RPI root partition lost PARTUUID and can't boot

So I cloned a RPI sd card so I could run the same system at home and at work. The sd cards were slightly different sizes so after I ran dd I had to run resize2fs and fsck. If I boot the Pi with this I get dropped to an emergency shell and I can mount the root partition and it works.

The problem: I need this to run headless and I cant mount the root partition every time it starts. When the Pi boots it looks for PARTUUID="ceafa322-02". If I could change the pi to boot from the new root UUID or something that would be fine, but I don't know the boot process on one of these. What I have been trying to do is modify the partition with fdisk, but I dont know how an identifier like 0xXXXXXXXX translates to ceafa322-02 as a PARTUUID

What is the best course of action? I can nuke the installment, but I am almost determined at this point.
