i wiped my computer because of a continued slow problem, it would go in and out of service like i had a bad internet connection every 30 seconds to two minutes, for 20 to 40 seconds, sometimes the screen would fade and say not respoinding. my connection was fine, after microsoft taking it over and reinstalling windows 10 the problem was still there. so i wiped everything with deriks wipe out i bought off ebay. now i cannot get anything to reinstall, id like to go back to windows 7, which my 2010 HEWLETT PACKARD touch smart 300 {1223}CAME WITH. IF thats not possible i have windows 10 on usb,if i dont have any disk in the computer it boots to the realtek screen and stays .it wont accept any commands at all f10. f11, f12. esc nothing, it says reboot and put disk in. if i put hp repair disk in i get the microsoft logo abd after a lkong time i get the language option if i repeatedly push f12 power up. then it gives me the option to fix computer or advanced troubhleshooting, if i pick fix, it says cannot fix hard drive c is locked. if i go to command prompt and follow unlock instructions it says c drive is raw. cannot fix, i have no operating system, and cannot hook up to internet, so i cant get bitlocker to unlock it. does anybody have any ideas. thankyou
