Reformatting a drive

Dense, I tell you. Hahaha. Take 2.

@DocBrown Did exactly that. Stored my back up in D

Looks like you've ruined your Recovery Partition. If you haven't already made your Recovery disks then try now making them from whatever Recovery link you have in Start>All Programs. If you'll tell us the brand PC we can help you with that. You might also be able to restore it by moving all of your personal files out of it so it has enough empty space to run from boot or when triggered from All Programs, or to make your Recov disk.

If not then if you have made your disks or you don't want Recovery anyway you might as well delete both the D and OEM partition - unless it's Dell or HP and the bootable Diagnostics will still run via the ESC (HP) or F12 (Dell) key at boot. Try them now.

You can delete D in Disk Mgmt Partition or Volume - Delete,

but will need to delete OEM using Delete and Remove to Unlock EISA Hidden Recovery or Diagnostic Partition in Vista « My Digital Life.

Then you can create a storage partition in the joint space using Partition or Volume - Create New. But remember that its safest to back up your files and a Win7 backup image externally in case of HD failure, or to the cloud like this: https://www.sevenforums.com/backup-re...ml#post2269172

Also be aware that the factory preinstall of Win7 is corrupted by the bloatware and duplicate utilties so I would strongly suggest you do what other tech enthusiasts do to Clean Reinstall - Factory OEM Windows 7. At the minimum I'd Clean Up Factory Bloatware

I think I'll try deleting only 'cause it's the simplest. The rest is a bit confusing...Doing it now

So you don't know your PC brand?

Have you made your Recovery Disks? If not your options if you delete will be to order them from Tech Support if you want to ever run Factory Recovery, or do the superior Clean Reinstall - Factory OEM Windows 7.

If your PC isnt' Dell or HP which still have bootable diagnostics, then the OEM partition is wasted space you could be using.

Got gumption to work with us to sort this out?

@Gregrocker Well if you put it that way. Sure, I'll wade through the tech jargon. So I need to create a back-up, right? Btw, I have a Lenovo :)

@DocBrown I think the deletion worked. But not sure.
