It started off with me extending the partition with partition wizard, trying to extend my c with unallocated space, it ask for a restart and my system is completely corrupted. Trying to use win7 startup repair and my c isn't even listed on the driver list. Unknown on (unknown) Local Disk. Tried the bootrec, bootrec /scanos doesn't work, can someone help me fix this?

Do you know if the previous disk layout was MBR or GPT? Can you use diskpart to see if the partitions are intact?


Try using the bootrec /fixmbr > bootrec /fixboot > then bootrec /rebuildbcd. Reboot.

I believe is was MBR, I tried the bootec commands and none work, the main issue now is that it can't locate my C drive is where the OS is install on

The MBR contains partitioning scheme information. Without fixing it, you'll never get your old C volume back. I'm afraid you've lost the old information and should go into the data recovery.


These issues are difficult to diagnose on a forums without all the information. You should explain the output of the commands and meta information about the disk. You can also clone the drive and take it to a shop to see if they can manage.

ok, I will just fresh install win7 then, problem is I will have my C drive where the OS is install on and a drive of unallocated space, I am trying to extend my C with the unallocated space, I can't use partition manager in win7 to this so I have to use a third party sw call minitool partition wizard, but if I do so I think my C will corrupt again. What do you think is making the system corrupt? Does manual restore point fix all BSOD?

Even if you're doing everything right, there will always be a small chance of breaking the install when shrinking or extending partitions. It comes with the territory.


Traditionally, you cannot span a Windows installation across multiple disks. https://technet.microsoft.com/en-us/libr...s.11).aspx You can extend a dynamic disk on the same drive though. That is probably the source of your corruption. Windows was telling you not to do so. :D I've heard of people doing so with hardware RAID, but never tried it myself.


BSOD is another topic. Can't tell without the dumps and stop errors.
