What I have tried:

  1. I have tried using dd and Ubuntu startup disk maker to make a usb installer, but even I choose boot from usb, my computer still directly boot into win10. I don't know why.

  2. I have also tried build a uefi bootable usb by the accepted answer (1st command line method) in this link, but it did not work.

  3. I have also tried to build a uefi usb under win10 by following this link, and I also disabled the secure boot option in bios, however system just won't boot from usb.

  4. It seem that I have a 32bit UEFI(I am not sure though, the reasoning is that my processor is intel atom z3736, but my win10 is 32bit, someone know how to check this explicitly please tell me), and it is quite troublesome to deal with 32bit UEFI, according to this link.

One thing to mention is that the iso is 16.04 LTS of LUbuntu...

Previously I have successful installed Ubuntu on my pc using the above two method, what's the difference and how to fix it?

the bios info:

  • You will need a powered usb hub (must be powered) plug a mouse, keyboard and usb stick containing the Ubuntu install media in to the hub and boot up. – mik Mar 2 '17 at 12:01
  • Note that no hardware is Win10. Hardware can, however, run Win10. – ChemiCalChems Mar 2 '17 at 12:29

According to many articles, install ubuntu on a UEFI 32 bit system with 64bit cpu is troublesome, including the official sites, see the first item.

However, Debian is a savior and many people yet don't know this, including me. Salute to their developers! The latest Debian support 32bit & 64bit UEFI very well. You can see these two posts: first by intel and second by Debian developer.

To install it, you can download the latest iso image here, and make an usb disk following the documentation-4.3.1. Other method using dd or ubuntu startup disk creator should also work (I didn't try). After this, you need to choose to boot from usb.

According to this post, you need to be careful with your downloads if you have a similar situation as mine:

If you want to install a 64-bit system with the 32-bit UEFI support, make sure you use the multi-arch amd64/i386 netinst or DVD. Otherwise, any of the standard i386 images should work for a 32-bit only system.

Please inform me if Ubuntu or other system has this support, I would like to try!

disclaimer: I didn't test the drivers etc... Just able to boot into the usb and install the system..

  1. first build an start up usb disk using the method described here.

  2. because we need internet access during the installation, we need to make our wireless driver to work. This is the most difficult part.

    • download the source from this repo
    • using the method described in this post to download all the packages needed to install build-essential and linux-headers-generic
    • build and install the driver using: cd rtl8723as make sudo make install sudo depmod -a sudo modprobe r8723bs
  3. Install the system with wifi connection.

  4. The installation fails with the error: grub-efi-ia32 package failed to install into /target/. Without the grub boot loader, the installed system will not boot. Damnnnnnnnnnnnnnnnnnn!
