Q: 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.

MacBook Pro with Retina display, OS X Yosemite (10.10.5), MBP Retina 2015 13" 250GB

    Okay. I removed the Microsoft folder. Now if I boot with the Alt-key I have "Macintosh HD" and "EFI Boot" as an option.

    Nothing happens - the screen gets black and stays black. I need to turn off the MacBook holding the power button for 5 secs.

    Yeah... Finally "Macintosh HD" is the only boot option on bootup. Thank you so much for your patience and your support! One last question: Is there anything left I need to do? Or am I now able to clean install Windows 10 via BCA from an USB device? Thanks so much!!

    I just wanted to reply that everything is working like a charm now - thanks to you! Installed and activated Windows 10 without any problems.

    One more step, please backup OS X and Windows to separate external disks as a baseline for future recovery.
