Cylinder 0, head 0 and sector 1 of hard disk are called MBR. MBR, namely Master Boot Record, comprises master boot program, disk partition table and valid partition flag. It doesn’t belong to any operating system. So, it can’t be read with the help of disk operating command provided by operating system. However, it can be modified and rewritten by command.
As we all know, once MBR is broken down, the computer system, such as system of Windows Server 2012 can’t be started. At the critical moment, successful MBR rebuild can help users start computer at once. When users meet the following several situations, this means they need to rebuild MBR in Windows Server 2012. Because of virus attack or incorrect operation, MBR is broken down. This makes hard drive can’t start. If this situation exists, system will prompt “Disk boot failure, Insert system disk and press Enter” after users open their computer. If the settings of hard disk in BIOS are correct (and hard disk can be found after starting from floppy disk or optical disk), then users can find out that start-up file of Windows or MBR of hard disk has been damaged. Sudden power off can also lead to damage of MBR.
In a word, if users encounter the above situations, they may need to rebuild MBR in Windows Server 2012 right away to normally start their computer.
When MBR is broken down, users had better rebuild it with the help of partition magic. Here we’d like to introduce MiniTool Partition Wizard to users to start their computer easily after MBR is damaged. And the steps are shown as follows:
1. To achieve rebuilding MBR in Windows Server 2012, users need to get MiniTool Partition Wizard Bootable CD first and burn it to USB flash disk, CD or DVD with Bootable Media Builder. To get the above interface, users need to put the bootable disk to CD driver and launch the computer after modifying the startup settings. Please choose the first option when the above picture comes out. Of course, users can choose the second in a particular case, such as choosing the first still with bootable failure.
2. Choose a display resolution to get the main interface of MiniTool Partition Wizard.
