Hi all. Thanks for the replies Lorenzo and Mat, I will finish the Debian install on my friend's box tomorrow in that case. Just a question though. As far as I know, according to a normal boot process the Bios first checks for the presence of any other boot media, and then executes the boot loader which reads the Mbr. If I were to overwrite the mbr, wouldn't the nt loader have a fit because its mbr is nowhere to be found? Or would the presence of the nt loader go away entirely? I am just asking because as far as I have known an MBR is supposed to be contained on Secrot 0 of the hard disk. Since an operating system is being installed to somewhere around cylinder 2131, I was just curious as to how Lilo would access the existing MBR to overwrite it?
