Solved! BIOS not showing any boot menu

[anandeshsharma]

I've HP245 g5 laptop yesterday I've converted my hdd's partition scheme to GPT. And after that also it was working fine but today when I tried to boot my laptop it just show "3f0" error and says "install the os". I's unable to boot and also when I tried to boot from a bootable pendrive it is not showing anything in boot device menu. I attempted almost all possible solution from the internet.

What I've tried already:
1. Changed BIOS mode to legacy and disabled secure boot
2. Removed CMOS battery and installed it after voltage is drained
3. Reset the BIOS settings to defaults
4. Performed a hard BIOS reset

My HDD is working as I've checked it on my another laptop. But it shows some bad sectors. Coming to the point, the main issue is with laptop.

My laptop specs:
Processor: amd APU a6 7310
HDD: hgst
Ram: 8 gb
BIOS version: f.31

You are better to contact HP to order the Windows 10 Recovery Disc.
