Setting up Grub to multiboot

flux9842 · 06-01-2011, 11:42 PM

I am a new user of Ubuntu and I am having problems setting up GRUB to multiboot Windows 7, Windows Vista, and Ubuntu 11.04. Following this guide http://erickoo.wordpress.com/2009/06...-karmic-koala/

I got to the point where I need to save the file called '11_Windows' However, in the terminal after trying to save it. (ctrl + x, yes to the save dialogue, then pressing enter) I come across an error that says ' [ Error writing /ect/grub.d/11_Windows: No such file or directory ] '

I have spent about an hour trying to find round about ways to create/ save this file and none of them have worked. If someone could tell me what I am doing wrong or what I need to do, it would be greatly appreciated.

That would be /etc/grub.d/...
With current versions of Ubuntu, a simple "update-grub" should do all that for you.

What's the problem ?.

The first thing you should do after installing Ubuntu is to run:

Code:

sudo update-grub

Hopefully, this will add Windows 7 and Vista to your /boot/grub/grub.cfg file so you can boot into Windows.
If that does not help, see this tutorial for creating custom boot entries in the /etc/grub.d/ directory in grub2: https://help.ubuntu.com/community/Gr...Menu%20Entries
NOTE: I have never needed to use the first 2 lines:

Code:

#!/bin/sh
exec tail -n +3 $0

in any of my custom boot entries for grub2. However, I have seen other people report that their custom boot entries did not work unless they had those 2 lines at the beginning of their custom boot file. So try it with them.
For reference, here is the custom boot file that I used for booting WindowsXP on /dev/sda1:

Code:

echo "Adding WindowsXP on /dev/sda1" >&2
cat << EOF
menuentry "WindowsXP on /dev/sda1" {
        set root=(hd0,1)
        chainloader +1
}
EOF

Write back if you need more help. Also post the output of

Code:

sudo fdisk -l

so we can see where your operating systems are installed to which partitions.
