Learn how to fix MBR on SSD to solve boot issues like invalid partition table, missing operating system, and so on.
MBR (Master Boot Record) is created while making the first partition on an SSD and is always located on the first sector. It’s the significant data structure containing the Partition Table for the SSD drive and a small amount of executable code for the boot start. Without a valid MBR, you cannot boot your system from an SSD. For example, when you migrate OS from HDD to SSD but find that the SSD is unbootable and displays error information as "operating system not found" "missing operating system" or "invalid partition table". In such a situation, you should consider that there may be something wrong with the MBR on SSD. To solve the problem, you should fix MBR on SSD on Windows 10/11.
