How to install grub after fatal error on failed RAID system?

by DBinJP   Last Updated November 15, 2017 06:02 AM

I know there are multiple posts about "Executing 'grub-install /dev/dm-3' failed. This is a fatal error", but in my case I have the additional problem of a corrupted RAID system (Windows 7 installation I'm trying to replace with Ubuntu 16.04.3) so I'm not sure how best to proceed.

Here is the RAID failure notice:

Intel(R) Rapid Storage Technology - Option ROM - 10.1.0.1008

Copyright(C) 2003-10 Intel Corporation. All Rights Reserved.

RAID Volumes:

ID Name Level Strip Size Status Bootable

0 Volume0 RAID0(Stripe) 128KB 477.0GB Failed No

Physical Devices Model Serial # Size Type/Status(Vol ID)

0 SAMSUNG [model and serial #] [all sizes 119.2GB 'Member Disk(0)']

1 SAMSUNG

3 SAMSUNG

I may be able to 'enter Configuration Utility' for the above RAID check screen, though this data was shared with me (I've not done this before) ...

What should I do, given the following output of fdisk -l? Given the two errors reported (invalid flag, Partition 2 not starting on physical boundary) I don't know what needs to be done.

ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/loop0: 1.4 GiB, 1532116992 bytes, 2992416 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
