Hi, a friend asked me to wipe clean her computer and reinstall windows. How do I do this? I have tried to do it once, but it appears that the windows cd she has (a "reinstallation" cd) is not bootable (i have changed the boot sequence to the cd drive to no avail). So i followed the instructions on the screen in windows. However, windows installer asks me where i would like to put the temporary files for the installation. i have no choice except to put them somewhere on the hard drive i want to format. Later on, after the comp reboots, i try to format the hard drive but i am told this is not possible because windows has copied some files it needs onto the hard drive. is there a way around this? can someone help please?
