It sounds like you've done all the hardwork, I use xboxhdm but not quite with the clone.... if you've got your original disk working using Krazie's softmod packs then boot with the original disk to xbmc FTP to your xbox and copy the partitions to folders on your pc representing the partitions (C, E and possibly F if you formatted it) download xboxhdm, read the instructions and use your copied over C, E and possibly F in the appropriate folders also part of the krazie install will have put an eeprom.bin and also a txt file that has all the unlock info - again put those in the right place then run the file to build an iso of xboxhdm turn off your pc, disconnect all disks except the new one you want for your xbox, boot from the xboxhdm dvd - unlock that drive you've already prepared then run xboxhdm and let it format and install the disk, it will give you the option of F and maybe even G if it's a big disk (over 120gb I think) when done lock the disk using the eeprom.bin / txt file (you must have done that before as you actually got that disk to boot) put it in xbox - job done
