Can't Delete Boot Camp Partition

Can't Delete Boot Camp Partition

Hi all,

First off apologies for ANOTHER boot camp post, but I've noticed they seem to be specific to each user and I just wanted to make sure I'm doing the right thing.

Anyway, My Windows 10 upgrade to bootcamp wouldn't install due to lack of space, so I formatted the disk via the installer. This said it failed but erased the disk as expected and Win10 still wouldn't install.

Went back to MacOS and tried to delete the partition from Disk Utility (before I knew that you shouldn't!) which failed.

Long story short: I just want to add this 126GB partition back to the main partition without affecting my data and start my boot camp install from scratch. Can somebody help?

In other threads I've noticed Loner T asks for the result of the diskutil list command in terminal:

Thanks in advance!

Can you erase your full internal disk and restore your TM backup and retry?

See Restore both macOS and your files in Restore your Mac from a backup - Apple Support for reference.

Backup your disk on a Time Machine harddrive, download "Install Disk Creator", download a valid copy of your Mac OS X version installer, create a bootable Mac OS X USB with "Install Disk Creator" and the Mac OS X installer, turn off your mac, start your Mac while pressing the Option key, plug the USB in and select the new startup disk you see in the menu(Should be called Install Mac OS or something, I don't remember).

Hi LT,

Great, that seemed to work successfully – albeit with a few warnings?:

Although the main disk is now a single partition, there's a 9.6GB area called 2 not mounted and a section called Other Volumes weighing in at 11.51GB. Not sure if they're connected to the old Windows partition or if I can reclaim them somehow?
