Rescue Media...use with two computers

Can I use a Rescue Media Disk that was burnt from one computer and use it on a different computer?

 

I would suggest that you read the End-User License Agreement in the User Guide. In the case of True Image 9.0 Home Edition on page 3. item 2 it reads as follows:

END-USER LICENSE AGREEMENT
BY ACCEPTING, YOU (ORIGINAL PURCHASER) INDICATE YOUR ACCEPTANCE OF THESE TERMS. IF YOU DO NOT WISH TO ACCEPT THE PRODUCT UNDER THESE TERMS, YOU CAN CHOOSE NOT TO ACCEPT BY SELECTING "I decline..." AND NOT INSTALLING THE SOFTWARE.

The Rescue Media disk is an integral part of the 'software' and as such its use would be governed by this agreement. Perhaps Acronis support can add some additional information. The way I read it for use on two PC's you will need two copies.
