Acronis Loader Fatal Error: Boot drive (partition) not found.

I am running Windows 10 (slowly) on an Inspiron Mini 1018 laptop.

When booting from a USB recovery drive, it gets the error:

Acronis Loader Fatal Error: Boot drive (partition) not found.

The BIOS SATA is set to AHCI, if it matters.  It does not support UEFI.

Any suggestions?

Walt, there have been several posts in the forums for similar problems that give the same error message.

See 26566: Acronis Loader fatal error: Boot drive (partition) not found 
and  55955: Starting Acronis Loader...Acronis Loader fatal error: boot drive partition not found

Both of these posts are quite old and refer to much older versions of ATIH than your 2015 version, but the principle advice offered is still sound, i.e. try changing the SATA to ATA instead of AHCI (just for the boot media), and try with the WindowsPE version of the Rescue Media.

If you are intending to try to clone your drive from the USB recovery drive, then see KB document: 56634: Acronis True Image 2016: Cloning Disks to ensure you are following the correct process to do so.  The KB applies equally to 2015 as to 2016.

Steve, thanks for your suggestions.

Short story: I eventually managed to create a WinPE recovery medium on a USB flash drive and was able to back up the machine.

Long story: Changing the SATA to ATA didn't help, and produced some scary error messages trying to boot Windows.

Eventually I was able to get ATI 2015 to try to create a WinPE USB recovery flash drive on my main Windows 10 PC.  (When ATI asks to install the Windows ADK, don't install the Windows 10 version, install the one it links to, which is for Windows 8.1.)

The first recovery drive wouldn't boot.  After that, ATI repeatedly failed creating another recovery drive.  I tried it over and over with several different USB drives in different ports.  After a number of failures, it created another recovery drive.  That one booted the laptop and I was able to do the backup.

Thanks for your help.

More details that might be helpful to someone else:

I created a WinPE recovery medium on a number of different USB flash drives.  The only one that would boot on either my main PC or the netbook was a Kingston 8GB DataTraveler G4 USB 3.0.  Since I wanted a backup copy, I wound up ordering another 8GB DataTraveler.  It works fine, just like the first one.  But I haven't been able to get any other flash drive recovery medium to boot.

I am having similar issues when booting from the supplied True Image 2016 disc (see attached photo). We buy copies of this for all our machines to backup known good configurations. I have so far been booting from a USB version of True Image 2015 while we find a solution.

John, welcome to these user forums.

When using the Acronis rescue media (on CD/DVD or USB stick) you should ensure that you are using the latest build version for the release of ATIH you are using.  Some systems will boot fine from CD/DVD whereas others require the use of a USB stick.

If you have been using the CD that was originally supplied when you purchased Acronis, then this is very likely to be a much older build.  Please sign in to your Acronis account on the web and providing you have registered your Acronis serial number(s) then you will be able to download the latest build version for ATIH 2016 which is now #6581 (as of a couple of days ago).  This is in the form of an ISO file which should be burnt to optical media, or else can be burnt to USB using a free utility such as ISO to USB.  You can also create this rescue media on either media directly from within the ATIH 2016 GUI using the Rescue Media Builder application.

That would be my recommendation - and use a USB flash drive if you can.  It helps eliminate things like bad CD/DVD's from the manufacturer, bad disc burns, etc.  It is usually faster to boot too.  

And now to make things clear as mud...

Most systems that support CSM/Legacy mode and UEFI mode (that are configured correctly in the bios), can boot with an Acronis USB recovery flash drive to UEFI mode, whereas sometimes systems can only boot CD/DVD in legacy mode. You should always try to boot your recovery media to match how the OS was originally insalled when an image was taken - how you boot the recovery media will determine the parition layout of the recovered disk (booting legacy creates a legacy/MBR disk type and booting the recovery media in UEFI mode results in a UEFI/GPT disk type).  You can never go from UEFI/GPT to Legacy (well, you can, but it won't boot).  You can sometimes go from legacy to UEFI.  But to keep things simple and straightforward, keep things the same.
