Can't start CTM or Windows

I did a system restore using CTM on my Windows 7 Pro 64-bit HP laptop and it appeared to restore things properly. I was able to reboot several times and things looked great.

I then went into the CTM application through Windows and decided to set a new Baseline. It prompted for me to reboot, which I did, and CTM then started to create the Baseline. The progress gauge showed that it would take about an hour or so. After a couple minutes it was at 1%, so I left it and went to bed. I came back this morning, and it was stuck at 2%.

I powered down and rebooted, and CTM came back up saying that it was unable to verify the tables. I pressed OK and it started creating the Baseline again. It then threw up some errors about unable to read sectors. I clicked “Ignore All” to try to exit and it said “Too many bad sectors” and then froze.

When I reboot, it goes through the same cycle of trying to build the Baseline and then errors out, freezing the system. Now my system is in a condition where it can’t get past CTM into Windows.

I want to use CTM, but it sounds like I need to get into Windows, uninstall CTM, and then re-install, however I can’t get into Windows.

Suggestion?

Hi… I understand your issue, but you didn’t mention which version of CTM you’re using though. ( I assumed it’s 2.8 )

Did you try hitting “Home” key after Bios check-up to see if you could get around the “Error cycle” ? If you could get to the boot-up console you should uninstall CTM first. If you can’t get out of the error-cycle the Only sensible thing left to do is to rebuild MBR. ( By doing so, you will clear CTM’s path on the Master Boot Record )

It is version 2.8 (whatever the latest build is from about 3 weeks ago.)

I’ll try that, but if I recall correctly, it goes to the “building snapshot” phase regardless. If that’s the case, I’ll try rebuilding the MBR.

Fortunately, I have a Windows Home Server that the laptop gets backed up to nightly, so I could do a full restore from that if necessary, but my guess is that I’d need to restore to a version PRIOR to when I installed CTM.

I have the weekend to tackle this…

Right, in that case you could choose between rebuilding MBR or restoring a back-up image from your Server. If you choose the latter, just restore it back to the point before you tried to set a new baseline.

Suggest you install the 2.9beta version if you should decide to install CTM again, it has a new snapshot engine and lots of prior bugs have been fixed in this version, which could be found inside the " Beta Corner ".

After trying it out do come back and share your view of this latest version.

James, thanks for the info. That’s what I needed.

Despite the many negative comments and feedback on this forum about CMT, I really do want CMT to work. It saved my ■■■■ twice, and I’d like to give it the opportunity to do so again. ;D

Once I get things restored, I’ll try installing the new beta version.

hi there.thank your for your replys
I have the same problem as Jim described but slightly different.after googling a lot I found these two topics which are relevant to my case
https://forums.comodo.com/bug-reports-ctm/ctm-fails-after-installation-t51507.0.html
and current topic which I’m writing in
https://forums.comodo.com/help-ctm/cant-start-ctm-or-windows-t68911.0.html

disciption:

As Jim did I installed CTM (i had no previous identical software installed).I had it for a week and it was good until i decided to reset base line from CTM control panel in windows.it requested reboot and was granted :smiley:
after shutting down it came up after bios check to create new base line.the bar filled up several times (creating defragmenting) and last time filled to 70 percent and froze. I waited an hour,no progress.so i rebooted using ctrl+alt+del and now I have the problem
every time the computer boots it goes to screen shot I attached and freezes at 0 percent.after a while says

Failed to read v-sector (lab lab lab, lab, lab lab lab) error code 400, DiskNum 0.
options are "ignore" "retry" "ignore all".if I ignore all the error "too many bad sectors" is thrown again. pressing home and trying to go to CTM console leads to "too many bad sectors" so i don't have access to console after pressing the "enter" button (accepting error too many bad sector) the frozen 0% bar came up to 21 %

questions:

  • is there any other solution than pressing enter to fill this bar and return to windows?
  • I have two 1TB hard disk and one 500 GB one mounted.does it take time to fill the bar of creating new base line for all of them.
  • what If i fix MBR via windows recovery console (bootrec.exe /fixmbr) and wipe the track of CTM from boot sector.is there risk of data loss.
  • I have the opportunity to re install windows.if I do so,does CTM deletion in this way affect my data in other disks and partitions?or remaining of undeleted snapshot data which wastes my free space?

Hi,

is there any other solution than pressing enter to fill this bar and return to windows?
You should rebuild the MBR to get rid of CTM if it gets froze repeatedly on re-boot.
I have two 1TB hard disk and one 500 GB one mounted.does it take time to fill the bar of creating new base line for all of them.
You didn't mention if all the disks were protected by CTM or just the system disk. It should not take much time to reset the baseline.
what If i fix MBR via windows recovery console (bootrec.exe /fixmbr) and wipe the track of CTM from boot sector.is there risk of data loss.
There is a slight risk of data loss on the CTM protected disks.
does CTM deletion in this way affect my data in other disks and partitions?
It should not affect your other disks/partitions at all if they were not protected by CTM.
or remaining of undeleted snapshot data which wastes my free space?
Once CTM is uninstalled by it's own uninstaller or by rebuilding the MBR, all the snapshot data would no longer be secured and all the occupied space would be freed up.

Hope these help ! Good luck. (If install CTM again, try 2.9beta)

thanks buddy.your post was great and helpfull.
I accepted the risk and rebuilt the MBR via windows recovery console by this guide

http://www.sevenforums.com/general-discussion/17521-how-fix-mbr-through-command-prompt.html

windows booted up normally and I saw my lovely desktop.
things were ok on all disks but the one which contained system drive.
the Disk which contained system drive has been reverted to it’s state before I installed CTM.I mean I lost the data which i had added after installing CTM (fortunately I had backups on another PC)

Glad to be of help !

the Disk which contained system drive has been reverted to it's state before I installed CTM
That's expected of CTM version 2.8, and with CTM 2.9beta your system would be left with current state after rebuilding the MBR.

thanks for replies and tracking the tread.

that's a very good change.if I use CMT again I would use 2.9beta or above.
