How to recover RAID0 files with Boot Os on?

[mike61986]

Greetings to all..,

I would like some advice for my problem below.

Long story short:
I have an MSI GS70 Notebook with 2xSSD's in RAID0 with boot OS on them and an extra HDD. I went through a BIOS update and it messed up my RAID0. As a result only one disk was shown as RAID0 and the other Non-RAID.

I followed instructions on how to re-build the RAID0 (exactly as it was)and I have booted up through a USB Win on The GO. I am on a stage where I see the disk but I have four partitions (see attached)
Which of the four should I choose? The one with the actual size of the disk (bigger in size)? The others are the system reserved memory partitions.

Any advice on what my next steps should be?

The hole thing is to try and save some Data that I did not backed up (Geotechnical Numerical Analyses) and it will take around 10 days to re-do them...I am mainly interested in saving the files and if possible restore the whole system.
I have not initialized or formatted the disks, I have only followed the procedure to re-create the RAID0 with the 2xSSD's

Looking forward for any advice.

Kind regards,
Michael

Using the arrow keys, set all partitions as P(rimary). One of them should be set as *(bootable), it's probably the first one.
On next screen, choose Write, confirm, Quit and restart your computer.Check that you can access the files.
