Q: Win7-32bit on BootCamp won't boot under 10.9

Christopher Murphy suggested I post this as a new thread, so I am doing that.

Hi. I upgraded to Mavericks, and it broke my BootCamp. I have been using FileVault2 and Mtn. Lion before the upgrade. I can see my Windows partition, and I can select it from Startup Manager, but I can't boot into it. Similarly, I can choose it in System Preferences>Startup Disk, but booting to it does not succeed.

    Like I said, I don't need to see it, let alone see it twice. You need to do this on all of the disks to see if any others have boot loader code. You should get results with just zeros, like this:

     

    00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

    *

    000001b0  00 00 00 00 00 00 00 00                           |........|

    000001b8

     

    In which case that drive does NOT have bootloader code, which is good. If you find one with boot loader code then tell us.

    That is what I did.

     

    The others did not have boot loader code.

     

    I apologize for not meeting your expectations, and I appreciate the help.

    So either the boot loader code in disk1 is broken and needs to be fixed. Or the firmware is still confused having so many drives connected for some reason, or maybe it's worth trying some voodoo and zapping the pram a couple times.

    Zapping PRAM was nugatory. There were two iterations.

     

    There was no change in the failure to boot behavior of the Windows partition, whether attempted from Startup Manager or from System Preferences>Startup Disk.

     

    Black screen, with flashing underscore cursor top left corner, in each case.

    There are a couple of similar situations for a blinking cursor, which may indicate driver issues (because of driver differences between where the W7 was originally installed and the new hardware where you are trying to boot it from). 

     

    There is one here - https://discussions.apple.com/thread/4936761

     

    Christopher has also mentioned using bootrec.exe.

     

    Can you try building a USB with Bootcamp drivers and a Windows7/32-bit ISO on another machine. You may not need it for recovery or anything else, but just executing bootrec.exe. Disconnect all other external devices when using such a USB.

    Hello all, and thanks for all of your help!

     

    I described to the contents of this thread to a friend of mine who works in IT.

     

    He said "Holy cow, you use Windows so seldom you don't have anything you care about in your Windows installation!"

     

    I said, "Yup."

     

    He said, "I'll be back in town in a week and I'll give you a 64-bit Windows 7 Ultimate with a registration code from the Microsoft Store."

     

    I said, "I accept."

     

    Thanks again, guys, but I am going to cut and run.

    Probably best to zap it and start again with 64 bit

    I just successfully installed Windows 8.1 Update 1 on BootCamp on Mac OS X Yosemite. Here is a step by step I just wrote, hope it helps y'all:

     

    How to successfully install Windows 8, or above, on Mac OS X Mavericks or above:

     

    Requirements:

    1- Windows OS ISO Image file

    2- An 8GBs USB Flash Drive

    3- A good Internet connection as you will need to download the Windows compatible drivers for your Mac

     

    Steps:

    1- Open up Disk Utility and create an additional partition for Windows formatted as ExFat. 100GBs, or above, is recommended as update to the operating system, as well as Apps requiere space on your HD or SSD [This step can be done during Mac OS X's installation process]

    2- Open up BootCamp Assistant

    3- Make sure only the 'Create a Windows 7 or later version install disk' is checked and your USB Flash Drive plugged in and click 'Continue'

    4- Click 'Choose' and select your Windows ISO Image file

    5- Select the USB Flash Drive you will be using during the installation process and click continue to confirm

    6- Once done, restart your Mac and hold down the 'alt/option' key on your keyboard to bring up the Boot Menu

    7- Select the USB Flash Drive named Windows, not the UEFI Boot

    8- Install Windows as you normally would

    * Remember to press and hold the 'alt/option' key, and select the Windows Partition, whenever the installation process requires your Mac to restart
