Ubuntu 18.10 boots into initramfs busy shell

I am getting booted into the initramfs shell directly in ubuntu 18.10 I have tried the exit command which leads to the manual fsck is required on /dev/sda2 When I enter fsck /dev/sda2 the shell returns `Either the superblock or the partition table is likely to be corrupt! Abort? keep in mind sudo bash fdiskor any other shell commands return a not found error.
