I have tried many times, but installation continues to fail. After tuning the installation application with errors, a reboot ends with "no bootable device". I have tried with both UEFI and Legacy boot in the BIOS. I have the EFI System Partition (ESP) as "/dev/sda1" and "/dev/sda2" available for the installation.
After installation using LVM (no encryption), the system says complete and restart. I remove the USB flash drive; then the PC cannot find a bootable device.
