Technically (theoretically) speaking, using a Win32 boot disk to fdisk
/mbr, he should be able to re-initialize the FBSD boot loader by going
through the steps he did initially.

AFAIR, Symantec GoBack, along with many other 'in-disk' restoration
programs, overwrite the boot sector with its own code.

If the OP can boot back into Windows with the fdisk /mbr, he has likely
done both:

- broke his GoBack program's ability to recover, and;
- made it possible to restore the FBSD boot manager

If Windows boots after following Kurt's recommendation of restoring the
Windows MBR, back up your Windows system, then try FreeBSD again.

You sound courageous, give 'er!
