No common CD-ROM drive was detected

Hello,

I've downloaded the ISO file "openmediavault_0.5.0.24_amd64.iso".
I've used "unetbootin-windows-585.exe" to built a bootable USB key with this ISO file.

There is no cd-rom drive on my server.
I boot correctly from my USB key but at the third step "Detect and mount CD-ROM", I obtain the error "No common CD-ROM drive was detected"... and I can't install OMV!

Could you help me

Thanks a lot,
Chris

I've resolved my problem by using Rufus instead of UNetbootin.
