It sounds as if the kernel updates did not complete properly.

What versions of grub do you have on the sytems?
https://help.ubuntu.com/community/Grub2
https://wiki.ubuntu.com/Grub2

On 1, is it freezing, or are you able to edit?
On 2, try the recovery mode and select the dpkg/'Repair broken packages'
fix. Afterwards, also run the grub/'Update grub bootloader'.
