Can I "load" XP software using Win 7/Pro  

I have a Belkin battery backup system (UPS) that has some software (Belkin Bulldog Plus Monitor) that monitors the computer and AC power, and, in the event of the loss of AC power, puts the system in hibernation.

This worked really well under XP; alas, I've migrated to Windows 7/Pro (64-bit). Belkin has no Windows 7 support (indeed, they have withdrawn from the UPS market).

Is there a way I can get the XP Mode to startup as part of the boot process, and, as part of it, get the Belkin software to load? If I were successful in that, would issuing the hibernation command be limited to hibernating the XP VM, or would it apply to the overall Windows 7 environment?

Yes you are Able to do that If you have a Partition
1. If You Have Partition You will be able to Through the Opposite Operation System, Through "My Computer, C:// Is the One you are Using at that Moment, so pick D://Program Files, Then find the Software like Minesweeper or Movie Maker..

Or 2 other way's..

Use a USB And Find a PC with the OS On

or Get a Virtual PC and install XP On that with the Virtual Picker
