[Trisquel-users] Re : help with dual boot install

[magicbanana]

You indeed need to define a partition that will host the root of Trisquel's  
hierarchy of files, i.e., /. I also advice you to have a separate file system  
to mount at /home, i.e., for the files of the users. The default install does  
it. In this way, something horrible can happen to the system and the user  
data are left untouched. I believe these file systems cannot be NTFS (even  
though NTFS partitions can be created). If the disk only has NTFS and FAT  
partitions, additional partitions need to be created to host a GNU/Linux  
system. If there is no free space on the disk some space can be made by  
reducing existing partitions (that of Windows in your case). You can simply  
rely on the option to install Trisquel aside Windows (although you can also  
opt for a custom partitioning as far as a partition is set to become the root  
of the file hierarchy).

I may have confused you. In the end the message is: "you can trust the  
installer when it proposes you to Trisquel alongside the existing operating  
systems; you do not need to mess up with custom partitioning".
