No bootable device found issue and battery replacement issue

Hello and good evening I’m am in need of a lot of help. A few weeks back, when I tried to update my dell inspiron laptop, it was stuck in a loop of showing the dell logo. But on the next day, a few minutes after I turned on my laptop it showed a screen where it said there was no bootable device found as shown in the image below. Also I am dealing with another issue where my laptop heats up very quickly and I am in need of a battery replacement, since my dell laptop is saying my battery is in poor condition. Unfortunately, my basic dell warranty plan expired I think a year ago and I am out-of-warranty, so I’m not entirely sure if I should send my laptop to dell for repair. Are there any good alternatives, such as a good repair shop that can repair a dell inspiron? Or do I HAVE to send my Dell? Any help would be greatly appreciated!

Dell model: Dell Inspiron 7306 2n1
