An unexpected I/O error has occured during boot

[Sree_hari_nair]

When the issue started: My laptop has a dead battery so it only turns on when connected to wall outlet. while using the laptop power went. We have home UPS but there seems to be a slight delay when UPS takes over (lights blink when power goes and ups takes over) and laptop turned off.

Now when i turn on the laptop i get preparing automatic repair with HP logo and then blue screen with error - there is a problem with a device connected.

I tried startup repair but it just comes back to blue screen.

Tried to reinstall windows but it shows the same error.

Tried to swap hardisk and install windows but same error.

Any help will be appreciated

Thank you

Sorry but for security reasons we advise against downloading from or connecting to unknown links.

What is the brand and model name or number of the computer.

What do any Windows Stop Codes say.
