NTFS fi le systems. Other Windows operating systems use FAT16 or FAT32 and cannot
recognize NTFS. All Windows-based operating systems can recognize FAT partitions.
If you will dual-boot with Windows 9x, you must turn off disk compression or
Windows 7 will not be able to read the drive properly.
Do not install Windows 7 on a compressed volume unless the volume was compressed
using NTFS compression.
Once you have installed each operating system, you can choose the operating system
that you will boot to during the boot process. You will see a boot-selection screen that asks
you to choose which operating system you want to boot.
The Boot Confi guration Data (BCD) store contains boot information parameters that
were previously found in
boot.ini in older versions of Windows. To edit the boot options
in the BCD store, use the
bcdedit utility, which can be launched only from a command
prompt. To open a command prompt window, you can do the following:
1. Launch \Windows\system32\cmd.exe.
2. Open the Run command by pressing the [Windows] key + R and then entering cmd.
3. Type cmd.exe in the Search Programs And Files box and press Enter.
Once the command-prompt window is open, type
bcdedit to launch the bcdedit utility.
You can also type
bcdedit/? to see all the different bcdedit commands. A few bcdedit
commands may be needed when dual-booting a machine. Table 1.5 shows some of the
bcdedit commands that may be needed when dual-booting.
