Hello!
I did something terrible to my tablet, I converted the partition from GPT to MBR in a desperate try to install windows 7.
Now tablet is not reading any usb I plug in, and of course I cannot format disk again because it doesn't recognize anything, always booting at uefi shell.
Anything I can do to fix it?
Thank you so much!
try entering your tablets bios (you will need to check your tablet manufacures instructions usualy on their website for how to access the bios)
and change from UEFI to legacy
iirc usb devices will only boot from legacy bios.. at least mine does
you can change the disk type from MBR to GPT using the commandline (DOS) using diskpartassuming you can either boot to windows or the windows recovery environment from USBDVD see here (iirc this works with w7 and up)
Change a Master Boot Record Disk into a GUID PartitionTable Diskonce done switch back to UEFI
imho if your not sure what your doing you may be better off wiping the disks and starting again

But my tablet don't have a legacy option :/.....
I can't enter on windows, neither on recovery, bios always booting the uefi shell, and every usb I plug (with windows on it) tried w7,w8,w10 .. not recognizing any usb.
It would be helpful to know the brand and model number of your tablet.

The brand is spanish, is UNUSUAL 10W.

There is a recovery image (I think - Mi español no es muy bueno.) in the downloads section at the bottom of the page.

The trick is getting it on your tablet - is there any data you need on the device?
You might try using Rufus to create Windows Install Media (Win7, Win8, or Win10) from an ISO. Create the flash drive as a GPT / UEFI boot.
I don't know if that will get you to the machine or not, but it's a thought.
Fixed! I upgraded my bios and now USB are recognited !
Thank you all!
