I found one post online describing a way to reset the Bios by shorting a pin on the Winbond FlashRAM chip but that too did not work. There is no jumper inside, no coin-cell battery, and disconnecting the built-in battery packs didn't work." So now I have no way of running anything at all.Īs noted in my original question, "The tablet has no Reset button. But since I can't move left/right (only up/down), I can't get to it. The first OS where the Linux iso should be is instead an empty box (which is auto-selected after 10 seconds reporting "iso not found".) Windows is the second icon on the menu. The "menu" is a horizontal row of three icons. It installed a Boot Menu with no touch-screen support.

I thought I finally found the answer with "WubiUefi", a new UEFI version of "Wubi" that is supposed to allow you to install a Dual Boot of Linux along-side Windows on the same computer.īut it didn't work. UEFI has such limits as well, making it doubly hard to do what I needed.Īfter a bit of research online, I found a number of links reporting that it is possible to reset the Bios from Linux, so I attempted to install a dual-boot of Linux, but this too is almost impossible without a USB boot drive. Windows (especially Win10) goes to great lengths to prevent nearly all low-level access to the system through it. I also attempted to Flash the Bios from Windows but that too failed. The furthest I got was to clear the RTC (which I believe is just the first 14 bytes of the CMOS.) I was (past tense) able to log into & use Windows using the on-screen keyboard, and I found software that claimed to allow you to reset the CMOS from within Windows, but it didn't work.
The Volume rocker acts as Up/Down and the Power button acts as "Enter", but there is no way to move left/right to navigate through the menus to get beyond the first page. Using (basically) the same procedure on a Win10 tablet simply gets you into the AMI bios (Volume Up + Power at startup.)
Unfortunately, the instructions you provided only apply to an *Android* tablet. So I am unable to navigate the Bios even once I get in. This entire mess began attempting to find a way to boot from a USB flash drive, and in the process, I inadvertently disabled the XHCI controller, disabling my USB ports (and anything that needs them like my detachable keyboard.

So you cannot make any changes in BIOS like a boot drive priority change? That would have been my answer and then try and boot from a USB drive loaded with an ISO Windows 10 burn you did from the license. Following the reset, the device should boot up and go through the initial setup process again as when it just came out of the box. Use Volume - to select "Yes - delete all user data" and press the power button to select it. Use Volume - to select "wipe data / Factory reset" and press the power button to select it. >B) List of options in the top left of the tablet screen. You should then see the screen shown in item 'B' If this happens simply let go of volume + and press it one time.

>A) Screen appears with only an Android mascot in the background. Continue holding Volume+ until one of two screens appear: While still holding the Volume + button, press the Power button until the screen illuminates and shows Insignia. If the battery dies during this process the device could be damaged. Ensure the tablet is connected to the charger and has at least 45% battery left. If you would like to go ahead with the factory reset, follow these steps:
