(2nd try/lost post over login issue)
I gather that I need root privs to upgrade Fedora linux kernel.
I gather that this the necessary changes could possibly be performed in the grub configuration file.
The problem is that all of my linux kernel upgrades render a message claiming trouble accessing hd0 (sole Fedora hard drive).
I read a lot of posts today and it's my opinion that the new Add/Remove programs has no way to implement root privileges for Fedora to boot the upgrade.
