This generally means that the system cannot find your initrd

In your case, if I read correctly your /boot is /dev/sda1 but you have 
designated /dev/sda2 as 'root'... I think you are confusing grub's 
'root' with the linux 'root' or '/'. Grub's root is where the kernel 
image and initrd image are located, which is at /dev/sda1.

Try changing the root=/dev/sda2 to root=/dev/sda1 and see what happens.

Then, jump over to kernel.org and read the how-to on kernel rebuilding. 
Even if you have no intention of doing that it helps to understand how 
the process works, especially if you need to make an initrd image, which 
is sometimes needed.

And no I am not an expert either, but I do try to remember my mistakes! 
Been there, done that, no t-shirt. no burns or scars.
