My notebook Pavilion 15 p045tx crashed, showing error boot device not found

[azizzaamir]

After messing up with partitions using third party software, my laptop ended up in boot failure. I need to restore my original genuine OS that came with it. And also hard drive contains heaps of data which I don't want to lose. Please advice me! Thanks in advance...!

Hi,


Specs: https://support.hp.com/in-en/document/c04334489

Your laptop came with Windows 8.1 64 bit from factory

Did you upgrade to Windows 10 Home 64 bit previously?

Please perform extensive hard drive and memory tests from System Diagnostics UEFI by tapping F2 or ESC key as soon as you power on laptop before proceeding.

If tests PASSED, you can clean install Windows 10 Home 64 bit using Microsoft windows media creation tool by creating UEFI bootable installation USB:

Windows will be automatically activated after installation while connected to internet

Additional drivers from here:

Alternatively you can buy HP Recovery USB directly from HP support specific for your model with a cost of ~$60

There are 2 main methods to salvage data from HDD before doing clean install:
1) Create LiveCD from another computer. Boot from this disc in your laptop, then copy the files from failed HDD to another external hard drive connected to notebook.

2) Take out the failed hard drive out. Connect it to another computer using SATA to USB adapter. Use Windows explorer to copy the files you need from HDD to another external hard drive.

Chances of recovery is more for 1st method.

Hi, thanks for quick reply. After manually installing win 10 64-bit through bootable USB, do I need to install all the drivers or few from the the link you provided.

[visruth]

Most of it will be automatically installed by Windows updates

But in case there is missing drivers (yellow exclamation marks) in Device Manager, you can get the drivers from that link

Thanks a lot mate! I installed downloaded win 10.iso, made bootable USB, installed OS, installed drivers, installed EaseUS PARTITION recovery tool, and voila! My lost data partition reappeared..! Thanks again mate!
