[All] win8 is successfully killed in win7 -- a blood case caused by a small USB flash drive (the method for Windows 8 to be used for Windows 8) LenovoV580c

PS: In fact, I just bit my teeth and started the long-awaited MacBook Air, which is also the first PC that truly belongs to me. I thought: I can finally say goodbye to Windows.

But who once thought ...... A new colleague (Gender: female) has just bought Lenovo V580c, indicating that Apple's products will be spoiled at first glance )... And so on... Wipe... Nonsense... Pull back -- return to the subject.

In fact, MM asked me to help her replace win8 with the win7 system. I asked her for a USB flash drive and started the internal fight between win.

The battle begins ......

I. Download The win7 iso Image

Download link: find it by yourself. I was going to upload the local iso to the cloud, but it was too big to let it go...

Ii. Create a USB flash drive

Prepare a USB flash drive of 8 GB or above and download Chinese cabbage.

Use the cabbage tool to create a USB flash drive (this step is so easy, no nonsense)

3. Restart win8 and find the BIOS (important)

Nonsense:

I found that many of my colleagues got stuck here. During the restart, whether it was the delete, F2, F10, F8, or other keys, a crazy press, but it didn't work... The BIOS is not expected to appear. The damn win8 welcome page is displayed...

Solution:

1. Start win8 normally

2. Press the "win + I" key combination after the instance is fully powered on"

3. A list of options appears on the right side of the page (win8 has never been used, indicating that it is unknown)

4. Click "change computer settings" to go to the "computer settings" page.

5. On the "computer settings" page, click "general"> "Advanced Startup"> "restart"

6. After the restart, the system will go to the "select an option interface"

7. Select "Troubleshooting"> "advanced options"> "UEIF firmware Settings"

8. Start restarting and automatically enter the BIOS interface.

Iv. Enable USB flash drive

Nonsense:

Uefi bios supports two boot modes: Legacy BIOS Boot Mode and UEFI Boot Mode. Some devices and operating systems do not yet support UEFI-based BIOS, so you can only boot from Legacy BIOS Boot Mode. Depending on your situation, you may have to specify the uefi bios Boot Mode to use: Legacy BIOS boot mode or UEFI Boot Mode. Select the Legacy BIOS Boot Mode to allow hba and Express Module devices to use the ROM option. You can select UEFI Boot Mode to use the UEFI Driver.

Solution:

1. In the BIOS, select "Security"

2. Select "Secure Boot" under "Security" and change its status to "Disabled "(Note: This step directly affects whether Step 1 can be operated.)

3. Press ESC to return to the upper level and find "Startup"

4. Select UEFI/Legacy Boot under "Startup" and change its status to "Legacy Only"

5. also select Boot under "Startup", and then adjust "usb hdd" to the first place as prompted (the USB flash drive is preferentially started. If it still does not work, set all other USB headers to the Front)

6. Press F10 to save and exit restart (At this time, make sure that the USB flash drive has been inserted... Yes, insert...)

5. Deeply format the disk and modify the Partition Table type(Note: This step is dangerous. Please back up important documents (love action movies, etc.) first. If any mistakes are made, you will not be responsible for this)

Nonsense:

When you select to install a disk, the system will be prompted because the disk type is different: "The selected disk cannot be installed in the form of GPT partition ". In this case, you need to reset the partition format (Formatting cannot solve the problem)

Solution:

1. Press shift + F10 to enter the DOS command line.

2. Enter diskpart and press enter to operate partitions.

3. Enter select disk 0 and press enter -- select the disk to operate

4. Enter "clean" and press enter -- format the disk in depth.

5. Enter convert MBR and press enter to convert the disk to MBR partition form.

6. Exit DOS and refresh

6: so easy... No more... Listen to the voice of triumph!
