May 23, 2015 1:36 PM in response to neil4770by Loner T,What is the year/model of your Mac? Please check System requirements to install Windows on your Mac via Boot Camp - Apple Support for drivers appropriate for your Mac. If you bypassed BCA to install a version of Windows not supported on your Mac, you will have problems.
Please also see Boot Camp: Set the default operating system.

May 23, 2015 4:57 PM in response to Loner Tby neil4770,Hi My mac book is a late 2009 13 inch. I did go through all the recommendations and used Boot camp in OS X. it downloaded the supporting software, partitioned the hard drive and allowed the installation of 64 bit 7 ultimate. I tried to install the supporting software downloaded and that's where I get the error this machine doesn't support bootcamp X64. now the unit boots direct to windows and the apple icon doesn't show. Even when I hold the option button on reboot.
in storage manager of windows, I can see the partition but just cant access it.
any ideas?

May 24, 2015 2:33 AM in response to Loner Tby neil4770,Hi and thanks for the info. I have tried both of the options and nothing changes. When resetting the NVRAM, I don't get the reboot it just carries on to windows.

May 24, 2015 5:50 AM in response to neil4770by Loner T,Do you have a Boot Camp option in Control Panel?

May 24, 2015 6:24 AM in response to Loner Tby neil4770,Hi no nothing there either. I cant even get it to boot from DVD to do a clean install - not that I really want to as I have a lot of data that hasn't been backed up.

May 24, 2015 6:56 AM in response to neil4770by Loner T,Can you install OS X: Installing OS X on an external volume - Apple Support and boot from this external disk?

May 24, 2015 7:57 AM in response to Loner Tby neil4770,Hi. I would need a mac to do that by the looks of it.
I have managed to get into disk utilities through a mac OSX disk and have deleted windows, unfortunately it seems there is no start up disk option for my OS X. and now when I boot I get the message insert boot device and press any key.

May 24, 2015 8:04 AM in response to neil4770by Loner T,You already have a Mac. You can use it to install OS X on an external disk. If you are able to boot from the MAC OS X DVD and run DU, it is possible to fix the Mac when booted from this DVD.
Can you look at the output of
gpt -vv -r show /dev/disk0
Does it look similar to
gpt show: /dev/disk0: mediasize=256060514304; sectorsize=512; blocks=500118192
gpt show: /dev/disk0: Suspicious MBR at sector 0

May 24, 2015 10:50 AM in response to Loner Tby neil4770,Hi and thanks again.
Since deleting windows I have managed to install snow leopard on that partition. from there I can access all my files but still cant boot to my main OS. the output from the command shown is no such file or directory. I am guessing that Windows has written over this to point to the other partition. In older windows it was possible to alter a file named boot.ini is there something in OS X that is similar?
My main partition still does not show in the start up disk choices.

May 24, 2015 1:36 PM in response to neil4770by Loner T,Do you now have two OS X installations? One on the original partition and one with SL on a partition which contained Windows? If you can boot into SL, what do you see in System Preferences -> Startup Disk? Is you original OS X a Yosemite installation?
-
May 24, 2015 1:54 PM in response to Loner Tby neil4770,No I cant see the Yosemite in start up disk only SL and network startup. I can access everything through disk utility.

May 24, 2015 2:04 PM in response to neil4770by Loner T,If it is Yosemite, which uses a CoreStorage volume/volume group, SL knows nothing about it and cannot see it. If you power cycle and hold the Alt/Option key, do you see a Yosemite option?

May 24, 2015 2:22 PM in response to Loner Tby neil4770,No when I power cycle and hold the option key nothing happens just like when I had windows installed..
