I own Acer S1002 "laptop". Its one of those 2 in 1 tableto-laptop devices running on Atom CPU. It will only install Windows in 32 bit version because it has a dumb**s 32 bit EFI bootloader.

When installing ElementaryOS 5.1 everything (almost) is peachy. It installs it boots - few minor issues.

When installing ElementaryOS 6 it installs but after a reboot I get an EFI shell.

Upon closer look the EFI partition on 5 contains:


ubuntu (folder)



While ElementaryOS 6 only shows 64 bit files.

I tried copying files listed above to the EFI partition of the ElementaryOS 6 installation - that did not fix anything.

Machine's bios does not allow to disable UEFI / enable legacy boot.

Chrooting into installation and installing refind does not help...

Tell me Gandalf, what I must do now?

Please do not leave me with Windows 10 32 bits as my only option :)

Kind regards.


Solution below. Warning, beyond here there be dragons.

Ok I am sorted... I will show you how but do so at your own risk. You need to know at least basics and I am not taking any responsibility if you fubar...

First what I did was I've installed ElementaryOS 6 and rebooted.

I rebooted into ElementaryOS 6 LiveUSB.

Next I've followed a prompt and went into the "Demo" mode.

In demo mode I've connected to wireless.

Then I've opened a terminal and ran:

sudo su

mount /dev/mmcblk1p4 /mnt

(mmcblk1p4 is my /)

mount -t proc none /mnt/proc/

mount -o bind /dev /mnt/dev/

mount -o bind /sys /mnt/sys/

mount -o bind /run /mnt/run/

mount /dev/mmcblk1p1 /mnt/boot/

(mmcblk1p1 is my /boot)

mount /dev/mmcblk1p2 /mnt/boot/efi/

(mmcblk1p2 is my /boot/efi)

chroot /mnt

apt update && apt upgrade && apt dist-upgrade && apt autoremove

(ignore messages about not being able to write the log)

apt install efibootmgr grub-common grub-efi-ia32 grub-efi-ia32-bin grub-pc-bin grub2-common mokutil secureboot-db

(You will be asked to type in a phrase to continue the installation)

apt autoremove

grub-install /dev/mmcblk2




After reboot I was finally able to boot :)


Kind regards.
