Problems loading WinPE using WIMBOOT

[Vladimir]

I try loading custom [with drv + add pack] WinPE30 (Win7) and WinPE51(Win8.1) using WIMBOOT.
boot.wim (PE30) - 111 mb original
boot.wim (PE30) - 176 mb custom
boot.wim (PE51) - 264 mb custom
Depending on the hardware platforms the obtain different reslts:

Chipset H77, RAM Size-4Gb
Loading original WinPE30 - OK
Loading custom WinPE30 - ERROR bootmgr.exe: STATUS: 0xc000000D An Unexpected error has occurred
Loading custom WinPE51 - OK

Chipset H77, RAM Size-2Gb
Loading original WinPE30 -OK
Loading custom WinPE30 -OK
Loading custom WinPE51 -OK

Chipset H81, RAM Size -4Gb
Loading original WinPE30 -OK
Loading custom WinPE30- ERROR bootmgr.exe STATUS: 0xc000000D An Unexpected error has occurred
Loading custom WinPE51 - hang on the starting Windows logo.

By the above configurations loading WinPE 30\51 is OK using command -chain.
part of my menu:
