I've got an original unibody Macbook Pro (late 2008 variant), and the hard drive has started to fail. I've taken this opportunity to upgrade it to an SSD. However I'm unsure as to the best way of installing OSX onto this new drive. The laptop was running 10.10 (I also have an iMac running 10.11). I have a time machine backup to a NAS of the original hard drive, and a USB caddy that I can use to boot from the failing hard drive (it still works, but has quite a few bad sectors on it). Additionally, I also have a bootable version of 10.5.8 on an old firewire hard drive. What is the best way to get OSX onto the new hard drive? I could clone the original but am worried that'll also copy any potential corruptions over. The laptop does also support 10.11, although I never got round to upgrading. Given the age of my computer it doesn't support internet recovery. Thanks for your help!
