[Software] Boot issue

Hi everyone,

I need your help here.

I'm trying to solve a boot issue and I'm quite lost.
This morning I've restarted my Debian server because for applying a new kernel.

But the system refused to boot showing this error : "Error 1962 : no operating system found"
From what I've seen the error might be related to SATA cable or failing hard disk.

I have two disks in mirror and doubted the issue was the disks.
They are seen by the system, I can even mount them use a Live CD.

So I looked for a grub issue or a UEFI issue.
I've tried the debian live usb iso but it miss some tools like grub-install and I'm unsure how to use other tools :/

There were some hints it might be an issue with UEFI but until now it was working fine.
Nevertheless I changed the mode UEFI mode to Legacy.

That time the boot reached Grub but it ended in Grub rescue mode saying "error: disk 'mduuid/ba60d49b53e45326ba6fdb4c393e7420' not found"
At that point, it's beyond my competences and the search I've made on Google didn't help me.

My system is a Lenovo Thinkstation P500
My disks are two SSD disks in RAID
- sda: CT1000MX500SSD1
- sdb: CT1000MX500SSD1

I can try to give you more information if you wish and give me the commands I should run.

Many thanks for any insight.

EDIT: I've been able to install boot repair, here is the result of the diagnosis

EDIT2: I've tried to mount my Linux Raid partition to the Live CD but I fail for /dev/sda1 which is "EFI System" normally. But mount complains it's a linux raid member partition. However, I do not find any /dev/md corresponding to /dev/sda1 & sdb1
I cannot attempt an grub-install / update-grub :/
