Grub 2 - Windows 7

[Cole]

I have not used Ubuntu since 7.10--so Grub 2 is particularly new for me and as such I am sort of lost.

I installed the Ubuntu partitions manually by resizing my main partition and creating a swap and ext4 partition in the new free space. Both my Windows 7 boot partition and the main (C:) partition are still in tact and there has been no data loss.

Grub2, however, did not automatically add Windows 7. I have no idea how to work with its syntax and I am also not very sure if grub handles Windows 7 differently than previous windows releases.

Could anyone tell me how to manually or automatically add my windows 7 partition?

Thanks!

$ sudo update-grub

I would run in terminal from 9.10 sudo update-grub as requested by SlonUA.

Reboot and if windows still is not in the GRUB menu do this:

Let's get a better look at your setup & boot process. Boot into Ubuntu. Come back here and use the link in my signature to download the Boot Info Script to the desktop. Once on desktop open a terminal (Applications > Accessories > Terminal) and run this command

sudo bash ~/Desktop/boot_info_script*.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

When you run update-grub in a terminal, it will report back on every OS (and kernel) it finds, one row at a time. You should see it report on finding Windows 7, although it might say Windows OS Loader.

Having the same problem here, after a kernel upgrade to 2.6.31-19...

I'v been using 9.10 for a while and after a kernel upgrade it seems that the upgrade-grub script doesn't run the /etc/grub.d/30_os-prober and so it doesn't find oter OSses...

And upgrade-grub insists in generating menu.lst that I would think it's no longer necessary with grub2.

I need to see what you have on that machine. Do this:

Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and do the following:

1. Download the boot info script. There is link in my signature.
2. Once downloaded move the boot info script to the desktop.
3. Open a terminal and run the command

sudo bash ~/Desktop/boot_info_script*.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

See here for more info on the boot info script.

Presence's script will show us what you have -- but if I had to guess, I would say you updated from 9.04 to 9.10 because that will not automatically install GRUB2 and running update-grub will simply rewrite the legacy menu.lst file.

[kansasnoob]

In deed run the Boot Info Script and post those results here. To be sure you don't have a "mixed bag" of legacy grub and grub2 files it would also help to see the output of:

grub-install -v

ls /boot/grub
