Dell XPS laptop cannot find hard drives

I have a Dell XPS laptop (Ubuntu 16.04) and recently tried to boot into it only to find I get dropped into a BusyBox shell with the prompt:
(initramfs)
It also says that it cannot find the root UUID in order to boot. So I tried to have a look in /dev/disks only to find it doesn't exist! I thought that there may be a hard drive problem so I ran the Dell diagnostic tool and that returns no errors. Also the BIOS can see the hard drive OK.
Next I ran a live usb of Ubuntu 18.04 and the file manager also cannot see the hard drives. I also checked
fdisk -l
lsblk
but they can't see the hard drive either. Checking dmesg | grep -i error I noticed that there were a few errors some relating to a PCIe bus error. I had a look online and found that there is a known bug (or was a known bug) relating to PCIe bus errors and the recommendation was to set the kernel parameter pci=noaer. However, this didn't work on the 16.04 installation.
I am totally stumped and was wondering if anyone had any suggestions?
Thanks in advance.
Update: Following the advice of Alvin Liang below, I went into the BIOS settings and changed the SATA operation from RAID On mode to AHCI and I was able to boot into the OS installation.

Could it be that your BIOS settings being reset so SATA is in RAID mode now? Can you change it to AHCI?

Thanks for your advice. That worked! I can't remember changing the BIOS settings or doing a reset but I must of at some point. Thanks again.
