    The one entry I don't recognize is the:

    integrityserives Enabled

    But it is just Win 8.1, so I assume all references to Win 10 are gone... not much I can do.

    If you were to do a bcdedit /enum all it might show the prior Win 10 option but you may have gone beyond that.

    Could be the Security chip ie TPM (Trusted Platform Module) perhaps that's why there is a issue at boot ?

    The Manual might tell us if there is a TPM chip

    The computer is a Samsumg ATIV Book 2 (270E5G/270E5J). I should have informed this from the beginning, my bad.

    I tried to translate the output of bcdedit /enum all. Probably it is not exactly as it would be in the english version of Windows.

    Using the MiniTool Partition Wizard as suggest, I explored the EFI partition and found the file now set in bcdedit in the same path.

    Saltgrass, I have an Windows 10 DVD and my notebook is activated. But, before having problems to boot into Windows, I could not select in BIOS to boot from DVD/USB (actually trying to fix this is how I screwed up the boot). If the Windows boot is fixed now, I still need to fix that too.

    And should I try the bcdboot c:\Windows command?

    BCDBoot Command-Line Options

    Repair the system partition. If the system partition has been corrupted, you can use BCDBoot to recreate the system partition files by using new copies of these files from the Windows partition.

    Set up or repair the boot menu on a dual-boot PC. If you've installed more than one copy of Windows on a PC, you can use BCDBoot to add or repair the boot menu.
    Run the following commands at the command prompt (as administrator).

    diskpart
    list volume (Note the volume letter where the Windows OS is installed)
    exit

    bcdboot X:\windows (Replace "X" with the volume letter of the Windows OS partition)

    The picture shows how to fix (bcdboot e:\windows) the Windows 7 startup issue on a dual-boot system.

    Yes.

    Repair the system partition. If the system partition has been corrupted, you can use BCDBoot to recreate the system partition files by using new copies of these files from the Windows partition.

    bcdboot c:\windows

    UEFI: BCDBoot copies the boot files from the Windows partition to the EFI System partition and creates the BCD store in the same partition.

    Legacy BIOS: BCDBoot copies the boot files from the Windows partition to the active partition on the primary hard drive and creates the BCD store in the same partition.

    Have you ever set up TPM on this Laptop ?

    What is a TPM, and Why Does Windows Need One For Disk Encryption?

    Windows Trusted Platform Module Management Step-by-Step Guide


    The manual I found suggests that CD/DVD is the default option for boot device for the Computer but can be changed to USB etc in the Boot Options, but I guess you don't see that? It does say to turn off Fastboot , if trying to use DOS CD's however my guess is they mean if it is MBR based and not UEFI , so best to disable it anyway and transfer the Win10 ISO Files after mounting it , to a Fat32 formatted USB Drive which should be set Active as well with MTPW.

    Kbird, I never touched TPM.

    Initially (since I bought the laptop) I was able to boot from DVD, USB, other SATA devices, etc.. There was a bunch of options in boot menu. I even had installed Windows 10 from a DVD, since the update from Windows 8 was buggy.
    The problem of not being able to boot from other thing than Windows Boot Manager started after I removed linux (for this problem might be better to go in a linux specific forum).

    I guess I will try to reboot the system tomorrow and hope it works after changing the path with bcdedit and using the bcdboot as suggested by Feather. If it works, then I will search how to make it bootable from other devices again.

    You all have been very helpful so far, thanks a lot.

    I will post an update tomorrow.

    No, the BCD store does look correct for a UEFI Boot. You could try it, it appears you have nothing to loose.

    I am not clear on your situation with booting to the DVD. A DVD has two versions, if the DVD is loaded prior to starting the boot sequence, there should be in the Boot Device Menu , a Basic DVD and a UEFI version. If you were running secure boot, it should only be looking for the UEFI version. If you cannot see the UEFI version of the DVD you may have the bios set to boot Legacy.

    But you need to have the CSM disabled and secure boot enabled to see only the UEFI version of install media. But every Bios seems to be different as to how it presents options, so hard to say for sure. And I do not know what the IntegrityServices option in the BCD store does or how it might be effecting your boot.

    I also do not remember seeing so many Firmware Applications in the BCD store. Mine are normally limited to bootable devices only, such as the DVD but you seem to show Recovery options and others. Maybe these are tied to the IntegrityServices entry. Your EFI partition is the second partition on the primary drive?

    How can I check this?

    Regarding Secureboot, CSM and Legacy Mode options, I have tryeid all combinations, none worked.

    Just now I remembered something. When using the Recovery, the utility was naming the partition where I had linux installed as D:\ (which was the DVD drive name in the OS). Could it mean something?

    It will tell you in MTPW under the TYPE column.... post a pic if needed of the view.

    Pics of your Bios Options for CSM etc may help Saltgrass or I pinpoint an issue , you may also need to delete all the keys in the SecureBoot area , it usually has an option to return to factory state or something similar.


    If the Computer was already registered with Win10 and you don't need the Win8 Recovery Partition any more , I would just Wipe the HDD with HDD Low Leveller Formatter , and Boot into a win 10 UEFI install DVD or USB , and forget about all these issues.

    If it has a SSD then doing a Secure Erase will be quicker than a LL Format and better for a SSD.
