I have tried both wired and wireless peripherals but none are working on the recovery screen or during startup. However, when I try pressing F8, F9, or Enter, no keystroke is being registered nor is the mouse working. Along were the options: Press Enter to try again Press F8 for Startup Settings Press F9 to use a different operating system. On one occasion it showed the windows recovery screen. I have tried restarting almost 15 times to the same result. Now it just hangs there indefinitely in a state of loop. I powered on the pc this morning and it goes to the Windows black screen with blue logo and continues to the black screen with circle dots.

I have been running Windows 10 through a Mac Mini Bootcamp partition for the past 3 years. I was unlucky that this happened during the midst of classes, but fortunately was able to recover all files and user data. If your external hard drive is NTFS formatted and cannot be written to, install the free trial of paragon NTFS drivers for mac.įrom hereon, if you do need Windows, you can either try to repair the Windows partition using Disk Utility or delete the existing Windows partition and create a new partition using bootcamp and fresh copy of Windows + drivers. Backup by either connecting an external hard drive or by copying files from the windows partition to the mac partition. In particular, backup the Users/ Name folder, which contains your desktop, documents, and downloads. These can be found in the devices tab through the Finder application on the mac taskbar (probably named Windows or Windows partition). From there, make a backup of all your files on the Windows partition. If you are unable to see the boot menu, try connecting another wired keyboard (if this still does not work, it could be due to a hard drive failure). Select Mac OS using the keyboard arrow keys and press Enter.

Hopefully, you will be presented with a boot menu asking you whether you would like to boot in Mac OS or Windows. Continue to hold the Options/Alt key until the mac has fully booted. Press and hold the Options key (apple) or Alt key (windows) while simultaneously powering on the mac by pressing on the power button. Shutdown the mac by holding the power button for ~10 seconds. Solution to anyone else having the same problem of a bootloop in the Windows partition of a mac bootcamp:Ĭonnect an external wired keyboard (can be apple or other brand - I used an old acer KU-0355) to a working USB port (I tested power to the port using a USB led lamp). More information about causes can be found here: So it appears that the Windows partition / system files required for boot has most likely been corrupted - Apparently it can happen for no obvious reason and without any warning upon reboot.
