Okay well I am trying to reinstall windows on my custom pc I have tried to go into the boot sequence by hitting F12 when the comptuer turns on but for the life of me I can't change the the sequence to CD/ROM. when i get to the boot sequence it has a little start next to HD i want to change this to CD/ROM so that I can reinstall windows from my OEM windows cd can someone help me with this. If i hit del when the computer starts i can get into the bios and change stuff in there but i can't change the boot sequence as a matter of fact the boot sequence isn't in the bios its in a separate option when the computer starts but i can't change anything in that menu i hope this makes sense. i did just try putting the windows disk in and reinstalling windows which worked but now i have no desktop icons other than the recycle bin what happened to the icons? also in my c drive i have a folder called windows.old when i reinstalled windows it actually said that there would be file created named windows.old and that is where my previous windows install would be so that is not a big deal. what is a big deal is that i can't seem to put a clean version of windows on my computer. i tried to format my hd and it won't let me do that b/c that hd is where the current windows install is. help please.
