Booting windows 8 in UEFI mode

Notadwocat Lol · Mar 30, 2015

Hello, I have bought a tablet with windows, but there were some issues, hence my windows are coorrupted and I need to reinstall the windws, but i can't find the solution, becouse when i enter the shell and, for example, wrote "map -r", drives(fs0; blk0-blk1), does not contain the information from my SD card.

To change the boot priority would be great.

I have used Rufus for making my sd card bootable.

Appreciate any help, thank you.

Did you try calling Microsoft's customer support?

Notadwocat Lol · Mar 31, 2015

Yes, they redirected me to manufacturers of my device, but manufacturers have not contacted me yet. I researched that to boot from USB stick in the preinstaled windows computer I will have to disable safe boot options, is that true?

oh... it's not a surface?

Notadwocat Lol · Mar 31, 2015

Unfortunately no, but it had windows 8.1 preinstalled.

ToineF · Mar 31, 2015

can you provide a little more info. Who is the maker? model number etc...

Prestigio Visconte 3 is the model's name. more: http://www.prestigio.com/catalogue/MultiPads/MultiPad_VISCONTE_3

If you can boot on windows, try restoring it to factory setting.

The system restore partition is messed up

mount the windows .iso (using power iso or something like that) and just start the setup.exe from windows and it will start installing.

once you are in the eufi, cant you do anything?

Notadwocat Lol · Apr 1, 2015

I can, but, for instance the USB drive is not being listed, what is more when trying to boot from UEFI shell, I get FILE NOT FOUND, even though usb drive contains "efi"folder..

ToineF · Apr 1, 2015

if you have a USB port, trying making a USB key that is bootable.

The USB wont appear if there is no bootable usb key inserted. (my eufi works that way anyway)

Notadwocat Lol · Apr 2, 2015

Yes, for that I tried software "Rufus" and Microsoft usb tool, I tried to boot my pc with that USB stick, everything went smoothly..

Notadwocat Lol :

ah so it worked, right?

Is everything ok now?

Notadwocat Lol · Apr 2, 2015

ToineF :

I can boot on my PC not on the tablet, which is my goal..

Boot to UEFI and change the boot priority. There are details on how to do that here: How to Boot to the UEFI BIOS on any Windows 8.1 Tablet or Device. Then check to see if there is an option for "secure boot". If there is one, disable it. Reboot the device and enter BIOS again. You should now set the boot order. Make sure that you have the SD card plugged in. Otherwise the BIOS won't see it as a boot option.
