Morning.

I'm currently battling with a Windows Surface RT running on the old ARM chipset. (The Surface is from 2013)

There is no boot to BIOS/UFEI. So I've had to boot to Windows (8.1 I think) but I can't run FTK Imager lite or command line because they are not signed by Microsoft and the exe's wont run.
I found a dd.exe to try, but same as above again.

Does anybody know or any tools that I can use to get an image of this 32GB eMMC. (Chip off is not an option...yet!)

Any help much appreciated.

Volume+ and power key should get you to the UEFI. If this doesn't work on your ARM tablet you may still be able to boot from USB.

Secure Boot only allows 'trusted' OSs, of which Ubuntu is one of them. You'll need to edit the boot config files from your Kali/Backtrack bootable USB to resemble the trusted Ubuntu ones. Fingers crossed, the Surface you have is set to try to boot from USB first.

Also try Volume- and power key to get to the boot menu.  

Thank you. Maybe it wasn't working because I was trying with a Paladin USB. I'll try with my Kali USB and see if that works. I did try booting with the Vol up and Vol down to no affect.


Thanks.  

Try connecting the Paladin USB with a powered USB hub. That has worked for me in the past - obviously with any Secure Boot etc disabled.
