How to fix boot device not found – hard disk (3f0) error when booting your computer or laptop. The issue can be that the system is looking to another boot device like a usb key or cd instead of your hard drive (fix in bios boot options). Hard Disk (3f0) error code on boot can be from a dead or dying hard drive. This boot error could mean that your bios option are set to legacy and not secure boot or UEFI boot.

My son spilled water on my laptop. I walked into the kitchen and there was the laptop with that error sitting in a puddle of water while my two year old splashed in the water :/ I have it turned off and set it out to dry… I am praying my computer isn't dead. Any advice or help would be much appreciated.

Thanks. I unplugged the mouse and I was ready to go. You saved my laptop

Mc Santy says:

the hard drive passed. I went to boot options changed the legacy support, which in turn changed the secure boot. saved that and now it just says boot devices not found. I know I have to set it to factory setting for Windows 7, but I don't know how to do that without a CD and from the boot device not found screen

It worked, thank you so much

Anderson says:

Nope everything didn’t work. Tried 5 different videos. 7 different websites. Even tried fixing it my self. I’ve spent 3 hours trying to get this thing working again, and I’ve come to a conclusion that my hard drive or port is basically screwed. This has been the most helpful so far but yeah. Guess I can’t fix this one by my self.

Man windows is de le te and i can,t connect m'y 💻

Bean Burrito says:

Wait, so if the Hard Drive Check says it doesn’t detect a hard drive, I have to determine whether or not it’s the Hard Drive itself or the cable connecting it to the computer that’s dead? How can I tell?


Spray some Febreze on that jawn .. Come back 10 minutes later it should be good
