Windows 10 install fail with “Modern Setup Host” error
Problem
Trying to install Windows 10 Technical Preview Build 9926 on my Dell Venue 8 Pro with Windows 8.1 and gets the Error: “Modern Setup Host has stopped working”.
Cause
It appears that you should make sure your system has a
certain amount of hard disk space available before
installing
16 GB available disk space (32-bit) or 20 GB (64-bit).
Solution 1
Having this much free space on a Dell Venue 8 Pro is
impossile so one solution is a fresh install by booting from
a USB key containing the iso file content extracted with a
software like
rufus.
For Dell Venue 8 Pro users: Don’t forget to format
the key as FAT32 and to install the 32-bit version of Win10,
then press and HOLD the volume down button until the DELL
logo screen shows ENTERING BIOS in order to enable boot from
USB.
I had an issue with this solution as touch refuse
to work during setup, you might want to try with a keyboard
and a USB hub.
Solution 2
Unpack the content of the .iso file onto a micro SD Card then plug it into the Dell Venue Pro, open the SD card and run setup.exe from it. The in-place upgrade from Windows 8.1 worked for me. Touch and Wi-Fi worked at first try without any trouble.
