No /boot/loader

[Amarendra Godbole]

Hi,

I installed FreeBSD 7.0-current snapshot [200710] on my laptop. I have
two issues,
of which second is major:
1. It could not find any X filesets
2. After rebooting, it tells me something like "No /boot/loader", and
does not boot.

I tried to google for #2, but found no solution. I am surely making a
mistake somewhere,
but am unable to figure out. Any help regarding this is much
appreciated. Thanks!

This laptop already had a FreeBSD slice, so I did no create new
partitions inside it,
but just mounted and formatted the existing ones.
