My Toshiba Laptop L505D will not boot. The hard drive died and could not recover it. Replaced it w/a larger 500 GB Toshiba drive.I have windows 7-32bit. No mater what I try all I have is a black screen. I also trued window 8.1 because of no support for 7 that is coming soon. A clean boot did not work.. I saw on a toshiba site about bootable software disc. Don't know about it.Any help would be appreciated .
