How did you get your Dell e6510 to boot in UEFI
Dell E6510 with A16 Bios
Hackintosh Yosemite 10.10.2
I installed Ubuntu and the EFI is Fat16 and not Fat32
Edit:
I used Parted Magic to format EFI to Fat32, deleted Windows and Ubuntu partitions and Clover is working in UEFI. Dell E6510 may not read Fat16.
Now reinstall Windows 7 x64
