Lenovo all in one reinstallation of Windows 7 cannot be performed

Solution: Reinstall win7.

CD Install Win7 Method:

Here's how to install win7

1.Put the burned win7 system disk into the optical drive where you need to reinstall the operating system and start the computer;

2.Press the DEL key to enter the BIOS to set the CD-ROM boot during the boot process, or press the F12 key to directly select the CD-ROM to boot during the boot process;

3.Windows 7 installation interface appears, first select Chinese (Simplified), Chinese (Simplified, China), Chinese (Simplified) - American keyboard, select and click Next, and then click "Install Now";

4.The installation agreement will appear during the startup of the installer, check the acceptance license terms;

5.Keep going until the partition interface appears, here select the first partition, type System, and then click Next (before this you can format the first partition, in the Drive option (Advanced) (a) there);

6.Wait for a while after the partition is completed, and then remind the installer that the service is being started, and then remind that the installation process will continue after restarting the computer, which is fully automatic;

7.After restarting again, take out the installation disc,It will automatically detect the hard disk boot into the system,Here there is a startup windows screen,The installer is checking the performance,Then see let the setting computer name enter the PC name here (take a name at will),Click Next,Password interface skip,Don't enter,Then the screen goes to enter the key,If it's genuine, then fill it in,If not,Don't fill it in,Use the activation tool later。

Hello, what system disc are you using, if it is a ghost system disc, this situation may occur, it is recommended that you use a normal operating system.

If your computer comes with an operating system, you can contact your local service station for a factory reset.

Lenovo Service Station Inquiry:

You need to reset the hard disk to boot. Step 1: Press the F12 button to enter the BIOS when the computer is turned on; Step 2:

In the BIOS boot menu, change Secure Boot to Disabled; Step 3: Change the boot list option to legacy, restart; Step 4: Press F2 to enter the BIOS interface again, select the "Advanced BIOS Features" setting item, and press the Enter key to enter. Step 5:

Select the first item (boot from hard disk); Step 6: Press F10, then select "Y", click "Enter" to complete the setup, and restart the computer.

3. Take out the motherboard battery and discharge it, which is caused by disk damage.

Question: If it can't be started, how can I restore it in safe mode?

1. Turn on the computer, if you are running Windows, please restart the computer;

2. When the computer is turned on, please pay attention to the screen when it appears"starting

windows

95", press and hold the F5 key so that you can enter safe mode;

3. Or, when the computer is turned on, when it appears"starting

windows

95", quickly press and hold the F8 key and select the third item in the startup menu that appears"safe

mode"。

The question is that it can't be turned on, and it can't be displayed at all, let alone run.

First, remove the graphics card, hard disk, optical drive, and network card.

1. Only the CPU, cooling fan, and memory are left, and if they are not restarted after booting, it means that there is no problem with the above components and power supply, and the second item can be carried out;

2. If it is restarted, it means that there is a problem with the motherboard or power supply;

A. Motherboard: Carefully check the 3300UF capacitor next to the CPU on the motherboard to see if there is any "bulging" and "leakage" phenomenon.

b. Power supply: If the cooling fan of the power supply appears: poor operation, increased resistance, and deformation of the blades, resulting in smaller wind power, resulting in poor heat dissipation, it will directly affect the divergence of the dissipated power of the power supply, and the power factor will be reduced, which will not meet the needs of the whole machine, and force the host to restart for self-protection;

If the filter capacitor of the power supply (generally a high-voltage capacitor, 220UF 200V) has serious leakage and soft breakdown, the power dissipation will also be reduced;

2. Install the graphics card and connect the monitor.

1. If there is a display and does not restart, the third item will be carried out;

2. If it is restarted, it is said that there is a partial short-circuit fault in the card, which is generally due to the excessive leakage current and soft breakdown fault of the UF 16V capacitor, which can be replaced;

3. Install the hard disk, optical drive, and network card respectively.

If it continues to restart, it means that the optical drive and network card have a short-circuit fault, which is generally caused by capacitors;

Or if there is a problem with the system, you can reinstall the system.
