Boot with live DVD again. Open a terminal Window (Menu > Terminal), run this command and post the output.

Code: Select all

sudo fdisk -l

fdisk is showing that Linux does indeed see your three Windows partitions (1 hidden recovery partition).

Could you, from the Live DVD, run the application GParted? Please take a screenshot of that and share it here. If these three partitions are seen in GParted, we can guide your through doing the partitioning for Linux with GParted. After that is done, hopefully in the installer these partitions will then be selectable for installation.

howdy m8 from the screenshot you posted, i don't think there's any windozed installed probably that's why it goes straight to installation..

but just to make sure, can you run live CD then open the terminal and type "sudo os-prober" ... let us know what are the results.

Try installing Mint 11 or Mint 9 and see if the problem is the same :?

Pretty sure it is caused by the crappy Acer recovery partition (PQSERVICE) plus their custom MBR... You could fix it e.g. via EasyBCD or by booting to WinRE and running

Code: Select all

Bootrec.exe /FixMbr
from there.

Note that the system restore/recovery feature (usually accessible via something like Alt+F10 on boot) will become unusable!!!
