USB memory stick for Ubuntu install

[Bob]

I just had a memory problem on my desktop computer.  I have a DVD with the
Ubuntu install on it.  What I want to do is add the BADRAM parameter to grub, I
dont see a way to do it on a DVD.  So a USB memory stick should allow me to do
that.

My question is after I load the Ubuntu install on the USB memory stick can I
edit /etc/default/grub and then do an update-grub to replace the boot grub on
the USB stick?
