Boot Device Not Found
The boot device not found prank shows the black BIOS error text every PC owner hopes never to see: no boot device available, please insert a system disk and press enter. The PC hasn't died — it's a browser tab pretending to be a machine with no hard drive.
This is the heaviest of the error pranks, because it doesn't suggest a crash you can reboot out of — it suggests the drive is gone, and with it everything on it. Want something that recovers on restart? The blue screen of death is the softer option. Want the machine to just look off instead? Use the fake shutdown screen.
Hard Disk (3F0)
Press F11 for maximum realism. Tap or press Esc to exit.
Add the prank to their home screen and it runs like a real app — no browser bar, no tabs, no URL, nothing to give it away.
How to use the boot device not found prank
- Tap Launch Full-Screen Prank above (or press F11 once it's running).
- Leave the device where your victim will find it. It'll look completely real.
- When they panic, tap the screen or press Esc to reveal it was a joke.
For laughs only. Nothing here installs, downloads or damages anything — it's all harmless CSS/JS in the browser. It's a staple of April Fools' Day pranks and works any day of the year. Just keep it kind — see what makes a good prank.
Frequently asked questions
Is the PC actually broken?
No. It's a browser page showing BIOS-style text on a black background — the drive, the operating system and every file are untouched. Close the tab and the machine is completely normal.
What does "boot device not found" actually mean?
On a real PC it means the firmware searched the boot order and found no drive with a bootable operating system. Genuine causes are a disconnected or failed drive, a wiped boot sector, or a changed boot order in BIOS. Here it means nothing at all — it's decorative text.
Why does this one scare people more than a blue screen?
Because a BSOD implies a crash you restart out of, while "no boot device" implies the drive itself is gone. One costs you a reboot; the other sounds like it costs you everything on the machine.
How do I set it up?
Open the page on the PC and press F11 for fullscreen. Black BIOS text fills the screen with no browser furniture visible, which is the whole illusion — so don't skip the fullscreen step.
Will it survive a restart?
No, and that's the safety valve. Restarting the machine boots normally straight into Windows, which ends the prank by itself and proves nothing was wrong.
Can I get in trouble for using it?
The page is harmless, but this is one of the easier pranks to take too far. Someone who believes their drive has failed may start a recovery process, buy a replacement, or take the machine to a repair shop. Own up quickly, and don't use it on anyone's work machine.
Does it work on a Mac?
It loads, but Macs don't show BIOS text — a Mac that can't boot shows a folder with a question mark. Use the fake kernel panic for Apple hardware instead.
How do I get out of it?
Press Esc or F11 to leave fullscreen, then close the tab. Nothing needs repairing and no recovery media is involved.
