How to remove the back cover of HP Pavilion All-in-One - 24-xa0057c to replace the hard drive

[zhijiu1]

I have to pull out the hard drive of my HP Pavilion All-in-One - 24-xa0057c to backup the data since the computer won't start and I have to use a recovery flash drive to reinstall the OS, which will erase all my personal files in it. But when I look at the back of the All-In-One PC, I only find one screw and a tinny hole. I have no idea how could I remove the back cover to access the hard drive.

I tried to google search to see if somebody has any idea about it. But I was not so luck to get answer. 

Please help!

It's all there in the manual

"use a recovery flash drive to reinstall the OS, which will erase all my personal files in it."

Not necessarily your only option.      Mount the old drive in a Caddy.

If in doubt please ask.

This First part only works when a valid Recovery Partition is enabled.

If it displays an error message then move onto the Second part,
OR if you have data you wish to try and save using the XCOPY command.
Then create your own Repair/Recovery/Rebuild/Re-install media or buy a set from HP.

Turn off the computer.

Disconnect all connected devices and cables, Media Drives, USB drives, printers, & faxes.
Remove media from internal drives, and remove any recently added internal hardware.
Do not disconnect the monitor, keyboard, mouse, or power cord.

Turn on the computer and repeatedly press the F11 key, about once every second,
until the Choose an option screen is displayed, and then continue.

On the Choose an Option screen, click Troubleshoot, and work your way through the screens.

Second Part:-
This may require another PC. Find and Download your .iso from…
 W10 should activate automagically from the embedded licence key.
https://www.microsoft.com/en-us/software-download/windows10

Expand/Extract/Burn the iso Image onto a DVD/USB as needed.
Microsoft’s Creator Tool will make the required DVD or USB.

Even though it has NO actual HP software/drivers included, you may be able to
XCOPY the C:\Users\* area onto a ‘large’ USB stick, via the Command Prompt.

You’ll need to try various drive letters; D:..-..Z: until it’s matched - could be G; mine’s S:

C:\>XCOPY C:\Users\* S:\ /e /i /h (then files like those 3 listed below get copied over)

C:\Users\desktop.ini
C:\Users\All Users\agent.1509128044.bdinstall.bin
C:\Users\All Users\HP Deskjet 2540 series\Help\flash\zoom.swf

Then you can try System Recovery Options / Advanced Options shown in the screenshots.
NB: - W10 Begin with the Automatic Repair, then Startup Settings etc.

From either the C:\ or the X:\ prompt try the following

cd boot
bootrec /FixMBR
bootrec /FixBoot
bootrec /RebuildBCD
