Thinkpad T460s BIOS Update UEFI BIOS: 1.51 (N1CET83W) - Endless ReBooting

[mons_ipat2021]

Hi,

I recently updated the BIOS of my laptop in Lenovo Website.

Package: 1.5
UEFI BIOS: 1.51 (N1CET83W)
ECP: 1.14 (N1CHT32W)
BIOS Utility Window:n1cuj38w.exe

After running the update., the bios updated successfully shown after a reboot. However, once the laptop reboot to restart to Windows it no longer can find the boot device. The laptop just loops rebooting.

Access to BIOS is still possible.
Lenovo DIagnostic is shown when executing it cannot find it and just reboots in an endless loop.
Tried to reinstall Windows using USB boot, but it also does a reboot.

If you have any other advise, I would appreciate it.

thanks.

I updated mine to 1.53 with no issues. You may have to install it from a USB CD drive to get the latest version. You must burn the image it to the disc. When you start up you should see press enter ( press enter many times) to get to a boot screen than press enter again once in the boot screen to stop the count down. than press F12 to load USB media it will be under the HDD selection. If you do not see the press enter option restart and try again.
