CentOS

I just booted my Dell XPS 13 Plus 9320 - 12th gen i5-1240P (4 and 8 cores) and my lspci there is not showing those strange entries, just the normal ones of the format 01:00.0 or 00:1f.5. I have never seen PCI entries like yours before - they appear to have an extra 5 digit number prefixed at the sta...

You should report this on issues.redhat.com under RHEL then I think there is a version number "Stream 9" or something like that. No-one from RH reads this forum so no-one who either cares or can fix it will ever see these posts. There is only one driver for all SATA chipsets and that is the ahci mod...

Edit the kernel comand line at the grub menu and remove 'rhgb' and 'quiet' and then continue with the boot. It will not change the outcome but you should now be able to see any error messages issued that were previously invisible.

I do not understand why you want to use a nearly EOL distro like CentOS 7 for this. It's coming up for retirement and due to draw its pension and is looking forward to a nice life doing nothing. If you want to use a RHEL-alike o/s, use one of the newer rebuilds. CentOS is dead.

How about not using CentOS 7? It only has until June next year and then it dies anyway so you will be repeating the build in less than a year in order to stay secure. There are rebuilds of both RHEL 8 and 9 by Alma, Rocky and Oracle, all of which try to be as similar to the RHEL upstream as possible...

I'd also note that cpaznel supports both el8 and el9 though perhaps not Stream as that's a permanent beta. There are other rebuilds of RHEL 8 and 9 available since Red Hat killed CentOS. That doesn't help you with getting your data off but if you have ssh access then you should be able to copy from ...

I'm pretty sure that webtaqtic has been unmaintained for years so if you were using that for newer php etc, you're probably vulnerable to any security problems discovered since it died.

Sticking with CentOS 7 is not a long term solution. It only has 7 months of life left before it hits the end of the road so moving to a newer distro is definitely your best bet since you'll need to do it sooner or later anyway. Given that you appear not to have yum or dnf, there isn't going to be mu...

It's in the third party yum repo EPEL. Install epel-release then install pwgen.

Usual cause is a USB stick created withe.g rufus or some other utility that erases the hybrid UEFI/Legacy option from the copied iso file so it always boots in legacy mode even when the machine is in UEFI mode. The install then runs and installs in legacy mode.
