Unable to start Mac from a bootable USB drive.
Since you don’t have a Mac, I’m assuming it’s not an authorized copy. Is the 2008 Mac Pro compatible with El Capitan? Also, try connecting it and holding Option R to boot into recovery. If that works, it should automatically download and install the latest OSX from Apple’s site.

A specific key combination can trigger a forced reinstall if you have the folder marked with a question mark during startup, though I’m unable to locate it now but remember using it helped. Using a USB drive is a more convenient alternative compared to relying on an external device.
I attempted to use option (alt) and r together after powering up, but nothing occurred. I ended up seeing a white screen with flashing folders since I don’t have an operating system installed. I’m unsure if OS X is supported and didn’t follow the tutorial because it didn’t work for me. I also don’t know if El Capitan is available. From a website I checked, it seems to say it’s available. Could you share a link and detailed steps on how to properly download and install macOS? All the OS versions I see look like updates. Thanks!
