The whole point of my question was to install FreeBSD/ZFS as a second
system to a box where Windows/NTFS already occupies one MBR partition and
there is another MBR partition for FreeBSD. Do you think there is no

"Will not boot"? That is odd because:

1. That's basically the setup Manish suggested (using ada0s3a for
zpool), and I think it works for him if he gave this advice.

2. zfsboot(8) is designed for MBR so why would it fail to boot?

But your setup is not dualboot which I was asking about.
