HP Compaq Pro 6300 SFF stuck in black command prompt screen after replacing hard drive

[Naroxas]

Hi, just recently I replaced my orignal HDD with another HDD that has 1TB on it, (the orignal had around 460GB on it) so after I installed it, I powered on the computer but its stuck on a black screen that looks like some sort of command prompt as there is a white line thats blinking on and off. Everytime I press a key on the keyboard, it plays a loud beep sound from the internal speakers. Can I get some help? I do not know how to resolve this issue.

You've pressed too many keys when the system is unresponsive and filled the keyboard buffer, that's why it's beeping at you.

Normally when you install a new/blank HDD, you'll be left with a message similar to 'no bootable device found, insert system disk'

Not sure why it's 'hanging' at the flashing cursor.

Make yourself up a Windows 10 installation USB from here: https://www.microsoft.com/en-gb/software-download/windows10

If you had Windows 10 on the old HDD, then it'll activate automaticlly when you install on the new hdd when you're 1st connected to the internet.

Insert the stick once you've made it (on another computer) and when you turn on the other one, keep tapping F9. When prompted for the boot device, choose the USB stick. Follow the prompts to install Windows on the new 1TB drive. Make sure you select the correct version if prompted (home / pro) as it will only activate if it matches the version on the old hdd.
