I have this problem since I installed the SP3 PACK OF WINDOWS XP HOME EDITION but i did not continue when it says that DVD Ram will be removed if I continue installing SP3 what I did is cancel installation... Then the problem started i cannot open now the device manager and it says "class not registered"... I'm usually using SP2.

2nd option is to do product recovery but I cannot boot from cd/dvd and is not reading though it seems its okay but nothing comes out after the reading.

3rd option for me is to reformat and install the new windows but the thing is I cannot boot from my cd/dvd even if I choose it from bios in F12... it's only restarted to windows and directly open it, if I choose safe mode it happen the same thing.

Please help i'm desperate.

Thank you so much. GOD BLESS.
