No disc detected during installation
No disc detected during installation
I have a small HP Proliant Microserver used in our small office.
Several months ago I had installed minimal mode of Fedora 30 Server for testing and there is no data file in the server.
I'd like to move to CentOS 8.
During installation, I need CentOS to wipe out Fedora 30.
But no disc detected during installation.
Please see the attached photos.
And what should be done next ?

Re: No disc detected during installation
You are most likely suffering from the issues discussed in this thread (kernel missing driver needed for your hardware):

Re: No disc detected during installation
I have installed CentOS 7 instead.
CentOS 7 solved this problem.

Re: No disc detected during installation
7 had some driver your system needs, 8 does not, and so the latter won't install on some systems which were fine with the previous version.
It is more than a little annoying that the installer only offers up " no disk found" when it should at least process lspci to see what it is working with and note that there is no driver for some storage controller. What happened to you happened to many of us, and many of us were baffled why a system that worked at 7 did not work at 8. CentOS Plus would fix most of these, but that product does not have an installer with a kernel which includes the missing drivers, so getting there will be a battle.
Re: No disc detected during installation
Many of the missing drivers are packaged by ELRepo and can be used as Driver Update Disks at install time. You'd have to post the output from lspci -nn for anyone to be able to identify the exact model of controller and to check what is used for it.
CentOS 6 died in November 2020 - migrate to a new version!

Re: No disc detected during installation
Exactly - the fix is a bunch of unexpected extra steps which fall into the end user's lap at a time when the computer is basically unusable. It is possible that the network driver might also be missing, but I have yet to see anybody encounter that, so rather than:
Code: Select all
no disk found
Code: Select all
no disk found
network available? yes
check El Repo for missing drivers (Y/n)?
Y
connecting to El Repo
checking for missing drivers for this hardware
Found missing driver(s):
WHATEVER storage control driver
Install missing drivers (Y/n)?
Y
Installing...
Scanning for disks...
Disk found
Either that or come up with a CentOS Plus installer with a CentOS Plus kernel, which would likely fix most of these "no disk found" problems.
