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

[o1e]

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

Still cant boot from both the Old and New iso. this whole process is frustrating.

had this issue with the latest iso. Solved this issue:

-- MotherBoard configuration
- ACPI off
- XHCI off
- Trusted Platform Security off
- CSM support Enabled
--- USB efi
--- Other Storage Legacy
- Secure Boot Off


---- At this stage system freezes with blinking cursor. But when I hit the Alt+F2 I saw login prompt via Console...

When I switched the Graphics from Asus to Internal Intel Graphics, I saw the login screen.

Hi all,

Have the exact same issue.

I have downloaded latest ISO and screen freezed with 100% .

ALT+F2 brings login prompt.

Hello @moty ,

Kindly check whether the ISO was burned onto USB properly/completely. If not, you could format the drive and burn it again.

NOTE: We recommend either Fedora Media writer or Command prompt to burn the drive

The latest Remote Exam ISO is not secure boot compliant and may not work on systems that have the Secure Boot setting "enabled".

You can try another system (if available) and see if it boots from the ISO otherwise you can try another version of ISO from this link which is secure boot compliant

Thank you all, for your advise.

It seems as an hardware comatibility issue, since I'm using laptop Dell G serias with AMD proccesor.

Finally, I switched to an older laptop and it works.

Thanks again.

I don't remember where I saw it, but it has been hinted that Ryzen CPUs don't play nicely with the Red Hat exam ISO. The official PDF does not mention any such problems -> https://www.redhat.com/rhdc/managed-files/tr-remote-exams-preparation-ebook-f27382-202103-en_2.pdf

Hi Guys,

So far my exam is rescheduled twice. I am having issue with external camera detection. After sharing the screen, only internal camera is detected. There is option at the top i think to select camera but on clicking it permission window flickers and doesn't allow me to select anything. For me the latest ISO doesn't work at all. Whenever I load latest ISO in memory after that my mouse keeps on flickering and doesn't allow me to select anything. So I used another ISO listes in this thread which brings me to compliance test but then I am unable to swithc camera. Any suggessions ? I don;t understand why the window keeps on flickering when I try to change webcam.

Thanks

Unfortunately, it really sounds like you're going to need to try a different setup. 

For me, I also needed a different webcam! I own a pricy Razer cam for streaming, which does not work with the exam setup. So I needed to spend €20 on a cheap Logitech, which worked perfectly.

First I couldn't create a bootable USB using Fedora Media Writer. Then I did it using dd method, on my Dell laptop it loads everything into memory and then drops a kernel panic message, something about VFS.

Is there still a valid older image that can be used for the exams?

[Tess]

There is, yes, it's been linked to in this thread multiple times. Look for "2020-08".

I used the older "2020-08" ISO last night, to pass my EX188.
