Looks to me the installer failed to install the bootloader, based on the following
messages
...
[ 275.628442] anaconda[1637]: Installing boot loader
[ 275.628541] anaconda[1637]: Running in cmdline mode, no interactive debugging allowed.
[ 275.628640] anaconda[1637]: The exact error message is:
[ 275.628740] anaconda[1637]: 'NoneType' object has no attribute
'short_label'.
[ 275.628839] anaconda[1637]: The installer will now terminate.
Would be useful to see the kickstart used or the full log.
