As long as you are not crossing the 32-bit/64-bit line, you should be able to use the Recovery Drive that you created on your HP and use it to boot up your Lenova. Keep in mind that the Recovery Drive only boots up the PC and provides access to a host of repair tools. If you are going to perform data recovery/restoration, you will need system specific data. For example, you can launch and run System Image Recovery from the Recovery Drive, but of course you will have to use the image created for the Lenova. Stay tuned as I will explore using the Recovery Drive next week.

Disk Encryption is something I have not yet explored but will do so in the future.

Yes, the optical disc (CD/DVD) and USB flash drive Recovery Drives are bootable devices. I did fail to mention that in the article... I made the assumption that people would know. (EDIT: Actually I did mention in the introduction to the article that the Recovery Drive will allow you to boot your system... but I suppose that I could have elaborated a bit more.) I apologize for any confusion.

In the future, I plan on mercilessly killing a Windows 8 PC over and over again and showing how to use the tools on the Recovery Drive to aid in fixing it.
