What to do if the laptop does not start after updating the drivers?

Question

Iron

People need help, laptop lenovo thinkpad e555, 2 video cards R7 and R5. Today, the drivers offered to update themselves and I fell for it like a fool. After updating and rebooting, 3-5 seconds after the desktop appeared, a message appeared stating that the video driver was restored and immediately everything hung and after 10 seconds it fell into a black screen.
Everything would be fine, but now immediately after the initialization of the BIOS (passes without visible errors), a black screen immediately ... Even bootable flash drives with various software do not start (or it is not visible that they started), immediately a black screen. At the same time in the BIOS everything works fine.
Actually who faced? what to do and how to treat?
ADDED:
A colleague on the exact same laptop has the same issue after an update! Tin.
Added:
I managed to connect to the laptop via remote desktop, in the properties of network cards on the events tab, every time the computer boots up, there are the following entries: about adding driver components (all with code 0x00) then about turning off the adapter and removing it (still with code 0x00)

Answer 1

reset bios not default and boot from liv-sd.

Answer 2

Hello. It may help: when you turn on the laptop, press F8 without stopping until a menu appears (in which you can still select safe mode, etc.). Select "Load Last Known Good Configuration". It helped with the installation of mowing firewood and the daemon tools of the wrong bitness.

Answer 3

Try to boot from some ERD-commander

Answer 4

Alternatively, try updating your BIOS. Surely in the BIOS itself there is a utility for updating via a flash drive or directly via the Internet (the laptop seems to be modern).

Answer 5

Lenovo has a recovery button. If you didn’t kill the corresponding section of the railway, then everything should work out.
