My acer aspire suddenly says "no bootable device" and turns off

[Shadowdeath Ae]

First.. It said hard problem. And then it told me to take some instructions somewhere and put it in a USB drive or a DVD (which i forgot to). And then i restarted it and it wont open and says no bootable device. And turns off on its own.

If anyone knows how to fix this please leave a solution here or please email me

go into your bios to see if your hard drive is seen there.

Those errors and messages were telling you the hard drive is bad and to backup your data. If you ignored those messages, it's very likely the hard drive is not fully dead and needs to be replaced.
