Apple Event: May 7th at 7 am PT
Have been on OS X Yosemite, no problems with Bootcamp, after updating to v10.10.3, BOOTMGR missing-unable to get in to Bootcamp...Is there a way to do start up repair from win 7 install disc or copy/replace bootmgr in Bootcamp? Files can still be seen in Finder.
MacBook Pro, OS X Yosemite (10.10.3)
See the USB as an option...will boot, can start repair...can only ask to reload drivers at bottom...do not know what to do. will not show boot camp drive as option to repair.
Can you search the USB for bootrec.exe?
can get to system recovery tools...could not find bootrec.exe...where should it be? Sorry
Do you see an option for Command Prompt as mentioned in http://windows.microsoft.com/en-us/windows/what-are-system-recovery-options#what -are-system-recovery-options=windows-7 ?
If yes, bootrec.exe should be in your path. Please see https://support.microsoft.com/en-us/kb/927392.
Confused...from USB...at Command Prompt X:\ would you please list commands I need to use...can not get this to work (or) may be possible to get to Windows Boot Manager but do not know what to do (last time there...F8 would not work)...in what order. I appreciate your help...this is totally frustrating to the unskilled.
If you are on X:, try dir/s/p bootrec.exe ?
Have now tried bootrec /fixboot...said operation completed successfully, then did bootrec /rebuildbcd...said there was a windows installation on C:\...add installation to boot list? Answered yes...got "the requested system device cannot be found" Do you have any other suggestions and/or what is my next step?
Do you want to consider re-installing Windows on top of the current installation as is? It will save your current Windows to Windows.old? Make sure you choose the appropriate install, if you go this way.
After reinstall will all other data be available or better to new install and add backup...also would repartitioning allow c: to be seen and fix boot.
what is the safest and best backup method to use under the current conditions with bootcamp...this is a real pain...Thanks again for your help

The safest method at his point is to use UNIX dd command and make an exact replica of the BC partition to an external disk.
I have this problem too. I'll reinstall Windows because it seems way too complicated for me! I hope Apple will fix this because it must be a pain ** *** *** for professionnals.
