So on my recent upgrade to 10.10 Meerkat Ubuntu I decided to do a complete reinstall. Maybe I should of reconsidered…. I spent about 2 hours trying to figure out why my machine didn’t see any my partitions. It saw the drive /dev/sda but not the partitions. I wiped out the partitions with gparted, did it with ext4 format and completely empty, both didn’t work. Here is the basic info. Its an older machine, about 4 years I think? Its a simple server for the house. I have many, this one performs a few things.

Here is the specs

AMD 3200 64bit processor


1Gb of memory

Western Digital 80GB SATA drive

Promise SATA controller is in use instead of the VIA option.

Here is the answer to the problem. After searching the forums of Ubuntu, I found it. I want to thank user “Darkod” again for posting it. Basically you need to run two commands from terminal. If your in the install, hit the quit button on the installer. After that it will allow you to use Ubuntu to work like a LiveCD then. From there go to Programs > Accessories > Terminal.

Here are your commands:

sudo dmraid -E -r /dev/sda
sudo apt-get remove dmraid

After you run both commands, close the terminal, click on the Install Ubuntu icon and you should be able to install!

NOTE: After I wrote this I found that it removed my settings in the promise controller causing it not to boot. Simple solution, turn off the promise controller. Turn on the VIA controller and switch the cable around. Ubuntu installed flawlessly. Granted I don’t need a raid setup so this works for me, but it won’t work for everyone.
