You're consistently typing udb2 instead of ubd2 (note the exchange of 
letters). That's your error, unless it's only in the mail.

No, you shouldn't. But that's unrelated.

It can't open the rootfs you indicated to it and is complaining for that. 
That's unrelated to fdisk.

There's no problem with the ISO, assuming you've compiled in iso9660.

I'm not sure whether, after using ubd (not udb, uBD), that would work.
I use the syntax rootfs=/dev/ubda, which for your case would become 
rootfs=/dev/ubdc.
