Therefore you had better make a fresh backup of the operating system in that drive (Windows) before following this route.īoot into the live USB drive and use the installer to install Ubuntu into your SD card or another USB drive (best with a fast USB 3 drive with at least 16 GB).Yes, the command you're thinking of will certainly produce a disk image file that can be written to another similar disk.

and after the installation is finished, restore the flags according to the note on paperīut I have never used this method, and cannot guarantee that it will not damage the internal drive.

Remove the flags on EFI system partition of the internal drive.

check the flags on EFI system partition of the internal drive (in linux with the tool gparted, in Windows there are also tools for it).

If none of these methods work, you can borrow another computer for this task, a computer, where you can disconnect the internal drive.

It is often but not always possible to do via a UEFI/BIOS menu.Create a live USB drive by cloning from the Ubuntu iso file to a USB pendrive, which can be small and cheap, for example a USB 2 drive with 4 GB.community/Installation/FromUSBStick#Notes_about_speed If you fail to boot from your SD card, you can try with an USB adapter, but you have better chances to succeed, if you get a fast USB 3 pendrive with at least 16 GB according to this link, Some computers (far from all) can boot from an SD card, which is connected via a built-in slot (typical in laptops).But some computers and adapters are not compatible for booting. Most computers can boot from an SD card, which is connected via a USB adapter.But it is 'more difficult' for the computer's early stages during boot, the UEFI/BIOS system, to see the SD card and be able to boot from it.

In most cases the running operating system will see and read an SD card.
