Invalid Partition - help on setting up loader

[Joseph]

Hi list. Merry Christmas!!

This is my first post on a Freebsd Mailing List, so don't be too harsh on me if my ettiquette isn't acceptable.

Ok, I guess I'll get to the heart of this post:

I'm trying to figure out how to boot 5-releng-1 alongside my 4-stable slice.

After a surprisingly successful buildworld/kernel, installworld, I used /stand/sysinstall to fdisk/disklabel the appropriate partitions. By the way, both slices exist on the same disk.

Booting to stable was fine, however, booting to current gave me:

invalid partion

I was, however, able to get it to work, when I pointed the boot to 0:ad(2,e)/boot/loader (which is the location of my current's root partition.)

I'm happy with how my current installation went, but I may have missed a crucial step along the way.

Any advice welcome

[edit] I was referred here from the newbies list. Go figure.
        If this isn't a newb question, what is?
