I got It fixed through Apple support. Some reason when he told me to turn on my MacBook and press CMD+R my internal drive changed again with preboot, recovery, etc. I guess I just Needed to Give my MacBook some time to read the internal I guess? Then I had To partition it and install Mac OS. But yeah thanks everyone for trying to help. Appreciated it!
If your mac came with Sierra, start up while holding the CMD+R+Alt/option key, this will start recovery from internet. Choose install OS it will install the OS (Sierra) that the mac came with when sold.
You should / may be under apple care. Give apple a call.
There two recovery commands
command + r
command + option + r
command + option + r is for those in a worse situation than command + r. command + option+ r is for when you have a trashed startup drive.
command + r boots up the recovery partition.
Could you also help me keep it at MacOS Seirra.
How did you get to this point. You may have employed windows thinking.

What version of macos did you mac come with? You cannot downgrade lower than the macos that was shipped with your mac.
I have not played around with recovery... for the obvious reasons.
in command + r I'd think you could split a disk. You format partitions not a disk.
I recommend either calling apple or take it to an apple store.
for option + command + r
did you look in disk utility for the disk? only mounted disk will normally show. disk utility should show all disks. unmounted will be greyed out.

I’ll do that, but for now I want to try to solve it. So far it says I have an Internal disk and I tried To partition it into Mac OS Extended but it says the volume “recovery” on disk1s3 couldn’t be unmounted because it is in use by process 0(kernel). This is in CMD + R but as for CMD + OPTION+ R, the internal disk is not there.
I got in this situation since I was trying to downgrade high seirra to seirra.
My MacBook came with Mac OS Seirra but I had the opportunity to update to high seirra and regretted it. I’ll try to talk to the IT departmenet in college before I bother to spend any money to fix this.
Are you doing this via the Recovery Disk?
If that is option+cmd+R? Sorry I am new to macbook.
My MacBook is the retina 12 inch 2017.
Thanks for the report.

our pleasure. happy computing. 🙂
You can check your repair converge here:

You should be able to reload the system. You should be able to reformat a partition. I'll see if I can find someone with more knowledge of your system. I have a 2014 mac mini running 10.10.5. I'm in no rush to upgrade.
I have a second harddrive for backup and testing. I've install High Sierra on a separate partition.

You could try to get an external hd or flash drive [ maybe 32gig possibly even 16gig ] and install to that device. You should then be able to fix up main drive.

I accidentally deleted my startup disk and now I’m left with an internal Macintosh HD APFS Volume.
