Hi Gordon
Thanks for your help.  unfortunately it is still complaining.
Currently, I try to install and it fails, I remove all the partitions from
ALT-F3 console using wipefs, check with parted -l that the partitions and
labels are wiped and then reboot.

It fails again with:-

ERR ananconda: Bootloader setup failed: failed to find a suitable stage1
device
INFO anaconda: fs space: 0 B needed: 2861.02 MiB

If I reboot, select legacy BIOS it works

The only differences in the Kickstart files are as follows:

legacy KS
bootloader --location=mbr --boot-drive=sda --driveorder=sda,sdb
 --append="console=tty0 console=ttyS1,9600 console=ttyS2,115200"
clearpart --all --initlabel

---  UEFi Ks below:
bootloader --location=partition --boot-drive=sda --driveorder=sda,sdb
--append="console=tty0 console=ttyS1,9600 console=ttyS2,115200"
clearpart --all --initlabel --drives=sda,sdb
part /boot/efi --fstype="efi" --size=200 --ondisk=sda

And I have tried the latter with location as mbr still fails

What am I missing ?

Thanks
