries and those should chain to the Windows efi partition.
Have you turned fast boot off? That often causes issues.
Can you boot Windows directly from UEFI menu.
It looks like with your UEFI menu you have many options. You have 19 or Ubuntu set as first and 18 or Windows as second.

How did you shrink Windows? Did you use Windows MMC to shrink itself. And reboot so it runs chkdsk? Not sure which of the boot choices for rescue or repair are the standard Windows. Do not run the Lenovo repair as that will probably restore system to as purchased.
