boot camp install win10 failed

I upgraded MacOS to 10.13.2 just now, and do BCA again, got a new error. "Your disk could not be partitioned".

Checked with Disk Utility, there are additional disk image made by BCA like the third one in blow image. The second one, disk3s1 is my U-disk, my external disk(NTFS) is also plugged in, but now show in Disk Utility.

Now, how to fix the "could not partition" issue?

Thanks for reply. I have tried this following your steps, still not working. 😟

Actually, my external disk(NTFS) cannot be recognized by Mac OS now but my U-disk(exFax) can be.

This external disk works well in my another PC. And it also works well before in my MacBook until I installed Paragon Ntfs for Mac and uninstalled it. For now, I reinstalled Paragon, still cannot let my external disk(USB3.0 NTFS) recognized.

Could this be the reason that Win10 cannot booting?

Finally, my issue was fixed.

The first issue, could not be partitioned, fixed by following blow steps:

There is an easy and simple-to-perform process for overcoming such an error. Whenever you get this type of an error message, you can follow the steps given below:

1 Firstly, shut down Mac

2 Then, turn it on

3 And after that, hold keys Command + S

4 This would land you to Single User Mode

5 Here, type the code (/sbin/fsck –fy) in the command prompt interface

6 And then, press Enter from your keyboard

7 Now, the command that you had entered would automatically scan & repairs any of the inconsistencies in your file system that might be holding your hard drive from partitioning

8 Once done with these steps mentioned above, you now have to type ‘reboot’ in this code

9 Then click Enter

10 Now, your Mac restarts as usual

11 Then again, try and run the Boot Camp Assistant for installing MS Windows

12 Now, you might not get this error message and also MS Windows installation would run smoothly too without any such interruption

The second issue. blue screen with stop code: ACPI_BIOS_ERROR, fixed by holding power button for 4 seconds and let the laptop power off, then power it again. It will be booting with Win10. Couldn't know why this is working, maybe this is just available for my case.

Finally I get the win10 installed and can switch MacOS and Win10 pretty well.

Thanks Loner T for help.

No. I only connected external storage to show you the Disk Utility list.

When I ran BCA to install win10, no external storage were plugged. And Paragon NTFS was uninstalled before this action.
