So I'm trying to install Windows XP from USB. I get to the point where it checks my C drive and says it can't find anything or something to that effect. I have been reading online that I need the sata drivers in the install ISL. When I attempt to put them in using nlite this is what shows. Which is not a driver for Dell Optiplex 755. My service tag is:544jyf1 Got my drivers from here http://www.dell.com/support/troubleshooting/us/en/19/servicetag/544jyf1?s=BIZ Any help would be great. Thanks.
