IIRC, the package should be in the directory above your current 
directory. But shouldn't the package name be "linux-image-something"?

Go to the directory where you compiled your custom kernel and copy 
"arch/x86/boot/bzImage" to "/boot/vmlinuz-your-kernel-name", copy  
"" to "/boot/" and copy ".config" 
to "/boot/config-your-kernel-name". Then run the command

sudo update-initramfs -c -k your-kernel-name
sudo update-grub

Replace "your-kernel-name" above with the actual kernel version.
