BTX Halted (Reinstall Boot Loader Only)

[AlbyVA]

I got the error message during a reboot of my FreeBSD box that says BTX halted. My assumption is the the boot loader got corrupted.

So my theoretical solution is to replace/reinstall the boot loader. I have a boot only CD that I've burned. So I can boot to the live disk or shell and do whatever is needed to reinstall a new boot loader on my hard drive. Question is, how do I reinstall the boot loader on the HDD from the CD?

Thanks.

You can use the gpart bootcode command. You just have to make sure you are referencing the correct drive and partition.

Got a sample command line on using gpart bootcode to accomplish such a task?

For installing/replacing the MBR bootcode it goes like:

gpart bootcode -b /boot/mbr ada0

If it's GPT: gpart bootcode -p /boot/gptboot -i 1 ada0
