Dell Inspiron is UEFI based and it took me a while to figure out how to ghost it.
1. YOu need find a image support uefi with Ghost, I cant provide you this. You need figure it out yourself. I am only focusing on Dell Boot area.
2. Go to BIOS and go to BOOT. Disable Secure BOOT. Then ADD a boot option.In my case I type in USB. GO to the boot option select the hardare -> USB...
It will ask you to type in the INPUT FILE NAME. Look at your image. Find the EFI folder. and Point it to the boot efi file under it. In my case, it is:
\LMT\EFI\boot\bootia32.efi for 32boot.
\LMT\EFI\boot\bootx64.efi for 64bit.
Press F10 to save and exit. Now restart the computer and press F12, then select USB. It works for me!
3. Restore the system is exactly same on another Dell computer. However after restore, you need use a clean WINPE5.1 image to restore boot information with both command.
Start with WINPE5.1 Image, in my case I have a network image from WDS to do this. IF you are not sure how to do it, go search WINPE on my blog and you can find it.
BCDBOOT C:\WINDOWS
BCDEDIT /TIMEOUT 0
This will restore your netbook like factory default, cheers!
