Hello all, Please help me with this strange issue. I want to make a unattended boot dvd with windows 2003 standard edition. I have made a unattended CD without the RAID drivers and with winnt.sif , and the other hardware drivers have been included with nlite. Works OK. Now I added the $OEM$ folder to the installation disk with all the software that I want to install after windows installation finishes, but every thing else is the same including the winnt.sif file. Disk structure is the same only $OEM$ is extra ... The only differences are that the second one is bootable DVD and it has the $OEM$ folder inside the disk. RAID drivers are still loaded from floppy. I have tested everything on a virtual machine inside virtualbox and it's working. After everything was ready I made an ISO image of it with nlite , and burned the image on a dvd with nero. When I start installing everything is ok ...I can see the RAID disk, and when windows is copying the files on the new created partition I get this error. Setup cannot copy the file(s): lsi_sas.sys ; lsi_sas.inf ; lsipseud.inf ; lsi_sas.cat ; and some other ... I think that all are for the RAID or something ...and if I skip all then I get blue screen when installation finishes. If you are installing from cd make sure the windows cd is inside the cd-rom drive etc etc ....... My hardware is Sun Fire X4200 M2 server. Thanks in advanced for future posts that can help me with this problem ....
