Hi,
I am fairly unfamiliar with all the concepts debated in this forum. Please apologise in advance if some
of the questions may seem naive.
My laptop boots from a raid 0 dual ssd in EFI mode.
The controller is an Intel SATA one (known as fakeRAID in the Linux world apparently).
I have recently managed to dual boot the computer with Windows 8,1 and Linux.
However after a crash of Linux (rare event), the computer does not boot any more.

I boot into a EFI Shell to try to see if I could repair the ESP. However, I cannot see the raid 0 disk.
That's what brings me to this forum. I believe the raid 0 still works (I manage to build the disk
itself with the raid although I cannot see the partition) but it might be corrupted.

I have two questions:
- is it possible that the raid 0 is still to be activated before the EFI shell boots,
in which case it would explain why I do not see it.
- if the previous is excluded, how can I check how corrupted the disk is ?

Thanks in advance.

Hi Fernando,

Thanks for your suggestion. The computer has a factory installed system.
I have created a backup and recovery (6 DVDs) but that suggests to
wipe the drive and re-install everything, which I am reluctant to go
given that I have spent hours installing both systems.
At any rate, I have tried a lot of solutions Parted Magic, Boot Repair and ALT Linux.
I believe the issue is beyond the reach of automatic fixes. I would like to
access the ESP and see if I can correct some entries manually.

Best

I'll try that. Thanks.
