Lenovo laptop has been in the progress bar after booting up

Check if there is a problem with the hard drive.

2. Select the last correct configuration, try the safe mode, if you can enter the safe mode, you can uninstall the recently installed software or driver. Repair system files.

3. If this is still the case, you can only redo the system.

Questioning management did not respond to any health.

Question: It's still the same to turn off and on again.

Stuck on the progress bar and not moving, I didn't respond to anything.

Question: I have a system USB flash drive.

How do you ask questions? Originally, you could do it yourself by pressing f12, but now the problem is that the button doesn't respond and can't get into the system to redo it.

It's less than a year to guess, and you're too naïve! As a technician, to give you a suggestion, the system under normal circumstances, about half a year to replace, from the phenomenon you expressed is estimated that the system problem is relatively large, it is recommended to change the system, thank you!

Turn on F8,Select the last correct configuration,Restart,No, try again,Try a few more times。

It's just that the system is broken, and the system should be redone in half a year.

1) Slow boot or stuck:

Don't operate it immediately after booting up, because the program is loading when you boot up, and you will try it in operation later, if it takes too long, look at the above method.

You disconnect the network cable and try to turn it on, if there is no problem, it is caused by slow boot networking, and it has nothing to do with the system (if it is a network problem, try to set a fixed IP).

If it is not caused by slow networking, first soft and then hard, such problems are caused by software conflicts, inappropriate drivers, and system problems, you can restore the system, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, don't install them if you find something that isn't suitable (if it's a hardware problem, please overhaul it, such as hard disk, etc.).

2) It may be that there is something wrong with the disk, please fix it (fix it for each disk or only fix C).

Built-in disk repair method:

The specific steps are as follows: select the drive letter in my computer, right-click to select the properties, select "Tools Start Checking" in the pop-up drive properties window, and select "Automatically repair file system errors" and "Scan and recover bad sectors", and then click Start, the scanning time will vary depending on the disk capacity and scanning options (after doing it according to the above method, a box will pop up, the point is, repair after automatic shutdown at boot, win7 select the disk check button according to the plan).

Bad sectors on the hard drive will lead to corruption or loss of computer system files, computer failure to boot or freeze. Hard disk bad sectors can be repaired using NDD Disk Utility or Scandisk.

If the fault persists, please restore the system or reinstall it (it is still not possible to format the hard disk and repartition and reinstall it, if it doesn't work, you will have to replace the hard disk, or overhaul it).

3) If this is always the case, first soft and then hard, reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, don't install anything that doesn't fit (if you have any questions, please ask me).

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

4) In terms of hardware, such as hard disk, memory, etc., whether there is a problem, whether the temperature of CPU and other hardware is high, if it is caused by hardware problems, it is recommended to overhaul it.

1.Check your hard drive for bad sectors!

2.Reinstall the system!

I don't feel like it, it seems that the hard disk has a bad sector, causing the system files to be lost or disordered.
