Cannot Boot Remote Exam Live ISO USB for Remote Exam, Boot hanging at 100%

Jump to solution

Hello all,

i’m having some issues with the boot of the Remote Exam Live ISO.

During the preparation for the Remote Exam for ROL Course DO288, i tried to boot my Laptop using the Remote Exam Live ISO. I'm following the docs available here: https://www.redhat.com/en/resources/remote-exams-preparation-ebook.

Downloaded https://static.redhat.com/downloads/training-certification/rhrexboot.iso and written it to USB Stick by using the dd utility.

The boot process is starting until the screen "environment is loading into memory" appears, it counts up to 100% and then nothing more is happening. 

I tried different USB-Stick, always the same result.

For tests, i also used the rhrexboot-2020-08.iso Image, which i found as reference in an redhat Issue description, this one is working for me. Boot is without error, and the hardware compatibility checks are successful.

I plan to do the exam soon, thanks to advice how to proceed. I only have one Laptop available for the training/exam, it's a Lenovo Thinkpad P50.

Greetings

Oliver

A new exam ISO has been released for creating a USB boot disk that has most of the video drivers installed and fixed the issues I was having on a selection of Lenovo and other systems.

The new ISO is available and should have the following MD5Sum 

478157b7675223468d83253a241a1fd5

Hopefully this will address all issues with the Lenovo systems that haven't been working due to some video implementations and graphics cards.

Thanks to the exam team and @Curtis for working on this issue.

@Geoff@Jacqueline  and @Florian for information.
