Hi. I am having trouble loading xp after an update to sp2. Several weeks ago, I did a system recovery to a pre sp2 state. My hard is partitioned with a recovery program. I had updated sucessfully before to sp2 and kept it updated for some time. Now when install sp2, it hangs at a blue xplogo screen and blinks "Please wait............" for hours. I can only get it to boot after restoring to the point before installing sp2. It will load into safe mode. What can I do?
