Last month to catch the Win 8 just launched when bought a new notebook computer, pre-installed "Win 8 Simplified Chinese version", and hard disk partition mess. So immediately bought a set of campus pioneer version of Win 8 Professional Edition, ready for a new installation, but will ISO copy into the U disk boot after booting the display key does not match, cannot install. Think about it. Did you ever listen to win 8 to write key into the BIOS, maybe this time directly from the BIOS read key?
When the BIOS is turned on, the version is "Win 8 std", which means everyone knows it. It seems to be a new installation to bypass this pass.
Install Win 7 when a netizen proposed by modifying/resource under the Ei.cfg file to achieve the installation version selection, inspired by this search win 8 can also do so, just ei.cfg must be new.
To install the new win 8 Pro retail version from a U disk or burn DVD, simply create a new ei.cfg file under/resource and enter the following when you open it:
[EditionID]
Professional
[Channel]
Retail
