Disk partition error

I'm using a 2011 late 2011 mac book pro, 2.2 ghz i7 processor. when i try to install windows via bootcamp it says disk cannot be partitioned. I tried all the solutions online and none of them worked.

If anyone can come up with a solution it would be much appreciated.

MacBook Pro, macOS High Sierra (10.13), late 2011 mac book pro

Lauch Disk Utility.

On the little menu Icon menu at the left end of its Task bar, choose View > Device view

Select your disk by Hardware-name

Click Repair Disk/ First Aid (whichever it shows).

Wait a few minutes for it to complete. If any errors, look at the detailed description.

There are two methods of getting the 'stuck' 70GB disk space back into your main macOS partition. A Time Machine backup is highly recommended, before either of these methods.


  • Erase the Recovery HD, merge it into macOS, and re-install the same version of macOS back on your internal disk, which will rebuild Recovery HD with the correct size. You may need to temporarily re-install macOS on an external disk matching the internal disk version for safety.
  • Backup via Time Machine, boot into Internet Recovery, erase your whole internal disk (not just the macOS partition), restore from TM backup, which will also correct your Recovery HD partition.

If SSD, do you have TRIM enabled?

Yes bennet I Followed all the steps recommended by the Apple team in the above article. I even created a bootable usb drive, launched boot camp , downloaded the support software at the time of installation I get the message your disk cannot be partitioned....this is where I am stuck. I searched all the forums regarding this nothing worked. Typed the command /fsck....by pressing command+s , tried disk utility first aid by pressing cmd+ r mode... still nothing. I don’t even have a time machine backup and that terminal thing to delete copies , I tried that too.. no use
