I have a laptop that has Windows 7 64 bit Enterprise edition. It is already filled with plenty of Software and drivers.
The laptop (Dell E6220) supports booting through UEFI, but the insatllition was on legacy BIOS.
When I try to change the booting from Legacy to UEFI I get an error message that no boot device was found (the Windows 7 doesn't recognize as bootable). Is there any way I can configure the current install to allow booting from UEFI or do I have to format and reinstall?
