Setup - general steps

• Create a backup USB medium (>32GB) using the tool Wiederherstellungslaufwerk
• Shrink C partition, using Disk manager of System Control, add 2 partitions for Linux root and home
• install Debian to WSL-2

Install Linux parallel to Windows

These steps are the ones I remember to have performed to get Linux running.

Please use these with care; the list of actions may be incomplete or may simply not work on any other device.

Disable secure boot on HP Omnibook X 14

• On windows, go to Einstellungen / System / Wiederherstellung
• Then click on Erweiterter Start / Jetzt neu starten (2x)
• The system reboots into BIOS Setup Utility
• Then set Boot Options / Secure Boot / Disabled
• Optionally, you may disable the USB power while sleep+off (This prevents the USB-C hub to drain battery)
• Then Save Changes and Exit
• Then type the displayed 4digit code and press Enter
• Then reboot into Windows

Prepare a USB memory stick

To create a bootable memory stick, download an image from here: https://discourse.ubuntu.com/t/ubuntu-24-10-concept-snapdragon-x-elite/48800

Copy this image to a memory stick:

 sudo dd if=Downloads/oracular-desktop-arm64+x1e.iso of=/dev/sdb bs=4M conv=sync status=progress

WARNING: Adapt the command before using it; if /dev/sdb is the wrong disk, you destroy your computer. Check e.g. with sudo fdisk --list for the right of= disk.

Install Grub and Linux (1st try)

Possibly you can go directly to my 2nd try...

• On windows, go to Einstellungen / System / Wiederherstellung
• Then click on Erweiterter Start / Jetzt neu starten (2x)
• Wait: The system reboots into BIOS Setup Utility
• Then: Run Problembehandlung / Erweiterte Optionen / UEFI Firmware Einstellungen / Neu Starten
• Then: UEFI Menu appears
• DO NOT RUN THE BOOTMANAGER (It will not run the installer)
• Instead, change the boot order under Setup

Install Grub and Linux (2nd try)

• On windows, go to Einstellungen / System / Wiederherstellung
• Then click on Erweiterter Start / Jetzt neu starten (2x)
• Wait: The system reboots into BIOS Setup Utility
• Then: Run Ein Gerät verwenden / USB ROM Drive
• Then the installer on USB drive boots. Select "Try or install Ubuntu"
• Do a manual install
  • allow to install 3rd party software
  • do not change the /boot disk-options, only set root and home partitions

Decrypt NTFS

I do not know if this is needed - but I did the following:

• On Windows, deactivate Bitlocker in "Einstellungen" / "Datenschutz und Sicherheit" / "Geräteverschlüsselung"
• This then takes a while
