If i want to buy, then i think i will buy the vista version and install ubuntu as my alternative operating system. Because not all of my softwares can run above Ubuntu.

But i think i will use ubuntu as my primary operating system for internet. Since it’s safer? is it true that Linux is safer? ha ha ….LoL

First, login to your ubuntu. then:

1. execute sudo gedit /boot/menu.lst
2. The content will look like this
   …
   ## default num
   # Set the default entry to the entry number NUM. Numbering starts from 0, and
   # the entry number 0 is the default if the command is not used.
   #
   # You can specify ’saved’ instead of a number. In this case, the default entry
   # is the entry saved with the command ’savedefault’.
   # WARNING: If you are using dmraid do not use ’savedefault’ or your
   # array will desync and will not let you boot your system.
   default 0

3. You have to change the “default 0″ option to option for windows.
4. For example above, you should change “default 0″ to “default 5″ and the work is done.

Here’s the steps:

1. Install dpkg-dev by $ sudo apt-get install dpkg-dev.
2. plug in the usb flash disk and mount it to /media/disk (usually it’s automatically detected)
3. Ciot /var/cache/apt/archieves that have .deb extension to usb flash disk by executing cd ke /var/cache/apt/archives and then sudo cp *.deb /media/disk
4. Execute $ sudo dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

Now your usb flash disk can be used as repository source on synaptic.

I have installing it perfectly and everything is just works…But suddenly when i see my WiFi, it’s not working….. After some browsing, i found out that HP Pressario C767 is using Antheros just like Acer 4520. So i have to use ndiswrapper to diswrap the antheros driver for windows so the wifi will be recognized in Ubuntu.

To download the Antheros driver for Linux, click the download section from here. After you have downloaded it, extract to a place on your hard disk. Then use ndisgtk:

Click System > administration > windows wireless driver, browse for the .inf driver for atheros

After that, you may configure the Wifi by clicking system > administration > network settings.
