Install Windows 7 on x220

It took more than a month to get started with x220, and all the programming programs that have been released have been used. Actually, I want to know what kits I need, and

This is not required.

 

For example, the autolock and screen function of a person's notebook can be upgraded to 90 degrees at the beginning to improve the function of the notebook. However, it is really cool to use it.

In fact, the number of times is very small.

 

My oem OS version is Windows 7 Professional, So I went online and downloaded the ISO CD of Windows 7, and then refilled it.

 

Naively, the Order authentication should be in the bios and can be passed directly.

I deleted the magnetic region of the recovery at the beginning, but it was really difficult. I had to call customer service for help, but I didn't know it because I was a qualified us scheduler.

To restore the original CD.
So I had to go to Google to find a solution and remember to share it with people who have the same requirements as me.

 

1. Download Windows 7 ISO labels:

Because Windows 7 has a 30-day free license, the next license ISO License is legal.

1.0 I remember that I had to download some dynamic programs that were available or not available on the webpage. On x220, I couldn't use the network hardware on Windows.

There are other manual repair-free methods on the Internet, but I have not tried it. Save the token first and use it to protect the token. Otherwise, the website will not be connected after it is filled.

The parts to be renewed.

 

1.1 server guard Windows 7

I used a USB flash drive and used a Windows7-USB-DVD-tool.exe to make the ISO into a USB flash drive.

Then remember to log on to the USB server and remember to go to the BIOS to enable the first selection on the USB server so that the USB can be turned on.

 

 

2. lower limit LENOVO.XRM-MS

If Windows 7 has been reinstalled, it should be used for 30 days, but not yet used.

You can find the certificate of Lenovo OEM online.

The word "Lenovo. xrm-MS" or "201106/mobile01-e9d8ff8b6197c207c416b13cbeb22ac7.zip"

 

 

3. Import this OEM certificates

> Slmgr-ILC Lenovo. xrm-MS

 

 

4. Use slui.exe to verify the use of slui.exe

> Slui

 

In this case, you are requested to upload the product key. At first, I thought it was computer-> properties productid.

I have never been certified. My x220 product key is located near the battery pool,

some people on Google have sorted out the product keys of various OEM vendors. After the successful login, it should be similar to the loss.
