How to Fix the Lenovo BIOS Update Failed Issue
If you get the Lenovo BIOS update stuck or failed issues, you can try the following methods to solve them.
Way 1. Install an OS
If no OS is installed on the Lenovo computer, the BIOS update may fail. When this occurs, the BIOS update process is skipped and moved to the normal boot process, or the BIOS version is the same as the version before the update. To avoid this issue, you need to install an OS first and then update the BIOS.
Way 2. Increase the EFI Partition
Nowadays, most modern computers will use the UEFI boot mode. Then, the computer will create an EFI/ESP (Extensible Firmware Interface) partition on the system disk.
This partition is a hidden FAT16/32 partition that contains the boot loaders, boot managers, device driver files for hardware devices present in a computer and used by the firmware at boot time, system utility programs that are intended to be run before an operating system is booted, and data files such as error logs.
When a computer is booted, the UEFI firmware will load files stored on the ESP to start operating systems and various utilities. In addition, the EFI partition can also be used to store and manage updates for UEFI firmware.
On the Lenovo computer, the EFI partition size may be around 100MB. You need to increase its size and the Lenovo BIOS update failed may be solved. To do that, you can try the following 2 methods.
#1. Use MiniTool Partition Wizard
This software can extend a FAT32 or NTFS partition for free. Here is the guide:
