Error Installing CentOS 7 - An unknown error has occurred

[sardarjee]

I am having error installing CentOS on my PC. I get a popup with message "An unknown error has occured" with option to Report Bug or Quit.

PC Specs: AMD 2700X, 64 GB RAM and 1+2 TB NVME Storage (No Raid)

Tried installing from DVD and USB ISO in UEFI and non-UEFI mode.

Was able to successfully install Ubuntu though.

Thoughts what the issue might be?

The really interesting bit of the stacktrace is off the bottom of the screenshot you took but there's enough there to make me think that you have FakeRAID metadata on your existing disks and need to use e.g. dmraid -E -r /dev/sdX (amending sdX to the right device names). Boot the installer in rescue mode (an option off the troubleshooting menu when you first boot) and drop to a command prompt and try that then have another go.

Well, I tried using terminal (during install) and command failed with error message - no block device found.
dmraid -E -r /dev/nvme0
dmraid -E -r /dev/nvme0n1

I was able to list nvme device using lsblk command.

Just trying to understand what are other options to install CentOS. I installed on VirtualBox (on Ubuntu), using same ISO, and it worked great. But, VB is not the option that I am looking for.

Recreate the problem and this time scroll to the bottom of that error dialog box.

Do you have other disk drives in the machine other than the nvme one?
