What am I doing wrong? I have a Toshiba Satellite L-505 s5993. Hard drive died. Got a replacement, a WD3200BPVT (Blue). BIOS recognizes the drive. Dos does not recognize it so it will not let me install Windows. Boot disk loads up the system recovery options. I can get to a command prompt. Will not boot from Windows7 install disk. What did I miss? Pulling my hair out over something that should be super simple! Please help!
