Live iso does not boot directly in UEFI mode

[tomshoo]

Description

Live ISO for elementary os 6 does not boot in UEFI mode unless manually configured.

Steps to reproduce

• Burn the ISO as mentioned in the installation guide
• Reboot the system and enter the Boot Menu(F12 key for dell laptops)
• Select the USB drive containing the ISO

Error

How I resolved it

• After entering the boot menu, go to the BIOS settings
• Go to boot sequence, and select add boot option
• Name it whatever you want and specify the path to FS1/EFI/boot/grubx64.efi
• Reboot
• Enter the boot menu and select the Boot option you created earlier
• Install the OS

Note

I also tried burning the iso using dd but the outcome didn't change, so I had to resort to manually adding a boot entry and then deleting it after the install process was over

Thanks for the report!

This looks to be a duplicate of elementary/triage#74 which is an upstream Ubuntu issue. I'll close this issue so we can keep track of it in one place. Thanks for detailing your workaround.

One thing to do is to select the boot file after burning the image on the device. The following script code can do the job:

efibootmgr --create --label Elementary --disk /dev/<device> --loader "\EFI\boot\grubx64.efi"

efibootmgr --create --label Elementary --disk /dev/sda1 --loader "\EFI\boot\grubx64.efi"

I guess the disk should point to /dev/sdb (sdb in my case because that was where the iso was burnt.

Yep, I totally forgot to generalize that. I'll edit it.
