Installed Ubuntu need help booting to windows 7

run:

sudo apt-get -y install os-prober; sudo os-prober; sudo update-grub

May help

I did this, and still have only 4 boot options,, 2 for Linux and 2 for memory checking, does it matter that i partitioned a portion of the hard drive for linux specially?

I noticed windows 7 listed this time, hope this is helping

I just rebooted and now have a new option, chainlink into grub 2
but doing so gives me and Error Code 11

You could try to reinstall Grub:
    https://help.ubuntu.com/community/Grub2#Reinstalling%20from%20LiveCD
So you will have a clean configuration.

I have tried this, windows 7 is still not listed as a bootable option, just the original 4 that I started with

Could you run command:
   os-prober.
If it fails, could you download version 40 of os-prober and install it.
If it fails again, could you provide partition table.

where can i download the os-prober 40, and create the partition table data?

I ran the os-prober that i have and got this?

unshare failed: Operation not permitted
rm: cannot remove `/var/lib/os-prober/labels': Permission denied

sorry ran

Sudo os-prober

and got this result =

/dev/sda1:Windows 7 (loader):Windows:chain

Hope this helps?

Sorry, command is:
    sudo os-prober
To get version 41, go to
   http://packages.debian.org/squeeze/os-prober-udeb

i downloaded what i believe is the correct file but the ubuntu software center isn't giving me a install option, something about invalid archetechture

"/dev/sda1:Windows 7 (loader):Windows:chain" : os-prober detect your Windows installed on sda1, so you don't need version 41 (except if you have two Windows partition and it see only one).
So
   sudo update-grub
should add Windows in Grub menu.
Could you try this command ?

ok i've tried it, and here is the response

Coul you post in paste.ubuntu.com the file /boot/grub/grub.cfg.
I will have a look tomorrow.

done

Thanks

It looks crazy!

Can you run by copy/paste:
   ls -l /boot/grub/grub.cfg ; sudo os-prober ; sudo update-grub ; ls -l /boot/grub/grub.cfg
and copy paste the whole results

Can you run:
   cd /boot/grub ; sudo mv menu.lst menu.old.lst
and then try to reboot.

results from first command

john@Azriall-2:/boot/grub$

I know the list looks crazy but that was installed by Ubuntu live CD i got on the cover of a Linux magazine, no editing, trying a reboot now

No success, still 4 boot options, no windows listed

Hi Guys

Was thinking logicallaly about your advice and came up with a new idea, i have cleared the partition and reinstalled Ubuntu 10.10, but this time i downloaded a 64bit edition not from a cover magazine disc, i did a livecd boot and fresh install, making sure it knew the boot was from windows, this time when i loaded up for the first time i had a 5th option, windows 7! which was sucessful

Thanks for all your help and support, couldn't of done it without you guys and have learn some useful information regarding how to use Ubuntu, i prefer it over windows for speed and stability but i want to hold on to windows for now for my games and to move stuff to my portable hard drive via Mionet

Again my Thanks
