Black Screen - Booting SDI via USB

HI all,

I try all the thnig I know to boot my SDI on my USB key but all I got
is one black screen with no error on it after the bios is loaded.

This is my boot.ini... ramdisk is only 1 line:
[boot loader]
timeout=5
default=ramdisk(0)\windows
[operating systems]
ramdisk(0)\windows="USB Image" /fastdetect /
rdpath=multi(0)disk(0)rdisk(0)partition(1)\maple.sdi /
rdimageoffset=4096


This is the info of my SDI with SDIMgr:

So in my USB key I got:
boot.ini
my sdi
ntldr
NTDETECT.com


My USB is NTFS formated with compression on
I do remove the compression on the ntldr and NTDETECT.com

I did also try in FAT32 but failed in a black screen also.

Note: my USB key is a 8GB and the computer can boot with the USB cause
BartPE did boot on it.

Any idea which step I missed or what should I try?

Thanks,

The black screen was resolve by using a new ntldr.

Everything work's find now.

Thanks,
