I am downloading Windows 7 Ultimate RTM as we speak, with the intention of installing it on the HP Mini 5101. I will create a bootable USB from the Windows 7 ISO and then install from there. I’m not sure what drivers will be missing after the install completes. HP hasn’t released any Windows 7 drivers yet, so I’ll let Windows Update find what it can after the install. I’ll probably try Vista drivers and utilities for any devices not working at that point. Have any of you installed Windows 7 on the 5101 yet? How did it go?
