CentOS - Mar 2019 - Centos installer not detecting hard drive

Hi,

I have a new labtop and i want to install CentOS 7.6 on it.
My labtop has two hard drives :
- A 256Go SSD
- A standard 1 To hard drive
None of the two hard drives are detected by the Centos installer
consequently i can't proceed with the installation.

If i try with a Fedora server distro, then the standard hard drive is
detected, the SSD one is still not detected.

I do prefer to install Centos as is is the closed Linux version from RHEL,
so what can i do to solve the issue ?

Regards,

Faird

This may be a remote possibility because it happened to me long ago but, were
these disks used for something else previously?  I had a situation where
something "special" a program did on the disk caused Linux to not
recognize the drive.  In that case I was able to use the manufacturer's
"restore the drive to its original condition" program to remove the
problem.  I've also seen other situations where using dd to write zeros to
the first 10K or so of the drive got around problems (if the drive is even
recognized...).  If this is your situation and the manufacturer doesn't
offer a "restore..." program you might try other distros'
"leading edge" Live CDs to hopefully detect the drive and do something
with it then install CentOS.

Some notebooks need a change in the BIOS - the section where the disk
controller is set to either AHCI or RAID or <something else>.
Linux needs the controller in AHCI mode.
If you set it from RAID to AHCI, then your Windows (if you plan to
dual-boot) might not start anymore because its drivers expect the
controller in RAID mode. This can typically be fixed - google for it.
