I have a cloned drive as a backup and my computer is stolen. This computer was probably MacBookPro 11,2.

Now i have an old MacBookPro 6,2, i installed my backup drive as an internal drive to this one.

I can boot to my old OSX Sierra and happy about it.

The second partition has a Windows 10 installation in it. I can't see this partition in option-boot screen. I can reach my Windows 10 partition from OSX.

How can i install or modify the necessary software to make this partition bootable again? I know i need the drivers for this particular computer and i have downloaded them from boot camp. If i can boot to my partition i install them and continue using my old operating windows, am i right?

Thank you.


Note: There is no guarantee that if successful, Windows 10 will remain activated on the Mac. In other words, you may need to purchase a Windows 10 license for your Mac.

The Windows you wish to restore to your Mac used the EFI boot method. Since the drivers you have downloaded require a BIOS boot method, you will need to convert the restored Windows from an EFI boot method to a BIOS boot method.

You will need to make sure your internal drive is use a Hybrid partition scheme. See this answer for details.

You will need to boot the computer using a Windows 10 DVD, open a Command Prompt windows and enter the following commands.

Note: You can open a Command Prompt window, by pressing the shift+F10 key combination after booting from the DVD.

bootsect  /nt60  c:  /mbr
attrib  -r  -h  -s  c:\boot\bcd
del  c: \boot\bcd
bcdboot  c:\windows  /s  c:  /f  BIOS

Note: You can ignore any error messages produced by the attrib and del commands.

After booting to Windows 10, you should install the Windows Support Software that you downloaded from Apple.

  • Thank you very much, i will return to this answer if i happen to be in the same situation again. – Ali Somay Aug 15 '18 at 8:40

I found out that the CCC (Carbon Copy Cloner) which cloned my drive formatted the cloned windows partition as HFS so i think it is impossible i will reinstall windows 10. No answer needed, thank you.

  • You will probably need to burn the Windows 10 ISO to a DVD in order to reinstall. If this is not possible, please post a comment. – David Anderson Aug 9 '18 at 18:36
  • I didn't use boot camp to install windows 10 but unetbootin, i installed it and then the drivers (i guess they are for windows 7 or 8) i started to get regular unpredictable restarts in windows 10. Maybe the drivers are not working properly. I will install Windows 7, try my luck. – Ali Somay Aug 10 '18 at 5:55
  • The proper drivers for 64 bit Windows 7 and 10 can be found at Boot Camp Support Software 5.1.5621. You are aware that you must install a BIOS booting version of Windows? – David Anderson Aug 10 '18 at 7:12
  • Yes thank you. I did install Windows 7 from optical drive and it works perfectly. – Ali Somay Aug 13 '18 at 9:01
