Not able to login, not able to repair, endless problems, so I bought a USB drive (stick) and wanted to boot the old machine with Linux

Down to buisiness, ok…

Rufus is widely considered to be the fastest and most reliable tool for the creation of a bootable USB. It also supports UEFI (“Unified Extensible Firmware Interface”), a new mainboard firmware that replaced the old BIOS and can already be found on almost all newer computers. From Windows 8, it’s also possible to install “Windows2Go” as a portable operating system on an external storage device with Rufus.

Operation of the tool is simple:

Press select, and pick the iso.

Some files could be missing for Rufus to make the image, press ready and you will be prompted to download them, the press the recommended.

All data will be destroyed.

Then is is done.

Close and eject the stick.

Now insert the stick in the destroyed windows 10 machine, start the machine, the go to Advanced options->UFEI Firmware Settings, it will then restart and go to boot menu.

Then go to boot and change the >Secure Boot to the stick, in this case->

UFEI> SanDisk, Partition 1, after that press Boot Override, the machine will launch the OS from the stick.

All your files from windows are still there and you are now running Linux.

Display all information.

uname -a

Information

Normal Live OS on portable media (cd/dvd/usb-stick) is normally “read-only” – – no changes are saved (like added bookmarks, programs installed etc.)

A CD/DVD or Usb Flash-stick that has a “perisistent” version of Ubuntu is one that allows the user to modify the “live-OS” (desktop, etc.) and have the changes saved, so upon next login, you will boot into the updated Ubuntu with your changes in place.

Normally, IF – repeat IF . . you installed the Ubuntu OS on your HDD (hard disk drive) in it’s own partition, you do NOT need (or want) to keep the usb-stick inserted. Your system will boot up and give you a screen that allows you to pick which OS (windows, linux, macos or whatever) you want to load and run.

If you did not install Ubuntu correctly to the Hard-Drive, you may just boot directly into Windows (you don’t get the screen asking which OS to load).
