Unable to boot from bootable flashdrive

[Sinandomeng]

Hi all,

I'm now running into a problem after my friend installed Windows 10 64-bit in my machine (HP Pavilion DM4-1265DX). It is very very slow and very unresponsive so I did a research about the laptop I found out that Windows 10 is not supported for this notebook.

From this, I'm now downgrading it to Windows 7 64-bit operating system.

I already have a booted flash drive with Windows 7 on it. The problem now is that the flash drive can't boot after I configure the boot order option in bios. Really need your help, please?

Thank you

Note: He did a complete installation of Windows 10 and not an upgrade, so there is no Windows.old folder in my Local disk C and there is no Downgrade to Windows 7 option in Settings > Updates & Security > Recovery.

Note: There is no security boot and legacy support in the bios for this notebook. Or my bios is not updated?

Immediately after powering on start tapping the F9 key at top of keyboard. This should open Boot options where your USB drive is an option. Use the arrow keys to move to and highlight/select it and tap Enter key.

Hi mate, thanks for the reply, I really appreciate your quick response. I tried pressing F9 and it redirects me to the Boot Option Menu. My booted flash drive is there so I select is (SanDisk). After selecting it restarts the notebook like nothing happens and redirects me to the desktop. What do you think is the problem?

Are you sure your flash drive is bootable?

What software did you use to create it?

Have you tested it on another machine to see if it is bootable?

Yup, im sure my flash drive is bootable. I use rufus and a Win 7 AIO iso.

Have not tried into other machine yet.

You may need to disable secure boot and/or enable legacy boot in the BIOS settings for Windows 7 to work. However, if you don't have those options, as you say, that's not the issue here.

Hi, thank you for the response but as you can see on my post my BIOS does not have those two options. (Secure Boot/Legacy Support) and I am not sure why.

Your laptop shipped with Windows 7. Secure Boot was  introduced on Windows 8 machines as far as I am aware-at least on HP machines. I noticed you said a Windows 7 AIO-room for error there,imo. Did you create it with settings for MBR and BIOS-not UEFI settings? I would test the flash drive on another machine (non-UEFI) before beating yourself to death over this. Your friend evidently managed to get the laptop to boot from a bootable disc or flash drive to install Windows 10 ,perhaps he can help?
