IPXE :: Windows 10 iSCSI disk installation, second stage fails (error 0xc0000428)

[NiKiZe]

So the part that actually gives us information is "digital signature of a file couldn't be verified" there probably is an UPPER_CASE_ERROR as well?
How did you install the nic drivers?
have you worked thru all already existing threads about iSCSI with windows 10 that are on the forum?

To even have a chance of getting this to work, I would use clean Microsoft ISO provided winpe, without mods, also use the drivers that comes with windows, without adding your own, since that does give these kind of issues a lot it seems. But then again, you probably will get other BSoDs instead as discussed in other threads.
