i am an amatuer at best and i have just downloaded Vista (twice). first i chose to be ignorant and i loaded it as an up-grade...mistake! well after chasing down bugs and drivers i decided to re-install using a clean install. it worked beautifly. i am really enjoying the system and so far no real problems at all (unlike before) i read the forum and pblished pare "So You Overwrote XP". so i started to investigate the damege. somehow i still have "windows.old" however i do not hve all the files. i am missing: \ntldr \netdetect.com \msdos.sys \boot.ini so... my question is; knowing what i have done would it be still possible to return to XP or should i just quit while i am ahead.
