I tried to update my kernel in Ubuntu and booting into it does not work. I can still boot with my old kernel by going into advanced boot options and selecting the previous kernel but I would like to get 4.7 working.

The error message is something about a working init not being found and it is asking for an init= to be set in the boot options.

I have no idea what is going on here. Can someone help?

We need the exact error message. We can assist you by using the output to search how others with a similar issue has been resolved. – L. D. James Sep 25 '16 at 23:43

The clue is in line "Starting init: /bin/sh exists but couldn't execute it (error -8)"

A check in errno.h says the 8 is "Exec format error".

Are you trying to run a 32 bit kernel on a filesystem with 64 bit userspace?

I am much dumber than you estimate. How do I find out if this is my mistake? – MindlessMutagen Sep 26 '16 at 0:24
    
@MindlessMutagen Tell us which kernel you downloaded, the one ending in amd64.deb (64 bit) or the one ending in i386 .deb(the 32 bit). – WinEunuuchs2Unix Sep 26 '16 at 0:32
    
Additionally please update your question with the output of uname -a – WinEunuuchs2Unix Sep 26 '16 at 0:40
    
I am a moron who downloaded the i386 kernel. You have been greatly helpful but I still feel like a moron. Thanks – MindlessMutagen Sep 26 '16 at 0:44
    
We all make computer mistakes, indeed those who use it the most probably make the most. – WinEunuuchs2Unix Sep 26 '16 at 0:54
