'Little' GRUB problem. Help! :(

[Grisnackh]

Hy!

I've got a problem with GRUB. I'm a new Fedora user, but I've got another Linux system (BlackPanther) on sda1. Fedora is on sda7. So, after I'm installed Fedora and updated it (the GRUB, too), from the GRUB menu disappeared my another Linux distro. I read some description about this problem solving, but I'm not a big...'master' on informatic's platform. Anyway, my english is horrible too, I know...
So, is there anyone, who give me a step-by-step, thorough description?

Open a terminal and type

PHP Code:

su -c 'grub2-mkconfig -o /boot/grub2/grub.cfg' 


Reboot and see if your other OS is part of the boot menu.

Thank you, man! But it's not good.
I typed it to the terminal, and this came out:

"Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.2.5-3.fc16.i686
Found linux image: /boot/vmlinuz-3.1.0-7.fc16.i686
Found initrd image: /boot/initramfs-3.1.0-7.fc16.i686.img
No volume groups found
Found blackPanther OS 11.1 (11.1) on /dev/sda1
done
"
It's okay, I reboot, but in the menu still there isn't bP. :/

When I partitioned for Fedora, I don't picks bP's partition, so (in principle) it's good. But shouldn't have been found more Linux image? In bP, there's 2.6.38.2 kernel, but I'm not see it in the list. I don't understand...

Boot Fedora, open a terminal and type

PHP Code:

su -c 'fdisk -l' 


Post that output here please.

I find it rather intersting that grub DOES find your bP installation:

Whats the output of:

cat /boot/grub2/grub.cfg|grep menuentry

EDIT:
Do you have a seperate boot partition?
If so, whats the output of:

lsblk ; blkid

[sea]

Try booting into the 'linux', 'linux-nonfb' or the 'failsafe', as they all refer to sda1.
Please report if it was working (boot successfull to black panther or not).

I tried it, but it wasn't working. It wrote this:

"VGA 778 is deprecated. Use set gfxpayload 800x600x16, 800x600 before linux command instead.
error: no such partition

Press any key to continue..."

So, I pressed one key, and the consequence is:

http://kepfeltoltes.hu/view/120212/P...toltes.hu_.jpg

I tried document it. From this step, it doesn't go forward.
Any idea?

Hmm lets get your hands dirty

Go for this:

su
cp /boot/grub2/grub.cfg /boot/grub2/grub.bak
gedit /boot/grub2/grub.cfg

1) Replace gedit with your prefered gui editor.
2) Scroll down the the menuentry "linux (on /dev/sda1)" --class gnu-linux --class gnu --class os {
and mark everything till the closing }.
3) Paste that part here within either code or quote tags

Do you think of this?
But...if "ext2" is the file system...why? bP-s file system was ext3, I think. No way ext2.
And...what's msdos? I don't understand it. :S

Have a closer look at the bold ones...

EDIT:
Copy this text and append (add at the end of existing code in there) it corrected to: /etc/grub.d/40_custom
However, id rename 'linux (on /dev/sda1)' of the first line to something like: 'black Panther - custom'
Yes this will make another entry to your boot menu, but that entry wont be changed!
I suggest this because grub seems to cut off your UUID of sda1.

I shame it, but I disturbed to this totally... My boyfriend tried to solve my problem, so there may be some interesting thing...

[sea]

There is a file in the folder /etc/grub.d that is called 40_custom.
To that file you add (below the current lines in there).

menuentry "Black Panther (on /dev/sda1)" --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext4
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root /dev/sda1
linux /boot/vmlinuz BOOT_IMAGE=linux root=UUID=c5b3c48c-963e-4dab-8cd2-0e58bcd707db
initrd (hd0,0)/boot/initrd.img
}

You need to open that file with root rights, or you wont be able to save it.

Hope this helps, i'm off to sleep

Ahh...I think, this is the problem. I can't find that file anywhere.
