Copy what bits? Using resource hacker or similar program will properly add in the bytes for you. Many resource editors will update the checksum automatically. You can run the program I linked to anyways. It will update the checksum if necessary or tell you that it is already up to date. You don't need a hex editor...

i was thinking about doing the same thing with the animation but i didnt try it becaue you cant replace that my bits at once and not **** up the crc
I dun remember now......it's been awhile since I have messed with any of the animation hacks

I tried the edit using Resource Hacker and once I saved it, the file signature was gone.....

Okay. PE files (EXE, DLL, SYS, etc) have two forms of security. The first is a checksum that every PE file has, although it is only checked on important ones. This is typically updated automatically with the resource editor, or can be done with the utility PEChecksum on my webpage. The second is a digital signature that is only put on code that really needs to be secured, such as winload.exe. This is the one you are probably having a problem with. To 'update' this you would need the original private key used to sign it (which Microsoft isn't going to give you) or you can sign it yourself like I listed before.

So if during the boot it says that the checksum is wrong, use PEChecksum.
If it says the digital signature is wrong, you need to re-sign the file.

I think I was talking about using the hex editor like they said on that site you found for disabling all signature checks. I successfully found all the values I needed to change, but it didn't work and Windows still complained about the file.

Do you have two winloads? Like one osload and one winload? That is what that webpage (the one you linked to before) told you to do. They told you to make two options so you wouldn't brick your computer. Sadly, their method only works for beta and RC Windows 7, not release Windows 7.

You shouldn't need a hex editor for anything unless you are really planning to muck around in Windows binaries. Then I would recommend IDA Pro with Hexrays. It isn't really a hex editor, it is a de-compiler and dis-assembler, allowing to see the code (possibly) that was written to create the file. Microsoft has however heavily obfuscated their code, and especially winload.exe. That's the reason no one has cracked the release version of Windows yet.

From the Windows SDK you need: MakeCert, pvk2pfx, and SignTool. I also recommend grabbing CertMgr.exe while you are at it. The whole SDK is awfully big for just signing.
