After install Opensuse 15.5 (Leap or Tumbleweed) I get a Bash ? GRUB >
 

I have a mini pc T8 plus CPU Alder Lake N100 Ram: 16 GB and ROM: 512 GB. I use PC only for Linux install. After install I remove USB stick for a restart computer. Then appear a Bash text and GRUB> I don't knowm what to fill in after GRUB> . I would like he starts with Opensuse! But I use the TAB key. See also photo's. Other distro's no problems.: Ubuntu, Zorin, Neon, Mint or Manjaro.

I don't know anything about your hardware but when you get the grub prompt as shown in your image, it means you didn't properly install the Grub bootloader. To gather information when you see: grub> type in ls to show drives and partitions. Type ls /boot/grub to see what files are there. For more details on this go to the site at the link below to the Linux Foundation which gives a lot of information on booting with Grub. ls /boot should show the kernels. ls /boot/grub should show the grub files. Is this an EFI or Legacy install? Do you know the difference.

The Leap and TW installation media provide a menu selection to boot the installed system. You should do that, then when the installed system is running, go into system setup "YaST" Bootloader section to reinstall the Grub bootloader, making sure that your choices all match your BIOS configuration. If doing so does not solve the problem, boot using that method again, then collect information from the following to copy and paste here all of it (using code tags):You may need to prepend "sudo" to one or more of these commands, or else run them logged in as root, or after running su -.

I used Yast,for install GRUB (someone by Tweakers came with that answer) and I also looked at the BIOS during startup and specifically checked whether secure boot had perhaps changed. But I did see that opensuse was not selected as the first option. This changes. At startup I now get the option, generated by Opensuse itself, to start up with opensuse tumbleweed and some other options. First possible, opensuse tumbleweed, clicked on it and sure enough it starts up effortlessly. Maybe because of Yast or my changes in the BIOS. It is solved. And opensuse boot menu is much clearer and nicer than Grub. My opinion. And maby it is from Grub2. Thanks everyone, for they thoughts. I think its is solved.

The last time I installed Opensuse it had more options than one usually sees when installing Grub which is good but can cause problems for new users. I guess you didn't find the site below detailing installing/reinstalling Grub on Opensuse but if you plan to use Opensuse, I would suggest you bookmark the site. It has information specific to Opensuse/Yast as well as Grub in general.

Thanks Yancek very helpfull, I spread the link further.

I doubt any but an expert with Linux and/or openSUSE (note correct spelling) would be able to install openSUSE without resulting in Grub providing its boot menu. Have a lot of fun! :)
