My device is Dell Venue Pro 11 which came with Windows 8 x64 pre-installed on the SSD.
Previous issues ->
Firstly I installed Ubuntu on dual-boot in the same SSD: after doing that Windows stopped booting, i.e. I was only able to enter Ubuntu.
Secondly I tryed recovering my Windows partition by using Testdisk and other tools for fixing partitions, booted in live mode from a usb stick: after doing that my partition table seemed to be completely gone and so I couldn't enter nor Windows or Ubuntu.
Now I can only booting live operative systems from usb stick (I never tried using a cd). Some of them boot, some others don't, anyhow using a usb stick is the only way I may work on my tablet pc.
Now I'm trying to reinstall Windows ->
I purchased a license key and downloaded the ISO of the upgraded version (Windows 10 x64) which is still compatible with my hardware. I put the ISO in the usb stick, which was configured in "multiboot" mode (I used Yumi for doing that). I switch on the tablet pc and push twice the volume + button to enter the boot menu; I boot from the usb stick and then select the first option to install windows; I click "install".
That's what I get ->
the installation procedure seems to begin, I get the Windows 10 logo and then a blue screen appears; a window appears for a very short time and then the blue screen only remains; I cannot do any operation but moving the cursor only. (Exception: Once I got the window with the installation menu in the middle of the blue screen. But When I rebooted the issue recurred).
Additional attempts ->
I also launched Gparted live from usb stick and deleted the partition where the previous Windows was installed (the whole space in the SSD) and then tried installing Windows;
I also created a new NTFS partition with Gparted in the SSD by using the whole space in the SSD and then tried to install windows;
I also tried putting ISO in the usb stick by using other tools (unebootin, Rufus) and without the "multiboot" configuration;
I also tried using the Windows 8.1 x64 ISO instead than the Windows 10 pro x64;
I also tried changing the bios mode (legacy boot, Uefi, security mode enabled/disabled);
I also tried selecting the usb stick both from the Uefi menu and the legacy boot menu in the boot menu.
Given that, my problem is: How can I install Windows 10 x64 on a UEFI device from a Usb stick? Why I'm having these trouble (blue screen) in an apparently random way when I launch the installation?
