I started installing PCLOS 2010.10 Gnome in my 500gb hard drive along side Vista.
There were 3 partitions in use on the disc named, Vista, Files and Extra space as well as 128GB of unformatted free space.
I hit the install button, chose use free space and hit next. The installer then said something like operation complete and said re-start installer to complete installation, then disapeared when I clicked OK.
I attempted to re-start the installer. I got the login screen for root password, entered the password and the installer sort of flashed something on the screen that looked like its border, then crashed. Simply disappeared. I tried starting the installer again with the same result.
I attempted a switch user but the thing wouldn't let me log in as root so I could have a look at GParted, so I logged out and re-booted.
Upon re-boot I logged on as root and looked at Gparted to find my whole disc is now un-allocated space.
