I installed Celena on a Dell C610 laptop this weekend. The laptop had a PCLinuxOS2007 distro on it when I decided to try Mint Celena.
I downloaded the iso and started up the LiveCD.
Most of the install was painless except for the partioner.
It took me over an hour of playing with the Mint partioner and also using command line fdisk before I could get it to stop telling me that it could not put the ext3 file system on my disk.
I was going for a total replacement, using the entire disk.
It finally worked and I am using it now to send this topic, but it sure was painful.
