Acronis UEFI double OS's problem

Thread needs solution

Hello,

I have installed two WIN10 systems on 2 SSD. True Image is installed at one of them and used to do images of both of them. After recovery of 2nd system UEFI boot loeader stopped to recognize that OS. I tried to use all found in web "solutions" - no effect. Acronis support chat - no effect (they suggested to do recovery using pendrive). I had to install OS again from scratch. Question is - what colud I do not to have that problem in the future or how to make UEFI loader  see second system afer recovery (main WIN10 with true image on it recovers very well)? Will separate copy of true imaga on each OS do the job?

Tomasz, welcome to these public User Forums.

Acronis caters for the majority of user systems which are not using dual-boot OS scenarios, so can cause other issues when used on a dual-boot system!

How are you selecting between the 2 copies of Windows 10 in your setup here?

Are you using the UEFI boot device selection menu to select the OS to boot?

Do you have separate EFI system partitions on each SSD holding their individual Windows BCD (boot configuration data)?

Acronis will attempt to make the recovered system 'bootable' at the end of the recovery process which may break some scenarios if the EFI partition & BCD are not where Acronis expects!

Having a copy of ATI on both SSD's would be recommended here along with disconnecting or removing the second SSD in the event of performing a recovery if these are to be maintained as wholly separate copies of Windows 10.

Note: installing ATI in a dual-boot scenario only requires one license as only one copy of ATI will ever be active at any time and the core hardware remains the same apart from the SSD.

Steve, thank you very much for your respond.

I'm using UEFI boot device selection, EFI partiotion on first SSD with WIN10 and ATI. Second SSD has only one partition with another WIN10 system. Screenshot made being logged on the second system. I hope, that configuration lets avoid phisical disconection of drive (which would be extremely uncomfortable). What workflow would you recommend in that config?

 

Tomasz, I would make several suggestions:

First, make an 'Entire PC' backup that includes both SSD's and therefore keeps them fully in sync with each other.  The two SSD's only add up to 1TB in size and I would suspect that they are not running out of free space on the drives.

Next, see Microsoft webpage: BCDEdit Command-Line Options - which you can use to capture a copy of the UEFI Firmware configuration data that is used when you select the boot drive.

bcdedit /enum firmware

The above command (from an Administrator command prompt) will show you the information you are using currently.

If I run this on my own PC (single boot with external USB 3 boot HDD connected), it shows:
