Then I restarted my computer and booted into Linux Kubuntu 21.10. I installed Grub Customizer on it. With it, I supplemented the boot menu with a section that allows you to select Linux OpenSuse. I saved the changes to the boot menu. I restarted my computer and chose Linux OpenSuse to run. The system has booted up and is working properly. I tried to modify a boot menu entry from within YAST. When trying to save the changes, the following message was displayed: Unable to execute [["/usr/sbin/grub2-install","--target=/x86_64-efi", "--force", "--skip-fs-probe"]] Exit code: 1 Error message: Installing for x86_64-efi. Could not prepare Boot variable: Success /usr/sbin/grub2-install: error: efibootmgr failed to register the boot entry: Input/Output error I restarted my computer and went to UEFI settings: "Boot -> UEFI Hard Disk Drive BBS Priorities". There are 4 items in this option. The first one decides which boot loader will be run. I chose the entry: "opensuse". I saved the changes to UEFI settings. After the computer restarts, Linux OpenSuse starts automatically. Unfortunately, there is no boot menu. After starting the above-mentioned system, I tried to modify the boot menu entries, but the effect is the same as described above. So I abandoned the idea of creating a boot menu based on "GRUB2 for UEFI". I will choose the system to run in UEFI. Additionally, when I started Linux OpenSuse for the first time, it turned out that the system does not support audio. This is the same problem as with Linux Kubuntu. Searching this case on the Internet shows that this situation occurs in virtually every newer Linux distribution. This is caused by invalid entries in Linux configuration files when it is installed on Intel-based (SoC) computers that have integrated audio support. I solved the problem similarly to Linux Kubuntu, based on the description from the website: https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.htm... After making changes to the configuration files and rebooting the computer, the sound works fine. Due to the fact that probably very few people use such computers as described by me, it is unprofitable to investigate the cause of the problem with saving settings. So it is probably best to archive and disable (or delete) this report. -- You are receiving this mail because: You are on the CC list for the bug.
