W7u - fresh install, no dvd-drive, ethernet and usb not installed

Hi, I'm new here, and didn't know exactly which forum to post this is, as it covers more than one topic (but it's all connected), so I put it here.

My girlfriend got a new computer for school, a HP 14" ac-180no (ugh), and wanted Windows 7 on it (it came default with W8).
Turns out, it's a mess to get W7 on this thing, as it considers W7 to be a "legacy" OS, and is probably primarily meant to be used with W8 or W10.
So I set the BIOS to legacy mode. No biggie. Trouble is though, that W7 setup would not detect any usb ports. None.
I could boot from USB, but as soon as I entered the setup, it was not available. Loading the drivers from HP's website did not help either (I dumped them on the HDD; had not formatted yet, and loaded them from there).
I also got an error that it could not create a system partition, because of the USB stick in the port (which it could not see, seemlingly). If I removed this, I got a 0x8030001 error, and it kept asking for additional drivers, and I could not continue.

And the BIOS on this thing, is so limited, that the only thing I can change, is the bootorder. There are no options for forcing usb 2.0 or any other p&p, uefi etc. settings. Bootorder and the time; that's about it.
The only time the USB drive is readable (or at least, recognizable) is in HP's boot-menu. As soon as W7 setup loads from it, it's gone - as far as W7 knows, it would seem.

In order to finally be able to install W7, I used the still working W8, created a small partition on the HDD, dumped the W7 setup files, and used DISKPART to make it bootable.
I didn't think to copy the drivers on to that partition before installing W7.
Without any drivers available, I'm stranded with a computer that I am seemingly unable to transfer any files to whatsoever.

Summary: Fresh windows, no usb drivers, no ethernet drivers, no dvd-drive. I have a computer I cannot get any files onto. Help!

Yeah, that was one of the things I tried when the HP drivers wouldn't work. I used double driver for that.

My current problem is that the w8 installation is now gone, and W7 can't find suitable drivers for neither usb nor ethernet/wireless :-(

Ok, so I managed to sort it out. I used the Windows 8 installation files to start the setup, and from there I could use the console (shift+F10) to copy the required drivers onto the HDD (W8 installation found my usb-ports).
For anyone wondering, go here:

To download a working W8 installation. You don't need any serial, as you don't go through with the installation, you just use it to get to the console.

And i'll see you in 90 Days when you get the non-genuine.
NO downgrade rights for 8>7 on that comp, unless you buy a W7 licence

I already have a W7 license, that's why I went for W7.
