HI,
I need help as I am a new Mac user and trying to install Windows using Boot Camp Assistant. However I am not able to success since it gives me the error : disk could not be partitioned.
I ran the first aid in disk utility with no luck.
Any help will be very much appreciated!
MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.5), The PC is brand new
Can you reboot and post the output of
diskutil list
Your disk slices are out of order, which a reboot should correct.
Can you confirm the year/model of your Mac (do not post the serial number) and the macOS version?
Post the output of
diskutil list
Can you boot into Internet Recovery and run the erase on disk0s5, and then run mergePartitions .
Much better.
Run
diskutil eraseVolume jhfs+ BC1 disk0s3
diskutil eraseVolume jhfs+ BC2 disk0s4
diskutil eraseVolume jhfs+ BC3 disk0s5
diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s5
diskutil list
If you only see disk0s3, then
diskutil eraseVolume fat32 BOOTCAMP disk0s3
and now run BC Assistant and try to Remove/Restore.
From Applications -> Utilities -> Terminal, run
diskutil list
and post the output.
In the 'before' diskutil list output, disk0s3 is invalid, and should not exist.
Hi Loner,
Thank you for your help, I confirm my Mac is a new MacBook Pro with High Sierra 10.13.5.
I bought it last week online on the apple store, so it is new, but I don't know its real date of manufacture.
Many thanks in advance to help me further.
Hi Loner,
The disk0s3 must have come with the computer since I haven't installed anything yet. However I am willing to remove it if it causes the problem.
My only trouble is that this disk doesn't show up in disk utility, so I have no idea of how to remove it. Is it possible?
Thank you
Hi Loner,
I do apologize for my late reply.
I was lost with the time machine procedure. I called the Apple support and they guided me through reinstalling mac os.
That disk0s5 went away so I could successfully run Boot camp.
Unfortunately, the WiFi, backlight and function keys were not working on Windows. I tried to updated with the Windows Update Support of Boot camp, but after running it on Windows, I had a blue screen telling to press F1 to enter environment recovery. But the function keys were not working! I returned to mac and restored again.
I will try it again when I will have some time.
Thank you for your help, I really appreciated it.
Hi Loner,
Here is the output I get before installing:

Hi Loner,

What should I do please?
Hi Loner,

Thank you for your help
Hi Loner,
I did it but unfortunately the same error has been thrown.
Is there another way to achieve the disk erase?
Many thanks for your time for helping me.
