Trepidation,  The precision 5510 has an optional NVMe drive (non-volatile memory express). Windows 7 does not support that technology by default. When you are capturing your image you will need to install a Microsoft hotfix (KB 2990941) which can be found here: [URL] You will also want to make sure that your windows 7 image is built using GPT and not MBR. This will allow you to enable UEFI BIOS for windows 7 though you will be required to keep Legacy option ROMS enabled. Secure boot and windows 7 do not mix!  If your image is already in GPT format you can use DISM to load the hotfix in without having to recapture. If you are unsure how to do that a quick google search of "load updates into offline image using dism" should get you what you need.  As a side note: If you are new to using UEFI, you will want to create your image assist thumbdrives using UEFI as well. That means two things: 1) formatting them using FAT32 and 2) Probably needing to split your Wim files so that you can put them on your thumbdrive. My image is just under 9gb and it is in 3 sections. I hope this is helpful! 
Hello, I've been working with some images I built. After some trial and error I built some stable and rather cooperative images. I went to apply it to a precision 5510 and I can't get it to boot. Is there something unique with the 5510? I've always had issues with the lower end precision mobiles, but I figured this one would be different for some reason. The new process has been rock solid, even on the problem children from the past (xps13 variants).
