There's no such thing as "minor things" when it comes to filesystem  
corruption, especially when it results from a power loss.

Your filesystem suffered unknown corruption and damage. The list of possible  
reasons why the system fails to boots is an infinite list.

Your only realistic option for you is to boot from a live image, mount the  
partitions, copy whatever files you find, and need, to a USB stick, then  
reformat and reinstall from scratch.

Don't be surprised if you find that some of the files are bad, and are  
filled in whole or in part with random binary garbage. Take that  
observation, apply it to the kernel, the ramdisk, and everything you find  
in /bin and lib(64)?, and you pretty much have a good idea of what's  
happening.

When things are back to normal, consider investing in a UPS, that will give  
your systems time to shut down normally in the event of a power loss.
