No bootable device
I just purchased a new 5820 tower. When I switched it on for the first time after the system set up it said no bootable device found and forced me to shut down. I read a little and removed everything from the usb ports save for the mouse and keyboard. I powered down and drained the remaining power before restarting and pressed F12 when the dell sign appeared. I then ran the diagnostics and was given the all all clear. However it still can’t find a bootable device. I assume windows was pre installed or should have been. I’m trying to work out how to fix this? I’m nervous to change from legacy to UEFI without knowing what I’m doing. Any help much appreciated as I don’t want to break it but I need to work on it and Dell support isn’t open until tomorrow.
thanks so much

It should be configured as UEFI, secure boot enable by default and boot directly into Windows. Some users may have bought this system without storage (To install their own HDD/SSD) or without Windows (To install their own OS)
Legacy BIOS/MBR boot is mostly for compatibility with older operating systems like Windows 7. Windows 7 can boot from UEFI/GPT but it may need updates for this to work.
If you bought the system with disk and Windows, contact your seller because it should just work. If not, you may have to install Windows yourself. If so, make sure you set your BIOS to UEFI mode and start Windows setup from UEFI mode. This will make sure Windows partitions your disk as GPT.
