Basically speaking, BIOS update refers to the update of the motherboard BIOS on a computer. Unlike other types of updates, the BIOS update will not bring us the system performance improvement.

Actually, you can recover data from hard disk without OS and bring the PC back to life when updated BIOS leads to a black screen. But how? Let’s just dive into this PC boot failure problem.
Issue: PC Not Booting after BIOS Update
Are you stuck with the computer not powering on problem after a BIOS update? manuntd7 said yes to this question.
Laptop Not Boot after BIOS UpdateSo I noticed that there was a BIOS update on my laptop and thought I'd update it. After flashing, the laptop was no longer booting in the OS and was simply launching the BIOS every time I turned it on. In the BIOS, when I select boot options, it states that there are no bootable devices but it detects my SSD. I tried reverting back to the old BIOS firmware but no luck. My laptop is an Asus F556UAK- manuntd7 posted in Tom’s Hardware Forum, waiting to get help.
The user manuntd7 described his personal experience in this post: he chose to update the BIOS after he had noticed the update push in the system. But after the work had been done, he discovered that his laptop won't boot after BIOS update.
In fact, PC won't boot after BIOS update has long been a hot topic on various forums. No matter you’d like to update BIOS in Windows 10 or other operating systems, PC not boot may become your worries.
Why the computer not booting after bios screen draws so much attention?
There are mainly two reasons:
Taking all these factors into account, I plan to share the practical recovery & repair solutions with you after the update of Windows BIOS failed.
Recovery: How to Access Data When BIOS Update Failed
In this part, I’ll tell you how to do the data recovery job when Windows 10 PC won't boot after BIOS update, from two aspects (if Windows 7 won't boot after BIOS update, the recovery solutions are roughly the same).
Recover Data from Unbootable Windows 10
Backup is important.
People often say that backup is very important, but very few of them really realize its importance. Only a small number of people form the habit of backing up useful data, let alone keep the backup updating from time to time. This is how you get yourself into the dilemma of data loss.
Data recovery from unbootable PC is possible.
Yet, the good news is PC data recovery is possible.
Which version to choose?
Can all versions help you recover all data from a PC this can't boot? Of course not! You should choose a version that contains the WinPE-Based Bootable Media (click to know more about the bootable disc). I suggest a Pro Ultimate license since it allows you to recover data.
Tip: You can also get MiniTool Power Data Recovery – the professional data recovery software for Windows 10 – to recover data.

Step 1: stop doing anything on the PC that refuses to boot.
Step 2: find another computer that works fine to build a MiniTool Boot Disk on a USB flash drive or CD/DVD disc.
Tip: Please see How to Build MiniTool Power Data Recovery Boot Disk talked about in part 2 of Operating System Not Found Error Appears, How To Recover Data.
Step 3: remove the boot disk you have made safely from another computer and then connect it properly to your PC that doesn’t boot.
Step 4: restart your computer and enter BIOS by pressing the corresponding button. After that, change the old boot order to make the boot disk the first boot device.
Step 5: exit BIOS and click to save changes.
Step 6: be ready to launch the software.
Step 7: afterward, you’ll see the MiniTool PE Loader window, in which you should choose the first option – Partition Wizard.
Step 8: choose Data Recovery from the following software interface.
Step 9: scan the disk.
Step 10: choose files to recover.
This is how to perform data recovery when the PC doesn’t boot up.
When you have found back all the files you need, you can do a data backup immediately for security reasons.
Repair: Computer Won’t Boot Windows 10
As for how to fix the computer startup problems in a Windows 10 system, I’ll give my suggestions in this part.
Method 1: Rebuild MBR

This is how to use MiniTool Partition Wizard to try to fix the problem when the computer won't boot up after a BIOS update.
Choice two: repair with Command Prompt.
Also, you can use other tools, like Command Prompt, to repair MBR (Master Boot Record) for your non-bootable computer.
Main steps are:
Method 2: Check & Fix Hard Drive
You can check and fix a hard drive by using the Command Prompt.
Method 3: Use Startup Repair
Two situations are involved in this method.
Situation one: you have the installation disc.
Situation two: you don’t have the installation disc.
Method 4: Roll Back to the Previous Build
The previous few steps are the same as those mentioned in method 3.
The difference lies in:
After selecting Troubleshoot and Advanced options in order, you should choose Go back to the previous build (instead of Startup Repair).
Method 5: Make Use of System Restore
Also, the previous few steps are the same as those mentioned in method 3.
The difference lies in:
After selecting Troubleshoot and Advanced options in order, you should click on System Restore in the Advanced options window.
Method 6: Uninstall the Windows Update
Method 7: Reset BIOS to Default
Method 8: Do a Clean Install or Custom Install
If all the above methods failed, you still have another choice which has always been useful – perform a clean install or a custom install.
The difference between them is that:
That’s all the mainstream solutions to fixing Windows 10 not booting after BIOS update.

There’re four main reasons to update BIOS:
What to Do before Updating Windows BIOS
Note: If the update fails in the real sense, the easiest and most direct way to recover is to contact your motherboard manufacturer or motherboard retailer to get a new BIOS chip. Then, replace the old BIOS chip with the new one by hiring experts or doing it under professional guidance. Besides, if the BIOS chip is attacked by virus, changing a new chip is a better fix than rewriting BIOS.
