How to Install Windows 7 on a UEFI enabled Computer

We recently bought a Lenovo T-440s amd immediately loved it, except it came with a Windows 8 Professional, 64-bit. It had "downgrade rights" for Windows 7 Pro 64-bit. Unfortuantely, our corporate IT environment does not (yet) encourage Windows 8 especially in laptops nor desktops, so I really was obligated to downgrade it to Windows 7 Pro/Enterprise.

The T-440s is Windows 8 optimized and is UEFI and secure-boot enabled. As an IT professional, I am also interested in how UEFI works (later I'll write a blog after I successfully installed Kali Linux on dual-boot in a UEFI system) and if it indeed delivers to is promise. UEFI is explained in detail here. Microsoft also explains UEFI and how it is here.

Do note that UEFI systems behave differently depending on the model and brand of the computer. This how-to post is specifc to the T-440s. While the concept and the general procedures may be the same as with other laptops (i.e. Acer, Asus, HP, Dell, etc.) the behavior may differ slightly.

The Objective:  Install Windows 7 Professional 64-bit on a UEFI enabled Lenovo T-440s.

Before we begin, let us first discuss what are the differences between installing Windows OS in UEFI and in non-UEFI mode (aka Legacy Boot Mode)

1. UEFI installation of Windows 7 only works in 64-bit installations. 
2. UEFI does not work in Win XP. 
3. By default T-440s ships with Windows 8 and with UEFI and Secure Boot enabled. However Windows 7 normally is not for UEFI systems.  If your Lenovo Thinkpad T-440s ships with Windows 7, the settings may have been changed. 
4. The Lenovo Thinkpad T-440 does not have a CD/DVD Drive, you have to either attach a removable drive, or create a EFI-bootable Windows 7 USB Stick. 

Here's how:

1. Go to the BIOS Setup by rebooting your Lenovo Thinkpad T-440s then, repeatedly press F1 until you get to the BIOS Set-up Screen. 

How to Access Skype Chat History of Another Person or PC.

Internet messengers (IM) indeed made the world smaller, and skype is undoubtedly the major contributor to this phenomena. 

Skype is simple to use, and hard to block. With skype, you can do free calls and videoconferencing; share your desktop; and, share files such as documents and photos with any other skype users anywhere. Skype has the ability to use any available open port to communicate to the internet which made it a bane for traditional port-based firewalls to block (a headache for most network engineers).

But is skype safe? 

Paypal Spoof: How I knew the Paypal email I recieved was fraudulent

I had a recent experience with email spoofing involving Paypal, and I would like to share how I recognized the email as spoofed and thus was fraudulent.

My wife was selling her Macbook. Like most Gen X/Y couples do, we posted her for sale Macbook on eBay, and other trading sites. Two days later, we received an email from someone with a yahoo account asking what the prices would be in US dollars, including shipment to Nigeria. He didn't give a name and he didn't leave a shipping address. We told him the price would be US $450, but that he will have to shoulder the shipping cost depending on the address, and his favored shipping method/company would be. He said he wants to transact via Paypal, and even offered to up the price to US $580 including shipping cost -- what generosity.

So that night, I sent  him an invoice from my Paypal account. 24 hours past and I received a notification claiming to have come from services@intl.paypal.com informing me that payment had been made. Careful examination reveals it was a spoofed/phishing email. He was bamboozling me!  Here's how I immediately knew it was fake (click the picture to enlarge):
