Hard Error ntdll.dll

[varun037]

Hi..

I am getting an odd error

STOP: C0000221 Unknown Hard Error

\SystemRoot\System32\ntdll.dll

I have noticed one issue - I get this error only when i use option to optimize the dvd.

My original dvd is 4.97 gbs and optimized size is 4.31 gbs. I have used poweriso,

ultroiso and easyboot. If i dont use optimization i dont get this error.

I am trying to make a multiboot dvd which included

WinXPE (SP2)

WinXP Professional Edition (SP3)

Win2000 Professional
