Windows 10 doesn't boot in bootcamp mode (only boot with parallels)

hi all ,

Today i installed Parallels 11 and windows 10 starts up normal when i use parallels 11 (inside Yosemite)
When i want to startup only with windows 10 using bootcamp windows 10 hangs... (it worked fine before installing parallels) When i uninstall parallels 11 windows 10 still hangs on startup.

Please help

 

Having the same issue with win 8.1

 

Hi all, I reinstalled Yosemite and later with bootcamp Windows 10. After installing Parallels 11 latest edition i had again the same problem. Windows 10 didn't start up anymore with only bootcamp. Windows 10 did only startup under parallels running under yosemite. My laptop is macbook 12 inch.
I hope somebody can help with this...


Thanks

 

Hi, how exactly did you reinstall Windows 10? have you upgraded from 7/8 to 10? It could happen if you upgraded within Parallels, but not directly. This is not proper way.
You should boot your Mac from Windows installation media and run startup repair

 

Hi Marat
How can run startup repair in a MacBook 12.?
Whit the Efi pen drive installation?
Thanks
