If you are troubled with the error that cloned to new computer Windows 7 won’t boot, you can learn how to fix the error and restore Windows 7 image to different hardware stably from this page.

An error occurs: clone to new computer Windows 7 won’t boot

When we buy a new computer, it is needed to clone all the data on the old computer to the new one. Nevertheless, after cloning the operating system from the old computer, the new computer fails to boot. Why does this happen?

If you find Windows 7 won’t boot after cloning to new computer, different boot modes on the two computers and corrupted boot records may be responsible for that. At this time, you are supposed to check and repair your new computer so that it can be used again. What’s the specific solution?

How to solve cloned to new computer Windows 7 won’t boot easily?

I’ll show you a quick fix to cloning Windows 7 to new computer not booting caused by different boot modes on the two computers and corrupted boot records separately.

Reconcile boot modes

Please affirm the boot mode on the old computer first. Do like this:

1. Right click the “Computer” icon on the desktop and hit the “Manage” option.

2. Click on “Disk management” to open Windows Disk Management. Right click on Disk 0. If there is “Convert to MBR Disk” option in the pop-up menu, then the old computer is in UEFI boot mode; if not, it’s in Legacy BIOS.

After figuring out the boot mode on the old computer, continue to check the new computer’s boot mode in following steps:

1. Start the new computer and tap Del to enter BIOS interface.

2. In the BIOS Utility dialog, select Boot > UEFI/BIOS Boot Mode. See whether Legacy or UEFI is chose under the option.

3. If the boot modes are the same on the two computers, you should do nothing; if not, change the new computer’s boot mode to make it accord with the old one.

Your new computer may become bootable after you reconcile boot modes on the old and new computer. However, if the error still exists, try the second solution below.

Repair boot records

Corrupted boot records can also lead to the error that cloned to new computer Windows 7 won’t boot. In this case, you should follow the guidance below to repair boot records:

2. Use the arrow keys to select Safe Mode with Command Prompt and press Enter.

4. Exit Command Prompt and restart your computer. 

A more stable way to restore Windows 7 image to different hardware

Some users are frustrated with the boot issue after cloning Windows 7 to dissimilar hardware. Here I’d like to recommend a more stable way to restore Windows 7 image to different hardware. AOMEI Backupper Professional built in with backup, sync, recovery and clone features comes to help. It enables you to do system backup & restore, disk clone, real-time sync, etc.

Before you restore Windows 7 to new computer, you should backup Windows 7 to USB and create bootable media via AOMEI Backupper on your old computer. Then, follow the steps below:

Step 1. Connect the bootable USB flash drive with Windows 7 backup image to your new computer. Boot from the USB by changing boot order in BIOS.

Step 2. You’ll see loaded AOMEI Backupper once login. Select “Restore” on the left pane and tick before “Universal Restore” to ensure the system is bootable after recovery. Select the system backup task to restore and click “Next”.

Step 3. Select the latest backup point of your system backups and click “Next”.

Select Backup Point

Step 4. Confirm operations on the “Operation Summary” page and click on “Start Restore” button.

Start Restore


If the size or location of the original system drive has changed, you will need to specify the destination drive before Step 4; if not, the program will automatically select the current system partition (usually C drive) as destination drive. You can also change the default destination drive by ticking before “Restore system to other location” in Step 3.


By reconciling boot modes and repairing boot records, you can solve the problem that cloned to new computer Windows 7 won’t boot. What’s more, you can use AOMEI Backupper to restore Windows 7 image to different hardware, thus avoiding the error.
