Load an iso as boot entry on systemd boot loader

derverzweifelte · 2017-11-13 19:03:27

Hello, my laptop is currently a bit broken, so I wanted to install another OS with more compatible wifi drivers.

My biggest issue is that the BIOS/UEFI menu is skipped and the OS (arch linux) is instantly started. There is no way to access the BIOS even if I select it in the bootup process it just gets skipped.
This is a bug of the laptop (lenovo g580) and is already known.

So my goal is to install an OS by using an image when the boot loader is trying to select a file to start.

My system has only system-d boot loader and I am not sure how I can create a boot entry with the iso file.

Any help is appreciated.

Kind regards

Does running this from Arch get you into your firmware menu?

systemctl reboot --firmware-setup

As for your question systemd-boot doesn't support booting from iso files, you could switch to grub instead which does have this functionality.

sudo systemctl reboot --firmware-setup prints the following message: Cannot indicate to EFI to boot into setup mode: No such file or directory. I try to install grub then. However is that possible on a running linux machine?

Thanks for you answer
