What is Bare Metal Recovery?
Bare metal recovery (BMR) is a technique that enables you to restore a PC or Server without any requirement of previously installed software and operating system. "Bare metal" here refers to a completely blank hard disk.
To perform bare metal restore, you need a bare metal backup at first. It typically includes the operating system, settings, apps and even all the drives. With it, you can restore the same or different machine quickly and safely.
Advantages of Bare Metal Backup and Restore
BMR has many advantages compared with other backup solutions, the most important of which are probably the simplicity and safety.
◆ Simplicity: bare metal recovery avoids the complicated process of system and programs reinstallation, so as to minimize the computer downtime and save you a lot of effort.
◆ Safety: for a machine that has suffered a catastrophic caused by virus or ransomware, using bare metal restore also helps you to get rid of the infection source and potential threats.
With these benefits, bare metal recovery can be applied to many situations, like system or hard drive failures, virus invasion, hardware replacement, or even when you want to migrate physical machine to virtual machine, replace HDD with SSD, etc.
How to Perform Bare Metal Recovery in Windows PC and Server
Bare metal recovery can be performed both in Windows 10/11/8/7 and Windows Server 2012/2016/2019/2022, etc, and the preparations you should do are the same: a bare metal backup, and a bootable media like repair disc or installation disc.
Now I’ll introduce it in the following aspects:
Part 1. How to create a bare metal backup
To bare metal restore Windows 10/11/8/7 or Windows Servers with built-in utilities, you need a bare metal backup at first. If you've created it on this computer before, that's great. If not, or if this is a new hard drive or computer, you may need to create the backup on another normally working computer with the same boot mode (Legacy/UEFI).
★ Method 1. Create bare metal backup with WBadmin
Range of application: Windows 10/11/8/8.1/7 and Windows server 2008(R2)/2012(R2)/2016/2019/2022
You can customize the command by changing the target driver letter, drives you want to backup, and parameters of the backup. Detailed steps have been described in bare metal backup and restore with WBadmin.
★ Method 2. Create a system image in Backup and Restore
Range of application: Windows 10/8/8.1/7
Range of application: Windows 11
★ Method 3. Create bare metal backup with Windows Server Backup
Range of application: Windows Server 2008 (R2), 2012 (R2), 2016 or 2019
Windows Server Backup (WSB) was first introduced in Windows Server 2008 and came with a bare metal recovery feature. You can refer to how to create image backup in Windows Server Backup.
You can also create a backup image with easy-to-use bare metal backup software. To obtain more powerful and flexible features, go to Part 4.
Part 2. How to prepare a bootable media
To perform bare metal recovery, you need to enter Windows Recovery Environment with the installation CD. If you don’t have any, you can also create a bootable media by your own.
For Windows 10/11/8/7:
You can create a recovery USB drive or a system repair disc. There are some differences between them.
System repair disc can help you to access all Windows recovery options. You’ll need a CD or DVD to create it.
Recovery drive consists of essential Windows components and the environment. So in addition to getting access to Windows recovery options, it can also be used to reset or reinstall the computer. You'll need a USB drive that's at least 16 gigabytes.
For Windows Server:
Similarly, you need an installation CD or recovery disk to enter WinRE for Windows Server bare metal recovery.
If the target computer (the one you want to restore) has no system, you need to use Windows installation disk because system repair disc or recovery drive won’t work on the non-system computer.
A system repair disc allows you to troubleshoot problems on different PCs that run the same Windows version, while the recovery drive USB is only tied to the PC that you used to create it, unless the target computer has the exact make and model with exactly the same devices installed.
If you find these features complicated with so many limits, you can go to Part 4 to try an easier alternative with less restrictions.
Part 3. How to perform bare metal recovery
Before performing bare metal recovery, there are a few things you should know to avoid failures as far as possible, especially when you want to bare-metal restore another computer with dissimilar hardware.
◆ With the Windows built-in utilities, the original computer and the target computer should have the same boot mode, Legacy or UEFI. Otherwise, you will receive the error “System image restore fails because of EFI/BIOS”. Before performing Windows 10 bare metal restore or in other system, you can boot into BIOS to ensure the boot mode is the same or reconfigure it. If you change the boot mode, remember to convert disk into the corresponding partition style.
◆ Make sure the target disk that you want to perform bare metal recovery has enough disk space. If you want to restore to a new machine, the new hard drive should be in the same or larger size than the source disk.
◆ The target disk has to be formatted with NTFS.
★ How to perform bare metal recovery on Windows 10:
For bare metal backup created with built-in utilities, you need to enter WinRE for bare metal recovery. Here take bare metal recovery in Windows 10 as an example, please follow the steps below:
1. Insert the installation disc or recovery media to boot the computer that needs recovery.
2. Select the language and keyboard, then click Next on Windows Setup.

4. Select System Image Recovery and follow the wizard to perform a bare metal restore in Windows 10. If you create the backup with WBadmin, you can also perform bare metal recovery with Command Prompt.
5. Select the system image saved on a removable device or network location, and click Next.
6. Choose additional restore options and click Next.
7. Confirm the information, click Finish and then Yes to start bare metal recovery in Windows 10. It may take hours to restore and the computer will reboot automatically.
★ How to perform Windows Server Backup bare metal recovery different hardware:
To perform bare meta restore in Windows Server, you still need to enter the RE recovery environment. The steps are below. Here take Windows Server 2008 bare meta restore as an example.
1. Insert the Windows Server installation disc or recovery drive to boot the target machine.
2. Select the language and other preferences and click Next to continue.
3. Click Repair your computer to choose Windows Complete PC Restore from System Recovery Options. Optionally, you can select Command Prompt to restore WBadmin bare metal backup.
4. Select the bare metal backup you want to restore and click Next. If the image is saved on a removable devices, you should connect it at first. You can also select it from a network location.
5. Confirm the backup and click Finish to start restoring it to the bare hardware. It may take some time depending on how much data to be restored. Please wait patiently till the process ends.
Part 4. Easier alternative to bare metal backup and restore
Given the diversity of hardware and systems, it may not be difficult to do a bare metal recovery with built-in utilities, but there are many limitations and it is easy to make a mistake in one of the steps.
If you are finding an easier solution that can greatly minimize the possibility of failure to bare metal restore in Windows 10/11, Windows 8.1/8, Windows 7, Vista, XP or Windows Server 2003, 2008(R2), 2012(R2), 2016, 2019, 2022, a powerful backup & restore tool like AOMEI Backupper could be a better choice.
