Hello,
I'm new here. I don't know if i give you enough informations.
After a failure during rebuild process on my RAID 1 system, i had to desabled RAID activity and i have now 2 independant disks.
The first one seems to be corrupted with many system errors. The second one contain my datas in a safe partition but when i boot on it i have an error /boot/efi is not ready or present ...i need to press S to get my session.
sdb with my datas :
sudo parted -s /dev/sdb unit s print

I would like to restore correctly my sdb disk before any other action. How can i do that safely. Can i copy sdb partitions on my sda disk even if i have lost my bootable partition and then reactivate RAID 1 ?
Thank you for your answers
