  1. OMG. Thank You. I thought I screwed it up. Followed Apple Directions to erase my Mac and then i had no drive to select to reinstall OS. Stuff Apple. You guys nailed it. Awesome.

  2. Catalina Vergara

    Thank you so much for the help, I was freaking out. Question, is it because my Macbook Air is from 2012 that it’s installing OSX Mountain Lion?

  3. I am stuck in the install macOS select target disk step. Not able to select. Already format extended journal, GUID. Help plz

    Urgent

  4. Mine has a place to select where I save to,size,encryption,partitions,and image format. I’m a little confused and need some help.

  5. Gave it a try for myself as I was not able to find a disk to install MacOS High Sierra
    I went to disk utility and found no drives that were named VBOX Hardware Media or something close to that, nor did I find any drives at 100gb (even though I have already have a drive with 100gb available.
    Tried adding a second 100gb drive, but that didn’t work either

    1. You can click the View drop-down list at the left top corner of the disk utility window, and select the Show All Devices, or Show Only Volumes menu item to display all the VBOX HardDisk.

  6. This step was labeled differently (I copy and pasted the step I’m referring to below). There was nothing labeled “virtual disk” or anything like “VBOX”. I also didn’t get a pop-up window, but there was a place to put in the partition name “Main Disk” kind of like the example. And it had a default partition default of “Mac OS Extended (Journaled)” and a place to click erase. Voila! The rest of the steps unfolded as presented in this AWESOME tutorial. Thanks, thanks, thanks!

    I don’t have the disk that you used only the two which is the Apple disk Image and OS X Base System, what do I do?

    1. I also have same problem, so I can’t pick a format cause the “Mac OS extended” is it it’s default state and I can’t erase. It’s not letting me it’s just grey
      Did you fix yours please let me know

    1. Thank you so much I was actually crying I had exams the next day and assignments to do I tried for 5 hours to get the Mac to work but I couldn’t thank you so much!

    Thank you so much!!! I start college next week and it’s downloading with 6 minutes remaining so glad i found this and did take it to get fixed!! Thank you so much

  9. Hi,
    When I start the VM, it gets stuck with a grey screen, with nothing there except for the mouse. Please help me fix this.
    Thanks

  10. Thank you. I can get past the no disk to select issue.
    There is a small step missing that’s tripping up some.
    You have to click VBOX HARDDISK Media on the left, then Erase.

  11. Thank you for trying to help, but this did not work for me. I have the same problem as above, but I cannot click the “Erase” button in Disk Utility. It is light grey. I am able to click the First Aid button and it says that the repair is successful. There is still no disk to install when I am asked to select the disk I want to install OS X.

      1. You can click show all devices in the apple disk utility, in the top left corner. Then all the disks will show up and you can format the one you like.

    1. Maybe you need to mount the disk by hand. You can right-click the Virtual Disk in Disk Utility window left panel and then click Mount button in right panel top area to mount it, then erase it.
