Windows 10 laptop, no USB, keyboard and mouse

Solution 1:

1. Don't panic, your data is still there and laptop can be reset and will be good as new. In fact, it will be better than new after reset ;-)

2. If your primary objective is not losing data, stop immediately with any attempts to repair/reset anything, as well as trying to retrieve your password or boot from another Windows USB stick. Make a backup of your data first, experiment later.

3. The easiest way to make a backup is to boot from a bootable Ubuntu USB stick, connect an external hard drive to a USB port and copy all your files to the external hard drive. Which you then disconnect and store in a safe place before performing any further repair actions. You say you have an "Ubuntu USB stick", but are you sure it is bootable?

4. The easiest way to make a bootable Ubuntu USB stick is by using software called Rufus on a different Windows computer. You can also create a bootable USB using MacOS.

5. If your "broken" laptop has a 64-bit processor, you can use any Windows or MacOS computer to create a bootable USB. However, if your "broken" laptop is 32-bit, you will need to find another computer running 32-bit version of Windows. Or install a 32-bit version of Windows on that computer first (physically or in a virtual machine).

6. For bootable Ubuntu USB stick for backup purposes I recommend using an older version of Ubuntu, particularly 16.04 LTS 32-bit version. The reason is because it will run almost guaranteed on any laptop, no matter 32- or 64-bit, fast or slow. This Ubuntu version is still officially supported. Get it from here: http://releases.ubuntu.com/16.04/ , make sure you download 32-bit version to create a USB stick from it.

7. To actually create a bootable Ubuntu USB stick, simply follow this easy official step-by-step tutorial: https://ubuntu.com/tutorials/create-a-usb-stick-on-windows . The first section of the tutorial gives you an option to switch to a tutorial for MacOS.

8. Once you have created a bootable Ubuntu 16.04 32-bit USB stick, you insert it in your "broken" laptop and switch it on. Then go to BIOS. Find a setting that looks like "BOOT PRIORITY" or "BOOT ORDER" or "BOOT SOURCE" or something similar, and put your Ubuntu USB stick on #1 spot in the list. Reboot. Wait. Ubuntu installer will start up. Choose "Try Ubuntu". Now Ubuntu interface will start up. This way, you can safely copy all your files to an external HDD.
