If you have physical access to a linux computer, chances are the only thing you'll have to do is enter init=/bin/bash rw in the Lilo prompt after the selected kernel image..
9 out of 10 standard installations will geve you root access
Using buffer overflows etc only works on "services" the computer is provinding (like http, ftp, ssh)..

More on prevention of lilo misuse can be found here: http://printf.nl/?lilo+root
Yes, it's possible to use loadlin.exe for that..
But won't work (good/at all) with NTFS..
You do need to copy your vmlinuz (kernel image) to the windows partition and setup the NTLDR to start loadlin.exe..
I havn't done this on NT (just win98 years ago)..
And I won't recommend using loadlin !

nah, there's a better way
Jinxy (and ash) there's an easier way to dual boot and launch linux from the windows loader. I keep saying Imma write a tut, but haven't gotten around to it. Here's the extremely abbreviated version.
You will need:
1 computer (with floppy drive)
1 windows installation on computer
1 linux install media
Setup windows to run normally. leave a partition big enough for the linux install.
Install linux on the extra partition(s). Make sure you have the install process create a boot floppy, or this get's a LOT harder for the newbie/non-experienced. Make sure linux installs grub/lilo at the beggining of the linux partion, not the MBR or Superblock.
Boot linux (via floppy) and login. Use the dd command to create a file from the first sector of the Linux partition (this is where the grub thingy (Binary? Loader?) is located).
Copy the file you just created to the Windows partition (probably by putting it on a floppy). I usually name it linuxldr.bin
Boot to windows and edit your boot.ini to include a new line. The line should look like this:
Code:
C:\linuxldr.bin="Red Hat Enterprise Linux 3"
If I haven't forgotten anything, this will make your system boot to the Windows 'Choose your operating system' screen, and if you select the Linux, it will then launch the Grub interface you're used to.
Like I said, I'll write a formal tutorial with screen shots and verified commands soon.

Hmm, I was just asked about movies and cracking, and if it is real or not.
Movies are just that, movies and are usually not real.

I can personally attest that they modeled the hacker-guy from Swordfish after my own abilities. Only they had to slow down the cracking times to make it easier to see and understand in the movie.
really. it's true.
they found me after my picture was taken standing on top of Building 1 of the Twin Towers, with the planes approaching in the background. terrible day that was. but it's quite a picture.

Oh so you're the one who can't hold it in for more than 60 seconds because of some girl huh? Nice one. Didn't you play in another movie? Gone in 60 seconds? Which was modeled after your hold it back abilities?

Dual booting so that NT Bootloader has control isn't new:
Source 1
Source 2
Source 3
9 out of 10 standard installations will geve you root access
Is this still true? This is a basic security "feature" that I thought was being removed from most of the Linuxes and that default boot security was being put in place to prevent access to single-user mode.

DOH! Good one! Guess I asked for that.
Actually, the 'holding it in' was modeled after you. I was referring to the 'crack this 65536bit hashed password by hand in under 60 seconds' bit. That's all me. :P
Back to reality, folks.
