Manual Grub Entry

[_Mark_]

Hi
I have added a manual entry to /etc/grub.d/40_custom and ran update-grub and the entry is added to /boot/grub/grub.cfg OK

But when booting the entry is not appearing

Has anyone come across this before as am a bit stumped trouble shooting this as there are no errors

Thanks

Have a look at item number 14 in this guide by drs305, just to check what you've done

Ye I have I looked at this thread by the same person http://ubuntuforums.org/showthread.php?t=1195275

Basically add the entry, update-grub and voila, to be honest I'm not sure the entry is 100% correct but that shouldn't stop it appearing especially as it is written to grub.cfg correctly

Weird

I haven't done this addition myself, but I would imagine that the entry has to EXACTLY match what drs305 quotes (except for the different drive/partition number) for it to work.

Is it possible that you have more than one linux with more than one grub2 and you are trying to edit the wrong one, ie a grub2 menu that is actually from a different OS to the one you are editing?

It should be obvious, I agree, as the default OS to which the system boots will be the OS that has the active grub2 configuration files.

An excellent point! I have fallen foul of that myself

It does see below the contents of 40_custom

#!/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.

menuentry "Wary (on sdb1)"{ 
set root=(hd1,1) 
linux /vmlinuz pmedia=usbhd
initrd /initrd.gz 
} 
EOF

and here is the entry in grub.cfg

### BEGIN /etc/grub.d/40_custom ###
# 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.

menuentry "Wary (on sdb1)"{ 
set root=(hd1,1) 
linux /vmlinuz pmedia=usbhd
initrd /initrd.gz 
} 
EOF

As I said the entry may not be 100% correct but that shouldn't stop it appearing on boot should it?

Thanks for the idea I do have several partitions with another *nix but I have double checked and I am using the correct grub
Edit:
the only complication is it is on a USB HD but again I can't see that stopping it appearing

If you have lots of systems & then lots of entries in grub's menu, you can have more entires than the display box can show. If there is a tiny arrow on the right side it means there are more entries and you have to scroll down to see the last one's.

I only have about 8 entries it's definitely not hiding but thanks for the reply

I even renamed it to 06_custom so it should be at the top but no dice
