I'd use PW CD to Modify>mark Active/Inactive as well - it's easier.

Then you can do the conversion.

When I try to install Partition Wizard 4.2 on my computer, I get the message, "Application cannot run in win32 mode". The way around this would be....??????

The (Jonathan King) download link for PW4.2 is a zip file. Once unpacked you get a number of supporting files (dlls etc) and an executable. Pwiz.exe. Double click should launch the application. It works for me on Windows 7 x64 and XP x32.

It is not a bootable version. For dynamic to basic disk conversion bootable versions are not desirable anyway.

Ok, So far so good.... Now, one last thing. I have a disk with no drive letter and I KNOW it has data on it cause there are still files I cant find. Ive attached a snippet of my computer management screen. Any ideas how to get THIS back. FYI EVERYTHING has worked so far!!!!!!!

Right click the HDD and see if the "change drive letter" option is greyed out.

Yes, its available however when I try to click on it I get the message that says "the operation failed because the disk management console view is not up-to-date. refresh the view (tried that) or close console then restart or reboot (tried those). Suggestions ??
Thanks for ALL the help!!!!!

You can use Partition Wizard for this operation, even rightclick Explore the partition to make sure files are there (you cut listings off the top of your screenshot).

If not, use Recover Partition Wizard on PW.

Sometimes Disk Mgmt is wrong, even PW Windows version. The solution is PW bootable CD to settle which is correct.

There is no guarantee in performing these types of operations that your data will not be lost. It should have been backed up before hand.

I don't think a primary partition has been created

Go back into partition wizard.
Try (A)
right click partition>modify>set partition primary
right click partition>change drive letter
if this succeeds your probably done.
If not you need to run the PW data recovery wizard.

Try (B)
See option 4 of the tutorial
Convert a Dynamic Disk to a Basic Disk

You should be able to use ver 4.2 and you shouldn't need a bootable PW for this.
ver 4.2 downloaded was never bootable.

Ok, So, one last question. I have removed the data from the hard drive that has the unmarked partition on it. Would in be better to boot into Partition wizard and format the drive to hopefully get it all compacted together again or just as good to run the format with partition wizard from the windows 7 gui?? in the attached png.....drive H and the unlabeled disk 3 are all the same hard drive.
