How To Download Official Windows 7 ISOs For Reinstallation

Some people find themselves unable to reinstall Windows 7 onto their machines, because they might have lost their Windows 7 backup images, backup external hard drives, and Windows 7 installation/recovery DVDs.  Of course, they can make a backup of their current working Windows 7 machines, but what if their current Windows 7 working machines are rigged with computer viruses and malware?  Another option is to go buy a brand new Windows 7 software in stores, but that is defeating the purpose of having a legitimate Windows 7 key in the first place (i.e., it came with the computer when you bought it).

Don’t sweat, I’ve found a website/blog post ( which lists available official Windows 7 ISOs for you to download and then burn them onto CD/DVD so you can reinstall Windows 7 onto your machines.  Obviously, you need valid Windows 7 keys to activate your Windows 7 installations, eventually.  Usually, there will be Windows 7 keys physically taped to your machines’ cases — look for the keys and you will find them somewhere on your machines’ cases.

For your information, I used VirusTotal’s “Submit a URL” scanner to scan for computer viruses and malware on these downloadable links of Windows 7 ISOs, and I’ve found nothing dangerous.  So, as far as I know from using VirusTotal, these downloadable links of Windows 7 ISOs seem to be safe and innocent.  Nonetheless, you may want to use your Linux machines’ ClamAV to scan for the downloads from these links for extra caution.  Good luck on your reinstallation of Windows 7!


How To Dual Boot Ubuntu 11.04 And Windows 7 The Traditional Way Through Grub 2

I’ve noticed some people may have troubles in doing dual boot for Ubuntu 11.04 and Windows 7, because sometimes Ubuntu 11.04 or Windows 7 just takes over as the only operating system that your machine can boot into.  Fortunately, I think you can solve this problem by following my little trick here!   I promise you will be able to dual boot your Windows 7 and Ubuntu 11.04.

  1. First, I suggest you to install Ubuntu 11.04 first, but before you can install Ubuntu, you need to use Ubuntu 11.04’s live CD to delete all partitions, format all partitions, designate custom partitions for Ubuntu 11.04 (e.g., /, /tmp, swap, /home).  Warning:  You will lose all data on your hard drives by following through this first step!  Do not complete this first step if you don’t want to do clean dual boot.
  2. Make sure you leave/create enough unused space for Windows 7 to install itself later.  That is, you should have around 80 GB of unused space for Windows 7 to create its own partitions later.  (I prefer 80 GB or more of hard drive space for Windows’ partitions, because Windows is rather large.).
  3. Installing Ubuntu 11.04
  4. Remove Ubuntu 11.04 CD/DVD
  5. Restart/reboot machine
  6. Pop Windows 7 CD/DVD into disk tray
  7. Install Windows 7 on the unused space
  8. Remove Windows 7 CD/DVD from disk tray
  9. Pop in Ubuntu 11.04 CD/DVD into disk tray
  10. Enter Ubuntu Live CD/DVD as “Trying out Ubuntu Live CD/DVD” so you can get to a terminal.
  11. Open a terminal
  12. Type in [sudo fdisk -l]
  13. Look for the device of your Ubuntu 11.04’s root installation (e.g., sdb1, sda1).  Hint:  Ubuntu’s devices should label with file system ext4 or ext3 or something that isn’t NTFS.
  14. Assuming Ubuntu 11.04 was installed on device sdb1, do this [sudo mount /dev/sdb1 /mnt]
  15. Now, do this [sudo grub-install –root-directory=/mnt /dev/sdb], notice there are two dashes in front of root-directory, and I’d not using sdb1 but sdb.
  16. Since the command in step 15 had reinstalled Grub 2, now we need to unmount the /mnt (i.e., sdb1) to clean up.  Do this [sudo umount /mnt]
  17. Reboot and remove Ubuntu 11.04 CD/DVD from disk tray.
  18. Log into Ubuntu 11.04 (you have no choice but it will make you log into Ubuntu 11.04 at this point).
  19. Open up a terminal in Ubuntu 11.04 (using real installation, not live CD/DVD).
  20. Execute this command [sudo update-grub].
  21. Reboot machine
  22. You should now see Grub 2 offers you ways to boot.  You can boot into Windows 7 or Ubuntu 11.04’s specific kernels.  Enjoy!

Only After Two Weeks Of Launching, Google+ Is On Track To Acquire More Than 10 Million Members

The social network world (i.e., social networking websites) certainly is getting weirder and more interesting as time progresses.  Remember Myspace?  Visiting Myspace today won’t be the same when it was hot!  Now, Facebook is so hot that we too feel the heat is too much to handle.  So, we think Facebook is it!  Nope, it seems Google+ might be the next too hot social network web service, and Facebook might have to go the way of Myspace.  Then again, nobody knows the future, but at least now we know Google+ has gained phenomenal traction — according to Techradar, only after two weeks of launching its social network Google+, Google sees Google+ gains almost 10 million members.  Don’t tell me that isn’t hot enough?


It’s Not So Wise For Netflix To Raise Prices By 60 Percent In A Down Economy

In a time when economy isn’t doing so well, services such as Netflix wants to raise prices would not win customers, I think.  It’s totally understandable for any business to tweak their service prices so bigger profit can be made, but doing it subtly might be wiser than doing it so boldly.  According to Yahoo’s finance news, Netflix raises DVD and streaming plan price by 60 percent.  In a good time, I think it’s totally doable, but in a bad economic time such as our, I think it’s a very bad decision for Netflix to push service prices 60 percent higher.

Netflix isn’t a bank where people absolutely need to borrow money to survive.  When people are feeling they need to cut back on spending most, Netflix is the easiest among all addictions to abstain from.  Also, Netflix is facing tough competitions such as Amazon and Redbox and Apple and Google and others…  I think customers will not hesitate to flock to cheaper services in a heartbeat.  Anyhow, what in this blog post are my opinions, and so you should not take them as facts.  Time will tell if I’m right about how people will react to Netflix’s raising service prices up to 60 percent or not.


Detecting Temperatures Of PC’s Components In Ubuntu 11.04

On Windows 7, you can use Core Temp software to monitor PC’s temperature (i.e., processors’ temperatures).  So, it’s cake just to get the software and fire up the executable program each time if you want to see the temperature of your PC using Core Temp on Windows 7.  How about on Ubuntu 11.04 (Linux)?

There are many ways, but as I Googled for ways, I found one which is very easy to do!  Assuming you know how to use Synaptic or apt-get or aptitude package manager, then this process is cake!  Follow the steps below (I give the source at the end of the post):

  1. Execute the command [sudo aptitude install lm-sensors]
  2. Execute the command [sensors-detect]
  3. Answer YES to questions you feel comfortable with.  Don’t worry, each question will accompany with short explanation which either prompts you to feel comfortable in answering yes or no.
  4. At the end of everything, it will tell you to enter one last command [sudo service module-inits-tools start], please do so just in case the necessary module isn’t yet loaded.
  5. Execute command [sensors] to display the temperatures of your PC’s various components inside the terminal, as you are/were.

As promised, here is the source:
