This How.com.vn teaches you how to clone, or "ghost", your Windows or Mac computer's hard drive. Ghosting a hard drive creates a backup of the hard drive's files, settings, and operating system; you can then use the backup as its own bootable drive on another computer. If you just want to create a backup of your hard drive that doesn't need to be booted from, consider creating a system image instead.

Things You Should Know

Make sure you have a hard drive that's at least as large as the drive you want to clone.
You can use Clonezilla to ghost a drive on Windows, and SuperDuper! to ghost a drive on a Mac.
To use Clonezilla for Windows, you'll need to install it on a USB flash drive and then boot from it.

1
Restart your computer into the BIOS. Click Start, click the Power icon, and click Restart, then immediately begin pressing your computer's BIOS key until the BIOS page opens.
- In most cases, the key that you press to access the BIOS will be either one of the "function" keys (e.g., F8), the Del key, or the Esc key.
- You can check your specific computer model's manual or online documentation to find the BIOS key to use.
- If your computer's "function" keys are inverted, you'll need to hold down Fn while pressing the BIOS function key.
2
Set your computer to boot from your flash drive. Each computer's BIOS will vary slightly, so check your computer model's documentation for specific instructions on setting BIOS boot order; however, in most cases, you'll do something like this:
- Select the Boot or Advanced tab at the top of the screen.
- Find the "Boot Order" section.
- Find your USB flash drive's name, then select it using the arrow keys.
- Press the + key to move the USB flash drive up to the top of the menu. If this doesn't work, check the key legend on the right side or bottom of the screen for explicit key instructions.
You'll usually do this by pressing a key that's listed in the legend on either the right side of the screen or the bottom of the screen.
When the first Clonezilla page loads, press ↵ Enter to proceed with the default settings.
Use the arrow keys to scroll down to the language you want to use, then press ↵ Enter to select the language and move on to the next option.
Press ↵ Enter to do so.
It's the top option on the following menu. Pressing ↵ Enter will take you to the next page.
This option is in the middle of the menu.
Doing so ensures that Clonezilla will take care of the more complicated settings.
This is the top option on this page.
11
Select the hard drive you want to clone. In most cases, you'll move the cursor to highlight the top hard drive; this is usually the sda hard drive (the "a" refers to the first hard drive). You can double-check that you're selecting the correct drive by looking at how many gigabytes of free space the drive has listed next to its name.
- A hard drive labelled "sdb" would be the second hard drive, "sdc" would refer to the third, and so on.
This will usually be the only option on the page, but check the hard drive's storage number (e.g., "500 gb") near the left side of its name to be sure.
13
Select -pa poweroff. This ensures that Clonezilla will turn off your computer when it finishes cloning your hard drive, allowing you to remove your flash drive before restarting your computer.
- If you don't remove your flash drive before restarting your computer, your computer will just reboot from the Clonezilla installation again.
Type y and press ↵ Enter when warned that the external hard drive will be overwritten, then type y and press ↵ Enter again when asked if you want to clone the boot loader.
This can take several hours. When Clonezilla finishes, it will turn off your computer.
This will prevent your computer from restarting from one of the USB drives; at this point, you can turn back on your computer and use it like usual.

Question
Can I ghost to a memory card?
Community Answer
I don't believe so. Only storage devices recognized as :drives" can be ghosted to - hard disk drives and solid state drives.

Question
What should I do if I want to do that in Notebook?
Community Answer
You have a few options with Notebook. If the book has 2 hard drive spaces then use the 2nd one, if you have an external hard drive you could ghost to that, put the new drive in and then ghost it back. Or you can buy an external caddy for your drive to ghost to and then just pop it in the book. External caddies these days are pretty cheap so it's probably the best option in terms of saving time.
