Your disk sda has an msdos partition table, so Windows is installed in bios mode. You are trying to install Ubuntu in uefi mode which won't work here - you have to have the same installation type (bios) as Windows.
To do that the installer has to be booted in bios mode.

It looks like even though you booted Boot-Repair in UEFI mode, that is is offering to reinstall the BIOS boot version of grub or grub-pc.
Since you have a new UEFI system, but have Windows in the 35 year old BIOS/MBR configuration, you need to always boot in BIOS mode.
