Lenovo G470 boot blue screen,insert boot disk and press any key appears after the blue screen only o

It is likely that the bootloader in the MBR or PBR has been corrupted after partitioning. In your **, I saw that your computer boot process is like this: first try to boot from the network card, the network card does not boot the computer, so it automatically exits, and then boots from the USB flash drive, and there is no operating system that can boot the computer in the USB flash drive, so the boot fails.

Prompt message"pxe"refers to the NIC boot, while"pen drive"It is a removable body memory, which is usually referred to as a USB flash drive. In this case, the BIOS must treat the USB flash drive and the hard disk as the same type of media, it may be that there is no hard disk or the USB flash drive set in the boot sequence is in front of the hard disk. Your description is that there was no problem with the hard disk partition before, that is, the bootloader of the hard disk was corrupted, and the BIOS could not find the bootloader on the hard disk.

The boot can be repaired with a mounting disk.

Lenovo G470 boot blue screen,Insert boot disk and press any key appear after blue screen is only occasionally like this about this problem,I think。

It would be nice if reinstalling the system would solve the problem, but, judging by your description, I think your hard drive is broken. The prompt that appears on the computer, no bootable device—insert boot disk and press any key This sentence means, there is no boot disk, please insert the boot disk, press any key to continue. It's just that your hard drive won't boot.

Because you said that your hard drive is ringing, it is really likely that it is a bad hard drive. If you think the desktop stuff is important, you can take it to the computer store and ask someone to get it for you, because it doesn't make much sense to talk too much here.

Dear users, hello!

This error occurs due to the failure to load due to the corruption or loss of the required registry hive file, which may be due to a corrupted hard disk or some other hardware issue. This can also happen if the driver corrupts the registry data when it is loaded into memory, or if the memory to which the registry is loaded has parity errors, in which case the external cache needs to be closed and the memory core needs to be checked.

If the hardware is completely fine.

Then it's a problem with the software, and these files that may be problematic are:

systemroot%\windows\system32\config\system

systemroot%\windows\system32\config\software

systemroot%\windows\system32\config\sam

systemroot%\windows\system32\config\security

systemroot%\system32\config\default

Boot with a disc or disassemble the hard drive to another machine, and replace the problem file with a file in the %systemroot%epair directory.

But if you have lattice the hard drive, and there is a problem again, then ......

The typical system boot device is set up incorrectly. If it's a system problem, it won't show the missing link of this sentence. Consider two points.

1.Turn on F1 and enter the BIOS to see if there is any error in the system boot device settings. If you are using a hard disk boot system, see if the first boot device is a hard diskIf not, turn it to a hard disk

2.If it has been set up to boot the hard disk, consider whether the boot file of the operating system is corrupted or missing. If this is the case, boot the computer and insert it into the system disk, and when there is a "System Repair Console", select this option.

3.The hard drive is in poor contact or damaged. (This is unlikely, but considerable.) ）
