|wait, take it slow. |
When it boots...if you tap F8 repeatedly before the windows xp screen appears, you should be able to get to boot options.
Last known good configuration, safe mode, normal stop, boot mode w/ logging..things like that.
Try to hit f8 at bootup, after the POST, and see if it loops or if it takes you to boot options...
what have you done recently? have you installed anything? hardware/software? had to be something..
let us know.
