USB drive not showing up in BIOS

Alright, before I explain the problem, let me give you some information.

I'm running an AMD CPU with a GTX 1050 ti graphics card. I had no access to a real Mac, so these are the steps took to install MacOS.

1. I partitioned my hard drive leaving around 100 GB of storage for MacOS. I already have Windows installed for practical purposes.

2. I got the MacOS Sierra installer from AMD OSX.

3. I extracted the file and downloaded from the .torrent file using BitTorrent.

4. I downloaded TransMac and formatted my USB drive for Mac

5. I 'restored' from the disk image.

6. After waiting a while, I saw that it finished, and tried to open the drive from the Windows File Explorer. It gave me an error stating that it didn't recognize the file system and that I'd need to reformat.

7. I got back into TransMac and saw that I could view the files from there, so I didn't think that there was a problem.

8. I booted into my BIOS, and attempted to change the boot priority to the flash drive, but it didn't even show up as one of the options.

9. I've booted back into Windows, and now I don't know what to do.

I would really appreciate some help here.

Thanks,
