David is not saying that dual-booting does not work. He is saying that the sysinstall step can get in your way, depending on how you try to create the two systems you want to boot between. Once you GET the slices and partitions set up right, then the booting process can easily handle multiple freebsd systems on a single disk. For instance, in the following sequence you should not run into any trouble with sysinstall: first set up a dual-boot system with the first dos-style slice being Windows, and the second one holding freebsd. after running this way for awhile, you decide that you do not need windows any more. So you again boot off the FreeBSD cd, you blow away Windows, and you install a second snapshot of freebsd on the slice which used to be Windows. For both of those freebsd installs, at the time of the install the first slice on the disk which was of type freebsd was also the slice that you wanted root (the '/' partition) of the new installation to be on. So, sysinstall has no trouble with what you want to do. Where you have trouble is if you have two dos-style slices defined, both of type freebsd, and you want sysinstall to install into the second of those two slices. -- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
