Reading from windows a linux ext disk partition

Quite a few linux users have a disk partition with windows on it.
When using their linux OS whatever it may be, they simply enjoy accessing their data stored on their windows partition. But what about reading data stored on a linux ext2 / ext3 / ext4 partition from their windows OS?

There comes a big problem, when needing to read a file from the ext partition without wanting to restart their computer boot into the other OS and then reboot into windows to continiue their work?

It is a mess. I had this problem for a month or so but after googling for some hours I found out about the soloution.

There is a windows program that helps with this one.
Here is the link, to the free (till now) program http://www.diskinternals.com/linux-reader/ called Linux Reader.
It comes with some documentation but in any way you should not have any problem using it.

If you have any kind of problem, the comments are right below, and I am willing to help as soon as I can.

Toshiba Satellite Linux and Wireless

After running the Ubuntu successfully on my laptop, I realised that the wireless wasn't working.
I could connect to the internet through cable but it seemed that Ubuntu didn't found the wireless device.

It is simply a driver missing.
Luckily Realtek has drivers for its devices on its website.

These are the steps you need to follow:
  1. In terminal enter the command: lspci
  2. Search in the results for WiFi Adapter
  3. In the same line there will be the device id. (Mine was RTL8188CE)
  4. Go to the following site and in the search box search the device id you found in the previous step: http://www.realtek.com.tw/downloads/
  5. From the results you can download the driver for linux easily.
Further instructions are included in the file you download.


Toshiba Satellite Ubuntu

Well, I recently bought a Toshiba satellite laptop and I wanted of course to install Ubuntu to it.

If you are a linux user you will probably know that most linux distros use 2 partitions on the hard disk drive and they both need to be primary.

Coming to the windows 7 (Home Premium Edition which is preinstalled to the system) disk manager I was really unhappy to see that there were already 3 primary partitions on the disk.
Since these partitions are needed I thought it would be a good idea to try and install 5 primary partitions on the disk, as I had done some months earlier on my desktop computer and it had worked as expected.
Completing the installation of Ubuntu 10.04, after 2 or 3 restarts I only came to the login screen (of Ubuntu) with a not working keyboard.

Because the 3rd partition is used by windows for backup, I wasn't able to delete it as my system would not work properly.

What to do if you need Ubuntu on a Toshiba Satellite?

These are the steps you need to do to finally get Ubuntu 10.04 working on your laptop:

Here is how to backup the recovery partition and have it saved as a virtual drive:

Now go the disk management in windows (Right Click Computer->Manage->Disk Management) and delete the Data partition (the one you made the backup).

Here you may want to extend the windows partition to gain space usable on windows.
Then install Ubuntu using the largest continuous free space when asked where to install.

Now they should run properly.
For the wireless see the next post here.
