Hello All,
I created a Windows 7 x64 based WinPE image with basic drivers for SSD. This WinPE image is primarily used to capture/deploy Windows 7 image on a monthly basis. I have DOS commands in startnet.cmd to automate this process. When booting from USB flash drive, the script reads drive letter from "PEBootRamdiskSourceDrive" registry value in HKLM\System\CurrentControlSet\Control.
This has been working fine on existing USB flash drives - both USB 2.0 and 3.0. I bought couple Kingston DTR3.0 G2 64GB flash drives recently... when I boot to these flash drive, the registry value with drive letter in PEBootRamdiskSourceDrive is not seen. Registry value in PEBootType says Ramdisk:SourceUnidentified. I am puzzled with this behavior and looking for clues.
Appreciate any tips / pointers. Thanks!
