End kernel panic - not syncing: VFS: Unable to mount root FS on unknown-block(179,2)

Question

My pi-top says this when it tried to boot and I tried the method of holding down shift when turning it on but I can't edit the program! Can somebody please help?

Ingo · Answer

The boot loader cannot find the root partition. There are some possibilities which will fail boot up:

The entry for root= in /boot/cmdline.txt is wrong.
The entry in /etc/fstab for the root partion is wrong.
The root partition isn't formated as ext4 filesystem
There is no root filesystem on the root partition

Sorry, been there, done that. 
I know that does not help  you , but shift to "recover" did not fix 
anything for me either.

Your SD is most likely kaput - probably powered down at wrong time. 
. 
To verify - try reformatting it OUTSIDE Pi.
