What happened?

The flash drive is GPT formatted. I have Windows 10 and Windows 11 ISOs on the Ventoy partition. I can boot any of those ISOs, but when I click the "Install now" button, instead of the product key dialog, I get the famous "A media driver your computer needs is missing" message and can't continue any further. At this point I've noticed there is no install media, only the Ventoy drive and the X drive (the installer session).

This happens on my HP ProBook 450 G8 (11 Gen Intel, 16 GB RAM, m.2 nvme ssd).

My old rig (Gigabyte H77N-WIFI, i7-3770, 16GB RAM, SATA SSD) has no such problem. The install media appears during the install and I go to the product key dialog, then to the edition selection and then to the partition editor with no issues.

All tests have been made with UEFI boot (the ProBook has no Legacy support). I suspect there is something wrong with the HP's UEFI implementation, but can't be sure.

A driver is needed for the target drive to be detected. Usually the main board manufacturer will cover this situation on their website.

[philippetev]

The target drive is not the issue here. I have no install media to install Windows from. Whatever magic Ventoy is doing to somehow mount the ISO file as a physical drive / install media in the installer, it's not doing it on this laptop. The target drive appears right after I install the Intel RST driver and running diskpart in the command prompt confirms it. As I said, not a problem.

I have the Windows 10 22H2, Windows 11 22H2 and Windows 11 23H2 ISOs on this drive and it happens with all of them. The checksums of those ISOs are correct.

[steve6375]

So it is standard Microsoft iso? How do you load rst driver if no usb can be seen?

[philippetev]

Haven't said that no usb can be seen. The USB ports work just fine and all the USB drives I attach during the installation are visible in the browse dialog. The only missing thing is the install media, you know, the ISO file, mounted as a drive, so the installation can't find the install.wim/install.esd file and can't continue.

[steve6375]

Are you using a standard, unmodified Microsoft ISO - made and downloaded from Microsoft? Ventoy injects its own winpeshl.exe file into the X: ram disk and that shell has additional code to install the ISO as a virtual drive before calling the real winpeshl.exe. So it only works with standard Windows PE boot.wim files. It may not work with 3rd-party non-standard Windows Install ISOs. So maybe you could answer my question?

[philippetev]

I think I've solved it. Kind of. It was some setting/s in my BIOS. Restored the default settings, then set them again and now it injects those files correctly and the ISO is mounted. Thanks for the hints anyway!

[steve6375]

Interesting. Can you remember what settings you changed in the BIOS?

[philippetev]

Unfortunately, no. More importantly, I don't know which setting I've turned on, and obviously shouldn't have to... Usually only set the state of the NumLock and disable WoL, network boot and Secure Boot, that's it.
