<div class="ecxWordSection1">
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;">Sorry to hear about the problems with the script. Lasse pointed out the problem with running it on Windows 7 to me earlier this week – it’s going to take some
serious surgery to remove the dependency on the Disk module. </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;"> </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;">In the meantime you should be able to do a normal install from a Windows 8/8.1 USB key onto a SATA drive.
</span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;"> </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;">It should theoretically also work to an SD card if you go into the firmware settings and make the SD card non removable (it’s under the LPSS settings). I has
having some trouble the last time I tried that, but I think my SD card might have been too small.</span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;"> </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;">The installation guide contains a link to the Windows Industry 8.1 trial image that we’ve tested on the board. You get an ISO – mount it and copy the contents
onto a USB key.</span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;"> </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;">Windows 7 would probably install on the system with the 64-bit firmware. To my recollection though Windows 7 didn’t support UEFI on x86 systems.</span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;"> </span></p>
<p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;">I haven’t seen the script make a USB drive unmountable afterwards. Do you see the disk show up in the disk manager when you plug it back in? That said I should
be able to put the registry flag back after I’m done – I’ll file a bug to take care of that.</span></p>
