I accidentally deleted the live kernel headers with pae while cleaning my old kernel headers. I am using Ubuntu 10.04 Netbook Remix. How can I recover. I booted with my USB loaded with Ubuntu and all data is intact. Urgent help is required...

Boot with your live USB, open a terminal and type:

sudo chroot <the_path_where_your_filesystem_is>
sudo apt-get update
sudo apt-get check

If no errors are provided, try:

sudo apt-get install linux-generic

Then restart your system without the live USB.
