Can't resize Macintosh HD partition
Hello,
I've installed Windows 8.1 via the BCA on my MacBook Pro and upgraded it to Windows 10. Now I wanted to perform a clean installation of Windows 10 via the BCA afterwards to get rid of the Windows 8.1 overload.
My first problem was that BCA did not recognize my Windows installation anymore (because of the upgrade). So I started in recovery mode to delete the three partition which belongs to Boot Camp (disk0s4, BOOTCAMP and disk0s6). There are still two problems:
1. My Macintosh HD only has 169 GB but I have a total space of 250 GB. I'm not able to resize my Macintosh HD partition (even in recovery mode).
2. If I hold ALT while booting, I still see Windows as a boot option. But I don't have any Windows partitions left on the system.
What should I do now? I want to remove Windows as a boot option and get back the full 250 GB for my Macintosh HD partition.
Thanks in advance!
PS: If I type diskutil cs list in Terminal I only get one CoreStorage logical volume group named Macintosh HD.
