You will need GRUB no matter what (I think), but you do have a choice about where and how to install it. Normally, you'd install Ubuntu after Windows 7 and GRUB would be written "on top of" the Windows boot loader. When you boot up, GRUB would load and you'd then pick Windows or Ubuntu.

But...if you use something like EasyBCD, you can install GRUB in the Ubuntu partition and use EasyBCD to modify the Windows bootloader to give you the choice of booting Windows or Ubuntu.

I've done it a time or two, and it works fine but I don't remember the specifics. Google up EasyBCD and check out their forums and how-to's to get a walkthrough on this.

Edit: I should have read the post title more carefully, but EasyBCD should still work...

Its going to be hard to find this feature

Micrisoft doesn't have the need to add this to their bootloader after all. I posted the idea of adding Grub installer to WUBI too install Grub on a Windows session send me a PM if you want to see it.

Thanks for this solution, however it did not help my situation as windows was kind enough to rewrite the mbr on my laptop when it went into hibernate. This laptop does not have a working cd drive, thus is unable boot from a livecd.

Another solution I found is to use ntldr and load a version of grub from there (grub4dos). I think it would be a good idea to provide instructions for people on how to achieve this using ntldr and grldr.

The only caveat with having a setup like this is that you will need to copy menu.lst that grub uses to the default windows partition everytime you perform an system update (otherwise it wont load the latest kernel).

I have setup my laptop to use this method. First I added the line:

C:\grldr=”GRUB Bootloader” to windows’s boot.ini

I copied the file grldr from grub4dos to C:\

Using ext2ifs on windows I copied the menu.lst from /boot/grub to C:\ on my windows install.

After rebooting, I had a working install of GRUB. This didn’t require me to rewrite the mbr of my hard drive.

Can I use Grub4Dos then to install Grub?
