I had a win 7 (32 bit) on dell vostro 1500(T9300cpu). Now I installed natty and restart but no grub were displayed.

I give 8Gb to root and 2Gb to swap and about 8.5Gb to home section. Root and home are ext4 partition format.

What's the problem? How can I fix it?

Do you remember where you installed GRUB? Was it to the MBR? –  boehj Apr 28 '11 at 20:54

I installed Natty onto a separate drive than Windows 7 (a USB hard-drive that I had been using for backup), and when I reboot there is no GRUB. But when I choose boot options (on my Dell I press F12 during boot), then I can choose either my internal hard-drive or my USB hard-drive (amongst other options, of course); when I choose to boot to my USB hard-drive, I get GRUB!

Perhaps if you installed Natty onto a different drive that Windows, you might need to choose that drive and THEN Natty, just as I do.

Try editing the main GRUB configuration file (/etc/default/grub) and changing GRUB_TIMEOUT to a different value.

One way to edit the file is to run:

gksu gedit /etc/default/grub

You can also try tapping or holding up/down keys right before Ubuntu starts up.

After ObsessiveFOSS advice:

From this link...

Step 1: Boot from the ubuntu live cd and go to terminal

Type in terminal:

sudo grub
grub> find /boot/grub/stage1

That should return your Ubuntu partition in the form of (hdX,Y), use that:

grub> root (hdX,Y)
grub> setup (hd0)
grub> quit

(You don’t need to type the grub> part.)

That has re-installed grub but you can no longer see Windows 7.

Step 2. Edit the main GRUB configuration file.

Boot into Ubuntu, open a Terminal, and type:

gksu gedit /boot/grub/menu.lst

A large text file will open and at the bottom leave a line and add this:

title    windows 7 beta (Loader)
root     (hd0,1)
savedefault
makeactive
chainloader +1

(Do not type this line but if that does not work on re-boot try “hdo,0 or hd0,2” and so on until it works.)

Now that is done you can re-boot into Windows 7 and Ubuntu.
