Boot Loader Install Failed

I am trying to install Clearos 7.2 on two different systems and install keeps failing with the message: "boot loader install failed" on both of them. The message details read as shown below.
anaconda 21.48.22.56-1 exception report

I tried turning off UEFI boot in the BIOS. I tried allowing only UEFI boot in the bios.

I tried automatic partitioning for UEFI boot or legacy boot installs.

For the legacy boot I tried manual partitioning with
BIOSBOOT - 1 MiB or 2 MiB
/boot - 500 MiB
/ - 100 GiB
/home 360 GiB
SWAP - 8 GiB

For UEFI boot I tried manual partitioning with
/boot/efi - 200 MiB
/boot - 500 MiB
/ - 100 GiB
/home 360 GiB
SWAP - 8 GiB

I tried the ISO that supposedly has fixed up code in it that was linked in another message.

I always get the same message.

PFsense 2.3.2 will install on either system without any difficulty, but I want to install Clearos 7.2.

Any idea how to fix?
