View Full Version : [ubuntu] drive/partitions not shown

I give up---
Been trying for a couple of weeks to install Ubuntu - anything after 9.04. Here's my setup and problem.
System, quite old, is running Windows XP SP3 on a 250GB hdd and has 2GB ram. There's a second 250GB hdd that has 3 empty partitions on it that I've reserved for Ubuntu. I can install versions of Ubuntu up to, and including, 9.04 with no problem. When I trry to install any later version I can get to the step where I should be able to select the drive/partition but nothing is shown. Tried running from the live disk and using GParted and then installing but I still get the same thing - no drive or partition to install to. Have been searching for a solution online and tried just about all suggestions. Have tried finding something in Ubuntu Forums but gave up after a couple of days. Also tried many ways of mounting a partition from a terminal but I keep getting the same result - drive does not exist - . Anybody out ther have any suggestions?
Incidentally, have tried installing other Linux distros and have the same problem.
Will certainly appreciate any help.

Hm, it sounds like the disk has been used in raid and has meta data remains. In that case the installer is ignoring it thinking it must belong to a raid array.

Boot into live mode with the ubuntu cd, and in terminal try to remove the meta data. NOTE: do that only if the disk is NOT used in raid right now. If this second disk shows up as /dev/sdb in Gparted for example, the command to remove the meta data would be:
sudo dmraid -E -r /dev/sdb

If it asks you to confirm, do it and you should be fine installing after that.

darkod, you are indeed a lifesaver. Followed your instructions and in less than 5 minutes I was installing Ubuntu 12.04.
Thanks again==
