Improve installation of bootloader

This is old problem, but during installation some bootloader installation fails, i would prefer to have some sort better ui experience for grub installation.
like after installation another script should be run step by stem bootloader installation.

I think the best aproach right after install script done , start bootloader script installation:
It would ask in terminal:
Hello are you have modern hardware UEFI supported? YES NO
If YES , it install grub2 for UEFI
If No , it says ok back to start
Then again user asked , but this time user should see Do you want to install booloader on old hardware ? YES NO
If user selects YES, if check it asked for partition in format like /dev/sdax , then grub2 for old hardware should be installed if NO selected program exist with a message please prepare your partitions for grub installation
