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

Hi,
There are issues with computer-tablet combos, like Microsoft Surface is. it is not likely the older ISO would be of any help, as it supports even smaller group of computers. I think the link to the odl ISO was depricated, but it can be provided to you individually by the support.
I woudl suggest you better get an ordinary mainstream office laptop for the exam.
