Windows 7: after system restore, new hard drive shows wrong size

That is odd. Can you post a screenshot similar to your last?

That OEM partition is still there - it must be the first partition on the drive (as it should be) and you misidentified it. That is why I asked for verification of the contents. So I don't know what you deleted. But It should work now from appearances.

Are you right clicking on the C: volume and selecting "extend volume"?

ok, deleted the OEM chunk and re-tried extend, same problem. Yes, clicking C: volume then selecting extend volume. Another screen shot of disk manager:

Well I don;t think you should have deleted either partition without knowing what it was for. I hope the one after C: wasn't significant, and the first partition would have still been useful as a DELL recovery partition now that it was identified as the OEM partition.

So, can you reboot your computer and try again? I am at a loss why you can't extend C: at this point.

I still have the original 50 gig drive sitting around and that's why i'm deleting mystery partitions at will.

Reboot and same issue < sigh >

Well, it looks like you may not be able to extend a boot partition in Windows 7 with the windows 7 disk management. See for instance:

Extending Boot Partition

where they recommend gparted. I would do some research before pursuing this route.

Problem solved. First tried Gparted boot cd and that was a waste. Stupid thing was complaining of errors related to "can't find Server X".

Downloaded MiniTool Partition Wizard (www.partitionwizard.com) ... I had to upgrade to Pro version for Merge capability ($29). Selected the 450Gb of unallocated space and did "create partition" which created new drive F:. After reboot, then launched tool again and did merge, with C: and F: and that worked fine.

So I'm thinking I might have been able to get this done with win7 tools by simply assigning a partition to unallocated space, then merge may have worked from Disk Manager. MiniTool Part Wizard was also unable to Merge when I only had unallocated space.
