macOS Sierra cannot be installed. Unable to Unmount Volume for repair

[oljik]

No matter what I am having this error after reboot, on second stage of installation

 

macOS Sierra cannot be installed on this computer

 Unable to Unmount Volume for repair

 

I have tried booting macOS install from Clover in USB and in internal HDD.  I have tried to Use Chameleon bootloader to install Sierra, but it is only booting into Recovery Mode. I have also tried to Update from older macOS, but again that Error after reboot.

 

HP Pavilion DV6-6180us

Intel i7-2670QM

Intel HD3000+AMD Radeon 6770M

Renesas USB 3.0

 

There is also issue with USB

USB3.0 is not Booting Clover From USB and Clover is not booting from USB3.0

But MacOS is not recognising USB2.0 when installing and throwing SATA WARNING: enable auto-activate failed

I have past this error by changing USB installer to 3.0 after the kernel being loaded

USB 2.0 is also not recognised in my older Yosemite installation using GenericUSBXHCI.kext

Hi! Sierra uses different approach to USB! 

You have to use ports injector or another approach. It's seems to be common issue with Sierra now.

I have resolved that issue by connecting HDD externally by USB on another Laptop and installing Sierra there.

 

Or maybe I had Port Injector in my Clover kexts folder, don't remember.

 

Thank you

I have solved this problem by erasing and repartitioning SSD from installation DiskUtility.
