Until DELL releases known good WinPE10 drivers for this model, we will need to build a KBE with very specific drivers.
1- Download DELL's WINPE10 driver pack from here:
http://en.community.dell.com/techcenter/enterprise-client/w/wiki/11530.winpe-10-driver-pack
(Version A07, ID K72DP, Date 01/09/18, Size 94MB)
2- Extract CAB file to a local folder. We used 7zip, if you see a Payload error, please ignore it.
3- Go to the folder \storage\mtwv3_a00-00\windows10-x64\iaahci.inf\5.2.0.1194\
4- Remove the files named "iaVROC.cat", "iaVROC.inf" and "iaVROC.sys"
5- Download the attached zip file, and extract them to \storage\mtwv3_a00-00\windows10-x64\iaahci.inf\5.2.0.1194\
6- Copy Storage and Network folders from your device to the SDA Samba share,
\\YourKBOXIP\drivers\kbe_windows_x64\
7- Make sure those are the two ONLY folders there
8- Open KBE Manipulator, and create a new KBE with that tool. See: https://support.quest.com/download-install-detail/6084577
You could use this same drivers for \\YourKBOXIP\drivers\drivers_postinstall\dell\windows_10_x64\precision 5820 tower\ , But you will need to add missing ones (video, audio, chipset, SDCard reader, etc.)
Contact Quest Support if you have any questions.
NOTE: The Version A00 of the driver pack is the same one DELL has as of 3/19/18, these will produce a Blue Screen Inaccessible boot device.
