I installed Windows 7 and Windows 8 in on a hard disk some days ago. Today, the bootloader got missing/corrupted. I currently have the Windows 8 installer on a flash drive and tried using the Automatic Repair option to repair the bootloader but it didn't do anything. The Startup Repair option is also missing in the Windows 8 installer. How I can repair my computer?
- Question from Super User
The bootloader is a program that loads the operating system (such as Windows 8, 10, or 11) during startup. And an EFI file is a type of file used by the Unified Extensible Firmware Interface (UEFI). These files are part of the boot process and tell the computer how to start up. If the UEFI bootloader is damaged or missing, the system won’t be able to boot. In such cases, you need to repair the UEFI bootloader.
