[Spce-user] mr13.5.1 Bare Metal Installation woes

[Newbie]

'Morning all,

1. Expected Behaviour

After selecting "CE" from the menu, grml installer leaves bootable
mr13.5.1 on the SSD after installation completes.


2. Actual Behaviour

After selecting "CE" from the menu, grml installer prints:

...
* Successfully verified /conf/bootid.txt from ISO, continuing...
...
[  OK  ] SecureBoot not detected
[  OK  ] You seem to have logical volumes (LVM) on your system !1
[  OK  ] Bootparameter scripts found.  Trying to execute from
          directory /run/live/medum/scripts
[  OK  ] Executing grml-sipwise specific checks...

Then after selecting < Yes > to alert "Do you want to check the
install media?" it immediately alerts "Integrity check failed.
Reason: The media check is complete the result is: NA.
File not found.  Abort installation or continue anyway?" and
continuing, the installer completes printing:

Writing /etc/debian_chroot ....
umount: /mnt/sys/firmware/efi/efivars: no mount point specified.
umount: /mnt/boot/efi: no mount point specified.
umount: /mnt/proc: not mounted.
umount: /mnt/sys: not mounted.
umount: /mnt/dev/pts: not mounted.
umount: /mnt/dev: not mounted.

Installation finished. \o/

Successfully finished deployment process [Tue Oct 28 17:27:21 UTC
2025 - running 2158 seconds
Do you want to [r]eboot or [h]alt the system now? (Press any other
key to cancel.)

After selecting reboot, the BIOS prints:

No boot device has been detected, please press any key to reboot!

If the grml rescue is entered, the lvms are visible but inactive:

lvm> lvscan
   inactive      '/dev/ngcp/root' [10.00 GiB] inherit
   inactive      '/dev/ngcp/fallback' [10.00 GiB] inherit
   inactive      '/dev/ngcp/data' [192.78 GiB] inherit
lvm> lvchange -a y /dev/ngcp/root
lvm> lvchange -a y /dev/ngcp/fallback
lvm> lvchange -a y /dev/ngcp/data
lvm> lvscan
   ACTIVE        '/dev/ngcp/root' [10.00 GiB] inherit
   ACTIVE        '/dev/ngcp/fallback' [10.00 GiB] inherit
   ACTIVE        '/dev/ngcp/data' [192.78 GiB] inherit
lvm>

Without success in making it bootable.  Using BIOS to target 1st,
2nd, 3rd disks to boot from it prints on each occasion:

Failed to load COM32 file /boot/addons/chain.c32 !2


3. Additional Context

Except for not meeting the minimum required h/w spec, followed the new
install spec on p16/488 of the handbook-ce_mr13.5.1.pdf to the letter.

The ISO checksums match:

 From the distribution site:

$ cat sip_provider_mr13.5.1.iso.md5
c55366184178226cd320d7797cce1f8f  sip_provider_mr13.5.1.iso

$ cat sip_provider_mr13.5.1.iso.sha1
863cb6cf3c42a794c1ea55efe8b76243814404e2  sip_provider_mr13.5.1.iso

Checked against both the saved ISO file:

$ sha1sum sip_provider_mr13.5.1.iso
863cb6cf3c42a794c1ea55efe8b76243814404e2  sip_provider_mr13.5.1.iso

And against the USB drive made from it:

$ head -c $(stat -c '%s' sip_provider_mr13.5.1.iso) /dev/sdc ! sha1sum
863cb6cf3c42a794c1ea55efe8b76243814404e2  -


!1: Originally the LVMs detected message was not printed, understandably
the message is printed after repeated installations.

!2: chain.c32 is not in addons but in isolinux:
