hi, my friend wanted to make a dual boot windows linux machine. He has two harddrives and we sucessfully made a switch to the front of his computer to switch between the hard drives. Heres the problem- I start up knoppix while the second hard drive (the blank 1) is on and in knoppix i press CTRL+ALT+F2 and then type in knoppix-installer. I follow all the steps and then it says that the drive is a read only drive and that i also don't have permission to write to the drive. What am i doing wrong? Please someone help.
