Yesterday I tried to install Win10 through bootcamp, but it couldn't install it on the premade partition. Eager as I was i meddled with the partition scheme during the installer but with no result.
While in pain that I couldn't get my dual boot right, I wanted to reset the partition-table by using bootcamp, only it gave me this error:
The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.
I'm currently stuck using DiskUtils to delete the partitions and make my HDD whole again. But it won't work.
This is the output from diskutil list
/dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.3 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage Macintosh HD 401.4 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: EFI NO NAME 104.9 MB disk0s4 5: Microsoft Reserved 16.8 MB disk0s5 6: EFI NO NAME 104.9 MB disk0s6 7: Apple_HFS Backup 96.7 GB disk0s7 /dev/disk1 (internal, virtual): #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Macintosh HD +401.0 GB disk1 Logical Volume on disk0s2 F6E64063-7D4B-4D75-AAC5-C4D128919CD3 Unencrypted
My Mac model is MacBook Pro mid 2015.
The desired goal is to lose all partitions, including the "Backup" partition, which I can not seem to delete using the Disk Utility application. Eventually, I want to have a single Mac partition, which is required by the Boot Camp Assistant application to install a Windows 10.
