Lenovo x270--Genuine WIN10 replacement win7 BIOS configuration and system installation

The notebook installation system is now more and more difficult, the earliest universal Dafa legacy+ide+win7 pure version of the CD-ROM method has become more and more not adapt.

New company with a business trip notebook Lenovo X270, no longer have recordable optical drive, the impression of ThinkPad must have thinkvantage, this generation also useless, standard solid-state drive + mechanical hard disk can let the system boot speed reached 8 seconds, FN's combination of keys in WIN10 also use the smooth, The internal and external dual battery is equipped so that you do not shut down even if you unplug the removable battery.

Even so, the need to install a win 7 is required.

Share my installation process below.

My version of the X270 CPU is 6 generation i5, can install Win7, if unfortunately bought 7 generation i5, may not be so lucky to install.

First, change the configuration of the BIOS

Note: To enter the BIOS, the original WIN10 must be restarted in order to enter the optional prompt to enter the BIOS.

Forgive me for remembering to enter the BIOS del key, because different notebook brands are not the same.

Here is the configuration

Conventional Legacy+ide configuration in this generation ThinkPad X270 has no longer adapt, the latest BIOS are all AHCI way, the requirements of PE has improved, years reluctant to format the U disk update PE I, really difficult, so can find the best solution is Enter BIOS in security, close secure boot, in startup, change Uefi/legacy Boot to Both, and set Legacy to FIRST,CSM support set to Yes.

As follows

Enter security and close secure Boot

Press F10,save&exit after configuration is complete

After configuring the BIOS, the following is the process of Win7 installing the OS

Method One, try to use an external USB optical drive and burn a clean version of the Win7 image for installation.

Using the original Win7 installation, you will be prompted not to find the driver--failure;

install WIN7 Prompt "Missing required CD/DVD drive device Driver"

Method Two, Pe+ghost

Process:

1. The GE tool re-formats the original solid-state drive with WIN10 and 4K alignment.

2. Use PE to install Ghost's win7 image into the SSD-this process is smooth;

3. After the installation is complete, only through PE boot, local disk boot;

The image card is decrypted in the win7 window that is being started, unable to enter the system, starting to assume that it is being configured, resulting in 20 minutes without changes.

4. Attempt the system failed to boot successfully, try to use the PE repair boot-failure;

Finally no recruit, originally want to use USB CD-ROM to install, inadvertently saw the Windows 7 repair function, fluke, try to repair, unexpectedly-successfully repaired and entered the system.

Enter the system, but this ghost system does not recognize any of the X270 drivers, it is possible that this ghost image is not powerful enough to download.

To Lenovo Drive official website, download a good wireless card driver, install Lenovo driver Butler, matching driver installation end, a X270 pirated win 7 then installed successfully.

In the end, it is not recommended to install Win7, not because of a new system security upgrade for Windows systems.

First, because X270 comes with Win10 genuine and Office 365 genuine (requires Microsoft account for activation use);

Second, keyboard comes with FN combination of shortcut keys many in the win 7 system can not be compatible, measured only for sound and brightness adjustment;

Third, the starting speed is greatly discounted, the original Win10 basically 8-10 seconds to start, after installation Win7 can only guarantee the start between 20~29.
