We purchased 50 refurbished desktop computers (OptiPlex 760 and 780) from a dell registered partners.
All the 760 and 780 have the Western Digital with 250 Gb Hard Disk
Hard disk Model No: Western digital WDS2500AAJS
I had installed a Windows 7 on a OptiPlex 760 PC from a windows 7 disc and after installing all the drivers and after successful completion of the OS with all Microsoft updates, I captured the image of this PC from a Paragon Hard disk manger 12 recovery media builder (licenced version) and it successfully captured the image of this working PC on to an external HD Drive.
I then restored this image through the recovery media builder to another PC of the same model. After 30 minutes of going through the restore process, paragon finally says the restore process completed successfully.
When I remove the recovery media from the CD Rom drive and reboot the PC.
I get an error says "No boot device available"
Strike F1 to retry boot
F2 for set up utility
Press F5 to run on-board diagnostics.
When I go to the bios I can see the HD and I tried installing OS on another model dell PC and did the same and I get the same error.
I have no idea as why the Dell PCs is not booting, after successfully reimaging. I have done with the Acer Laptops and desktops the same procedure and it successfully loads the OS after the imaging process.
Any help will be really helpful.
