    Dear All,

    we would like to install our new clearpass appliance with default OS version 6.7.0, to fresh installation clearpass 6.11.1

    we already follow guidance from Installing the ClearPass 6.11 ISO Image

    but after a while, we are getting error like this

    so we try to continue copy the iso file to mount flashdisk and continue process installation,

    but after that, we are getting notif screen like this,

    and after click on red hat, we got notif screen like this,

    anyone got an idea to solve this case ?

    Have you seen this video? It shows the required steps, including BIOS changes, for each of the different ClearPass hardware appliances.

    It looks like you did not change the system to EFI/UEFI boot.

    Hi Hudaya

    I got a similar error as you have in your first picture when installing 6.11.1 on a C3010 server a few weeks ago. In my case I had created the bootable USB stick from Windows 11 with Rufus. When a colleauge tried to create a new stick with dd on Linux it worked fine.

    I don't know if there was anyting wrong with my first stick, at least the SHA256 of the content of the stick matched the SHA256 of the files on the ISO.

    After verifying the UEFI settings mentioned by Herman, if the problem persists, it could be a worth a try to create a new USB stick.

    I had the same issue installing it on a C3010 appliance.

    After changing the BIOS to UEFI and enabling TPM2.0 I booted from the 6.11 ISO.
    On the first run I had the exact same error.

    Without futher troubleshooting I've just ran the installer a second time (reboot and start from the ISO again) and the installer finished without issues.

    When using Rufus on Windows there is a prompt asking if you want to write the USB stick in ISO or DD mode. Select DD and it will works
