I figured out how to boot from recovery disc with UEFI BIOS

Thread solved

I’ve been using Acronis True Image since the 2014 version, and here are a few thoughts. If you’re doing a disaster recovery backup, do it when the operating system isn’t running. This ensures that you’ll get all the files since none will be loaded and locked. Either set it up to backup on bootup before the OS starts (I haven’t figured out how to do this with ATI 2019 yet), or boot from a disaster recovery disc. This probably your best bet, since it insures that a recovery is possible. For example, I have two computers, my home built desktop and an HP Pavilion laptop. Both are running Win10 and are running in UEFI. Booting from the ATI 2019 recovery disc was never a problem with the desktop, but an endless frustration with the laptop. I finally figured it out. In addition to having the DVD drive set at the top of the boot drive order, YOU MUST HAVE “Secure Boot” DISABLED IN THE BIOS SETUP. This has been a dearly won lesson that I hope will benefit others.

Albert, welcome to these public User Forums.

Thanks for sharing your thoughts for other users to find.

There should be no problems with creating a full Disk & Partitions backup image from within an active Windows OS using any recent version of ATI as this will capture all locked files etc by using the Microsoft VSS snapshot feature.

With regards to booting from Acronis Rescue Media in UEFI mode and whether Secure Boot should be disabled or not, this really depends on the type of rescue media being used.

If you are using the older, Linux based, rescue media then this can require that Secure Boot is disabled.

If you use the Simple method of creating rescue media in ATI 2019, then this will attempt to create Windows PE rescue media using files found in the Windows 10 Recovery Environment, and which do not require Secure Boot to be disabled, as you are in effect booting another copy of Windows 10 (similar to that used to install Windows).

Note: it is possible that your HP Pavilion laptop is not running the latest version of BIOS and this can contribute to problems in this area.  I would recommend checking on the HP Support website to see if there are any later BIOS versions for your laptop.

See the following reference documents.

KB 61632: Acronis True Image 2019: how to create bootable media - for details of the 3 different types of rescue media.  Default Simple mode uses Windows Recovery Environment, then Advanced mode offers the older Linux media or Windows PE (using the Windows ADK).

WOW! Thanks for the prompt and thorough response Steve. You sound like the guy that wrote Acronis T.I.

Being able to do a full backup from within Windows is something Acronis should make clear and advertise more. I don’t remember being able to do full backup from within the OS since DOS 3.3.  This is a biggie. It looks like my backups from the boot disc are about 4 Gig bigger than from within Windows though. Maybe its skipping temp and cache files?

My boot discs were created using the simple method.

HP just released a new version of the BIOS last month. I was running Insyde F.14, which came out just after the Spectre/Meltdown exploit panic started. So I upgraded to F.20 (there were no intermediate versions listed). Now I can’t get it to boot from DVD at all. In addition to disabling Secure Boot, I enabled Legacy Support. I think I need to check with HP, I doubt this is an Acronis problem. I’ll probably go back to the older BIOS, since I KNOW I can get a recovery done. It may boot from DVD if the hard drive is dead, but I want to be sure no matter what.

Albert, there are a number of large items that get excluded by default when making backups using the Windows ATI application, these include the system pagefile.sys, hiberfil.sys and swapfile.sys which can add up to many GB's of data, plus the System Volume Information folders where Windows stores Protection / Restore Point data. 

Note: You can set exclusions in the bootable rescue media but this has to be done manually every time you use it, whereas the Windows app remembers the exclusions and applies them each time a backup is made.

I would recommend trying the Acronis Rescue Media when created on a USB stick instead of using a DVD disc.  With many modern computers, it is much simpler & easier to boot from USB media than from CD or DVD, and you should not need to go back to a down-level version of the HP BIOS.  (The only time I tend to use CD or DVD rescue media is on very old computers which don't like booting from USB).

Note 2: The USB stick should be between 2GB up to a maximum of 32GB in size as larger sizes tend not to boot correctly due to Microsoft restrictions.

Victory! Legacy Support disabled, Secure Boot enabled, 1GB Acronis USB boot flash drive works. Many thanks Steve.

Respectfully,
Albert
