Dell G7 duel Ubuntu and Window failed

Question

Hi All,

I have a Dell G7 15 7590 with Windows 10 installed, and I would like to dual boot Ubuntu18.04 and Window10

I have carefully followed this community guide from here:

https://www.dell.com/support/article/us/en/19/sln301754/how-to-install-ubuntu-and-windows-8-or-10-as-a-dual-boot-on-your-dell-pc?lang=en

However, when I select 'Try Ubuntu without Install', it is giving me this error, showing me an "ACPI error no pointer back to namespace node in package", displayed just like below.

Error

Don't know if anyone can help me with this please.... I have been stuck with this for many days...

Many many thanks

You have to prepare the machine to install alongside windows.

Its not a one step water chicken install.

You have to use USB 2 optical Drive and 18.04.3 iso to boot from.

Burned media should be 1X 2X 4X max higher burning speed is not reliable. You are not able to LIVE BOOT with the USB media you currently have its crashing or corrupted or otherwise not working.

USB media introduces additional errors.

Its better to use a USB Blueray/DVD burner and boot from Burned Media.

The media is burned at 1X or 2X or 4X max.

UEFI BIOS Secure boot will also have issues.

The best method for dual boot is to do Windows first.

Shrink the Partition with Disk Management.
