How is it possible to boot XP from a logical partition?

mmm... Not using any add-in boot-manager utils, you can install the actual OS itself - its system folders/files - to a logical drive..., but the actual boot/start-up files "must" be in the active Primary partition... The ARC/path-statement will point to the correct location of the ntldr etc. and thus boot the OS (XP - or W2K/NT) that is installed in other than the active Primary... I have a feeling that even using a decent boot-util the same condition applies. The only difference being that the boot-util slips itself into the active Primary etc., replaces the NT style boot-menu and efffectively controls what boots and how... (But it's been an age since I use one so I may be a little out here with regard to what current boot-utils allow?) If you're really asking "how to set up a dual/multi-boot" - perhaps post back? There are several approaches - with/without boot-utils; and it's a matter of personal preference as to how you go about it overall...

I use lilo to boot other OSes, but I don't want Windows to take up one of the four primary partitions. I put it on a logical partition, but was not able to boot it with lilo as far as I can remember.
