I don't remember this boot partition with my older Win 7 laptops. These were consumer grade laptops. The one I have now is business class.

As ViRGE noted; since the release of Windows Vista to the present day, all Windows operating systems that use the default BIOS/MBR (Master Boot Record) partitioning scheme have contained [2] partitions. The "Boot" partition is (normally) assigned drive letter C:\ . When you open Windows Explorer to browse your operating system folders you are looking at the contents of your Boot partition.
The other partition, called the "System Reserved" partition, is not assigned any drive letter. Thus, it isn't visible in Windows Explorer and is called a "Hidden Partition". The System Reserved Partition (see below) contains the Boot Manager and the BCD (Boot Configuration Data). The BCD contains all the information that the Boot Manager uses in order to boot into the Windows operating system.
Windows 7/8 dual-boot configuration, but note that the System Reserved partition has no drive letter:
The problem you've created for yourself was failing to configure Acronis to backup the hidden System Reserved partition. The only way you'll restore your operating system is to get out your Windows 7 installation DVD (if you don't have a copy, ISO download links are
HERE) then follow these instructions on
How To Rebuild the BCD in Windows. If your laptop doesn't have an optical drive; download the Windows 7 ISO version you need, and then use Josh Cell's excellent
WinUSB Maker to easily create a bootable Windows 7 USB flash drive installation.
