GRUB error 2

Ubuntu 6.06 is installed on Dell Dimension with 2 HDs : Win XP/SP2 on primary & Ubuntu 6.06 on secondary drive. Frequently during bootup err msg "GRUB error 2, plz wait" appears. Only recovery is to re-install Ubuntu. A bug report has been filed but no action taken.

(1) how do i learn what various GRUB errs mean ?
(2) how do i uninstall 6.06 so that Win XP is only OS running ?

Thanx.

Introducing Remo - An Easy Way to Secure an Insecure Online Application with ModSecurity

Say you have a nasty application on your Apache webserver that has been installed by some people from the marketing department and you can neither remove nor patch it. Maybe it is a time problem, a lack of know-how, a lack of source-code, or possibly even political reasons. Consequently you need to protect it without touching it. There is ModSecurity, but they say this is only for experts. A straightforward alternative is Remo, a graphical rule editor for ModSecurity that comes with a whitelist approach. It has all you need to lock down the application. http://www.howtoforge.com/remo_modsecurity_apache

Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch)

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. http://www.howtoforge.com/virtual_users_and_domains_with_postfix_debian_etch

How To Block Spam Before It Enters The Server (Postfix)

The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails. http://www.howtoforge.com/block_spam_at_mta_level_postfix

The Perfect Xen 3.1.0 Setup For Debian Etch (i386)

This tutorial describes how to install Xen 3.1.0 on a Debian Etch system (i386). Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called virtual machines or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. http://www.howtoforge.com/debian_etch_xen_3.1

Login loses first character

I have a new install of Kubuntu and a minor problem with the login screen. My user name is displayed by default when the screen appears. The cursor is blinking in the password field. When I begin to type the first character is not recorded. In order for the login to work I have to first type a space or type the first character twice. Is this unusual? I have been using various Linux distros since Red Hat 8 and this is the first time I have encountered this sort of problem. I hope this is not a "feature" because it is annoying.
