OS selection at startup
I recently installed another Linux system on one machine which already has Windows and Leap 15.3. The problem is that the "new" Linux has installed its own operating system selector at boot-up, and it's hard to read and quite fast. Is there any way to get back to the Leap-installed boot selector? (If so, how? thanx--doug

easy. * if UEFI, go to firmware and choose what system you want * else, your new system should be able to boot also 15.3. There go to yast, startup, change the boot delay and ok, the boot will be redone jdd -- http://dodin.org

easy.
* if UEFI, go to firmware and choose what system you want I suppose this is just another example of my stupidity, but
a) how do I know if it's UEFI? Neither lshw nor dmidecode shows that acronym. MOBO is ASROC H310CM-HDV/M.2 in a computer about -1/2 years old. b) Let's say it does use UEFI, how do I "go to firmware?"
* else, your new system should be able to boot also 15.3. There go to yast, startup, change the boot delay and ok, the boot will be redone
I don't think the new system uses yast. It's not a Suse variant. It will boot 15.3 if I'm_real quick_ in selecting it out of gray letters on dark gray background. Probably also Windows. That's the problem in a nutshell.

Thanx for your assistance--doug

Because you should know.
MOBO is ASROC H310CM-HDV/M.2 in a computer about -1/2 years old.
Then it is UEFI.
b) Let's say it does use UEFI, how do I "go to firmware?"
How did you go to BIOS on old machines? Same thing. Press certain key some number of seconds after powering up. The book you got with the machine (or the MOBO) should say. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))

The machine was bought from Micro Center on Long Island, and came with nothing but a receipt. But with any sort of luck, I can find a poopsheet on the MOBO with Google. --doug -- This email has been checked for viruses by AVG. https://www.avg.com

Don't give me that crap. ftp://asrockchina.com.cn/Manual/H310CM-HDVM.2.pdf 20 seconds to find it. 4.10 Boot Screen This section displays the available devices on your system for you to configure the boot settings and the boot priority. -- Cheers / Saludos, Carlos E.

if you have an EFI partition, probably monted in /boot/EFI, it is. Given your mobo is recent, it's most probably uefi compatible

should be in the manual. sometime displayed on the boot screen. Try pressing at boot the key: ESC, F2, CR (Enter), DEL
* else, your new system should be able to boot also 15.3. There go to yast, startup, change the boot delay and ok, the boot will be redone
I don't think the new system uses yast. It's not a Suse variant. It will boot 15.3 if I'm_real quick_ in selecting it out of gray letters on dark gray background. Probably also Windows. That's the problem in a nutshell.
you have to use yast *after* booting 15.3. You have to do this only once, after making the modif, 15.3 will boot as default I know these new computers boot very fast :-) jdd -- http://dodin.org

make any change in yast2 bootloader man efibootmgr https://en.opensuse.org/openSUSE:UEFI When time comes to update a kernel on the other Linux, it will again usurp control from openSUSE. I handle that two ways: 1-uninstall bootloader from the other distro, and/or 2-eliminate mounting any ESP partition from the other distro's fstab Only one Gnu/Linux bootloader per PC is normally needed. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
