How to change Legacy BIOS to UEFI on Windows

We often hear the terms BIOS and UEFI. But do you know how BIOS and UEFI work? Most computer users only know that if we turn on the computer, it will be preceded by a display of hardware information which is a report of the results of the BIOS/UEFI before the computer loads the operating system. Difference between BIOS and UEFI BIOS stands for Basic Input/Output System and is also known as system BIOS, ROM BIOS or PC BIOS. While the definition of BIOS is the firmware used to initialize the hardware during the boot process (power-on startup ), and to provide runtime services for the operating system and programs. The BIOS firmware is pre-installed on the computer's motherboard and is the first software that runs when the computer is turned on. The BIOS is stored in an EPROM (Erasable Programmable Read-Only Memory) which allows the manufacturer to perform updates easily. You can access the BIOS by pressing del, F2 or F10 during the initial phase of the boot procedure Unified Extensible Firmware Interface or what we usually call UEFI is the software between operating system and firmware. UEFI replaces the legacy Basic Input/Output System (BIOS) firmware interface that was originally on all computers with most UEFI firmware implementations providing support for legacy BIOS services. UEFI can support remote diagnostics and repair of computers, even without an operating system installed. BIOS and UEFI have the same task, namely initializing hardware components and starting the...

Change MBR to GPT without data loss using GDISK

Change MBR to GPT without data loss using GDISK

MBR (Master Boot Record) is a hard disk partition architecture whose job is to hold information about system files, logical partitions, and system settings. If we look at history, MBR has been around since 1983 issued by IBM along with the DOS operating system. Until now the DOS operating system is still running. GPT (GUID Partition Table) is the latest generation of hard drive partition technology replacing MBR. GPT is a technology that exists in UEFI bios next generation that is more sophisticated and complete. So a computer/laptop that uses a GPT partition must use UEFI. When we are going to move the hard disk from the old computer that still uses the MBR partition to the new computer using UEFI with GPT partition there is often a message By deleting all existing partitions, the problem will be resolved. But what if in the hard disk there is a lot of important data and we do not want to lose that data. To keep your data safe, follow these steps. Convert MBR to GPT steps Before you start installing windows, download GPT fdisk then extract and copy the file to flash disk.Do the installation process as usual. When it comes to the following steps (see image), there is a Windows message that cannot be installed. Press the Shift+F10 key to bring up the promt command. Then type "notepad", and on notepad click File > Open. Open the file on the flash disk (see rare 1), then select "gdisk64.exe/gdisk32.exe" and right-click. Next select Run as administrator. Then type the hard...
