Get back into Internet recovery then in Disk Utility select at the very top where it says Samsung SSD... then erase to the correct format. That will format the whole drive to one partition. Then go ahead and reinstall.
Got a tip for us?

HELP! HD locked on reinstall!

I don't want to have to re-install high sierra again. It shouldn't be that hard to wipe a disk in recovery mode when booted to an install usb.
Weaselboy is awesome with his solutions. However, there is one more solution to this - all u need is a booted usb with any windows. Restart your mac with holding alt. Then go to UEFI, click install, select the language, then next select costom way. You are on your hard disk partion now, all you have to do is delete all the partitions until you have all the storage as unalocated. Now select the unalocated partition and just click on new below ,it will make 4 extra partitions, format all of them and then cancel installation. Unplug the usb and restart you machine and hold command +alt + R. Release the buttons when You will see a globe . Wait a while, then connect ur wifi as it asks. Wait a bit for loading. You will finally be on disk utilities. Erase your disk again for mac os. Its almost done, now go back select install mac os, select the drive and you are done. Peace out.
Run each of these commands and tell us the output.

diskutil list
diskutil cs listHi,
Sorry to bump another’s thread but I suddenly am having a very similar issue that many in here have had but wanted to seek some advice before doing anything.
I was using my computer normally a few days back when suddenly it froze and wouldn’t let me move the mouse, type, etc. so I manually shut it down thinking I could restart. Once I did, I got the continual spinning circle until the Apple logo changes to a circle with a line thru it.
I’ve tried going thru all the pages here to see any already-answered questions about this, so I did what’s been suggested ... running disk utility (no problems come up) and then when I try to reinstall OS X (Mid-2010 MBP), it only gives me Recovery HD as my option to install OS X (no Mac HD option) and the Recovery HD is locked.
I mainly care about getting several files off my computer, and after that have no problem wiping it and starting it like factory settings .. from what little I understand, it seemed like most solutions people found in this thread required wiping all data beforehand and so was wondering if there’s a solution where that isn’t necessary (or at least let’s you into the computer long enough to pull files off it? Before having to wipe it clean)
Any help would be so greatly appreciated!
Thank you !!

What you are describing there sounds like a drive or drive cable failure.
Is you MBP on this list with Internet recovery?

Yes, I believe it’s a mid-2010 one.
(Or early 2011, I’m not positive)

This is probably a dumb question ...But how would you get that update to run? If stuck in this perpetual state where nothing can be done/accessed on the computer?

At this point I would go out and buy a cheap USB3 enclosure and put the drive in that, then try to option key boot to the drive. If that works, it tells you the issue is the internal drive cable. If that does not work, you need a new drive.
If you Mac is on that list, you can do a command-option-r boot to Internet recovery to format the new drive and install the OS. Then try and recover any data from the old drive in the enclosure.
Do not try reinstalling anything on the old drive. That will just make recovering data more difficult.
Okay I’ll purchase a USB3 and report back.
What exactly does “option key boot” mean/entail doing?
I did try the command-option-r method from earlier in the thread, but would never get a globe image like others did earlier to appear when doing that .. it would just open the normal menu of disk utility/reinstall OS X

It will bring up the startup manager so you can boot to the external drive.
That makes me think you do not have a model in that list and do not have Internet recovery. Do you have a backup of some sort you can boot from?
Hello,
I have installed window and now i want to reinstall mac OS. when i trying to install mac OS it says the disk is locked.

It has to be either a 2010 or 2011 MBP 13” so both are in that list .. but anytime I try to do that combo of keys, it doesn’t bring up the spinning globe like mentioned earlier in the thread so I’m not sure why that’d be.
While I wait for my USB3 enclosure to arrive, I connected an external drive to the computer yesterday and ran the disk utility, it allowed me to install OS X on it so I did and went through the setup .. once I did, it booted up the computer as basically brand new with that external drive connected.
...if that makes a difference in diagnosing what’s wrong with it??
I do not have a backup to boot up from, to answer your question.
If it works fine from an external drive, and not the internal, it does sound like you have either a failed drive or drive cable. Can you now swap in the external you are booted from to internal and see if that works. If that does not work, then you have a bard internal cable.
Also pop the internal in the external enclosure to see if that works.
If I understand what you said, you now have a drive in the external USB enclosure that is working? Take that drive and mount it inside the MacBook and see if that also works.Sorry, what does that mean exactly?
Oh, I see. No my bad on not clarifying.
I’ve ordered the enclosure but haven’t got it yet.
I just took an extra external drive I had, and had it connected to the MBP while disk utility ran. When I went to choose reinstall OSX on it, it allowed me to choose the external drive as a destination to do so (up until then, I’ve only had “recovery hd” as an option and it is locked). So I ran the install of OS X on this external drive, and it did so and worked like a brand new comp after it was done (loaded up, started everything as normal ... all files and everything that should have been there were not though obviously)
It could be either the drive or a bad internal cable. Odds are it is the drive. The only real way to find out unfortunately is to swap in another drive and see if that fixes it.
If it were me, and you have the money, I would buy a new drive and also replace the cable since you have it taken apart already. It is fairly common for the internal cables to get flaky on those older MacBooks. iFixit has the cable for around $30.
Also, if you can afford the upcharge, a new SSD in there instead of a hard drive would really speed things up.
Thank you for all your help, I appreciate it!!
I think that is what I’ll probably end up doing.
My main concern is to be able to access/retrieve the files and things off this drive in there already.
If I swap in a new drive and assuming get the computer up and working again, there’ll be a way to still access everything off the original drive? And transfer onto the new one or something? ((Is that what the enclosure is for?))
Since Internet recovery is not working for you.... install the new drive and cable then boot to that external drive you now have working and clone that drive to the internal. Then to the new internal and try and access the old internal in the new enclosure. No guarantee it will work since it looks like that drive died, but it is worth a try.
Thanks. Will try and figure it all out once I get the enclosure.
Can I just go ahead and upgrade to a 500gb drive instead of the 250 I had originally bought the MBP with ?
