Is BIOS and bootloader the same?
No, BIOS and bootloader are not the same. BIOS (Basic Input / Output System) is a program which is built into a system which enables it to know how to talk to other hardware devices. The BIOS runs every time the system starts up and carries out tasks such as configuring system hardware, detecting attached devices, and making sure all of the built-in components are functioning.
By contrast, a bootloader is a small program which looks for a certain file on a certain drive, and then instructs the operating system to start. Bootloaders are responsible for loading the operating system into memory and passing control over to the kernel.
They also enable users to choose which operating system they want to boot into. Therefore, BIOS and bootloader are not the same, although they are both necessary components of a computer system.
Can I unlock bootloader without OEM unlock?
No, you cannot unlock the bootloader of your device without using the OEM unlock option. OEM unlocking is a setting available in the Developer options in Android phones that needs to be enabled to unlock the device’s bootloader.

Additionally, OEM unlocking may void the warranty of your device, so it is important to be aware of any ramifications of using this option before you proceed.
Where bootloader is stored?
A bootloader is a type of program that is stored in a computer system’s non-volatile memory such as read-only memory (ROM). Its main job is to load the operating system or other programs into memory whenever the system is powered on or restarted.
In most modern computer systems, the bootloader is usually stored in the firmware, which is located in either an EEPROM or Flash memory chip. In some cases, the bootloader may reside in a special area of the hard drive, but this is only for specialized embedded computers.
The bootloader plays a very important role in the startup sequence of a computer system. It allows the user to select an operating system or other program to load, as well as make other settings such as the BIOS or other device drivers.
After the bootloader has initialized the system, it proceeds to the next step of loading the operating system. It is typically responsible for loading the kernel and the process manager, which then loads the rest of the system components.
The bootloader can also be used to manage the system’s hardware and software settings. This includes tasks such as enabling or disabling specific components, setting up the boot sequence, and other related tasks.
In some cases, the bootloader may also provide additional features, such as providing diagnostic information or providing a basic user interface.
Can you unlock your bootloader?
Yes, you can unlock the bootloader of your device. Unlocking the bootloader of your device varies depending on the device you use. If your device is from a major manufacturer such as Samsung, LG, HTC, Sony or Motorola, your device may have a unlockable bootloader by default, making the process much easier.
If it is not, you will have to work out how to unlock it by finding the necessary instructions.
Generally, unlocking the bootloader of your device requires you to enter fastboot mode on your device by connecting it to your computer and running a command such as “fastboot oem unlock” which will unlock the bootloader.
However, most devices have a more specific set of instructions, so it is best to check the manufacturer’s website for the exact steps.
After you have unlocked your device, you then need to be careful when you make changes in order to prevent bricking your device and make sure that you always use the latest firmware for the best compatibility.
How do I know which GRUB I have Windows 10?
