Drive no longer boots after converting to Dynamic

    Drive no longer boots after converting to Dynamic


    I wanted to use drive mirroring which requires changing the drives to dynamic however before I did that I wanted to be sure the conversion would leave the drive still bootable and that there would not be any data loss so posted on Technet.Microsoft.com and was advised I could convert to dynamic without any data loss and the drive would still be bootable. To be on the safe side I cloned drive C to the drive that will be the second drive in the mirror setup and then converted drive C to dynamic. All went fine and after exiting dish management everything was working fine so went back into disk management and coverted the other drive to dynamic as well which again seemed to go just fine. It showed both drives as dynamic and healthy and drive C as a bootable system drive.

    I shut down and restarted however as soon as it started to reboot there was a message saying Preparing Automatic Repair and then Diagnosing PC and then Attempting repairs. Then I get a message saying automatic repair couldn't repair your PC with two options, shut down and advance options. Selecting advance options brings up another screen with three choices. The first is continue which if you select it it just reboots. The third option is turn off your PC. The second option is troubleshoot and selecting it brings up another screen giving three choices, Refresh your PC, Reset your PC and advanced options. I don't want to have to reinstall all of my software which I would assume I would have to do if I select either of the first two options but would appreciate if someone could confirm that. The third option is again advance options which takes you to another screen with six options. System restore, System Image recovery, Startup repair, Command prompt, UEFI Firmware and Startup settings. Selecting system restore brings up an error saying system restore could not find the offline boot volume. Please insure it is currently accessible. I don't have an image recovery, startup repair does not solve the problem. Selecting command prompt and then going to drive c: shows a 16 GB partition named Samsung Rec 2. Going to Drive d: shows Samsung Rec which is 325 MB, so assume these two partitions were the recovery partitions. It would appear the original system partition that had all of my files as well as the system files, in other words the primary partition on drive c is now drive X so am not sure if that is the reason it is not booting or what I need to do to make it bootable again.
    Thank you

    Yeah, that happens...

    The key is to have the system boot off a basic drive from a separate System Reserve Partition.
    Since you're well past that see if this tutorial gets your machine back in shape.

    Read though it carefully, understanding all of the caveats (pay attention the warning, tip and info colored boxes)

    If you have any questions - ask FIRST.

    Thank you for the reply and I had already read that post and tried it however get a message that says failed to convert the specified dynamic disk, but no other explanation.

    The display of mine is pretty much the same as what is shown in the tutorial that is posted except under type mine is shown is GPT and the tutorial shows logical, and my drive is larger but what is shown is correct for my drive.

    Did you use PW 4.2?

    Minitool dropped the Convert Dynamic to Basic function from the FREE Home Edition of Partition Wizard sometime after 4.2

    The ISO for PW 4.2 is lited in step 2 of the tutorial.

    Let me know.

    Any suggestions for a free program to write the ISO to a USB drive? I downloaded Imgburn and understood it wrote to CDs and USBs but it appears it only writes to CDs.

    Thanks

    Never mind, downloaded ISO to USB so will let you know how I make out.

    The version I used was 4.2 so I believe that version still had the capability to convert.

    Free buring utility? Windows 8 - burn to disk.

    No 3rd party software needed.

    To create a bootable Flash drive - I use Rufus
    https://rufus.akeo.ie/

    um... if you're asking questions about how to burn an ISO, then I'm not sure you used PW 4.2 before. If you did, it wasn't from a bootable disk.

    You're changing the drive schema, so you can't do that when Windows is running.

    Try booting to the PW 4.2 disc. You'll probably have more success (at least I hope you will )

    edit: I suppose a bootable USB thumb drive will work as well - if not try a bootable disc. I don't see where it makes much difference (although some utilities require FAT32 and some utilities write NTFS to thumb drives). The UDF format of discs don't have those same issues.

    I hope it works with the USB so you don't have to burn a disc, but if it doesn't - try creating a disc.

    The tutorial at sevenforums has a link to download both the Windows Partition Wizard 4.2 and the ISO. I downloaded the 4.2 and ran it from my VISTA laptop with the drive connected through a USB port on the VISTA machine. There is also free verion of version 9 which I tired after 4.2 didn't work and the messaqe from it was that feature is not available in the free version. I had also downloaded the ISO but so far have not had any success in getting it too boot so will try the program you suggested if that still fails may have to run over and buy some CDs and burn it to one of them.

    My only Windows 8 machine is the one that no longer is bootable. My old laptop that I am using right now is a Vista and my desktop is a Windows 7.

    I used the ISO to USB but it will not boot. I tried make bootable option and without the option but will still not boot from the USB drive so not sure what I have done wrong or why it won't boot. It I go into the setup it is set to boot from the USB first on both computers I have tried it in. In the one with the drive that needs to be fixed it is like it doesn't even see it and in the Windows 7 machine it goes through the normal POST and then says remove any disks and press any key to restart and when you do that it boots into Windows 7. Not sure what I am doing wrong unless when it writes the drive it should be NTFS but still not sure whether to make it bootabl. I assume the ISO will make it bootable but would appreciate your input on the correct parameters for writing the ISO to the USB.
    Thanks

    Good tool to know about - have you run it before?

    Thanks I've added it to my tool box and will try it at some point.

    Jack, I've never used the EASEUS tool, but I trust KYHI to only recommend a good tool. This might be easier than trying to get the 4.2 PW to work.

    The directions look fairly straight forward - read it over and give it a try Please let us know the results.
