Win 10 Boot Manager Corrupted after Acronis Recovery -- can't automatically boot into the primary C: drive
I have a Dell XPS 8930 (32GB Ram) running Win 10 Pro. I recently had to use my Acronis True Image 2019 recovery off of a USB port to recover my primary C: partition on my 256GB SSD drive. The recovery process went well, however, my BIOS now boots into a Windows repair utility that cannot find an issue and then only let's me reboots back into that same repair process. It appears that it is trying to reboot using the other attached hard disk drive where I had my back-up files located and not to the primary C: drive. Using F12 I can interrupt the process and select my primary disk and then it boots fine into Windows. My BIOS uses the UEFI and boot manager. I need to redirect the BIOS to the primary C: drive. I've read where some suggest changing the BIOS setting from the current protected UEFI boot mode to the legacy mode. Frankly, I am a bit hesitant to mess too much with BIOS and end up really messing things up (although I suppose I can always pull the CMOS battery to reset it). Has anyone else encountered this issue and can advise me how to get my computer to automatically boot back into the C: drive?? Thanks!

THANK YOU for your reply! I tried both options. In the BIOS (using F2) I cannot find any sequence setting in the Boot options that allows me to permanently select one of (apparently) 2 instances of Boot Manager that is on my system (see below). BCD says it fixed it, but I still have the same issue (boots into a Windows Automatic Repair Utility that gives me options but doesn't fix anything). I even turned Secure Boot off -- still no luck. Apparently I have two instances of Windows Boot Manager. When I use F12 I get a selection menu (but can't dset anything permanent):
UEFI OPTIONS
Windows Boot Manager
Onboard NIC (IPV4)
Onboard NIC (IPV6)
HDD1 - Windows Boot Manager (Toshiba 256GB)
If I select the HDD1 option (where my real OS is) it boots into Windows 10 fine. The others don't do anything (I even tried the NIC IPV4 option and noting at all happened upon reboot -- had to pull the CMOS battery to get things back again.)
As you can tell, I am fairly good at this stuff, but certainly no expert, especially when it comes to the BIOS. Any help / advice to get my system automatically booting back into Windows on my C: (HDD1) drive is most appreciated!

Look at the EasyBCD image in my previous post, and try taking the option to 'Change boot drive' then click on 'Perform Action' which will then give you a new pop-up windows where you can select the correct boot drive. The list will have an * against the current boot drive.

Thanks, Steve! Must not be my day. Here's what I got when I pointed it out the C: drive. Interestingly, Windows Computer Management reports the C: drive as being a primary partition. I've included a screen shot of my drives. Wondering if the the 500MB System partition on Disk 1 sitting before the OS C: drive might be causing issues? Disk 0 is my 2TB HDD data drive. It also seems to have a system partition on it. Again, any thoughts appreciated!
Thoughts?

Sorry but not seeing any images in your post. You need to click on the 3rd icon from the right on the bottom row of icons for the forum editor (Mountains with black sun in top left corner).
The boot partition on your OS drive should be the EFI System partition where the BCD store is normally kept.

Sorry Steve -- hope this works:

A couple of thoughts here:
Can you disconnect your Disk 0 data drive then retry booting the computer?
Given that Disk 1 is your OS drive, if the computer boots correctly without Disk 0 connected, then I would recommend removing the duplicate partitions on Disk 0 shown in your Disk Management image, i.e. 500MB EFI, 460MB, 11.74GB & 1.06GB partitions, which are being picked up by the BIOS as boot partitions.
Ideally, Disk 1 should be moved to the port used by Disk 0 and the reverse for Disk 0, as your OS drive should be shown as Disk 0 rather than 1.
Note: you may need to use a partition tool such as the free MiniTool Partition Wizard to remove the hidden / system partitions from the data drive (disk 0).

Thanks again, Steve. As this is somewhat involved, I'll have to try it on the weekend when I have more time to take my computer apart to see if this works. Appreciate the suggestions -- I'll get back as soon as I can.

Issue solved! I found and downloaded EasyUEFI (you can Google it)-- there is a free trial period. With it I was able to create a new Boot manager EFI file on the disk containing my OS. Then I simply moved it first in the boot order (all within Windows), rebooted and the issue is solved. EasyUEFI is a great product -- the licensed copy runs $30. I was able to get this done quickly but would be a good investment for long term UEFI maintenance.
Thanks again Steve for your advice!
