Can I delete the OEM and Recovery Hard Drive Partitions?

Hi,

I have an AlienWare 17 R2 laptop that I bought from Dell about 1-1/2 years ago.  It came with Windows 7 Professional pre-installed.  The hard drive has the following three primary partitions:

1. OEM Partition 39 MB
2. Recovery 10.20 GB
3. OS (C:) - 921.28 GB <= Windows 7 is installed on this partition

I would like to setup this computer for a multi-boot configuration that would give me the following OS choices:

1. Windows 7 (my existing installation)
2. Windows 10
3. Windows XP

I plan on using BootIT Bare Metal by Terabyte unlimited to help me create my multi-boot configuration.  I would like for my each of my three Windows versions to be on a dedicated primary partition, and I would like to keep my number of primary partitions to the typical PC/Windows limit of four.  To make this possible, I would like to delete the OEM partition and the Recovery Partition.

Can anyone tell me, considering I have a standard "Dell" or "Alienware" configuration, can I simply delete these partitions with no adverse side effects?  Or will deleting either of these break my Windows 7 installation?

Thanks in advance,
Paul
