Lenovo laptop WIN8 system changed the General BIOS settings of WIN7, win8win7

Many of my friends have bought a new laptop with a Win8 system, but I found that this system is so hard to use and tangled. Let's change it to WIN7. This method can be used in the V, B, K, E, M series notebook: such as vrouters, V580, bda-, B580, B490, B590, K29, K49, E49, M490, and M495.

To change WIN8 to WIN7, we need to set BIOS: Change the BOOT Mode to legacy BOOT Mode.

1. when starting the system, Press F1, and some are FN and F2. (The two BIOS are shown in the figure. Let's look at the settings.) Then we enter the BIOS, choose restart> OS Optimized Defaults]

 

(Press [F2] to enter the BIOS. For some models, press [FN] + [F2] to enter the BIOS, select EXIT-OS Optimized ults and select win 8 64 BIT as Other OS ].)

2. Then we load the default BIOS settings on the keyboard [F9. Then, press [F10] to save and exit. (Whether the first BIOS is F9 and then press F10)

3. Then let's install the system. We may encounter the following problems:

1. Unable to partition or click Next After partitioning

2. It can be installed in a normal partition, but the windows logo crashes when windows is started.

3. A disk function error is prompted.

We must delete all the original partitions and then re-create the partitions. In this way, the installer will automatically change the hard disk from GPT to MBR, if you do not modify the partition, refer to my other articles for details about how to modify the partition of gpt mbr. Next, select the partitions, click Delete, delete all partitions, and then create and reinstall them.

If we still cannot install the system normally, we just need to ask for a Windows 7 drive or USB flash drive to go to the system installation interface.

On the installation page, press Shift + F10. In the Command Prompt window, enter diskpart press enter, select disk 0 press enter, clean press enter, and convert mbr press Enter; restart the computer and re-partition and install it. Do not make any mistakes in one step.

This is the same as when we installed the system. We will be able to use Windows 7 in just a dozen minutes. (To be honest, I really don't like WIN8)
