Removing windows partition

Hello,

I intended to install windows on my mac through Bootcamp but it didn't work out. So I Wanted to remove the 45GB partition that I created for Windows But disk utility won't allow me (doesn't show "-" button)

(I missed around with it and erase with several formats but it didn't work.)

Here is the terminal result of the diskunit list:

Before this, I only had my main partition on my mac, but now I feel like several partitions added to my mac (like disk0s4 and disk0s5 in the first picture I've posted).

Can you help me remove the windows partition and if there is any extra partition help me remove that as well?

Thanks!

If you have any external storage connected, the current layout is the result of such connected devices.

diskutil eraseVolume jhfs+ BC1 disk0s3

diskutil eraseVolume jhfs+ BC2 disk0s4

diskutil eraseVolume jhfs+ BC3 disk0s5

diskutil eraseVolume jhfs+ BC4 disk0s6

diskutil eraseVolume jhfs+ BC5 disk0s7

diskutil eraseVolume jhfs+ BC6 disk0s8

diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s8

diskutil list

If you only see disk0s3, then

diskutil eraseVolume fat32 BOOTCAMP disk0s3

and run BCA and click on Restore/Remove.

Run SMC/NVRAM Reset once you cleanup, before you try to install Windows again.

Thanks, Loner T.

I didn't have anything plugged into my MacBook Pro.

I did the first step and the terminal result is:

and my disk utility is like this:

What should I do after this step?

I couldn't resist not changing anything, So I noticed with the first step you mentioned, the minus button activated in disk utility so I remove partitions from there. Then I Run SMC/NVRAM Reset. And my problem solved.

Hope I didn't miss anything up!!
