2012 MacBook Pro with error -37

Not sure Catalina will install on a HFS formatted hard drive, I believe it will want APFS format.
But do yourself a favor though, get yourself a 500gb Crucial SSD for $55 (or some other name brand 2.5 inch SSD) and install your system on that. You will love the difference in speed and usefulness of that 2012 machine. Changing the drive is I have a 2012 MBP 13 inch and when I put an SSD in it, it was like a new machine. So much faster and responsive. Also be aware that the SATA cable is known to go bad in those machines. If your machine was running unusually slow with the previous operating system, you may need a new cable. They are also easy to replace and cost about $14.
