Re: Booting more than 4 OSes from a hard disk?
Master boot records are limited to four which is where the limit comes from. It is theoretically possible to have the MBR point to a new disk location where you could have a boot manager that supports unlimited boot partitions. But that requires all the booting is in software and outside the BIOS. A simple solution is to use 2 disks. Each with four partitions. The FreeBSD bootmanager will offer to boot from disk2. On disk 2 you can have your remaining OS's. -Derek At 10:40 AM 8/8/2006, Girish Venkatachalam wrote: Dear all, I was wondering if the 4 primary parition booting limit still exists.

Re: Booting more than 4 OSes from a hard disk?
Windows 2000+ can boot on an extended partition as can linux, the BSDs, I think OS/2 warp+ can as well. So you can still only have 4 primary partitions, but you probably only need one that has a bootloader like GRUB on it marked active and the OSs installed all on extended partitions. I've even supprisingly confirmed if GRUB is installed windows won't install it's own bootloader. At least with Win2000sp4 this was the case the one time I tried... I would use GRUB cause its simple, fits on a floppy and is easy to install from that booting floppy. It shouldn't require any special booting options other then boot from harddrive. I would guess BSD doesn't care where it boots from in terms of sectors on the HD, but making a bootloader do this is something I wouldn't be able to answer. Although I know Grub allows you to chainload an arbritary number of sectors from the bootsector so I would look into that for exotic boots as you allude too. -brian --- Girish Venkatachalam <[EMAIL PROTECTED]> wrote: > Dear all, > > I was wondering if the 4 primary parition booting > limit still exists.
