Windows 10 Tech Preview on a HP Stream 7 device

Posted on by

You will need:

  • A USB Storage device  (4GB will do) (OTG storage wont work for this, because you need a USB keyboard plugged in too)
  • USB OTG adapter cable
  • USB keyboard (and optional mouse)
  • USB Hub (so you can use a keyboard and your USB storage at same time)

Download the following:

  • Downloaded the latest publically-available 32 bit Windows 10 TP build 9879 ISO from here:
    • http://windows.microsoft.com/en-us/windows/preview​-iso-update?os=win10
  • To create a bootable USB drive with 32 bit UEFI support, download the free Rufus utility from here:
    • https://rufus.akeo.ie/
  • HP Drivers for Wifi. TouchScreen.  Bluetooth.  http://support.hp.com/us-en/product/HP-Stream-Tablets/7439994/model/7482041/drivers
    • Goodix Touch Controller Driver
    • Wifi. Intel Combo drivers.
    • The Realtek RTL8723BS UART Bluetooth Driver (SP69353.exe)

Instructions

Make the bootable image

In the Rufus options, use “FAT32”, “GPT Partition Scheme for UEFI computer”, and “create a bootable disk using ISO Image”, and point it towards your ISO.  I used a 16 GB microSD card in a USB 3.0 card reader, but you can use a USB thumb drive also.  It created the bootable USB in about 5 minutes.

Put the HP drivers on the bootable USB storage too

Make sure you download all the HP drivers, and have them on a USB thumb drive – the internal microSD card reader and the WiFi won’t be working until you install the drivers!  Install the Intel combo drivers first, then the rest of the drivers in any order.  The touchscreen driver wouldn’t run for me after the unpack step – just go into Device Manager and update the driver manually, and point it to the unpacked driver .inf files.

Setup and Bootup

Now I actually forgot to disable Secure Boot in the BIOS, but the install worked just fine.  Plug in your OTG cable to a USB hub, and plug into the hub a mouse, keyboard, and the USB drive (your touch screen won’t work during and after the Windows 10 install until you install the Windows 8.1 HP drivers.)  Boot into the recovery options (power+volume down), choose UEFI USB drive (if it’s not listed as an option there, something didn’t work), and the Windows 10 install will start.
After you click Install Now, make sure you choose Advanced, and you should be able to delete all the current partitions on the SSD – you should have about 29 GB free.  (Make sure you created a separate 8.1 recovery USB drive from within Windows 8.1 before you did any of this in case you want to go back to factory stock, because you’re wiping out the recovery partiton!)  Point the installer at your now blank SSD, and away the install goes!

Since I had no WiFi during the Windows 10 install, it didn’t offer to set up using a Microsoft account, so you’ll have to set up using a local account.  Once you have the drivers installed, you can convert to a Microsoft account, which will then sync a lot of your settings from when you had 8.1 installed on it, which is nice.
