Red Hat Exam Environment Not Booting

Jump to solution

Hi,

I tried to boot the Red Hat Remote Exam ISO, to run the compatibility test, but when it gets to the part where it shows the Red Hat logo, the system says that it is at 100% and after like 5 second it displays the following error: "error: ../../grub-core/lib/relocator.c:1439:out of memory." and after a few seconds the screen goes blank and then displays a Kernel panic message: "VFS: Unable to mount root fs on unknown-block(0,0)".

The steps I took to boot the exam environment:

1) wrote the ISO to the USB device on Windows 10 with the Fedora Media Writer

2) tried to boot the exam environment, but it failed

3) re-wrote the USB device on the Windows 10 environment, because I thought something might have happened during the first write

4) tried to boot again, the boot process fails again with the same error

5) re-wrote the USB device, now on a Linux environment, with the "dd" utility

6) tried to boot again the exam environment, fails again, with the same message

The USB device that I`m using is a SanDisk 64GB device; the image, which I`m using, is the rhrexboot-2023-06.iso.

My machine is an older Lenovo Legion 7 gaming laptop with an Intel CPU, 16GB RAM.

In the email that I received from Red Hat it was stated that I need to have a minimum of 8GB RAM, my system has 16GB so I do not understand why does it say that it is out of memory.

Has anybody run into this problem? Does this ISO require more than 16GB RAM?

 

Thanks in advance for your help.

speakers are not needed, so if you plug in an usb headset, leave it on the desk and use it just as a microphone, you shoudl be fine also with sound. Redhat needs to hear the sound in your room, speakers are not needed as the chat with RH is only written
