I went through a nightmare installing Windows and formatting again... i downloaded 2 different ISO's off the net and NEITHER would work, one kept crashing and the other gave me an error about digital signing during install... so i used BOTH.. it worked but the by product is that my pc now sees TWO winXP installs on bootup..
I deleted the windows folder i didn't want but it still sees it , is there some other file hidden i should know of ?
