Hello Folks,
I wanted to do a clean install of Solus on my Acer Travemate-X349-G2-M today and ran into several issues with installing in UEFI Mode. (legacy works fine...)
Note: I had issues installing it the first time (about one year prior) but I was able to resolve it.
It seems that the acer firmware handles UEFI Booting in a strange way. To be able to create an entry in the "boot menu" you have to enable secure boot and add the EFI file to "trusted sources" (this fixed my issue the last time). You have to do this for the USB Installer and for the OS after the installation process. There are several threads in forums of different Linux distributions regarding this issue (ubuntu, archwiki, etc...).
Unfortunatly this workaround was not working for my fresh Solus (4) installation this time around. Re-writing anything in the ESP from Solus live disk (bootctl; efibootmgr) was unsuccessful. After adding the EFI file under \EFI\systemd\systemd-bootx64.efi in the Acer BIOS under trusted sources, I get an error like:
"Error loading \EFI\com.solus-project\kernel-com.solus-project.current.4.20.16-112: Not Found"
"Failed to execute Solus 4.0 Fortitude \EFI\com.solus-project\kernel-com.solus-project.current.4.20.16-112: Not Found"
after that I get an error from Acer BIOS saying that the boot failed and no recovery media could be found.
I made several resets of the BIOS and fiddled with it a lot. Has anybody seen something like this before, and could advice me? I have no idea how i could troubleshoot the problem further.
Thanks in advance guys 🙂
