inaccessible required device - boot failure

[tsoifamily]

i have installed OSx10.5.1 with iATKOS v1.0i

 

in the terminal, i typed in "fdisk -e /dev/rdisk0......flag 3......update......write" (my OSx partition number is 3), the process is according to www.freewebs.com/bass-2k7/installingiatkosv10i.htm

 

now i can boot my OSx But fail to boot my vista

 

the screen shows "failure boot because a required device is inaccessible, status 0xc000000f"

 

it also fails to restore as "no restore point" is available when i use my windows recovery (D drive)

 

all my files and documents are in my vista partition, what should i do to tackle this?

 

May all of you please help me! (i hope that i dont need a complete restoration of my vista)

 

Please. thank you
