no bootable devices recognised in UEFI mode

[Loknath1]

In UEFI mode i get the message "no bootable device found. It is HP Pavilion G6 2132tx

No bootable device showing up in boot manager in UEFI mode,

No dvd drive, no Usb drive , no hdd.
1. I converted windows 10 from mbr to gpt exactly as per process in command prompt, everything successfully done and message came to set boot mode to UEFI in bios. i did that, but now nothing is showing up in boot manager.

2. Used other utilities like hirens boot dvd, but all worked under legacy mode only and yes the HDD has converted to GPT with OS EFI partition.

3. I cant even install windows 10 from dvd in uefi mode as dvd drive is not showing up. not even bootable usb (GB) in GPT mode.

4. Dvd and bootable gpt usb works on dell vostro in uefi mode, so i think there is something wrong with HP uefi software.

the crux is that on my pc everything is ok except for the UEFI mode.

I have the latest bios version available on hp support for this notebook. insyde F2.9

Can anyone here help me out to make devices visible in boot manager under UEFI mode.

Thanks in advance

Thank you for posting on the HP Support Community.

I appreciate your efforts to try and resolve the issue, as No Operating System or No Boot Device. In these cases, reinstalling the OS from media such as DVD or USB fixes the first; rebuilding the boot records using various utilities fixes the second. But any time a laptop simply refuses to turn on, that tend to indicate a serious hardware failure. I would request you to contact our Support and our Support Engineers should be able to sort this out.
