The installation turned out to be pretty easy.
As most projects go, the prep is the most important step. First, make sure that the device is fully charged. I swear the thing doesn't change when it's running. Maybe it's just my device. Maybe I'm imagining it.
While the device is charging, download the 32bit version of the ISO from the Windows Insider site and burn it to a USB drive. I used isotousb. Format the USB drive for FAT32 and make sure that you click the option to create a bootable drive. Oh! Don't forget to grab the activation keys.
You're also going to need some drivers. You can get them from the Dell Venue 8 Pro Product Support page. I ended up using:
There's also an update for the touch screen (Panel Touch Firmware for Dell Venue 8 Pro 5830) but the installer notified me that the touch driver was already up to date after I had installed the Intel Atom A3000 Series Driver. YMMV.
I created a folder on the USB drive and copied all the installers to it.
Then you're going to need a USB hub.Windows 10 didn't come with a driver for the touch screen so you're going to need a mouse. The hub will allow you to have both the USB drive and mouse connected at the same time. You might also need an adapter (like this one) to connect the hub to the micro USB on the Venue 8.
With the device turned off, connect the USB hub to it. Press the Volume Down button and power on the device. It'll seem like the boot stalls until you release the Volume Down button. Then the device will boot into the BIOS setup. Navigate to the BOOT tab. You should see both the internal drive and the USB drive showing as bootable drives. Change the first boot target to the USB drive then save the changes and let the device restart. If all went well, the Windows 10 installer should start.
I chose the Custom Install option and removed all the existing partitions.
After the installer completed, I installed the drivers in the same order that I listed them above.
One note: the only operating difference that I've noticed is that I have to hold down the power button for a couple of seconds to power on the device. Otherwise, everything else seems to be working as expected.
