EasyBCD works with 7 too, but maybe you have XP?
If so the FreeBSD boot manager works quite well for dual booting.

I don't know how to use the install DVD to boot an existing install,
but I think you can use it to chroot in. It's been awhile since I did
it, but I do remember it's not at all hard if you have the livefs
install CD. In fact, ISTR that once you select the livefs option from
sysinstall one of the options is "rescue", and you can select your
root partition and all that. I'm not at home right now, or I'd pop in
the CD and look it up but I'm pretty sure you'll be able to fugure it
out easily, but you may need the livefs CD rather than the DVD installer.

Well, I did try it just now.... Everything worked great, until the boot.
Then I ended up right back at the mountroot> prompt...same error. I did
notice one thing, though: the boot messages did NOT show the error about
waiting for the usb bus ... and it DID load the kernel from the usb
drive...still didn't find root. It said to remove any errors in
/etc/fstab ... but I checked, and didn't find any (nor would I expect to
immediately after a fresh install).

Something very, very odd is going on here....

Thanks,

You are welcome.

AFAIK the USB timing issues are only present in 8.X.

A new USB stack is the default in 8.X, and there are a few "interesting"
interactions between device discovery and the root mounting code.

Ceri Davies' guide is better than my usual "copy everything over" trick
for new, clean installations.

Both install methods have their merits and their faults, though. For
example, my tar-based approach might copy stuff to the USB stick that
shouldn't be there. But it's *very* fast if all you want is to save a
usable copy of a system, e.g. for recovery purposes. Much faster than
going through the steps of re-configuring everything on a clean install.

This sounds like a bug. You should probably describe the setup at the
freebsd-current mailing list and see if someone more knowledgeable about
the zfs internals has done something similar.

No, I'm afraid not :-(

Windows and even some BIOS revisions in relatively 'modern' laptops has
been known to have issues with the MBR boot0 code of FreeBSD. I usually
avoid multi-boot installs for this reason and try to use /boot/mbr as my
boot0 stage code instead of the menu-based boot0 code.

You can install boot code to the MBR of any disk with boot0cfg, e.g.:

boot0cfg -v B /dev/ad0

Install the default /boot/boot0 code to the MBR of ad0.

boot0cfg -v -B -b /boot/mbr /dev/ad0

Install the /boot/mbr boot code to the MBR of ad0.

Note: The /boot/mbr code is a simple, quite 'plain' version of an MBR
loader, that simply boots the first active partition of a disk. No
menus, far less compatibility problems with crafty BIOS firmware code,
but also no means of switching to another disk or to PXE boot.
