    <![CDATA[<strong>Author:</strong> <a href="https://forum.asrock.com/member_profile.asp?PF=8052">jbmerrill</a><br /><strong>Subject:</strong> 9072<br /><strong>Posted:</strong> 04 Jul 2018 at 1:56am<br /><br />I was once able to boot from install media, but am not able to now and don't know why.  <br /><br />I'm trying to get the latest windows 10 insider preview (1803) up and running, but the upgrades always fail and I was attempting to do a clean install.<br /><br />Booting from dvd immediately fails and bounces back to uefi boot menu, and from flash drive it freezes after windows logo.<br /><br />I'm using RAID and gpt disks, and want to be sure to install in uefi mode.  i have tested my media on another computer, so I don't know why this doesn't work.<br /><br />Windows setupdiag setupdiagresults has following error after upgrade attempt:<br /><br />error:  setupdiag reports fatal migration plug-in failure.  plug-in name=microsoft windows directoryservices adam client\adammigrate.dll, migration operation=ipostapply-&gt;postapply, plug-in error: 0x00000065<br /><br />Any advice is appreciated.  Thanks.<br /><br /><span style="font-size:10px"><br /><br />Edited by jbmerrill - 04 Jul 2018 at 2:12am</span>]]>
