ATI 2016 Backups.

Restoring of backups is recommended to be done with the computer booted using a user created Recovery Media which can be made to a DVD/USB.  Recovery is not recommended to be done from within the Windows environment for OS system disks as this requires the application to reboot the computer into a Recovery environment (Linux based) the same as that of the created Recovery Media.

For recovery of other than a Windows System OS disk such as data only drives or files or folders recovery can be and is recommended be done while booted into the installed Windows and running the True Image application.

Not sure what you mean.

I purchased ATI 2014 and 2015 for use with Windows 8.1 and Windows 10, but had to return both products for a full refund.  Neither one could restore the backups it had just created.  Every time I tried to restore a backup ATI would hang up with the following following message: "Starting Acronis UEFI loader...."  But the loader never would start, and True Image could never restore any of my backups.

When I contacted ATI technical support, they told me that the only way to restore a backup was for me to go into the BIOS settings and disable the UEFI secure boot function.  Now Microsoft created the UEFI secure boot function (used in Win 8.1 and Win 10) for a reason - to prevent root-level hacking/virus attacks.  Why should I have to disable these settings and go back to the older, outdated, less secure legacy settings just to get Acronis True Image to work properly??

Secure Boot is a security measure that can be disabled without effect on UEFI.  Disabling Secure Boot will not revert you to a legacy bios or legacy boot.

The Acronis loader must be able to access as you put it root level or low level disk access in order to create a complete full disk backup that when restored will boot.  To gain that access Secure Boot must be disabled during a recovery process so that the computer can enter a non Windows environment to perform the recovery.

Again, such a recovery of a Windows System OS disk should be performed using the user created Recovery Media.

I am able to boot TI 2016 Recovery media in UEFI mode with Secure Boot enabled. There are two types of Recovery media available with TI. One is based on the Linux operationg system. This is the default media used. The other is based on Microsoft's WinPE. I am able to boot both on my Asus P8Z77 motherboard in UEFI mode with Secure Boot enabled.

The default Linux recovery media has its limitations. It does not support the hardware on all computers. You should test it as follows:

1. Try booting it in UEFI mode with Secure Boot enabled. If it boots and runs TI 2016, make sure it can see the hard drives you are using for backup and restore operations. If it does not, you need to use the WinPE Recovery media.

2. If it does not boot in UEFI mode with Secure Boot enabled, try disabling Secure Boot. If it does boot, you have found the Secure Boot on your computer is not allowing a non-Windows operating system to boot. You will need to use the WinPE Recovery media or disable Secure Boot to use the Linux Recovery Media.

3. If it does not boot in UEFI mode with Secure Boot disabled, you have found the Linux system does not support the hardware on your computer. You will need to use the WinPE Recovery media. When this is the case, performing recovery operations from within Windows that require a reboot will not work for you. When the reboot happens, the Linux Recovery system attemps to start. If it does not start, the recovery can't be performed. Again, you will need to perform recovery operation with the WinPE Recovery media

Thanks, I appreciate the help.
