If your Mac is 2012-2014, BC Assistant will let you create a USB Installer, which can be used to boot from and then repair the internal disk installation. This is useful if there is corruption of NTFS where utilities may not start properly or chkdsk reports issues or diskpart is needed to activate volume or clear the read-only attribute.

Hi Loner T, I'm on the same problem, I can not start Windows 10 on my MacBook Air.

In short, reduced the Macintosh partition 90GB to 80GB HD and unable to allocate space 10GB free at (BootCamp) Windows, I returned to assign the Macintosh HD 90GB running again

I try to follow your footsteps, but no where to create the MBR and partition to assign

I'm too worried because I have some software licenses on the Windows partition and do not want to lose.

I'll thank me much help.
