Been trying to install Linux on a MSI Titan GT77, and every DVD distro I've tried so far (RHEL 7, CentOS 7, CentOS Stream 9) have all errored out immediately upon launch. Usually it would throw an error like "can't allocate initrd" followed by something like " Kernel Panic - Not syncing : VFS: unable to mount root fs on unknown-block (0,0) " (the unknown-block might be different, typing from memory).

I've turned off secure boot in the BIOS, but wasn't sure if there was some other setting in there I need to look for that would mess up the DVD from working.

(And the DVD does work, as I was able to create a VM from it. Just not sure if the VM approach will work for this project.)

Ideas? Thanks

would be nice to give us more details what did you exactly try, how....

Try a current Ubuntu server dvd. I get the feeling it could be a boot order choice for a legacy dvd and a uefi dvd issue.

RHEL 7 and CentOS 7 might not know how to use the i9-12900HX processor, which has P cores and E cores. One would think CentOS stream 9 should but I don't know which kernel it's using.

As mentioned in the previous post, Ubuntu, Debian, Fedora can run with these new processors.

Doh, I think pan64 posted correct info

Thanks for the help. Ubuntu out of the box didn't work, but it threw a different type of error ("out of memory") which got me to chase down the BIOS setting that messed everything up. In the advanced menu, there is a memory setting for Max TOLUD, and switching that from dynamic to 1.25Gb allowed Ubuntu as well as CentOS 7 to boot and start their installers.

We wrote off Ubuntu as a candidate OS based on the software we needed to run, so I was excluding Ubuntu-related results from my searches when I was google the heck out of this, but it ended up pointing me to the solution (TOLUD answer came from here: https://askubuntu.com/questions/1409...g-ubuntu-22-04)
