We've been successful in the past deploying Windows XP, following guidelines in the Hardware Independant Imaging Toolkit. Recently we've tried adding some new Lenovo T500 and SL500 laptops and we're having a lot of problems.
We can boot successfully with WinPE and our OSD script seems to run OK. The image deployment task is completed with a result of success. When the target machine reboots it goes through POST and then just freezes with a completely blank screen. If I reboot back into Win-PE I can see that our customized SYSPREP.INF file has been copied in to the C: drive. Our driver library is also copied in. If I boot back to the C: drive, interupt the Windows XP boot sequence (F8), and select "Safe Mode" the system seems to hang when loading "\WINDOWS\System32\DRIVERS\AGRSM.SYS". I think this is a driver file for the laptop's built in modem.
Any idea why these laptops won't reboot and run SYSPREP?
