I have installed Zorin 18.1 Core on my HP EliteBook 840 G2 and when it restarts I get the no bootable image message.
BIOS is set to UEFI Native (without CSM) with secure boot turned on. I have set the define customised boot option to \EFI\ubuntu\shimx64.efi and still it won't boot.
I've tried installing without secure boot turned on, changed to UEFI Hybrid (with CSM) and Legacy, but nothing works.
Does anyone have any suggestions?
To avoid Issues, I would suggest to let Secure Boot disabled.
When You still have Windows installed or somewhere a Windows PC, I would recommend to use Rufus for creating the Bootstick. In Rufus, You can set up on the ''Partition Sheme'' Option GPT for Your UEFI BIOS. Do that and format the USB Stick to FAT32 and then try it again.
Thank you for that suggestion.
Sadly it didn't work.
As another option, I have just tried to use Legacy BIOS and formatted the USB drive using MBR and target of BIOS or UEFI and that doesn't work either.
Any more suggestions?
