Cannot add custom menu entry to GRUB2 bootloader [Solved]

[donnie]

Tried to make things correctly, instead of just manually editing /boot/grub/grub.cfg. Emerge does not help, and many many errors:

Code: Select all

I will end up manually editing grub.cfg again, help!

moved to correct forum, please post in correct forum

Are you sure you have synced with layman and portage and are fully up to date with entropy? I guess I don't understand what you are really tying to do as the post really doesn't make sense other than grub wont merge

Code: Select all

wolf64 wolfden # emerge -av grub

These are the packages that would be merged, in order:

I synced layman, portage, and updated equo, upgraded entropy, sulfur, grub, and configs. Now equo upgrade started.

I'm trying to install SystemRescueCD to HDD, I did it a couple of times before. When I edit grub.cfg, QEMU shows that it really adds menuentry, and I can boot Sabayon, but not SRCD, messages are:

Doesn't boot!

I am sure this is because DO NOT EDIT THAT FILE, but how to edit it in any manner? update-grub and update-grub2 does not exist!

Im scared to reboot

Trying to understand this.

You installed SystemRescueCD

The menu entry is there in Grub?

SystemRescueCD just wont boot?

So if it's in the grub menu entry and you can select it, but it don't boot, it would than appear that something is wrong with the entry.

I believe you are needing grub-mkconfig

The configuration file is called /boot/grub/grub.cfg, and it generates the boot menu you see on your screen when you boot your PC (and so, /boot/grub/grub.cfg can be called the boot menu configuration file). You are NOT supposed to edit it (it is read-only). It is generated from a folder of scripts called /etc/grub.d. Another key file is /etc/grub/default and it feeds default data to the scripts in /etc/grub.d. You may edit /etc/grub/default (as root). You may also edit the scripts in /etc/grub.d (as root). If you create a new file in /etc/grub.d, you must make it executable if you want the entry included in the configuration file grub.cfg. If you do not want a script to execute (and so remove that entry from grub.cfg), you must remove the execute bit (i.e., remove the execute permission).

>>> Key reminder:
Generate a new grub.cfg after changing anything in /etc/default/grub or /etc/grub.d by:
grub-mkconfig -o /boot/grub/grub.cfg

I would try reading the gentoo wiki on Grub2, server seems to be unresponsive at moment but the cached page is still there on google

[donnie]

Yes, its a GRUB2 issue, because there are only 4 things: Sabayon, GRUB2, SRCD, my hands. I will try my best now, just didn't sleep, not because of GRUB, and got that problem in the end

[donnie]

Its for sure a bug in GRUB2. I fixed all error messages. So, partially fixed. Will just add SystemRescueCD menuentry and try boot.

Code: Select all

grub-mkconfig -o /media/sda1/boot/grub/grub.cfg
head: cannot open `/boot/grub/video.lst' for reading: No such file or
directory
Generating grub.cfg ...


Solution (found on Ubuntu forums):

Code: Select all

echo "vbe" >> /boot/grub/video.lst


Code: Select all

grub-mkconfig -o /media/sda1/boot/grub/grub.cfg
Generating grub.cfg ...
/sbin/grub-probe: error: cannot stat `/boot/grub/locale'.
No path or device is specified.


Solution:

Code: Select all

vim /etc/grub.d/00_header
# BUGGY code, don't need locales at all !!
#if [ "x${LANG}" != "xC" ] ; then
#    prepare_grub_to_access_device `${grub_probe} --target=device
${locale_dir}\locale`
#  cat << EOF
#set locale_dir=(\$root)$(make_system_path_relative_to_its_root ${locale_dir})
#set lang=${grub_lang}
#insmod gettext
#EOF
#fi


Now working with no errors:

Code: Select all

grub-mkconfig -o /media/sda1/boot/grub.cfg
Generating grub.cfg ...
Found background image: media_life_800x600.png

Found initrd image: /boot/initramfs-genkernel-x86-2.6.33-sabayon
done


Here is how GRUB2 installed from the beginning:

Code: Select all

rm -rf /media/sda1/*
grub2-install --root-directory=/media/sda1 /dev/sda
grub-mkconfig -o /media/sda1/boot/grub/grub.cfg


Now customizable

It seems a script generating grub.cfg, in this new version of GRUB2 is executed during a boot. That's why I can only customize boot menu, but cannot effectively add menu entries. They can appear in grub.cfg, but even if I manually add menu entry to grub.cfg sections, they does not appear. Now I rebooted, and see all manual changes to grub.cfg gone.

Theme renamed to: Cannot add custom menu entry to GRUB2 bootloader

Now I know, why I couldn't create menu entries for GRUB2:

Looks good

A problem with booting .iso image of SystemRescueCD (and possibly other iso-s?) from GRUB2, have no known solution for now:

http://www.sysresccd.org/forums/viewtop ... 5&start=30

[EDIT] Clonezilla was able to boot from .iso too (didn't try it myself though), does not boot with the same messages:

error: cannon read the Linux header.
error: you need to load the kernel first.

[donnie]

Here is solution that works, PartedMagic and Clonezilla:

Solved because im not GRUB dev and tired. This way all works much much better, I win
