Boot Device not found

[ChariseJones1]

I replaced the battery on my laptop and now it says that error message and tells me hard disk not found. Not sure how to fix it

BOOT Device not found error is commonly seen during the process of booting operating system. As it indicates, Windows OS can't find a bootable device to boot from, usually, it can be an internal hard drive, external usb drive, optical CD/DVD ROM drive and network adapter.

You should take prompt measures to figure out what causes the bootable drive missing. Here in the following, you may use it as reference.

• Wrong boot order in the BIOS
• Hard disk connection problem
• System files or boot files unknowingly damaged
• Master Boot Record (MBR) or boot sector is damaged on the bootable disk
• Other outside attacks, such as third-party system protected application, virus, malware, etc.

Or you may reference these articles to see if there's a way that works to you case.

Hello @ChariseJones1

Thank you for posting in the HP Support Community.

Try reseating the hard disk drive as shown here in this official video >> https://www.youtube.com/watch?v=_EdSDosnLnk

Let me know if it is still not detected after that.

Am I correct to assume you performed hardware diagnostics (F2) and it is there where it shows no hard disk drive present ?
