ERPXE currently uses "tftpboot/er/0-9" to store wim files (3 Custom WIM, 4 ERD, Ghost, Paragon, ShadowProtect).
"bootmgr.exe" has a limitation of 7 letters, for example: "er/a/bt.exe".
You can add /tftpboot/er/a-z folders
Copy "bootmgr.exe" to "er\a\bt.exe" and hex edit it:
Change the "\Boot\BCD" unicode text to "\ER\A\BCD" at: 0x 4F98C
Copy "boot\pxeboot.0" to "er\a\pxeboot.0" and hex edit it:
Change the "bootmgr.exe" to "er\a\bt.exe" at: 0x 5961
Copy "boot\BCD" to "er\a\BCD" and use "BCDEDIT.EXE" to change the osdevice and device entries to use:
"[boot]\ER\A\WinPE.wim,{ramdiskoptions}"
(BCDEDIT.EXE is part of the Microsoft WAIK package)
"bcdedit /store BCD /set {dab9cfa0-d0a1-11dc-bb43-0003ff25b939} device ramdisk=[boot]\er\a\WinPE.wim,{ramdiskoptions}"
"bcdedit /store BCD /set {dab9cfa0-d0a1-11dc-bb43-0003ff25b939} osdevice ramdisk=[boot]\er\a\WinPE.wim,{ramdiskoptions}"
Hex edit BCD file, change location to "er\a\boot.sdi" at: 0x 1910, 0x 21C0, 0x 23F0
Calculate a new checksum on "bt.exe" , we used a tool called "PE Explorer".
"BCD" has an integrity check, to override this run:
"bcdedit -store BCD -set {bootmgr} nointegritychecks Yes"
Add a new option in the menu file to point to the new location of "pxeboot.0":
You can use "er/plugins/wimpe1/wimpe1.menu"
LABEL WPE-CUSTOM MENU LABEL Windows PE 3.0 - ^Custom KERNEL er/a/pxeboot.0
