Hi I have an older Dell studio laptop I can't get to boot to anything. It lost power and when I turned it on it started the Dell splash screen and loaded but instead of booting windows it just shows a blinking cursor. I made a bootable windows 10 repair thumb drive to repair the MBR but it won't boot to that either. I tried the original install disc (it came with Vista) but that wouldn't boot. I tried an Ubuntu thumb drive same result. I can access the bios, Dell version A04, and I did CMOS reset but nothing changes. All I can think is the mobo is bricked any ideas?
