    Hello,



    While rebooting, I pressed command and R and went to Disk utility, then i went to Machintosh HD and i erased it because i wanted to erase everything on my imac to start fresh, i also clicked ''restore'' and then Machintosh HD disappeared instead i have now ''OS X base system'', Then i exited and restarted my computer to log back in and now i cant.. Apple logo and the bar gets filled up but it gets stuck and restarts again. I did not back up anything because i don't have anything important in my computer and as i said i wanted everything gone so i did this and now i cant get pass the apple logo. I cant reinstall Mac OS Sierra because it says '' this disk is not formatted as MAC OS extended (journaled)'' I really don't know what i did wrong and i suck at fixing problems like this. Anyone know what i can do?

    Hold CMD + R again on startup. Open Disk Utility again.

    In there you should see your actual hard-drive without a Macintosh HD partition. It might be the name of the hard-drive (some generic stuff like ST500-BLAH). Then click that and Erase or create a new partition. From there you can select it to be formatted as Mac OS Extended (Journaled).

    I appreciate my comments are a little ambiguous, so feel free to quote/reply to this with photographs attached of what you see, and we'll run through step-by-step if necessary to get it back up and running!

    Not to worry! Select the very top hard drive listed as you did in photograph #2 (Apple HDD ST1000). Then select Erase near the top. You should have an option for erasing as Mac OS X Extended (Journaled). Then once formatted, reinstall.

    It looks like you may have previously restored the Recovery partition to your HDD through Disk Utility, which is causing the issues you're having. Reformatting with the above steps should hopefully resolve the problem!

    EDIT: As @Weaselboy just pointed out to me, the above steps will only work in the Internet Recovery (by holding CMD + ALT/Option + R on startup), as holding CMD + R boots into the Recovery partition on the drive itself and you won't be able to reformat that way.

    So if you haven't already, run through the same steps by holding CMD + ALT + R & it should work. Apologies for the misinformation. :)

    What do you get when you boot holding Option(alt)-Command-R?
    You SHOULD see a spinning globe (not the Apple icon), then a relatively long boot which may take a couple of minutes to boot to a very similar menu screen that you get with Command-R. Erase the hard drive using the Disk Utility, then reinstall OS X. It will offer you the original system that shipped with your iMac (probably 10.8 Mountain Lion on your iMac13,1.
    Once Mountain Lion is installed, you can upgrade to a later version of macOS, if you want.

    Two questions.

    On what iMac are you doing this, where did you download OS X.12 Sierra from?

    OP has an iMac13,1 - either Late 2012, or Early 2013, 21.5-inch iMac. I got that from the boot error screen in post #3.
    (And, OP appears to NOT have Sierra (or any local system) installed now :D )

    You get the flashing folder/? when there is no system to boot to.
    In this case, it's because you erased your hard drive.
    Usually, erasing the drive from the recovery system does not affect the recovery system itself, so you can still boot (command-R). But, now it appears that you have succeeded in removing the recovery system, too.
    So, what's your choices now?
    Boot to internet recovery, and install what is offered by Apple's servers. Internet Recovery boots to Apple's servers, so you need a working internet connection just to boot to that.
    And, you need to try a different internet connection.

    The internet recovery error that you get (Apple.com/support -2002F) is usually a network problem.
    Try connecting using a different internet connection, particularly wired ethernet is a good choice, rather than wireless.

    Erasing the drive from the recovery system certainly does affect the Recovery system - Erasing the physical HDD (Apple HDD HD10... in the above photos) erases all partitions, including the Recovery partition.

    As long as the recovery OS is loaded into RAM, not a big problem - after erasing the physical HDD (which will also create a new Macintosh HD partition), go back to OS X Utilities to Reinstall OS X. Under these circumstances, the same version of OS X that was present on the machine previously will be reinstalled.

    However, rebooting the system right after erasing the physical HDD is going to leave you with a folder with question-mark. There's no Recovery partition to boot from. At that point, Internet Recovery to the rescue.

    Based on the illustrations, back in the beginning the OP probably Deleted the Macintosh HD partition, rather than Erased it. The Recovery partition was still intact, as shown in the photos. At that point, the OP might have been able to create a new Macintosh HD partition, without further erasures, though an erase of the physical HD may still have been the better route.

    Now, however...

    he OP has to get into Internet Recovery... the most recent screen shots suggest a problem with connecting to the Internet. It may take a reboot of the router, or connecting to the router with an ethernet cable to get Internet Recovery working as it should.
