Often times when I have Windows XP installations which will not boot one of the first things I will try is a check disk from the recovery console. This will often times fix Windows file problems which are preventing Windows from booting properly. In order to do this you will need a Windows XP installation disc.
Last week I spent a lot of time trying to upgrade the BIOS on a Dell Poweredge 650 server which ended up being a pain not only because the server is so old but because of various other issues I ran into along the way. This weekend I thought I was going to be in for the same issues when I wanted to upgrade the BIOS on a Dell Poweredge 2650 but thankfully I was incorrect. After initially attempting to upgrade using the same floppy disk method I used on the PE650 I decided to try the Redhat executable provided by Dell and ran into an error which is noted below along with what package was installed via the Yum Package Manager that resolved the error.
