Cannot read from disk - DD11 Home
I wanted to prepare a new hard drive for installing Win7 on it. So i made a primary partition with DD 11 home (rescue media), set it as active and wanted to install Win7.
All went through well until the Win-Setup rebooted the computer to finish the installation.
But then came only a message: Cannot read from disk, please press Ctr Alt Del.
I had this issue with both a new ssd from OCZ and a new traditional hard drive on two different computers.
Then i thought, ok try it with DD10 and - it worked!
So it seems to be an issue with DD11.

Hello Forellenblau and Frank,
Thank you very much for your posts and your feedback. I will definitely help you.
Forellenblau,
I will forward this issue to our testing lab, so that we can recreate the scenario and find out why this problem occurs. As soon as I have any news, I will provide you with an update.
If you have additional questions, please let me know.
Thank you.

For the moment, maybe. However you'll probably find that after a while, a Windows 7 installation on a partition created with DD 10 will start to show increasing numbers of file system errors. These will rapidly become impossible to manage or fix; you'll find that you can't even back up the partition; and you'll most probably need to re-install Windows 7 from scratch.
DD has many uses, but frankly there's not a lot of point in using it to prepare a partition for straight-forward installation of Windows 7 - as the standard Windows 7 installer now gives a variety of options for creating partitions itself, and this seems to be the safest method. In fact if the disk already has an NTFS partition you want to use, it is probably best to delete it & let the Windows 7 installer recreate one.

@Simon
I know that DD10 is not designed for Win7 but until now i never had trouble with partitions become unusable with Win7. But thanks for your hint. Do you have some experiences with such faulty partitions?
To avoid the 100MB partition the Win7-Installer creates i'm using DD10 to create one large partition on the drive.
I think in the future i will use diskpart from within the Win7-Installer to create a partition, that works very well.
But i initially wanted to use DD11 to create this partition and that doesn't work at all. Im in touch with Anton via PM and i hope there will be a solution soon.
