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.
Please ensure that you are using the latest version of the RHRE ISO. I personally tested the new ISO and can confirm it works on the P50, P70, P71, P72, P73 laptops among others. There was an issue with one release of the exam ISO that had issues with the graphics card used by the Lenovo and some other laptop brands which has since been resolved fixing the "100% and black/blank screen problem".
Unfortunately, there is no new name for the link and the ISO is named the exact same, so if you are downloading from the PDF link for preparing for an exam and you already have an existing copy saved, it often will create a new copy and append a (1) or something else to the name of the ISO.
I believe the boot screen of the current version will say "RHRE.v20220719.F.46ea0c7" and the MD5 is 478157b7675223468d83253a241a1fd5.
I've 'HP Elitebook 745 g6. When I boot with "rhrexboot", it loads the image and counts goes till 100% after that screen blank and no activity shown. Also does not respond to any keys/combination.
After reading this post, I downloaded the "rhrexboot-2020-08, and used this image. Now the screen blanks just after booting.
I pressed Esc and I tried to select "check image and load exam... " & "load the exam..." but all having same effect. if I select "troubleshooting..." in troubleshooting page I selected to start with basic VGA driver..
Thanks & Regards
I am also having same problem with latest ISO with "rhrexboot" after 100%, I tried with "rhrexboot-2020-08" and it is working fine, however with "rhrexboot-2020-08" integrated camera feed show green and external webcam is working fine put problem with external webecam is, it is not able to read the photo id. Please help.
i had the same problem that my external WebCam was not able to read my id-card.
Luckily my internal WebCam was working, and i was allowed to use the internal Cam for identification.
I have the same issue with a Lenovo Thinkpad x270.
With the old 2020-08 version it is even worse, I just get a kernel panic. Can someone please help with this issue?
I have the same issue as described back April this year => "Cannot "Boot Remote Exam Live ISO USB for Remote Exam, Boot hanging at 100%."!
I have a ThinkPad T470 (a 4½ years old machine), and it works fine with the rhrexboot-2020-08.iso Image - but NOT with the rhrexboot.iso.
NOTE that: this machine also runs Red Hat Enterprise Linux release 8.4 (Ootpa) just fine, so it's not an unsupported machine in the Linux world.
I could, of course, try to go to my next exam using the rhrexboot-2020-08.iso, but as far as I understand the recommendation from Red Hat is to use rhrexboot.iso, and I don't want to have to reschedule in the last minute because of the ISO - so what to do?
Also, a small suggestion - pretty please:
Currently the "remote-exams-preparation-ebook" provides a direct link to the ISO, and when you click it (in a browser) the download of the approx. 2.5 GB typically starts right away/after a simple prompt! And, you have no easy way of knowing if this file is identical to the one you already have or it has been updated, i.e. before the download has completed and you have it on your local disk!
One suggestion could be that Red Hat instead, provides a link to a remote folder/directory, where you could see and select the latest/relevant ISO, and where you could see information on when it was uploaded/some release info, and additionally you could provide checksum(s) e.g. one or more of sha256sum, sha512sum and md5sum. (This is a common way to do these things, I guess.)
But other alternatives exist, so it's just one suggestion.
And, if you should wonder - then yes, I did try to access https://static.redhat.com/downloads/training-certification/ - but I got an "AccessDenied" response.
Please note that as I do not work for Red Hat this reply reflects my personal views only!
Anyway, I would suggest that you ask this question directly to "(Red Hat) Remote Exam readiness support".
You can find a link to this Support desk in the "getting ready for your Red Hat remote exam ebook"!
Note that the link I used to get to the ebook was this =>
When I recently (i.e 2021-12-08) contacted "(Red Hat) Remote Exam readiness support" I was told the following =>
["The older ISO (2020-08) can be currently used but it will be discontinued soon"
"If you are planning to appear for exam in upcoming week, the older ISO can be used ..."
"Once you schedule your exam or when you finalize the date of exam, you can contact us again and confirm it"
So, I assume that the answer would still be pretty much the same if you ask it today, assuming you have machine "somewhat similar to" the one I have etc. etc. - but I would suggest, that you ask the question directly to Red Hat Support, yourself.
I hope this reply was helpful!
I have a Lenovo t470s and the new ISO doesn't work for me. Does anybody have the MD5/SHA256 signature of the older image, rhrexboot-2020-08.iso ?
