    I recently had Windows 7 run some updates (one of them was the windows 10 app) when they completed my boot camp drive was missing from Startup Disk. I can still access windows via holding down alt at startup.

    This wouldn't be a big issue if it weren't for the fact that I have to install the original GFX card (X1900) to get the boot loader screen to show. As I use Win7 for games this is not a permanent solution. Alternate solution would be a way to get my GTX570 to show the boot loader screen.

    The hard drive still shows in OSX but not as a bootable drive. I can access it and see all the files but that is it.

    I am running:
    Mac Pro 1,1
    2 x 3Gz Xeon
    OSX 10.7.5

    Any help would be greatly appreciated.

    Thanks!

    I have had it a number of times that Windows changed the drive labeling in the partition map. I use iPartition to relabel and restore the assignments.

    Did you have to format and repartition the drive?

    Check out BootChamp. It is an app that recognizes the drive for being a BootCamp drive even if OSX thinks it is not a bootable drive.

    Just out of curiosity, do you have some third party NTFS driver installed? I have tuxera ntfs installed and when the boot camp partition is mounted with that it won't show up in Startup Disk system preferences.

    O yes, that's very likely! I have Paragon NTFS and as soon as I disable that the BootCamp drive pops up in the startup disk selection. BootChamp ignores this, would recommend you to give it a shot :)

    Your Windows partition should have shown, and think you have an option in Paragon, to use it for setting Windows boot volume.

    The Windows Partitions have never shown up for me in Startup Disk if you are not using the included NTFS/FAT32 drivers to mount the partition in OS X. I've used a number of different ones since Apple introduced Boot Camp and none of them work. Its easy to test and reproduce, as bokkow has shown. If you disable the 3rd party driver, it shows up.

    Of course you can still change the startup disk using utilities like BootChamp, or holding down the Option key during startup.

    BootChamp works but it would be nice to get Startup Disk working as well. Thanks!

    I don't have any NTFS drivers installed.

    NO. I used the iPartition utility from Coriolis to correct the labeling of the partition. You can likely also do this diskutil from the command line, if you know how.
