I use ubuntu a lot but had to install windows. Now I have no grub menu and windows automatically installs. Is there an easy way to fix this problem and restore grub?

yes you need to download the super grub boot disk to reinstall grub.

when you installed windows, it overwrote grub with the windows MBR...

If you reinstall grub it will allow you to select either windows or ubuntu upon boot time.

I believe you can use the Alternate disc and skip to the end to install GRUB

Boot off your Ubuntu LiveCD and run

sudo grub
Then,


root (hd0,?) (? being where your controlling distro is)
setup (hd0)
quit


Also, 5 seconds in google: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows

I would go with the live cd solution. To find out which partition your ubuntu install is in, type:

sudo grub

find /boot/grub/stage1

I used the super grub boot disc and got ubuntu running again. Now xp doesn't show up on grub. Any ideas on how to get it on grub?

Run ubuntu and open the file /boot/grub/menu.lst, and post the contents here. Also, post what typing:

sudo fdisk -l
in a terminal returns.

Through those two pieces of information, I'll be able to find what your grub menu looks like, and also which partition windows is in.

Press alt+f2 and then type:
gksudo gedit /boot/grub/menu.lst

Add this to the end of the file:


# This is a divider, added to separate the menu items below from the Debian
# ones.
title Other operating systems:
root


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title Microsoft Windows
root (hd0,1)
savedefault
makeactive
chainloader +1

Then save the file. That should fix it!
