Hello all. I hope I have posted in the correct forum. I have a triple boot setup with Windows 7, Backtrack5 R2 and Knoppix. While Knoppix has, for the most part, been a swell distro, it's also a security hole in my machine due to the lack of any login screen or password requirements. I want to replace Knoppix with Debian 6.0.5.

My problem is that I'm not sure how to install Debian without Installing Grub that comes with it, then edit the BT5 grub menu to reflect the new OS list after the Debian install.

Does anyone have an idea as to how to go about this?

Bt5 is debian based you should be able to do & automatically detect debian.

BT5 is Ubuntu based, not Debian based.

To answer the OP's question: Just download a Debian installer CD (not a Live-CD) and during boot choose the expert install option. This way you should be asked if you want to install a bootloader.
After installation boot into Backtrack and launch , which, as EDDY1 stated already, will add debian to the boot menu.

Excellent. I will try this and report back on the outcome. Many thanks!

Hmmm. The terminal is telling me that Grub is not installed nor is the 'update' command....

and return the following messages;

and

The bootloader does say 'Grub'.....What is going on here?

That is because the command is

I forgot the "-" on 'update-grub'. :/

Well, It worked without a hitch. The only problem was that the particular version of Debian that I have does not have wireless drivers for my netbook

Thank you for your help

Open a new thread for your wireless issue, I am sure that there is a solution.
