I've read numerous articles that dance around this topic but haven't found anything specific about what I want to do. I have a brand new Lenovo desktop with two SSDs installed. It came with Windows 7 preinstalled and I've been using the machine for a couple weeks. Disk 0 contains the C: drive, which boots the machine. Disk 0 also contains a partition called "Lenovo_Recovery". Presumably I'd want to keep this in case things ever go bad. It also contains an "EFI System Partition". Can I use DISKPART to delete the EFI System partition and subsequently expand the main partition into this space and lose neither the data on my C: drive nor the ability to boot from it?
I haven't messed with partitioning disks since the DOS days (when a 40 MB hard disk was huge) and I'm just not sure what's possible now. I barely understand what EFI is or does. For what it's worth, I don't foresee ever booting multiple operating systems on this machine.
This question seems to ask the same thing, but the asker was planning to reinstall the OS. I don't want to do that.

The DISKPART utility shows this:
