Error Installing XUBUNTU into Laptop MSI GE75 Raider 9SG - Installer does not recognice Internal HDs

What disk controller does the system use? Sounds like you need a driver for that.

If you try the OS and press CTRL + ALT + T you can run:

sudo lshw | less

You can read the hardware and see the RAID controller.

*-storage

Sorry for the last msg, it was sending for me by error.

The out put of the command show | less is too long for paste it hear. Thw only reference to RAID in the whole output are the following lines:

I hope this data can help.

That's perfect. If you run:

sudo apt install scsitools
sudo rescan-scsi-bus.sh

Do you then see the array with:

sudo fdisk -l

Thanks

Hi and many thanks for your help. I'm going to paste the result of rescan-scsi-tools:

It seems that it does not recognize any new disc:

0 new device(s) found.
0 device(s) removed.

This is the command and the result:

You could post on here, maybe. I can see the hardware certified. as far as I can see......

[Solved at 50%]

I have been able to solve the issue of installing ubuntu at the cost of exchanging RAID 0 configuration for a SATA AHCI system.

The MSI GE75 RAIDER MSG notebook has 2 SSD storage hard drives of 1 Terabyte each. When configuring them in the BIOS in RAID0 mode, the operating systems perceive a single disk of size 2 Terabytes.

A RAID 0 system is in intensive jobs is faster in write mode than the SATA AHCL system. This is why I consider the problem solved only at 50%.

However, I think we have been able to solve this by allocating disk 1 for reading the most of the time.

Into disk 1 lie the operating systems: windows, linux, etc ...

On disk 2 are all the data from Windows Documents, Windows images, videos etc, and the /home/users directories of linux.

Dedicating disk 1 to reading is easy with Linux, but somewhat more difficult in windows, where many applications only write to the disk where they are installed.

BIOS CONFIGURATION for installing linux ubuntu:

Start the bios by pressing the DELETE key before starting the device.
Delete the RAID system
Set SATA MODE SELECTION in AHCI mode

Now when we drag from USB we can see 2 hard drives and install ubuntu.

If you can think of any system to install ubuntu on raid 0 I will be happy to read it and even install it.

Thank you all for reading me and especially to actionparsnip. :)
