No joy. I checked all ufs partitions and none are "root" except for /dev/ada1p2. All partitions on ada0 are ntfs. (It's my Windows disk.) But, thanks for trying, Warren. I appreciate it. -- R.

Well, the fact that it has a ufs label, fstab show ufs and fsck runs fsck_ufs are strong hints. 2.

Removing UFS label from root
I added a label to my root fs some time ago. I really prefer the gpt label and I have added it, but I can't figure out how to remove the ufs label. I boot single user and run 'tunefs -L "" /dev/ada1p2' but I get an "unable to write superblock" error. This is before mounting the drive RW, but it is, of course, mounted RO. I tried setting the "allow foot-shooting" debug flag, but it did not help. Is my only hope to boot a live system? (I have no CD, so I guess I could try a a thumb drive.) -- R.
