    I flashed my bios but after the startup of my laptop the computer can not enter the operating system and stop work. and when I tried it flashed again I can't boot from the flash disk or CD because when I chose it to boot, the computer stoped again. My laptop is Lenovo G510

    Are you saying the laptop won't POST or has no power at all? Because that's going to present a very big problem. If you can post and enter the bios check your bios setup, your bios flash may have reset your sata mode to AHCI or ATA or something that would prevent booting to windows, or changed it from legacy to uefi.

    If there is no post you will need warranty service or to obtain and good bios chip from another g510 and solder.

    This is only semi related but I dislike seeing people go through this problem. If your computer is functional there is zero reason to upgrade to the newest bios. 99% of bios upgrades provide almost no benefit to the masses, the risk/reward of a bios flash is not worth it. So please avoid them at all cost especially when you are out of warranty, or it's your only laptop.

    Back in the old days I could recover from a bad bios flash with an old ISA video card or on some server or high end mobo there is a dual backup bios. On a consumer laptop I see no easy way to recover a bad bios flash (no POST). Good luck
