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
