Great, thank you, it works for me. It has MBR. Had some failed boots as some LVM monitoring service couldn't be started, but it works (still just legacy mode, doesn't work in UEFI).
I had to configure the Mic in the first screen where it allows me to setup the keyboard/etc...
I used new ISO for system checking. We are still facing issues with new ISO. OLD ISO image is working fine
Are there any special requirements for screen resolution for Preliminary exams?
