Howdy,

I have my Acer Revo setup to dual boot with Windblowz 7.
When the machine boots and grub comes up I have an entrie I want to change, just the description.
It is for the 1GB recover partition, all I want to do is change it's description and move the entry to the last.

There is 3 entries the 1st being for Bodhi, the 2nd is for the 1GB Revo/windows recovery partion the 3rd is for the Windowz 7 os.
What I want to do is put the 2nd entry at the bottom and make the 3rd the second selection in the list.
I can post my Grub list if I could find it but I can't remember where it is.
Cheers
Jr223

You can easily post that file. In terminal:

cat /boot/grub/grub.cfg

Just copy and paste it here and w'll tell you the best options.

Change it to:

menuentry "Windows 7 (loader) (on /dev/sda2)" {
	insmod ntfs

I had to reinstall bodhi 1 week ago. afer this , there was bodhi linux in grub.
but 1st problem was there.

Today I tried to add connochaet but failed. I had to use live cd & boot-repair-ubuntu.

for grub correction , I used all steps described in earlier thread. but sudo update-grub is failing..

[Charles@Bodhi]

@Rohit
To fix your error please replace the file /etc/default/grub with the same file from a live CD, because it seems to be corrupted.
After doing so check it by doing a update-grub.

Your file /etc/grub.d/20_memtest86+ also is corrupted because it has the connochaet entries which should not be there. You better replace that as well with a original one.

The place to create the entries for connochaet is the file /etc/grub.d/40_custom
Open it in leafpad with gksudo and you can edit it to look like this:

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

initrd /boot/kernel26-libre-lts-fallback.img
}

NOTE: There should be an empty line at the end!

The words between " " (which I slightly altered) will be displayed (NOT ' single quote signs ') The boot info I have copied from your post, so they should be fine.
Save the file and do update-grub and see how your /boot/grub/grub.cfg looks.

Tip: If you want the Memtest to be on the bottom of your grub screen then rename the file /etc/grub.d/20_memtest86+ into /etc/grub.d/49_memtest86+

Hope this helps.
Charles.

OK, I see what is going on. Grub2 cannot boot Connochaet directly. So we have to chainload it to your older Grub on sda7.
Lets modify your /etc/grub.d/40_custom again to look like this:

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
#
# Entry for another bootloader
#
menuentry "Grub on ConnochaetOS" {
set root=(hd0,7)
chainloader +1
}

Again make sure the file ends with a blank line. You can put what you want between the " " in the custom file.
Now run update-grub and check your /boot/grub/grub.cfg
If that looks OK you can reboot and try if it works to go to ConnochaetOS.
Good luck,
Charles.

@Rohit
You need to drivemap.....


menuentry "ConnochaetOS" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos7)'
search --no-floppy --fs-uuid --set=root f5594706-50c4-4de8-9093-cad03af2c8b1
drivemap -s (hd0) ${root}
chainloader +1
}

ps: you're not the OP. Is OP's problem solved?

Oops. Bodhi uses grub 1.98 not 1.99....
Correct

I changed it to

menuentry "Grub on ConnochaetOS" {
set root=(hd0,7)
linux /boot/vmlinuz26-libre-lts root=/dev/disk/by-uuid/f5594706-50c4-4de8-9093-cad03af2c8b1 rootflags= rootfstype=ext4 ro
initrd /boot/kernel26-libre-lts.img
}



Thanks ! Now it works ..
