How to replace system files in ubuntu

[newprouser]

I was trying to boot Ubuntu 10.04 from a VHD. But it requires replacement of original initrd files in the "boot" folder with modified versions.

Now my question is how does one replace such files ? The paste option is automatically disabled. I tried with Live Ubuntu CD , but still it cannot replace files in the installed version.

You need to be "Root"

First and foremost, you have to be root. That means

sudo

has to be used. You should try

sudo nautilus

, then you can copy and paste.
