Default [Solved] Laptop won't boot after crash.
I have successfully installed PCBSD 9 an a Compaq Presario CQ61.
Yesterday I have loaded the acpi_video.ko for adjusting the LCD luminosity, but when I unloaded it the OS has crashed.
Now the system boots with the "Welcome to PC-BSD!" text menu. After booting it stops to the prompt: mountroot>

How to solve the problem ?

Thanks in advance

I have used mfsBDS CD, http://mfsbsd.vx.sk/, to boot the laptop and login as root, password mfsroot.

Mounted the boot partition:
mfsbsd# mount /dev/label/boot0 /mnt

I have lost the /boot/loadeer.conf file, but fortunately I have a copy named loader.conf.orig.
mfsbsd# cp /mnt/boot/loader.conf.orig /mnt/boot/loader.conf

and rebooted the system
mfsbsd# shutdown -r now

Now all works.

I have done a backup copy of the /boot directory in my home directory.
Booting with the mfsBSD CD, the command:
mfsbsd# zpool import tank0
will mounts the HD tank0/usr in /usr and tank0/var in /var directory.
And the command
#mount /dev/label/boot0 /mnt
mounts the HD boot partition.
Doing so I can restore the boot partition from the copy in my home directory.

PC-BSD won't alter anything in Windows.
