Windows 7: Partition Magic destroyed my partition.

17 Dec 2010   #1

Windows 7 Professional 64-bit
Partition Magic destroyed my partition.

Situtation: I have one hard drive in my laptop, split into a C: partition for my Win7 installation, and D: partition for my files and documents. Used Partition Magic without thinking; ignored compatibility warnings like a fool, etc etc.

My D: partition disappeared, C: seems to work fine.

I've been trolling the internet and tried to use TestDisk, but the problem is that TestDisk guides are under the assumption it will just ask you to fix your partitions. Didn't happen that way for me - the Quick Search didn't find D, however TestDisk's "deeper search" for some reason shows the missing D: partition as a normal, existing, primary partition and C: as deleted. This is obviously not the case, so I didn't know what to do.

If it's worth anything, TestDisk did mention that the two partitions were overlapping with each other. Other recovery software such as EasyUs Partition Recovery didn't work either and showed me the same result (it can't recover overlapping partitions)

Any tips on how to fix this? The data is still there, I can see it using file listing in TestDisk, I just don't know what to do to fix it.

Edit:// Before anyone asks, yeah, I've seen D: drive missing in win7 due to partiton magic. Doesn't help, because again, TestDisk doesn't just magically find my partition during Quick Search and lists the wrong partition as "deleted" during Deeper Search.

Welcome to SF!
  • Download Partition Wizard
  • Create a Boot Disk
  • Partition Wizard has an option to Recover a Partition.

Give it a try- maybe you'll get lucky?

Well, I have a little update. I used EASEUS Partition Master to resize my allegedly "overlapping" partitions. Reduced the size of the C drive and increased the size of the D drive, as well as gave it a label of D:. It did it successfully.

New problem - my computer will not boot into anything except the Dell Diagnostics partition.

Hopefully it's just a matter of switching the Active partition back to my C: partition, but if anyone has any tips on how to do that or suggestions for free software to use, I'd appreciate it.

I've never had to manually set a partition as active in my life, but perhaps that's the problem here. You also might be able to fix it by repairing the boot options with your Windows 7 DVD. As for the first suggestion, Partition Wizard's boot disk, mentioned above, should let you see what is active and set that option accordingly.

So I fixed it. Here's what I did:

1) Used Partition Wizard's Bootable CD to resize the partitions till they didn't overlap.
2) Used Partition Wizard's Bootable CD again to change the Active partition to my Windows installation (C)
3) When encountered then with "BOOTMGT MISSING", I burned a Windows Repair Disc and clicked Startup Repair (only needed to do it once)
4) Because my drive letters had changed I used this procedure to change them back and fix any program associations (i.e. Dropbox, etc.)

Aaand boom! Screw TestDisk, viva gui! Thanks to you guys who replied, +rep for all!

We all know Partition Magic is obsolete. But they still peddle it for Windows7. Not good.
