Blind leading the blind.

Have you tried enabling BIOS legacy mode in your PC?

This is not good advice.

You need to find out exactly what the problem is, and the OP hasn't been clear about that

But the OP said:

So it is fair to assume the OP had already messed with BIOS. Now, BIOS to me sounds like BIOS legacy mode. -- Ottavio -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

it's this that is surprising, but as I couldn't follow all the thread I may have missed something

I do not know of any distribution that supports UEFI Windows and CSM-BIOS Linux installations. At the least you are stuck depending on the firmware's boot manager to switch between Linux and Windows, because a BIOS GRUB will not boot a UEFI Windows.

Quick Boot [Enabled] Disabled Boot Up Num-Lock Status [On] Off Keyboardless Operation [Enabled] Disabled

To make the install of openSUSE possible is was necessary to change Boot Mode to Legacy Only (Boot Priority disappears then).

Did you try changing CSM from Enabled to Disabled? What problem did you encounter? My suggestion is that you focus on troubleshooting installation and boot problems with the firmware on settings that can be supported. The state of the firmware settings as you have them are supportable only with significant experience with the particular firmware and OS's you are using, and most people won't have that experience.

After 'restart' (and DVD removed) I got the known four green choices and started openSUSE. The joy was short. After installing the last snapshot 20150712 I get only 'error 1962 No OS available' Is there somewhere detailed documentation available how to install openSUSE in such an UEFI BIOS?

I strongly suggest regression of the firmware settings. I would try to find a reset to defaults option in the firmware setup. And then make sure the firmware is set to the current version available by the manufacturer. Then I'd check the firmware settings and make sure CSM is disabled, which ought to mean Boot Mode gets set to UEFI only. If you have video related problems at boot, it could mean you have newer hardware than the kernel currently supports, so you might need to use a basic video boot option, or add the word nomodeset to the boot parameters when booting the install media. You may need to continue using that parameter until you get a newer kernel with the proper support or otherwise troubleshoot how to get it working. But I wouldn't just choose the CSM option to get around having to do this: CSM mode tends to come with a lot of performance limitations. So I'd try to stick with making this UEFI only business work until you hit a brick wall, which most people don't fortunately. Before installing, optionally wipe out the BIOS GRUB boot.img written into LBA 0. It probably won't cause any problems leaving it there, the UEFI spec says it should just be ignored. But... if you want to get rid of it, you'd use: dd if=/dev/zero of=/dev/sdX bs=440 count=1 ## where X drive letter only, do not specify a partition, definitely make sure you get the count of 1 in there or it'll quickly be zeroing the entire drive...

From the life environment you can confirm booting in UEFI mode with:

efibootmgr If you get an error message, then the CSM is still being used. If you get a short listing of what look like boot options (or at least no error message) then it's booted in UEFI mode. -- Chris Murphy -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't know what is CSM, but for sure grub can boot UEFI windows (may be simply launching EFI binary) - at least grub-efi (install in uefi mode)

jdd

From Wikipedia To ensure backward compatibility, most UEFI firmware implementations on PC-class machines also support booting in legacy BIOS mode from MBR-partitioned disks, through the Compatibility Support Module (CSM) that provides legacy BIOS compatibility. In this scenario, booting is performed in the same way as on legacy BIOS-based systems, by ignoring the partition table and relying on the content of a boot sector. -- A cat is a puzzle with no solution.

I don't know what is CSM, Compatibility Support Module. It is a faux-BIOS presented to the operating system to treat the system as if it has BIOS firmware instead of UEFI firmware. If a CSM is used, then the bootloader will be BIOS based, not UEFI based.

but for sure grub can boot UEFI windows (may be simply launching EFI binary) - at least grub-efi (install in uefi mode) No because the Linux distro installer will install a BIOS based bootloader, which won't chainload a UEFI bootloader.

A friend bought a new Windows 8 HP computer and wanted Windows Seven on it. I used a live CD to delete the old partition scheme and tried to install Windows 7. I had to go in and disable Secure Boot and enable Legacy Boot in order to install Windows 7 on the blank hard drive. -- A cat is a puzzle with no solution. Cats are tiny little women in fur coats.

well, I probably misunderstood your post. you can't have *at the same time* windows uefi and linux legacy, the boot have to be the same for the two systems. most of the time you can install either boot legacy or uefi for linux, but I found at least one hardware that do not boot openSUSE (nor ubuntu) in uefi mode. It was still possible to have the two of them, but going to bios at any boot change.

What "installing" means? Did you update existing openSUSE 13.2 installation? Did you install Tumbleweed from scratch from installation media? In this case did you install it in the same partitions or selected new partitions?

...

Is there somewhere detailed documentation available how to install openSUSE in such an UEFI BIOS?

Usually you put installation DVD in drive (or plug USB stick) and start from it.

and how do you get it to do that if it ignores the _.iso in the DVD drive? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
