New PC build help with bootable usb win7

[ZenDragon]

Ok .. so i’v just built my new PC.. Ryzen 1700x, AMD radeon rx 480, deepcool captain 240ex, asrock motherboard, i have a SSD and an HDD.. also a brand new copy of win 7 pro.. but no Disc drive.. decided to do the bootable usb option.. and i now have the iso on the usb.. but, when i start up, enter bios and see that the usb drive is recognized.. but it boots to a black screen.. nothing at all???

Hi @ZenDragon and welcome to PCHF

Does your motherboard use UEFI for the boot? If so, Windows 7 will not boot in any way, shape, or form. It must be booted via Legacy boot.

i think it does but has a setting section CSM with options for Launch PXE OpROM Policy , Launch Storage OpROM Policy and Launch Video OppROM Policy .. all with either UEFI only or Legacy only or off..

im not sure exactly what those should be set at, but with all set to legacy only, i get the message ’ Reboot and select proper boot device’

I really need to get this working… can anyone tell me what I should do? a way around this? I have the product key, no disc drive.. iso on usb… how do i load windows?

We need your exact motherboard model.

ive tried booting in each possible setting (UEFI/Legacy) variant .. for the ‘Launch video OpROM Policy’ if I have it set to UEFI it comes up black screen after the F2-F11 pprompt… if I have it set to Legacy, it says “select proper boot device”

You say you have the ISO on USB. Is the USB device bootable?
How did you create the stick?

Note: I have never succeeded in booting Windows from USB even though I have created more than 2 dozen bootable linux USB sticks.

it is bootable… actually, the first time it was made using Rufus by a tech from Microsoft. the system i built doesnt have an optical drive, but i had wired one in, though it wasn’t reading… I thought the issue was the DVD drive so I was talking to Microsoft and he reccommended the usb boot and ppulled an ISO for me and loaded it on my USB. I was reading later on about NTFS and Fat32 and I didn’t remember which he had used, so I went through the pprocess a second time using the command prompt method instead. the Usb works on this machine but when I select it on the UEFI bios I get a black screen .. secure boot is disabled .. bios reads both my SSD and the USB along with the USB partition.. Ive tried setting the partition as 1st boot opption as well… same result..

[ZenDragon]

Jmarket- what do you mean it has to be from legacy boot? i can set the opption for legacy? also, is there a way that I could wire my SSD into this computer im using, put windows on it, then reconnect it to my build and start it up that way?
