Hi all! Does anyone know how I can change the SATA-mode from RAID to AHCI in the BIOS? I'm using a Predator Helios 300. I need to make these changes in order to access the SSD-disc when installing Ubuntu. I have tried going to the main tab and tapping Ctrl + s but no luck here. I'm grateful for any suggestions?

    @Powerknug92 it might perform a bit slower than SSD.

    @Powerknug92 do you see the Intel VMD option?

    @Powerknug92 okay. First, boot to the Windows, open msconfig and enable safe mode. Aftet that, go the BIOS, and disable VMD controller. When the laptop is booted to the safemode. Restart again and it should boots into normal state.

    @AnhEZ28 I followed the steps (I have also allocated disc space for both SSD and HDD) but when attempting to install Ubuntu it still does not detect the SSD-disc (only HDD). As seen in the print screen, there is only one slot of free space of 300 GB on the HDD appearing. There should be one for 30 GB as well. Any ideas?

    @Powerknug92 In the BIOS information tab, what does the SATA mode show?

    @AnhEZ28 It looks like this. Although now I had to revert /enable the VMD controller since I could not boot  Windows otherwise (perhaps because the Sata-mode changed and windows couldn't access the disc?). Is this any help or should I follow your steps again?

    @Powerknug92 before disabling the VMD controller make sure that the Safe boot is ticked in msconfig.

    after you have disabled VMD controller. Restart and it should into Windows safe mode. Restart the laptop again and it boots into normal Windows.

    @AnhEZ28 When I restart (after I have disabled VMD controller) I don't think windows can be loaded from the disc (see picture: No bootable device). So I cannot enter safe mode. Instead, I have to enable VMD again before being able to boot Windows. But when trying to boot Ubuntu instead, it still cannot find the free disc space for the SSD.

    @Powerknug92 I think I see problem. Your laptop is running on RAID because there are two same SSD. You might post the screenshot of disk management to see more further.

    @Powerknug92 boot to the Windows with VMD enabled. Try to open disk management to see if it is showing 2 or 3 drives.

    Here goes. For Disk 0 and Disk 1 I have 39.06 and 292.97 GB unallocated that I want to use. I Don't know what the partitions under volume are referring to though.

    @Powerknug92 I see. Definitely that yours is running on RAID-0 so you will have to either install ubuntu on the HDD or remove RAID (which requires backup everything and reinstall the Windows).

    Okay, I see. Do you think there will be significant performance issues booting Ubuntu on HDD? Since the SSD would only be used for boot and swap (perhaps not a problem since I have 32 GB RAM) maybe I won't see it as an issue. I will see if I can change from RAID to AHCI but does not look like it. Thanks for your insights, now I know how I want to move forward.
