I have a laptop that currently is running Windows 7 Home Premium 64-Bit.  I would like to set this laptop up to dual boot with Windows 7 Home Premium 64-bit and Windows 7 Professional 64-Bit.  Unfortunately, I don't have the media for the Windows 7 Home Premium OS.  This laptop was purchased and the OS was OEMed.  Someone told me that Windows 7 has the capabilities of repartition the hard-drive similar to a Partion Magic software.  So here are my questions:

1.  Can I use the existing Windows 7 Home Premium install to repartition the hard-drive to carve out some space for the Windows 7 Professional install?

2.  Once I have the space carved out, what is the proper procedure or necessary tricks to have this laptop dual boot?

Thanks

This is fairly simple to do right from Windows.

Right-click on Computer, Manage, Disk Management.  Right-click on the partition you want to make smaller, and choose Shrink.  A wizard will start to show you how much space you will gain by doing this.

Then, install Professional to the newly available Unpartitioned Space ... it will automatically be added to the boot menu.

Note, however, that setting up a dual-boot system will probably damage your system's Recovery Partition (the partition that restores your computer to factory condition in the event of a Windows failure - this is what they give you now instead of the installation disks), so I would be proactive and order the disks from your laptop's manufacturer.  Should you ever have to reinstall, the recovery partition will not work and you will only be able to use the disks.

You can also probably create your own recovery disks from within your OEM version of Windows.

Make/model if you need more specifics.

This worked great but I only have one more question.  Now that I have the dual boot setup, when the laptop initially boots, I get the screen showing two boot options.  Unfortunately both options say "Windows 7" and that is all.  I would like to distinguish these between Home & Professional.  If I recall correctly, this setting used to be under teh BOOT.INI file in XP.  I couldn't seem to find this same file on the Windows 7 installs.  Where can I edit these names so they are distinguishable?

You can't edit it directly in Vista/7 ... need to use BCDEdit, which is part of Windows ... but it is command line.  It is much simpler to download and use EasyBCD to edit the actual entries in your boot list.
