macOS 10.13: Windows 10 installation with Boot Camp
I tried to install Windows 10 via Boot Camp, but got stuck at the creating a new partition part. The error states:
An error occurred while partitioning the disk. Please run disk utility to check and fix the error.
Here's what I did:
- Run first aid on my internal drive
- Decrypted the internal drive
- Start in Cmd + S mode and run the /sbin/fsck -fy command
- Reinstall Mac OS High Sierra
After all this, I still get the same partitioning error as before.
How can I install Windows 10 properly with Boot Camp?
Solution 1:
This question is possibly related to Disk Could Not Be Partitioned - First Aid not helping — I'm duplicating my answer here.
I had very similar problem. After contacting Apple Support and following their instructions, I've reinstalled macos (instructions here). This is not a wipeout reinstall, but do make a backup.
After the reinstall partitioning worked like a charm.
And so do Bootcamp installation.
Solution 2:
There is likely an error that Apple's disk utility can't cope with. There are few options.
- Third party disk repair utility, but are there any that are compatible with High Sierra and APFS. Not sure/don't think so.
- Verify you have a good backup, boot into recovery mode and repartition the drive, which should fix the errors assuming they are soft errors and not hardware errors.
Number 2 has the benefit (?!) of allowing you to set a partition size for your Mac volume and leaving the rest unformatted and ready for Win 10.
