My desktop has windows xp media center edition with Sp3 and for years it has run well, and maybe it's time to junk it, however my laptop has windows vista, which I dont like, I have seen windows 7 and am not fond of it either, so what can I do? when I load up the system restore disks it only loads up to a point where it says it is copying files, then tells me the restore is completed. When booting up again I am told the file "<windows root>\system32\hal.dll" is corrupt or missing, and to reinstall. it,. How do I do that? Thanks for any help.
