Can't boot due to MBR error?
What is MBR?
A master boot record (MBR), or partition sector, is the 512-byte boot sector that is the first sector of a partitioned hard disk. The MBR may be used to hold a disk's primary partition table.
The MBR is not located in a partition; it is located at a Main Boot Record area in front of the first partition.I found a freeware way to recover the MBR if, while installing/uninstalling CTM something gets wrong and you can't boot due to MBR errors.
It's about
Partition Wizard Home Edition or, better, the
Partition Wizard Bootable CD.
You can rebuild the MBR:
Start Partition Wizard, select a physical disk (not an individual partition) listed in the main window, select from top menu Disk > Rebuild MBR.
If MBR (Master Boot Record) of disk is damaged, system cannot boot. This feature will rewrite the Master Boot Record of the selected disk without destroying the disk partition table.
Watch how to use Partition Wizard to Rebuild MBR in
this video.
Warning:
CTM will be unusable (can't run) after you restore the MBR.
All the snapshots are lost.
The system is booted in the "
baseline" of CTM and NOT in the "current state".
