Vuong Nguyen Posted June 24, 2008 Share Posted June 24, 2008 I'm getting a BSOD when I try to boot a WinPE 2.0 image using a flat file structure instead of the ramdisk. I only get this BSOD if I boot off of a usb device (flash drive or external dvd drive). If I boot from an internal dvd drive, the exact same WinPE image boots correctly. I basically followed the instructions in the following KB article, except for the parts about applying the hotfix because I'm already using Vista SP1 to generate the WinPE files.http://support.microsoft.com/kb/928570/en-usHas anyone else seen this problem?

Radimus Posted June 25, 2008 Share Posted June 25, 2008 from everything I've seen about this, the issue is due to the OS at some point re-initiallizes the USB bus. When it does that, it looses the USB drive and the data on it. Therefore it cannot read from the disk and tends to Blue Screen.To work around that, they developed the RAM Disk proceedure.

killerb255 Posted July 9, 2008 Share Posted July 9, 2008 If it weren't for that problem (reinitialization of the USB bus), then that would be a nice option for machines that can boot from USB, but have less than 512 MB of RAM.I never tried flat-file from CD, though (of course the entire PE environment would be read-only)...

Atheros Posted July 16, 2008 Share Posted July 16, 2008 you will need to modify/add the following values to your registry. you can only do this when the cd key is not booted. so do it on another machine. open regedit and then load the system.hiv %systemroot%\windows\system32\configmodify the following values in the hiv[HKEY_LOCAL_MACHINE\SYSTEM.SAV\ControlSet001\Control\CriticalDeviceDatabase\*pnp0a03]"Service"="pci""ClassGUID"="{4D36E97D-E325-11CE-BFC1-08002BE10318}" [HKEY_LOCAL_MACHINE\SYSTEM.SAV\ControlSet001\Control\CriticalDeviceDatabase\pci#cc_0c0320]"Service"="usbehci""ClassGUID"="{36FC9E60-C465-11CF-8056-444553540000}"[HKEY_LOCAL_MACHINE\SYSTEM.SAV\ControlSet001\Control\CriticalDeviceDatabase\usb#root_hub20]"Service"="usbhub""ClassGUID"="{36FC9E60-C465-11CF-8056-444553540000}"[HKEY_LOCAL_MACHINE\SYSTEM.SAV\ControlSet001\Control\CriticalDeviceDatabase\usb#class_09]"ClassGUID"="{36FC9E60-C465-11CF-8056-444553540000}""Service"="USBHUB"[HKEY_LOCAL_MACHINE\SYSTEM.SAV\ControlSet001\Control\CriticalDeviceDatabase\usb#class_08]"ClassGUID"="{36FC9E60-C465-11CF-8056-444553540000}""Service"="USBSTOR"[HKEY_LOCAL_MACHINE\SYSTEM.SAV\ControlSet001\Control\CriticalDeviceDatabase\gendisk]"ClassGUID"="{4D36E967-E325-11CE-BFC1-08002BE10318}""Service"="disk"[HKEY_LOCAL_MACHINE\SYSTEM.SAV\ControlSet001\Control\CriticalDeviceDatabase\usbstor#disk]"ClassGUID"="{4D36E967-E325-11CE-BFC1-08002BE10318}""Service"="disk"unload the hive, boot from the usb key and it should boot up fine.the issue you are seeing is that that windows plug and play is kicking in and loading the driver, dropping the usb key. ususlly with the blue screen of 0x0000007B Link to comment Share on other sites More sharing options...

Still getting the 7B stop error on boot. If you have any other suggestions, I would like to try them. Link to comment Share on other sites More sharing options...

Atheros Posted July 18, 2008 Share Posted July 18, 2008 are you sure you did them correctlyhkey_local_machine\"whaterer you loaded the hive as"\ControlSet001\Control\CriticalDeviceDatabase\usbstor#disketcetcyou may not have the drivers in the pe image. even though in winpe theyre normally copied by default. have a look and see.

Based on the registry values that you posted, there was one missing file -USBSTOR.sys. I copied it to the WinPE drivers subfolder from my own Vista workstation's drivers subfolder.However, after doing this, I'm still getting the 7B stop error, so at this point I would probably need a checklist of all of the usb driver files that I should have in the WinPE drivers folder to make sure that I do have all of the necessary driver files in this WinPE image.
