I understand this is because I am not the same person who installed that OS? It's now asking for my Apple ID and then says the item is not available. Naively, I ran the recovery, erased the drive and started the OS installation - it says it's Mavericks, I thought it could be a good starting point. I understand this laptop can install El Capitan, 10.11. I fixed it and now I'd like to do a fresh install of the OS.

I've rescued an old MacBookPro from the bin - Core 2 Duo, 2.4Ghz.
