I have a backup of my entire softmod/og xbox hdd that i did when i did the softmod on it. It's in a .iso file. It contains everything on it from c,d,f partitions and has the backup of the eeprom in it. My evolutionx dash, skins, few programs like dvdtoxbox. I softmoded it with the sid 5.0 and game exploit, had Evolutionx dash. The hdd i upgraded to 360gb hdd. I must have made the backup before i started burning games to the drive. I have no clue what i did with the original drive, i probably chucked it as i had the backup.
How do i take this backup .iso and put it on a new hdd to put in my xbox as there doesn't seem to be any tutorials on doing this specifically?

So bit of background;
I'm not a noob to softmodding og xbox's, but last time i did a softmod was before the rocky5 method existed.
My xbox is stuck on and will only boot to the xbox dash after an error 21. This happened after i accidentally clicked on connect to xbox live on call of duty and it updateed. I read somewhere there are 2 files you need to delete once a game is copied to hd in order to prevent this, but i can't remember what they are? Any help there would be good to.

I cannot ftp into the hdd anymore as ftp won't find the console. Also i tried burning the Hexen2018 to disk, but that won't boot, and have since learned you need softmod dash for it to boot so no luck there.
Next i tried xboxhdm23usb beta3 as i have a few spare external 2.5 dives in external enclosures. Only thing i did here was put the eeprom in root folder and tried basic build as is first to see if it will work. But again no luck. It finds the hdd's, but keeps coming up with -h and -d errors  when i choose option 5 or xboxhd program.


Can anyone help?

I just wanted to say hi to everyone. It has been a while since I modded my OG Xbox, but with the HDMI solutions coming, I felt the need to update the console. My plans are to replace the old IDE drive with a larger SATA one and possibly look into what the best HD bios is that I can get on my Xecuter chip. It has been a while since I originally set this up, but I am definitely glad to see this site and all the info here. 

New splash screen. Several colors.
