grub2 does not discover small linux partition

English Install/Boot/Login
1

I installed Windows 7 and it is encrypted by special program which is making small linux partition (normally it is booting from this small linux partition, asking for password and then unencrypts Windows).
After installation Grub didn’t discover this small Linux but I can mount is and I see it’s files:


 # mount /dev/sda2 mnttt/
 # ls mnttt
bin  boot  .CT_devices  dev  etc  .fonts.cache-1  lib  libexec  LICENSES  linuxrc  lost+found  mnt  mod  opt  proc  root  .safesign  sbin  sys  tmp  usr  var
 # ls mnttt/boot/
alpha1_mask.ppm.gz  bkgrimage.mask.ppm.gz  black.mask.ppm     black.ppm     bzImage           bzImage.2.6.34.8-acpi      bzImage-acpi      grub
bkgrimage.mask.ppm  bkgrimage.ppm.gz       black.mask.ppm.gz  black.ppm.gz  bzImage.2.6.34.8  bzImage.2.6.34.8-poweroff  bzImage-poweroff

How can I tell Grub2 to add this to menu? I tried:


grub2-install /dev/sda
grub2-mkconfig -o /boot/grub2/grub.cfg

but it didn’t help.

I’m sure that it can be done because I did it somehow before but I can’t remember how :\

PS. Os-proober discover this small Linux:


# os-prober 
  No volume groups found
/dev/sda2:unknown Linux distribution:Linux:linux

and this is how partitions looks now:


# fdisk -l

Dysk /dev/sda: 180.0 GB, bajtów: 180045766656, sektorów: 351651888
Jednostka = sektorów, czyli 1 * 512 = 512 bajtów
Rozmiar sektora (logiczny/fizyczny) w bajtach: 512 / 512
Rozmiar we/wy (minimalny/optymalny) w bajtach: 512 / 512

/dev/sda6       207689728   351631359    71970816   83  Linux

Interesting is that mkconfig is discovering it but not adding to menu:


# grub2-mkconfig -o /boot/grub2/grub.cfg 
Generowanie grub.cfg...
Znaleziono motyw: /boot/grub2/themes/openSUSE/theme.txt
Znaleziono obraz Linuksa: /boot/vmlinuz-3.11.10-7-desktop

Znaleziono obraz initrd: /boot/initrd-3.11.6-4-desktop
  No volume groups found
Znaleziono unknown Linux distribution na /dev/sda2
gotowe

“Znaleziono obraz” means “found image” :wink:

It is easier for you (no need to translate) when you execute the commands in this way:

LANG=C fdisk -l

Then the English words will be used.

4

Now we do not know what the partition type

95  Nieznany

is. I tried to ask fdisk, but it is not in it’s list.

5

Please show “ls -l mnttt/boot/grub” and content of “mnttt/boot/grub/menu.lst”

6

It is ext2 partition.


# mount | grep sda2
/dev/sda2 on /home/kamil/mnttt type ext2 (rw,relatime)

# ls -l mnttt/boot/grub

But now sytuation is a little different. Before Windows partition was unencrypted and Grub2 discovered Windws automaticaly.

I found how it was configured!!! :slight_smile:

Thanks for help!

@hcvv, nice hint with this language, thanks!

That is not what my remark was about. I talked about the type of the partition (shown in hex in the Id column and as text in the System column by fdisk -l).

You talk about the file system type you have on the partition (ext2). There is only a remote connection between the two. Most often the partition type for any Linux file system types is 83.

You can see that partition type as a sign of intention on what the partition is (to be) used for. It depends totaly on the software that works with it if it is tested and if there are any consuquenses connected with such a test. Thus I was wondering if such a strange partition type like 95 could be a sign to GRUB to skip it as a partition to look further into.

11

OK, so it means that I can mark it as 83 and it have to discover it automatically?

12

You are jumping to conclusions. I did not say that. I said that I wondered why it is strange. And I stated that it could be that GRUB finds it also strange.

First thing to know is of course why it is as it is. Who or what did it, or when was it done, why was it done, etc.
What does it mean (maybe when we know the answer to the first question, we understand this one or vv.).

And then we might come to the conclusion that changing it, is also making it better.

We also might come to the conslusion that it has nothing to do with your problem (but still might better be changed).

I realy do not know. You offer us a problem, and I point to things I find strange and that IMHO need further investigation.

13

I have no idea why it is like that. This partition is created by program which prvides Windows partition encryption and special boot interface.

I tried to change partition type and it didn’t help grub to discover it. Also with other tryes I totally destroyed Grub :wink:
I think that I’ll leave it like it is with 40_custom configuration. Thanks for your help!

14

When os-prober discovers Linux it also expects to find bootloader stanzas to load Linux; in this case as it is grub2 it expects to find “linux …” command in menu entry. Because this command does not exist in your case, it outputs nothing.

Every heuristic has its limits …

15

Only one more question. I have this custom menu entry but I can’t find in any documentation how I can make it default? Any ideas? :wink:

16

YaST->System->Boot Loader->Boot Loader Options, or the “GRUB_DEFAULT” setting in /etc/default/grub.

But I never tried it with custom menu entries because I have none.
