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.
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”.
I’ve tested in a XP Virtualbox machine and it worked like a charm. Seems that it could help users with install/uninstall troubles with CTM.
Of course it does not solve all the problems. If you have a driver corruption (and can’t boot with “Last known good” configuration), you still have a BSOD loop and the Partition Wizard won’t help.
That’s why I recommended Paragopn Hard Disk Manager about a month aog. It can do an MBR rebuild without affecting the disk partition layout. The SE version is available on several magazine coverdisks.

I have with “TestDisk” wrote the New Mbr. After that I started with the boot Console CTM and restore a snapshot can be. That worked. Obviously you can let write the MBR is still new and the CTM installation are all snapshots.

ok, i do the same with “partititon wizard” (wrote new mbr) and now comodo bootmenue is away and i cant start CTM when i loged in. I become message: “critical error A…, please install new…”

(i do this all only for testing in a virtual mashine !)
Obvious: the critical error is the reset of the MBR, i.e., you’ve lost the console. Uninstall CTM, boot, install it again to have the console and the Windows GUI.
I have the same problem - after uninstall and reboot, CTM uninstall locks at 8%. Rebooting yields the same problem. I have run the Partition Wizard off a thumb drive and rebuilt the MBR - but now Windows Startup Repair is scanning and says it could take up to an hour to complete.
How could a problem this egregious and damaging be allowed to persist? I had faith in Comodo products before this, but not any more!
Whether or not this program is in development, THIS SHOULD BE FIXED.
