Provide my spec and sorry for my poor English first.
- MB: Gigabyte G31M-S2L (bios ver. F9)
- CPU: intel E5200
- 2G RAM
- HD1: WD 160G with 2 partitions (partition 1:60G, NTFS, win xp; partition 2:100G, NTFS)
- HD2: WD 320G with 2 partitions (partition 3:220G, NTFS; partition 4:100G, ext4, Ubuntu)
Recently, I tried to install Ubuntu 12.04 Beta 2 on my desktop PC (on partition 4).
At the beginning, everything looked great including the auto-mounting of partitions 1~3 and the unity (3D).
However, after I deleted and re-allocated the partitions on HD2 and re-installed Ubuntu on partition 4, the partitions 1~3 are no longer auto-mounted when I logged in the desktop (and even the inserted cdrom would not be mounted either).
The configurations during these two installations are all the same as default.
Are there any possible reasons or solutions for this issue?
