Hi Guys,

I am very new to linux and hope that you guys will be able to help me out.

I have TWO 1TB drives configured as RAID 1 using the PROMISE RAID BIOs setup.
POP in the installation disc and started the installation, using the 'Guided' partition method.
Towards the end of installation for the Ubuntu Server 14.04.3 LTS, it prompts me that 'GRUB was unable to install'.
I continued with the installation till it prompts for a restart.

Upon restart, the ubuntu server will not load.
i booted the system using the Ubuntu Desktop disk and below is the fdisk:


ubuntu@ubuntu:~$ sudo fdisk -l
