Trying to factory reset my macOS high sierra 10.3.6

I have been trying to update my macOS high sierra 10.3.6.But, when I tried download the update, I made the mistake by erasing a disk. I tried searching to see if my problem would solved, but nothing helped. I also don’t have Macintosh Hd on my computer . This is my last hope. :)

Without any basics such as the model year of the iMac and what you were attempting to do it's very difficult to assist you. When you don't really know what you are doing then these forums are a good place to start, not a "last hope."


Follow the steps in What to do before you sell, give away, or trade in your Mac. However, if you intend to keep the Mac then restart in the Recovery Partition and restore from your Time Machine backup. Restore your Mac from a backup. If you were operating the computer without a backup and you successfully erased your HD then you are about to learn a VERY painful lesson on why backing up is absolutely critical!
