I removed my login password for my user admin account, but now I cannot figure out what the authenticate password is to download/uninstall applications and updates.  I tried finding the grub menu by holding down shift button after turning on the netbook, but it won't work.  This netbook originally came with Windows 7 Starter, now it is running on Ubuntu 12.04 (just updated).  I'm trying to update and uninstall all programs I used to give it to someone, and I want to remove the authenticate password, but I don't know how to.

FYI, this is exactly what I bought: http://www.amazon.com/gp/product/B002P3KMXA/ref=oh_details_o09_s00_i00?ie=UTF8&psc=1
