Laptop not detecting bootable windows 7 disk/usb

[Eben89]

Hi.. 

I am currently running windows10pro on my HP ProBook 450 G3 i5. I know this might sound silly but want to downgrade to windows7ultimate.

I created a bootable win7 disk and usb,  but when trying to boot from both disk/usb,  it doesn't detect any windows loaded on the divice I am trying to boot from. I know about the legacy support and secure boot,  but unfortunately I forgot my BIOS password,  and its hell trying to get .bin file from HP. 

But when I create bootable win8/10 and boot from the same usb or disk...it detects di windows but does not want to detect win7. I maybe thought that the business notebooks doesn't support windows7 but please tell me I am wrong.

Help please,  how to get win7 on my Probook

Hi:

You need to use this tool to put the required USB 3 drivers into your W7 USB installation media.

Here is a video for how to use the tool...

Hi Paul

I tried the program , did step for step as shown on the video. Process completes successfully,  but stil doesn't want to boot windows7, even when trying to run it direct from the USB in explorer, like installing a normal program,  it tells me that "autorun" is corrupted.

Or could it be that legacy support is disabled and secure boot enabled? Because I cannot change that due to my BIOS password. But win10 boots perfectly even when legacy support is disabled and secure boot enabled,  and used the same method to make a bootable win7 usb to make win10.

Hi:

If secure boot is enabled, you wouldn't be able to install W7 because it is not compatible with secure boot.

HP has a policy they implemented last year where they will no longer send the required SMC.bin file that is used to clear the BIOS P/W.

So, you will have to run the notebook as is with whatever OS you can install on it..W8/8.1 or W10.
