I am using the Debian lilo in MBR to select which os I
should boot.
Initially was:
ad0s1 XP * marked as bootable
ad0s2Swap Debian
Debian /
FreeBSD (swap, /) * marked as bootable
Everything was fine. I needed space for FreeBSD, so
went into /stand/sysinstall and delete XP; recreate a
new FreeBSD slice, press W to save it into MBR, forgot
the pesky "bootable" flag, return to FreeBSD, and
before creating any partition in the new FreeBSD
slice, now first, I rebooted.
In MBR I had:
FreeBSD (no slices) * marked as bootable
Swap Debian
Debian /
FreeBSD (swap, /) * marked as bootable
In this moment, the FreeBSD doesn't boot anymore. From
fixit/live cd, I reset the bootable flag for first
slice and the system booted finely well.
I was hoping that I can specify in the boot2 prompt
the correct partition, on ad0s4
