[oddjobbers000]

I have an Hp Pavilion G4-2304tx laptop win8-64bit, my hdd start having problems so I bought a new one and tried installing win10 using a cd but it doesn't show up in the boot manager, when I tried disabling secure boot and enabling legacy boot,after restarting my laptop there is no display only blinking caps key. i tried troubleshooting methods from hp and none of it works.

Any solution for this?

tl;dr: can't install win10 on new hdd using cd, disabled Secure boot and enabled Legacy after that I only got black screen. cant do anythig on it now
