Recently I have been having problems with a dell inspiron 6000 laptop booting past the welcome screen. It won't. I have performed a fixboot and chkdsk through the recovery console of the xp disk. It has service pack 2 installed. It also will not continue into safe mode because it lags on mup.sys, but then continues to the welcome screen at which it freezes. Any help would be much appreciated. I am trying to avoid reformatting. Thanks.
