Bios Date 06/01/2021
Board Name: LNVNB161216
451AQN38L01 (4IMFG:2126)

Its not booting to windows, boot loop, live cd not working, its keep rebooting, linux as well, only EFI boot is allowed. tried different windows and linux distributions but its keep rebooting and tried to boot current windows, but on windows logo rebooting again.

I am unable to log to BIOS due to bios password.

post the 16MB bios, look for a bios chip on the board and post the content..

Attached is bios with password (lenovo_giga.rar and with password removed lenovo_giga (no password).rar). I was able to remove bios password, but laptop still no boot to the OS, its keep rebooting after windows logo and then tries recovery mode and reboots again, when I try to install windows from USB, it just reboots and loops again. So I logged in to the bios and enabled advanced mode by pressing Fn+R+N 3 times, changed some settings (I think it was hybrid or discrete graphic, something like that) and now I have just a black screen, power light is on and fans starting running. Not sure what to look now. Tried disconnecting battery and RTC battery, reflashing bios, still no fix.
Any suggestions?
