I completed with no surprises the install of SP-1 from the purchased CD. Upon rebooting it 1st shows the Dell Logo Page, Then a text page with the typical F8 boot choices. Selecting any option, displays the XP Logo with moving diamonds for a few moments, then returns to the Dell Logo & the F8 boot choices.

Have others encountered this problem? Does anyone have a fix?

I have notified Microsoft and they are investigating.
