Ubuntu installer does not show drives
- by Tanweer Rashid
I am trying to install Ubuntu 12.04 LTS on my Inspiron laptio, but the installer does not show any drives. My system has a 1TB SATA drive and a 32GB SSD. As far as I can figure, the boot files are kept on the SSD for fast startup (for Windows). During Win7 installation, I had to manually load drivers for RAID controller to see all available drives.
Running fdisk -l from the live CD shows the following:

ubuntu@ubuntu:~$
In the Ubuntu installer, I can only choose /dev/sdb for "Device for boot loader installation", and sdb doesn't show any drives.
I cannot select /dev/sda.
Any ideas anyone?
Thanks.
