Non-System Disk. Press Any Key To Reboot


I have an old Macbook Pro that dual boots OSX Lion and Windows 7.

Suddenly now if I try and boot Windows, I get this message: Non-System Disk. Press Any Key To Reboot

I can't actually insert my Windows 7 disk because my cd drive is broken and at the moment I don't have an external disk drive.

Is there any way of fixing this by maybe burning the Windows 7 CD to a USB or something like that?

Edit: Just remembered, I can actually access the Windows 7 files through the mac side and I think I can write to it... If Windows is having a problem booting could I try and add/edit/replace the necessary boot files to Windows?


Thanks for your time,
Zak
 
You won't be able to write to the NTFS partition unless you have something like MacFuse that gives you the ability to do so.

If you could write to the NTFS partition, I don't know where you'll start to fix the boot problem.

If you do get hold of a Windows 7 installation disc, it does have a repair tool for those who are having problems with booting. If that fails, you can always do an upgrade install over your existing installation. It will keep your files and programs intact and just replace the system files, but doing so would mean you'll have to re-run Windows Update to get it back to the latest patched version.

Terminal, type the following and post the results. Please format your results in the reply window by highlighting the text, and clicking the # button in the toolbar to add code tags.

Code: 
sudo fdisk /dev/disk0

Code: 
sudo gpt -r -vv show /dev/disk0

First command requires admin authentication (password). Both commands are read only commands and make no changes to the disk.
