    I have a mid 2012 MacBook Pro and I think I’ve deleted hard drive and or OS

    I have entered disc utilities and tried things with no luck.

    When I go to install macOS High Sierra I get this

    What can I do. I do not need to save anything on the laptop.

    I also get these when trying other things

    If you have a backup of your data, boot into internet recovery, open disk utility, delete and recreate partitions, and reinstall the OS.

    I don’t have a backup for this machine.

    I do have a backup from a newer machine (see below) on an external hard drive.

    To make thing worse I’m not very savvy in these areas

    If you have data on the deleted drive that needs to be recovered, I recommend that you stop using the machine, remove the drive, and place it inside a usb enclosure, and use another Mac to copy the drive's content to another drive.

    I do not need anything recovered.

    I just want the hard drive/OS back/reloaded

    Boot into internet recovery (holding option+command+R immediately after startup) > disk utility > view (change to "show all devices) > select the internal HD > Erase and rename etc. Exit disk utility and reinstall macOS

    Same as ^ ^ ^ ^

    Boot to Internet Recovery.
    Erase the hard drive, using Disk Utility.
    Quit Disk Utility, then reinstall macOS.

    Did you boot to Internet Recovery?
    restart, holding Option - Command - r
    You will see a spinning globe on boot - not the normal Apple icon.
    Before trying the macOS install, run Disk Utility, and make sure that you have selected Show All Devices, under the View menu.
    (The OS X Base System is like a virtual drive, and is just used for installing the system. It is NOT a real destination for your install, and can't be used for one. That's why it is "greyed" out. It is locked, because it is just an image. You can't install to it, nor can you unlock that system.

    If NOTHING else other than that Base System shows up in Disk Utility, even with Show All Devices selected, then there's no destination (no hard drive installed, or whatever storage device is installed is dead.
    Next step is to try a different hard drive.

    The hard drive is seen according to screenshot in the first post.

    Are you able to get into disk utility from internet recovery?

    The "OS X Base System" is the name used by the installer disk image, not any proof that a working hard drive exists.

    @shakey55: boot to your recovery system, launch Disk Utility, and show us a screen image of Disk Utility with "Show All Devices" selected.

    OP:

    Look at the second image you posted in your original post above.
    It shows the Disk Utility window.

    Right now what you're seeing -- "OS X Base System" is a PARTITION on the physical drive (not the drive itself).

    Look at the "View" popup in the upper left of Disk Utility's window.
    Click on that and choose "show all devices".

    Now you will see a change in the list right below it.
    This will show you "the physical drive itself" and partitions that are on that drive.

    You need to erase the entire drive before you re-install.

    BUT -- you can't do this while booted from the recovery partition.
    You need to boot to internet recovery instead.

    So... do this:
    1. Boot to internet recovery
    2. Don't run the OS installer yet
    3. Go to Disk Utility, and again, choose to show all devices.
    4. You want to click on the TOPMOST item in the list, which represents the physical drive
    5. Erase it to Mac OS extended with journaling enabled.
    6. Now quit Disk Utility and open the OS installer
    7. See if it will let you install now.

    Glad you got it resolved. Now that it's done I've got to ask.....how in the heck did you manage to format the drive?
