i had this old 2007 dell laptop that was absolute CRAP.so i took it together,and i kept the hard drive just in case i might need it.well about a year has passed,and i am building a gaming desktop.on budget.so of course i don't want windows 8,i would love windows 7 but i just cant afford it,so what i did,is i'm going to use a 1Tb hdd i found in my closet,and boot from the old laptop hard drive,but there's a bunch of random old crap on my old laptop's hard drive (the one i'm booting from) and i want it gone.since i don't have ANY of the other parts,i cant just use the os recovery disk,but i have an adapter so i can plug it in to the laptop i'm using right now,but i dont know what all files i need to keep in order to still be able to boot from it.i need to know what files to keep,or software that wipes all but that.thanks
