Made a mess editing boot.ini of my dual-boot Acer Aspire One netbook so that XP boots first & now will not boot in XP, giving error:-
"Windows root>\system32\hal.dll is missing please re-install a copy".
I cannot install "hall.dll" but, I have XP home on a stick.
1. Can I reinstate the ACER now to manufacturer's condition? or
2. How do I go about reinstalling XP? Note that it boots in Ubuntu 11.04 OK, but not in XP.
