Do you know if your iMac has a Fusion drive?Imac mid 2011 high sierra
Okay... you should be able to just follow the steps in my earlier post here to erase the drive. You can skip the part about (diskutil cs delete "Macintosh HD") and just do the rest.how do i find out? i dont think so.
later edit: no fusion drive. only one HDD 500gb sata

That will format the drive back to one volume. Then attach the Time Machine drive and restore.
As long as you completed a Time Machine backup to an external drive, the OS and all your data will be on there.i am not very certain how this time machine works. i bought an external HDD yesterday( some Maxtor 500gb) with the Paragon NFTS program for mac.clicked time machine..it was copying around 3 hours.is that enough? how do i restore? i never done this time machine thing.just plug/play and follow steps? even if there is no OSX?
You can skip that part and just follow the rest of my instructions in that post.diskutil cs delete "Macintosh HD"
cool.. done reformating.now you said " Then quit Disk Utility and click reinstall OS X at the top and what for the ~6GB OS to download and install. That should get you back in bussiness" so i do this and then restore from time machine OR directly restore from time machine which i have ?You can skip that part and just follow the rest of my instructions in that post.
Don't panic. I've had something like this happen before, and Apple Support had me boot from the web and reinstall MacOS. Hold down Command+R, give it your wifi password, wait a while for it to download what it needs to boot, and then you can reinstall. You'll lose whatever is on the disk, but you can re-format it and do a fresh install.So, I just purchased a 5K iMac and I went to reset it this week because I wanted to do a fresh install after transferring over files and seeing some junk that I couldn't remove.
I encrypted the HD in FileVault when I first bought it and went to restart it in disk utility and delete everything. (I forgot to undo this before deleting the HD).
It won't let me erase my HD and when I go to login regularly this black screen appears. How do I get this thing to work again?
now that i finished all this lore with time machine and everything...Its all cool...i was searching again to make a bootable USB for certain to install that windows 7.found a video -->makes sense ..was reading the comments and luckily i found a guy with the exact same problem i had/have
posting a SC of the comments...now after all this im not sure if i wanna try again to faaail again to go do this all over.
that guy still didnt figured it out.
any help?
