Google Chrome OS was revealed. so I tried using it. Here is some notes to set up Chrome OS as virtual image in Windows. I downloaded the virtual image from gdgt website.
1.Go to http://gdgt.com and create your account.Email verification is required.
2.Download the virtual image of the Chrome OS from http://gdgt.com/google/chrome-os/download/
3. Download and install VMWare player.
4. Create a new virtual image in VMWare Player. I chose the Ubuntu as the OS. After finishing creating the virtual image, click the 'setting' to add the Chrome virtual disk. and delete the default hard disk image file. It's better to increase memory as 1GB or something. Then finish editing.
5. Click "Start player". and pale blue screen comes up. at the login screen. type your gmail account and password. At the time I got a problem. my login information is not recognized. Then I searched the web and found the solution. Right click at the network adapter icon on the right bottom of the VMWare Player and click "disconnect". Then again right click the network icon and click "connect". After that I could log in to the chrome.
6. The menu is really like The chrome browser, not operating system. There is no application menu nor OS menu. I don't know how to shut down the OS. just click the 'turn off' from VMWare menu? :(
7. After some research I found the way to access shell of the Chrome. Press the Ctrl + Alt + T displays shell. Typing recognition at the shell access was really slow and frequently dropped the characters. My PC's memory is 2GB and 800MB is used as Chrome OS. so I tried to run sshd to access remotely.
8. The default user at the shell is chronos and password is chronos. It took some time to figure out the default user's password. Then run /etc/init.d/ssh. Then I got an access from my terminal software. :)
fyi the Chorome OS is based on Ubuntu.

How to fix MBR problem
I have a lap top PC with Ubuntu 9.04 installed.
Today I tried to install Windows on my lap top to use as dual boot OS.
I followed the instruction written by here. When I boot with Windows XP CD and choose the partition to install Windows, I could not choose the free space. After that I reboot the laptop. then, Ubuntu couldn't boot up because Windows installation overwrote the MBR!
After the research to recover my MBR, I followed the instruction with this link and got around the issue.
http://ubuntuforums.org/showthread.php?t=224351
Windows sucks!!
To summarlize the solution, the commands I did are below.
1. Boot up with the Ubuntu live CD. In the terminal,
sudo grub
find /boot/grub/stage1
The output is like hd0,0
root (hd?,?)
# e.g. root (hd0,0)
setup (hd?)
# e.g. root (hd0)
quit
That's it!

How to fix the apt-get error on Ubuntu.
I got a following error when I tried to install something using apt-get.
'E:Encountered a section with no Package: header, Eroblem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_hardy-updates_multiverse_binary-i386_Packages, E:The package lists or status file could not be parsed or opened.'
I checked the web for the solution and found this command worked for me.
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

Office 2007 replaces Outlook Express dictionary English to French!
Today I was asked that my colleague have a problem with spell check in Outlook Express.
She told me that after I installed Microsoft Office 2007 to her PC, the spell checker got weird. I checked her PC and found that the dictionary of Outlook Express changed English to French. I researched the web and found the solution.
There is a fix program. You can access from here
