Delete NO NAME EFI partition after Bootcamp failed

Bootcamp failed attempts created 2 NO NAME EFI partitions. Im on a macbook pro 2011 on high sierra (macbookpro8,1) and I was trying to dualboot windows 10 with bootcamp. I ran the "Install Windows 7 or 8"but it failed so I tried again. After I noticed 2 identical EFI partitions unmounted with diskutil list. How can I dafely get rid of these? I know my EFI isnt broken because I can restart macos normally

Earlier Mac models

First and foremost, have backups of everything across all partitions.


One of the design goals of storage partitioning is to ensure the ability to lose data across all partitions due to errant commands and random bugs in any one partition.


Seriously consider creating a bootable installer before proceeding:


Ensure you have backups of everything you value here, as partitioning may well corrupt the universe.


Did I mention backups?

diskutil eraseVolume free free disk0s4
diskutil eraseVolume free free disk0s3
diskutil apfs resizeContainer disk1 0g

If diskutil and Bootcamp assistant is still unwilling, erase and reformat, and migrate from your existing backup. The bootable installer may or will be helpful here.
