Loop reboot, how to bypass it to reedit a file.

M

MrNoob

FreeBSD 10.2 got into looting loop after a successful updates and ports upgrades.
Also x11/gnome3 was installed successfully.
However after an attempt to get the Broadband wireless model BMC4321 to work i tried to install the driver bwn(4). Because i did not do such things before, i tried to add

Code: 
if_bwn_load="YES"
to /boot/loader.conf , which was empty.
And then booting leads only to another booting. How could i remove the line I have added to the file?
The PC is a Lenovo Ideapad S10-2, if that is relevant anyhow.
Please I need your help. Cheers!
 
In a similar situation, I had to boot from an installation disk (a bootable USB disk does the trick for you), mount the root partition, and edit the loader.conf. You may need to use gpart list to get the device name of your hard disk.

Refer section 2.3.1 in the Handbook to see how you can prepare a bootable USB disk.
 
You can always drop to the loader(8) prompt when the loader screen appears. It should be selection number 3 on the 10.2 loader screen. At the prompt you can then unset the if_bwn_load variable and boot without the setting:

Code: 
unset if_bwn_load<enter>
boot<enter>
