Vostro 5480 BIOS update crashed, now bootloops
I recently tried to update the BIOS of my Vostro 5480, but the update froze in the end. I waited 1 hour but Windows was still frozen, so I decided to turn off by holding the power button.
Now I can't boot anything else, as it will always goes to the BIOS screen with the message below, it waits 5 seconds and then reboots itself.
Unfortunately, it's not under warranty anymore.
I searched Google for solutions, but none helped me. I got the latest BIOS file (can't find old ones), and tried putting the files inside a flash drive (.exe, .hdr and .rom files) with some random and suggested names, but I couldn't get it right.
Is there anything else that I can try?
Thank you in advance
