If you go to boot manager you can select usb, it will reboot/(power off, just restart) and boot from usb, at this point you will need a keyboard so powered usb hub is necessary.

yes

yes

Ok. Ntfs should be fine.

You need to change some settings in bios to allow usb boot.

To get keyboard and usb boot support, in bios

Device manager......

System setup........

android.......
Uefi secure BOOT=disable.

South cluster configuration.......
Usb configuration.....
default drd CONFIG=hostmode
Usb VBUS=on.

that's it save changes and exit. Next time you boot to bios you can use keyboard connected via otg to use bios. You can also select next boot device in bios boot manager.

yes

The only way to disable the bootloader error 03 is to re lock it, this is not reccomended as with thlocked bootloader you wont be able to load twrp if anything goes wrong with your android system.

Mine still says secureboot enabled and I able to boot win10 and win to go usb sticks. I would not recomend deleting the keys! But only because I don't know the outcome.

Does your stick boot on another pc?

Yes, I would like to see that too, but there is a few chance that a Windows user come to this topic

Flash Windows 10 BIOS ?

On Lenovo's Product Site they offer the original Windows 10 BIOS to download.
Maybe their is an possiblity to flash the BIOS to Android Version.

They also offer the original Android Source Code maybe somebody can use this information.


Good Luck

I tried this and it started out OK but I messed up. I typed the command to mount in adb shell and it was OK. While I was typing all the x00\ I hit enter at some point while going for the back slash. I now get device or resource busy. I tried to start over and now when I type the mount command I get Permission denied. I tried the mount command after using the su command but the same results. I restored the original system partition from a twrp backup and get same results. Any idea what I need to do besides get better at typing.
