NEED HELP! CTM is stuck on startup after uninstalling


Comodo Time Machine is stuck on startup after uninstalling…

There was an error come from nowhere when uninstalling the CTM after reboot.

Now, MTC has blocked my computer, it refuses to boot … I’m stuck on a black screen with a flashing white in the upper left. Sometimes it stays there forever, sometimes my computer shuts down by itself after 5 seconds the black screen appears.

Format is unthinkable.

I need to unlock the boot. How??

My computer is a HP, with Vista.

Thanx … Sry for my bad english.

How did you uninstall CTM? Into Windows and then boot?
I’m not experienced yet on recovery from such situation. I’m also learning (although CTM uninstalled twice from my computer without problems).

Yes, on Windows, directly from the setup Uninstaller CTM.

I found this topic

Can someone tell me explicitly what to do to use the tool suggested to solve the problem?

I have to download it, put it on a CD? A CD of what kind? and How?


I’m learning as you… so don’t take my words as an experienced user (yet).
I think you can use its MBR (Master Boot Record) Tools.

Hiren's BootCD 10.4 and its MBR (Master Boot Record) Tools - BootSect 6.0.6: Boot Sector Manipulation Tool, This tool replaces FixFAT.exe and FixNTFS.exe (Windows Freeware). - DiskMan 4.2: all in one tool for cmos, bios, bootrecord and more (Windows/Dos Freeware). - Grub4Dos installer 1.1: an universal boot loader GRUB for DOS installer (Windows Freeware). - MBRWizard 2.0b: Directly update and modify the MBR (Master Boot Record) (Windows/Dos Freeware). - MbrFix 1.3: To backup, restore, fix the boot code in the MBR (Windows/Dos Freeware). - MBR Utility 1.05: to manipulate a drive's master boot record (MBR) via the command line (Windows/Dos Freeware). - BootFix Utility: Run this utility if you get 'Invalid system disk' (Dos Freeware). - Boot Partition 2.60: add Partition in the Windows NT/2000/XP Multi-boot loader (Dos Freeware). - MBRWork 1.08: a utility to perform some common and uncommon MBR functions (Dos Freeware). - MBRTool 2.3.200: backup, verify, restore, edit, refresh, remove, display, re-write... (Dos Freeware). - MBR SAVE / RESTORE 2.1: BootSave and BootRest tools to save / restore MBR (Dos Freeware). - Smart Boot Manager 3.7.1: a multi boot manager (Dos Freeware).

But look, YOU CAN LOST YOUR DISKS IF YOU DO ANYTHING WRONG. Read their manuals, check back here in forums. When I learn how to deal with it, I’ll post.

Another option is Ultimate Boot CD adding the TestDisk tool as you’ve posted before.

  1. Download the DOS version of TestDisk at
  2. Download FreeDOS at
  3. Unzip FreeDOS to folder FDOEMCD (it will do that by default)
  4. Unzip TestDisk to the CDROOT folder (it’s a sub-folder in the FDOEMCD folder)
  5. Rename the testdisk-6.11.3 folder to testdisk
  6. Open the AUTORUN.BAT file in folder CDROOT
  7. Add the following two lines to the AUTORUN.BAT file:
  1. If you like, then you can change the mkisofs.rc file to give the CD some recognizable boot screen info. This step can be skipped if you like though
  2. Go to folder DFOEMCD and execute the next command:
mkisofs -o testdisk.iso -p "Drakenine" -publisher "" -V "TestDisk CD" -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -N -J -r -c boot.catalog -hide boot.catalog -hide-joliet boot.catalog CDROOT

What you have now is an ISO file which you need to burn to CD. If you did that, then put the CD in your CD/DVD drive and reboot your system. After some time TestDisk will start. You can now follow the steps as explained in TestDisk Step By Step - CGSecurity. You should start at step TestDisk Step By Step - CGSecurity and then go your way down.

Good luck and I hope you succeed in recovering your drive.

PS: Most of this info is taken from the cgsecurity wike (Partition Recovery and File Undelete)

System cannot execute this command.
Even mkisofs.exe does not work. Even running in at admin command line does not work.

I have a simple approach. I’ve made a multiboot USB Flash drive from here and I put some ISO’s on it (FreeDOS, memtest, PartedMagic, Macrium free) and some exe’s (HDDErase and TestDisk). Works like a charm for firmware/BIOS updates or anything else.
You can add your ISO’s and/or any exe which works under FreeDOS.

Oops, I forgot that it only works on a 32bits windows machine. I don’t know if they have already a 64bits version available.

Up !

Can I be helped by the staff plz?


Which version of CTM are you using?

Thanks & Regards,
