Your new installs in sda are BIOS boot with MBR(msdos) partitioning.
But your install in sdb is UEFI.
So you booted Boot-Repair in UEFI mode and it converted the Ubuntu install in sda, to UEFI booting from the efi partition in sdb. It now has the efi partition refered to in fstab.

If you boot Boot-Repair in BIOS mode, uninstall grub-efi and install grub-pc and install grub2's boot loader to the MBR of sda, it should work.
You also show a grub installed to the PBR or partition boot sector of sda1. That will not boot anything, but is otherwise unused space so not an issue if grub is correctly installed to MBR of sda.
