Hi All,
My aging CentOS 7 MicroServer is now out of support and not able to get any updates. I decided to perform a clean install of Rocky and use that as my OS moving forward. I downloaded the ISO, built a boot USB with dd and set about the task.
All looked fine, and I got the install screen up, tried to “Install Rocky” and it started the process, but shortly after it hangs and my HP MicroServer Gen 8 rebooted itself … and started the whole install over again. It seems to get to different points early on in the install and then just hangs and reboots over and over again. Sometimes I get the red bar at the bottom of the MicroServer flashing, but most times it just hangs and reboots.
Any ideas what the problem might be? I’m installing to a 750Gb SSD from a clean 64GB USB stick. The ISO was checked and seems fine with the checksums.
Cheers,
Ripface

system health issue ie power/fan maybe ? Can you try some other distro just a quick install - I assume you deleted the root partition already so nothing to lose…

Hi,
Ok, now I’m weirded out. Thought I’d try a different Distro as you helpfully suggested … so downloaded CentOS 9 and tried that. EXACTLY the same symptoms.
I’m installing to a virgin 750Gb Samsung SSD.
Flumoxed!!

While on CentOS 7, can you run ‘lspci -nn’ and show us the output?

@ripface Did you see my response? Is it the CPU not being supported?

Hi sspencerwire,
I suspect it may be CPU related. I’ll try booting from a live USB and check out the link you sent. Will let ya know how I get on.

Ok, tried to boot the Workstation Lite Live USB and it fails in exactly the same way as the install USB. Guess I’m on a hiding to nowhere. Someone asked for the lspci … output below in case that sheds any light on the problemo!

If you cannot follow the guide linked by @sspencerwire, you can try to check the output of the following command:
```bash
user@rocky:~$ cat /proc/cpuinfo | grep -o '\(cmpxchg16b\|lahf_lm\|popcnt\|sse3\|sse4_[1,2]\)'
```
If it finds the features within the `flags`, the cpu should be compatible.
You can refer to Wikpedia to see the list of features present in the specific `x86_64` versions.

You need at least `x86-64-v2` to install RL9.

Someone correct me if I am wrong, but it seems that your cpu is at least `x86-64-v2` and therefore should be compatible with RL9.

Hmmm, guess the issue lies elsewhere then. Never mind, I’ve ordered up a 2nd hand Gen 10 so we’ll see if that works with RL9. Talk about cracking a nut with a sledgehammer …

… maybe should have googled more before ordering the Gen 10. I had hoped to upgrade the CPU on it … but the damn thing appears to be soldered to the MB. WHY!!!

Could you show the

It reveals the device PCI IDs. Some of us can tell from the ID whether Rocky (or ELRepo) has a driver for that device. The installer can load additional drivers and hence cope with hardware that plain Rocky drivers won’t support (reliably or at all).

It seems from the cpuinfo output that the XEON is supported … but still getting issues installing. Thanks for the suggestion though!

Did you question your method of creating the bootable usb stick? Can you get any other distro to work?

The bootable USB was created using standard dd on my CentOS 7 box. It boots fine, but the install always fails as described. I have tried RL9 and CentOS 9 and both fail in exactly the same way. I have since built a new USB stick and it also exhibits the same symptoms.

I know it won’t solve your problem, but maybe you could try to live boot RL8 or Ubuntu just to check if the problem is exclusive to RHEL9.
