@Kureebow I’ve had this happen to me before. These are the two cases that I’ve seen:
1 - I captured an image in UEFI and the computer that I was deploying it to was in Legacy mode. I also had the inverse of this, where I captured in Legacy and was trying to deploy to UEFI.
2 (the most common for me) - Some sort of RAID or volume management device is enabled in the UEFI. I only use HP so I don’t know what it would be called on Dell, but on HP there is an option that I have to disable “Configure Storage Controller for VMD”.
