Newly-installed Leap 42.1 OS not available in bootloader

w2tq · June 14, 2016, 1:26am

I installed an additional Linux system (Leap 42.1) in previously-unused space on a drive that has a SuSE 13.2 system. Here is the configuration of the drive (from the install process drive configuration dialog and now showing in the 13.2 partitioner [less the “/” mount point in the latter]):

/dev/sde    476.94 GB

/dev/sde1       2.01 GB             Linux swap     Swap     swap    [SuSE 13.2]
/dev/sde2      99.61 GB            Linux native     Ext4      /

/dev/sde3    375.31 GB             Extended
/dev/sde5    375.31 GB       F    Linux native    BtrFS     /          [Leap 42.1]

The current version of grub2 in 13.2: 2.02~beta2-20.14.2

I took the default options in the bootloader dialog:

Booting
        . . .
        Change Location:
            Install bootcode into MBR [do not install]
            Do not install bootcode into “/” partition [do not install]

When the installation completed (with updates), the system rebooted into 13.2 but does not provide an option for 42.1 on the boot loader page. Nor is it available under the bootloader option tab in Yast2/bootloader (in the 13.2 system).

Will the command “grub2-mkconfig -o /boot/grub2/grub.cfg” detect and add the new system to the bootloader and grub?

Thank you.

You left 13.2 in charge you must now tell it a new OS is installed.

In Yast -boot loader set scan for foreign OS box that should find it

w2tq · June 14, 2016, 2:36am

gogalthorp -

Thank you for the reply.

In YaST2 > Boot loader > Bootloader Options (third or right-most tab), the option “Probe Foreign OS” is (and was) checked.

Is that what you meant by “set scan for foreign OS box?”

I also ran os-prober in the shell with no luck on 42.1 Only two other installations popped up: Windows XP and openSuSE 13.1, both on other drives; these are available on the boot loader page when the machine starts up.

gogalthorp -

On a hunch, I checked and found more recent versions of os-prober (as well as grub2, of which I was aware). I just updated both os-prober and four grub2 files (grub2-2.02~beta2-20.14.2.x86_64; grub2-i386-pc-2.02~beta2-20.14.2.x86_64; grub2-x86_64-efi-2.02~beta2-20.14.2.x86_64; and grub2-snapper-plugin-2.02~beta2-20.14.2).

Leap 42.1 now appears in the os-prober results and in YaST2 bootloader options.

Should I now run the “grub2-mkconfig -o /boot/grub2/grub.cfg” command?

gogalthorp · June 14, 2016, 5:47am

You can or just do it in Yast a small change and back again then accept. A tweak will make Yast modal think a change is made and thus rebuild things. Using the command line is ok too bu I think Yast is less prone to mistakes

w2tq · June 14, 2016, 1:05pm

I do not see any option in Yast other than to select a specific default installation, which is not what I’m attempting to do here.

The issue now seems be that the bootloader menu is not updating. Running “update-bootloader --refresh” did not resolve the issue.

And 42.1 is showing in grub.cfg:

How do I get 13.2 to update the menu? grub2-mkconfig?

w2tq · June 14, 2016, 10:42pm

Does anyone know how to refresh/repopulate the bootloader menu (the splash page with boot options at login)?

w2tq · June 14, 2016, 11:36pm

While waiting for a response to my query immediately above, I ran grub2-mkconfig, but the menu remains without the 42.1 entries, even though the YaST bootloader lists them:

I don’t think the lvmetad warning applies in my situation, but I may be wrong about that.

(I hope that I do not have to uninstall and then re-install grub2.)

Hi,
Did you install bootloader for Leap as well?
If 13.2 is your bootloader, your above grub2 config should work, IMHO.

w2tq · June 15, 2016, 9:14am

Peter_Abc -

In the opening post, I indicated that I accepted the default options in the bootloader dialog:
Code:

Booting
        . . .         Change Location:
            Install bootcode into MBR [do not install]
            Do not install bootcode into “/” partition [install]

The MBR is on the drive where I initially loaded 13.2 (see the first code section in the opening post for the drive layout).

Is the second and last line where the problem occurred?

w2tq · June 15, 2016, 9:50am

Further, if bootcode should have been installed in both 13.2 and 42.1, how would I now install the bootcode in the second location?

knurpht · June 15, 2016, 9:50am

I think you’re missing something: the MBR code is pointing to the GRUB install of your 13.2 . So, you need to boot 13.2, and use Yast’s bootloader module ( f.e. change the delay from 8 to 7 seconds ) to force the bootloader configuration and install to be regenerated.

w2tq · June 15, 2016, 11:38am

Knurpht -

Thank you. I do boot into 13.2 - that and the legacy 13.1 and Windows XP are the only options available on this pc. And the 13.2 installation is my main production workstation (with virtual machines, Win 7, etc.).

What is missing from the bootloader menu is the 42.1 - I am currently unable, short of using a rescue disk, to log into 42.1

I am now and have always been in 13.2. And I’ve accessed the Yast boot loader many times (see post #4 where I stated that 42.1 is now showing as an option). And have reloaded it as well.

In the Yast bootloader, under the first tab (boot code options), under Boot Loader Location, the second of three (Boot from Root Partition) is checked. The first and third (Boot from Master Boot Record and Boot from Extended Partition) are not checked. “Set active Flag in Partition Table for Boot Partition” and “Write generic Boot Code to MBR” are also checked.

The Kernel parameters (second tab) were left as is.

The third tab, bootloader options, Timeout is now 8 seconds. If I understand your comment, I need to reduce that to 7. (I guess that is to make Yast think the configuration has changed, which I believe I accomplished previoulsy by unchecking and then re-checking a box.)

Hi,
I realised after posting my 1st reply that you have openSUSE 13.1
reported by ‘grub2-mkconfig -o /boot/grub2/grub.cfg’ but you keep
writing about 13.2. I have leap and 13.2 and kernel version looks like
13.2 (but not latest).

FYI, Knurpht and gogalthorp are the Linux Gurus in this thread and you
should take their advice before anything I say. I am a novice and just
an ordinary openSUSE user who is using a multi-boot pc with Leap 42.1 (2
installs, Gnome and Xfce), openSUSE 13.2 KDE4, openSUSE 11.4 Gnome 2.32,
Centos 6.8 and 7.2 and Mint 17.3 Xfce and I have been sorting out some
issues recently. My system has Leap 42.1 Grub2 on MBR and on the other
OSes not installed at all (but that may not be the best option?). I
previously had Mint 17.3 as the Grub2 boot controller and accidentally
forgot to opt out from installing Grub2 to MBR when upgrading 13.2 to
Leap 42.1 Gnome. Thus when you install grub/2 to MBR on one OS it should
take over from the other.

How to install Grub2 to MBR
As Knurpht advises, go to Yast2 (Control Center) —> Boot Loader
(Module) and go through the options there to install Grub2 for your
preferred openSUSE OS. I have used that option a few times and it works
good. Though all my OS partitions are on /dev/sda (one hdd on laptop)
and my Linux fs are ext4.

Cheers,
Peter

I just reloaded the bootloader configuration in Yast and rebooted. 42.1 is still missing from the bootloader menu on startup. And /etc/boot/grub2/grub.cfg bears a new date time. Here is the /grub.d/30_os_prober excerpt from grub.cfg (no change from before):

### END /etc/grub.d/30_os-prober ###

I am unable to figure out why 42.1 is not captured. Peter_Abc mentioned bootcode on the 42.1 partition (see posts 9-11).

What a puzzle!

Peter_Abc -

The 13.1 and 42.1 os_prober was obtained from 13.2. I no longer boot into 13.1 (or XP). Default is 13.2 on /dev/sde; 13.1 is on /dev/sda.

Now I see you also have 13.1 on /dev/sda.

This problem is over my head and I will just post a copy of my leap 42.1
/etc/default/grub file (which is editable) in case it is of any help to
use as a guide and let the experts try to help you sort your issues out.

THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader

For the new kernel it try to figure out old parameters. In case we are

not able to recognize it (e.g. change of flavor or strange install order
) it it use as fallback installation parameters from
/etc/sysconfig/bootloader

If you change this file, run ‘grub2-mkconfig -o /boot/grub2/grub.cfg’

afterwards to update

/boot/grub2/grub.cfg.

kernel command line options for failsafe mode

GRUB_CMDLINE_LINUX_RECOVERY=single

This works with Linux (no patch required) and with any kernel that obtains

the memory map information from GRUB (GNU Mach, kernel of FreeBSD …)

Uncomment to disable graphical terminal (grub-pc only)

The resolution used on graphical terminal

note that you can use only modes which your graphic card supports via VBE

you can see them in real GRUB with the command `vbeinfo’

#GRUB_GFXMODE=auto

Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to

Linux
#GRUB_DISABLE_LINUX_UUID=true

Uncomment to disable generation of recovery mode menu entries

#GRUB_DISABLE_RECOVERY=true

Uncomment to get a beep at grub start

#GRUB_INIT_TUNE=“480 440 1”

Skip 30_os-prober if you experienced very slow in probing them

#SUSE_BTRFS_SNAPSHOT_BOOTING=true (normally enabled)
