I started backing up a Dell Notebook and a PC on which I intend to install the Windows 7 and Ubuntu 9.10. I would have no problem installing only the Windows 7 and applying the Daz Loader, for example, with the following instructions that Daz gave to us: Code: 1. Install windows 7 (Don't enter a serial during installation) 2. Run this as an Administrator (Should prompt you) 3. Click on Advanced Options (Optional as the program will try to best detect the following for you) 4. Choose a matching SLIC and certificate (Dell, MSI, etc.) (Optional) 5. Choose a loader mode (Optional) 6. Click on the install button (Under software mod) 7. Wait for the Loader to work and reboot. Enjoy !!!! But I want to install Ubuntu together with Windows, each one in your own partition. So, I don't know what I have to do, because I think the loader can mess up with Ubuntu installation or vice versa, breaking up the whole system. Is it Ok if I first install Windows, apply the loader and install Ubuntu ultimately? If for any reason, can I uninstall the loader without problems with the two OS installed? What do you recommend? Thanks in advance.
