Just now while installing Windows 7 from a bootable USB which wasn't successfully because of some bizarre Select driver to be installed. issue, before the setup had even started, after which I thought of connecting my passport drive which has Ubuntu on it to check what was wrong, which too didn't boot because of this. (No the Ubuntu wasn't corrupted I checked it elsewhere, worked fine).
The main question:
After connecting my passport drive it occurred to me, what if I hadn't taken out my Windows 7 bootable USB. Which one of the two bootable would have taken priority over the other? And why? After all in the BIOS we only specify USB as the first boot priority not the USB port priority.
What on earth do you think is wrong with this machine I am trying install Windows 7 on? I have tried all the drivers at my disposal.
