    First, how did you try and wipe the drive clean? If it's your internal drive, you can only do that with Disk Utility running externally (or via the hidden Recovery HD partition).

    Secondly, have you been making backups? If not, then what you are doing is extremely risky.

    Third, why do you want to erase the drive?

    Fourth, if you must erase your internal drive (even if you don't care about not having a backup), you would need to boot to the hidden Recovery HD partition. This link explains how to do that, along with which version of the Mac OS you will get depending on which key combination you used:

    https://support.apple.com/en-us/HT204904

    In your case (although I STRONGLY emphasize that without a backup, it is extremely risky), you would first select the 4th option on the screen that appears, Disk Utility. Using it, you would erase and format your internal drive. The format to use is Mac OS Extended (Journaled), and the Scheme would be GUID Partition Map.

    Once that is done, you would choose the second option, Reinstall macOS. Be aware that the download of the applicable Mac OS and the installation will take some time.

    By the way, what exact Mac model do you have?
