Reset Asus ZenBook laptop

This page describes how to reset the Asus ZenBook to a clean state. (i) The default configuration provided by Asus is full of non-useful software, trials and non-required stuff.

By following this guide all the default programs and data will be wiped out! You'll end up with a clean Windows using the official ISO image + dual boot (optional)

Everything below has been tested on an Asus ZenBook UX510U


Before starting the clean-up you must:

  1. Start the new laptop with its default configuration.
  2. Connect your PC to Internet
  3. Register hardware and software (see next chapters)
  4. Download ISOs and tools


Hardware registration

Register laptop for warranty

Software registration


To check activation status in Windows 10

  • select the Start button
  • select Settings > Update & security > Activation

If Windows 10 isn’t activated on your device, see Get help with Windows 10 activation errors for more info.

Get Windows 10 installation USB drive

Download Windows 10 ISO

Get your windows version and key

The key is not displayed in Windows. You must use a 3rd party tool to retrieve it. I recommend ShowKeyPlus

Download Windows ISO

  • Download the [1] Microsoft Windows 10 download tool]
  • Select create installation media for another PC
  • Download the ISO file

Setup bootable key

Prepare bootable key

  • Download the utility to create a USB bootable key RUFUS
  • Launch RUFUS
  • Create a new bootable disk using the following parameters
  • Partition scheme: GTP partition scheme for UEFI
    • File system: FAT32
    • Select the ISO file
    • Click start ... and wait

BIOS configuration for USB drive boot

By default you're not allowed to boot on USB drive. To overcome that problem you must adjust some settings in you BIOS.

BIOS access

To access BIOS: press F2 and keep it press on boot until you see the BIOS.

BIOS configuration

1. Set administrator password

  • You must set an administrator password (mandatory)
  • You have to save & exit then come again to the BIOS later...

2. Disable security

  • Go the Advanced mode (F7)
  • Security Settings
    • Set Secure boot control to Disabled
  • Boot Settings
    • Set Fast boot to Disabled
    • Set CSM support to Enabled ==> the screen should change upon activation
  • You have to save & exit then come again to the BIOS later...

3. Choose boot device

  • At last you can select a boot device from the BIOS. The USB drive should appear.

Windows re-installation

Partition setup

Re-install windows on the SSD partition.

!! In case of issues please read the next chapter !!


(i) For dual-boot you can create partitions for Linux during the installation.

  • Windows partition = 70Gb (Primary) [76 022 Mb]
  • Linux partition = 37 Gb (Primary) [37 888 Mb]
  • Swap linux = 8192 Mb (Primay)

Windows will create the boot loader partition, say yes to authorize windows to create additional partitions.

Fixing GPT issue

If you have the following error: windows cannot be installed to this disk. the selected disk is of the gpt partition style

  • You need to open a terminal during installation: Shift + F10
  • Launch diskpart
  • Type list disk
  • Select the SSD disk number select disk 1
  • Type clean
  • Type convert gpt
  • Type exit


Disable fast startup


  • Go to Control Panel > Hardware and sound > Power options > On the left, click on Choose what the power button do
  • Click on the shield to enable administrator settings Change settings that are currently unavailable
  • Under Shutdown settings > uncheck Turn on fast startup box

Useful programs

Install windows normally with your favorites programs.

Configuration tricks

Don't forget to set your TEMP directories to the DATA HDD. This is one of the key point to use a small partition for windows.

Linux setup

Download *Ubuntu ISO

Go to Ubuntu website and download the ISO you'd like to use.

I'm using Xubuntu

Create bootable USB key

Use UNetBootIn to put the ISO image to create a bootable USB key.

Mount Windows and Data partitions

To mount the NTFS partitions you have to:

  1. Create the target mount points
mkdir -p /mnt/windows
mkdir -p /mnt/data
chown -R guillaume:users /mnt/*
chmod -R 777 /mnt/*
  1. Get the UUID of each partition using ls -ld /dev/disk/by-uuid/*
  2. Edit the boot file /etc/fstab

!! Adjust the UUID to your own values + adapt the partitions disk and number to your actual configuration !!

# / was on /dev/sdb2 during installation
UUID=e2504785-deae-4d12-ac63-de84dda3c980 /               ext4    errors=remount-ro                                    0       1
# swap was on /dev/sdb3 during installation
UUID=774c5306-a718-4cb7-a874-cec444b78a75 none            swap    sw                                                   0       0
# Data drive (/sda2)
UUID=405A07D75A07C89C                     /mnt/data       ntfs    defaults,windows_names,umask=007,uid=1000,gid=1000   0       0
# Partition windows (/sdb1)
UUID=DAF00EACF00E8EC7                     /mnt/windows    ntfs    defaults,windows_names,umask=007,uid=1000,gid=1000   0       0

You must reboot for the partitions to appear in /mnt/...

Fix READ-ONLY issue

After the reboot the partition might be in a read-only mode - probably because windows uses "fast reboot" option. To fix that:

  • Unmount the target disk:

umount /mnt/data


sudo ntfsfix /dev/sda2

  • Mount the partition again:

sudo mount -t ntfs-3g -o rw /dev/sda2 /mnt/data/

Configure GRUB menu

apt-get install grub-Customizer

# Backup GRUB data
sudo cp -Rp /etc/grub.d /etc/grub.d.ori

# Install application
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

# Lancer l'application
gksudo grub-customizer

Particular points

Everything works fine after reboot under Xubunt 16.10. Wifi, bluetooth, graphics, sound, keyboard shortcuts and light, etc. All is good ! :)

Windows configuration changes

At last, you can set the Windows TEMP to the correct drive letter.

Happy coding to all of you ! ;)
