I'm installing Lubuntu and I and dual-booting it with Windows 7. I want to be able to access all files while using either OS. My Hard drive has 4 partitions,

  1. sda1 200mb 'Windows 7 (Loader)',
  2. sda2 480gb 'Window 7 (Loader)',
  3. sda3 18gb 'Windows recovery' (or something close to that),
  4. sda4 100mb and no 'System' on it.

1,2 and 3 are all 'NTFS' (I think it was) and sda4 is FAT32. I don't know what FAT32 or NTFS mean, so can

1) Someone explain what FAT32/NTFS mean and do.

2) How I can make files on the biggest partition (sda2 480 GB 'Windows 7(Loader)'), available to both operating systems.

Bare in mind I am completely new to this area of computing and have next to no idea what I'm doing. Thank you :D

Have you either googled or looked at wikipedia to answer 1? I believe you will also find a lot of references to 2 on google as well. –  mdpc Apr 23 at 20:27

FAT32 and NTFS are both file systems. Each file system has its own way for storing and retrieving data.

Windows can use FAT (FAT*), exFAT and NTFS, where NTFS is the default.

Linux can use ext (ext*), ZFS, ReiserFS, btrfs and a lot more, including every file system Windows can use, where ext* is the default (usually ext3 or ext4).

So, if you want to be able to share data between Windows and Linux, you should choose a file system both operating systems can use. I suggest NTFS, as FAT and exFAT have their limits.

However, you cannot install Linux on a NTFS partition, so you should create a seperate system partition (ext*) to install Linux on.


You'll have to resize partitions in order to create a new partition (for Linux), because you're already using your whole disk for Windows (NTFS).

This may cause data corruption, so please make a backup of your important files before you do this, or make an image of your whole hard drive.

So I should make sda2 smaller and create a partition in ext4 to install Lubuntu on? (How big should this partition be?) –  Pyrozo Apr 23 at 21:09
    
Yeah, that's right. You can make the partition as big as you want. The minimal size is 5 GB (according to Ubuntu's wiki), but I would make it at least 20 GB to preserve some space for updates, programs you want to install, temp files and other stuff. –  Louis Matthijssen Apr 23 at 21:42

Wikipedia - In computing, a file system (or filesystem) is used to control how data is stored and retrieved. Without a file system, information placed in a storage area would be one large body of data with no way to tell where one piece of information stops and the next begins.

  • NTFS -> New Technology File System
  • FAT32 -> File Allocation Table

NTFS is newer File System by Microsoft and replacement to FAT32. One of the major drawback of FAT32 is that you cannot have a file of size greater than 4 GB.

Linux uses ext4 file system. Linux can only be installed on ext4 and Newer windows like 7,8 & Vista can be installed only on NTFS (maybe also on FAT32). You can access Windows NTFS & FAT32 partition from ubuntu but you cannot access ext4 from windows (Microsoft does not support ext4)

To access sda2 in Ubuntu open a terminal and enter following commands

sudo mkdir /mnt/sda2
sudo mount /dev/sda2 /mnt/sda2

then you can access+modify sda2 from /mnt/sda2

You need to make some partition smaller and my suggestion is that you make sda2 smaller and create a new partition of around 30-50 GB for Lubuntu from it –  Back.Slash Apr 23 at 21:11
    
I made sda2 smaller but now it says that the 10 gigabytes that it left unused are unusable? –  Pyrozo Apr 23 at 21:29
    
you can create a partition from unused space. Dont worry about file-system of partition you can always change file-system by formatting the new partition –  Back.Slash Apr 23 at 21:32
    
It doesn't give me an option to do that though –  Pyrozo Apr 23 at 21:33
