Inspiron 13, No bootable device found

Guys,

Last year, I decided to splurge on a new laptop ahhh my Dell is a beauty! Last week, I turned it on and it said,"SupportAssist is running a scan to detect potential hardware problems." I really didn't think anything of it but then I got the following message."No bootable device found.". For days I have researched to find a solution but I only found outdated post. I feel like I've tried everything and can not solve the issue maybe I am doing something wrong? I have been changing my my boot mode multiple times. When I change it to UEFI I get the following message, "Hardware scan complete with no issues. No bootable device found! Possible causes could be a corrupt OS image or a boot device is not enabled for BIOS Set up". When I change it to Legacy it says, "Hardware scan complete with no issues."Then when I restart it....it goes on a constant loop of, "No bootable device found please press a key...". I have also run the diagnostics and it says everything in my system is fine. I don't think it's a virus because I use my Kaspersky religiously lol. I also found recent post on here where people where dealing with the same issue with the Inspiron models.
