Knowing reasons for operating system boot failure is important for users to solve this problem. So, in this essay, we will tell users some reasons for this kind of failure first. There will be two common reasons introduced in the following content.
1. Not Find HAL.DLL File and Start Stops
Wrong Configuration of Boot.ini File
This operating system boot failure is caused due to the mistaken configuration of boot.ini file. When Windows starts, it can’t find the path of HAL.DLL file. This finally causes computer black screen.
Trojan Virus Attacks Computer
Because Trojan virus destroys computer boot process, HAL.DLL file is damaged or deleted. Computer won’t start if this boot file is broken down.
2. Computer Won’t Start Due to Damaged Master Boot Record
MBR doesn’t belong to any operating system and can’t be read with disk operating command provided by operating system. However, it is a computer boot process which can be easily attacked by virus. If MBR code segment is damaged because of virus attack or improper partition operation, operating system boot failure may appear.
If operating system boot failure appears because of MBR problem, users can choose to rebuild MBR to solve the problem. Then, how to realize rebuilding MBR with ease? Certainly, MiniTool Partition Wizard is a good choice for users to achieve this.
Step 1: To rebuild MBR by using this powerful software, users need to get MiniTool Partition Wizard Bootable CD first. And then they should burn it to USB flash drive (or CD/DVD). Next, users should insert this USB flash drive to computer and start computer to get the following interface.
Step 2: Choose the first boot mode from the above screenshot and press “Enter” (users can also choose to boot computer from the second safe mode if there is a special need).
Step 3: The first display resolution is chosen by default. If it is not suitable for users’ computer, they can choose another one.
Step 4: Click “Rebuild MBR” after choosing system disk in main interface of this software.
Step 5: Click “Apply” in the main interface.
Users can solve operating system boot failure easily after they know the reasons for this failure and solutions to it. If users’ computer won’t start, they can try to rebuild MBR with this partition magic.
