    Dual-Boot 7 & 8 Winload.efi 428 Error

    Hi all,

    I've read everything I could find on this forum and tried all the fixes w/o success. Here's the rundown:
    I have a Win7 machine that runs fine. Created a second partition C: for dual-booting Win 8.1. After a clean install, I got the following error when trying to boot into 7:

    Status 0xC0000428
    The digital signature for this file could not be verified

    Win8 boots fine.

    Tired all the usual stuff w/o success (a partial list):

    • Windows repair (it doesn't find any problems)
    • bootrec /fixmbr
    • bootrec /fixboot
    • bootrec /rebuildBCD
    • bcdedit.exc /store c:\windows\system32\winload.efi /set loadoptions ddisable_integrity_check
    • bcdedit.exe /set testing on
    • Tried EasyBCD to reassign \windows\system32\winload.efi to another version/copy located in \windows\system32\boot.
    • I've tired reassigning the bootloader paths using EasyBCD and from a Windows recovery command prompt ("bcdedit.exe /set {f1368352-7a2a-11e3-934f-88b9245c9fb7} path \Windows\system32\boot\winload.efi).
    • I've copied both winload.efi and .exe from another folder with the same results and unpacked the files from my Win7 DVD and using them. Same error message.

    The funny thing is, when I do this last "fix" I get exactly the same error.

    But things get even weirder. I tried restoring an image made of my Win7 OS (made before attempting dual-boot) back to the first partition, alongside the Win8 partition, thinking that this might fix my Win7 loading problem. What happened was that Win7 loaded now but not Win8, which returned the very same error message I got before with Win7.

    Also, this problem occurs whether I'm booting from Win7 or Win8's boot manager.
    I've been at this for 4 solid days, trying everything I can find w/o, of course, success.

    I'm booting off of 2 SSD drives in RAID-0

    Here're my drives in Disk Manager:

    I suppose a couple of questions.

    Is the 4 TB drive configured as GPT?

    Was Windows 7 a UEFI install before Windows 8 came along?

    Are you trying to use the Windows 8 Secure Boot mode?

    Could you attach the text file, or zip and attach from the following command in an Administrative command prompt.

    bcdedit /enum all > %userprofile%\Desktop\bcdtext.txt
