I got a Macbook pro from someone but the hard Drive was gone so i installed a new hard drive with macos on it but it keeps giving me the prohibit sign even after doing mac recovery from online. it won't let me get to disk utility to try and repair the disk.
MacBook Pro
Maybe the version of macOS on the new drive cannot boot that Mac.
The prohibitory symbol means the system cannot boot from that startup disk.
If your Mac starts up to a circle with a line through it - Apple Support
