Hi,

I'm totally desperate. I try t install Ubuntu without success since two days. I read a lot of messages o forums, read instruction manuals... but I still have all my problems.

I have a PC (desktop) with windows 7 and I want to have a dual boot.
Configuration : Two hard drive, RAM : 8 Go, intel i7, 2.88 Ghz.

What I do :

Defragmentation of my hard drive C:. (hard drive array0)
Use of Easeus to make some place.
Download the latest release of ubuntu.
Use live linux usb to make a bootable usb.
Restart my computer.
Use the option "install linux alongside the others"
Go to the choice of time zone
Have an error with no text but interrogation markets (title : ??? message : ???)
Cannot continue, have to quit
Return to the menu : the choice "install alongside" has disappeared
choose "do somethings else"
leads to the same error at the same point

After this experience, I tried to use linux on live. Using the command sudo parted -l I get the following :


it@it:~$ sudo parted -l

Is your Windows
* encrypted?
* using RAID
* using disk spanning
Since you already have logical partitions, why not free some space, shrink the existing partitions, and create 2 more "plain logical" for Linux?

I'm unclear why there is any "drive mapper" - could you please run boot-info (links in my signature).
If you have enough RAM and fast enough CPU, could I recommend trying virtualization?
