Windows 7 VHD magic: give the system a double insurance (1)

        Windows 7 (hereafter referred to as Win7) has added a new feature while streamlining a lot of features - native support for VHD (virtual disk) boot. But how can this function be used, and what convenience can it bring to our operation?

When it comes to the magic of VHD, let's start with the simplest and most practical: system backup. In the past, we used Ghost, Imagex and other software, but Win7 has native support for VHD, which is very different! Because the backup file we created is a VHD file, as long as it is set a little more Used by a separate system, this does not affect the normal backup operation, but also a new choice.

What is VHD:

VHD is the abbreviation of Virtual Hard Disk, which means virtual disk. When we use Virtual PC or Virtual Server software, we create VHD. file. Therefore, after being mounted in a virtual machine or system, it can be formatted, partitioned, etc., just like a normal hard disk.

Creating a Backup = Creating a VHD File

Creating a VHD file is as simple as clicking "Start → All Programs → Maintenance → Backup and Restore", then click left. In the side pane, "Create System Image", select an NTFS partition in the pop-up creation wizard (because the backup file is larger than 4GB, be sure to select the NTFS format partition and ensure enough space), then follow the prompts to select the system partition to complete. Backup can be done (as shown in Figure 1).

Tip: The "Create System Image" component backs up the system partition and boot partition by default, so if your Win7 has a 100MB hidden partition, the resulting backup includes two VHD files, you have to The size of the VHD file is differentiated and retained. In addition, only the Enterprise and Ultimate versions of Win7 support VHD booting, so if your system is not both versions, it cannot be started as a clone system.
