Installation and Configuration
(The following procedure uses Windows XP as the example operating system.)
A. Installing Windows XP and Partitioning the Hard Drive
1. 2. Set CD-ROM drive as the first boot device under "Advanced BIOS Features" in the BIOS Setup program. Save the changes and exit. When partitioning your hard drive (Figure 1), make sure to leave unallocated space for Xpress Recovery2 (10 GB or more is recommended; actual size requirements vary, depending on the amount of data) (Figure 2).

Figure 1 3.

Figure 2
Select a file system (for example, NTFS) and begin the installation of the operating system (Figure 3).

Figure 3

- 64 -
After the operating system is installed, right-click the My Computer icon on your desktop and select Manage (Figure 4). Go to Computer Management to check disk allocation. Xpress Recovery2 will save the backup file to the unallocated space (black stripe along the top)(Figure 5). Please note that if there is no enough unallocated space, Xpress Recovery2 cannot save the backup file.

Figure 4 5.

Figure 5
If your hard drive is not properly partitioned before you install the operating system, you may create new partitions using free space on your hard drive (Figure 6, 7). However, if Disk Management shows the hard drive only contains the System partition without any unallocated space, you will not be able to create new partitions or use Xpress Recovery2. If this occurs, reinstall the operating system and re-partition your hard drive.
Figure 6 In the New Partition Wizard, you MUST select Primary partition. This will reserve unallocated space for Xpress Recovery2 to use.
