No, this is not a guide how to wreck someones computer nor a call to kill Windows… But for having troubles with Windows you might want to try that… at your own risk.

This is a simple partition scheme, to be found on some notebooks, preinstalled. The linux partition was made by the user after resizing the main partitions. The hidden volume is a rescue disc like thing for reinstallation, including the drivers. And those are the files I would like to rescue – so what’s the problem?
Well… the ‘Hidden HPFS/NTFS’-Partition is set by Windows itself. You can change the partition type from 0x17 back to 0x07, but at the next windows startup it gets set back to 0x17. In other words, you can’t access the files in windows.
The last thing that helped me out was removing the linux partition and rewriting the mbr as neither diskpart nor hacking HKLM/System/MountedDevices was able to fix the problem.
