how to stop win7 presetup from scanning files

[biatche]

Past BIOS > Finding boot device > (boots off windows 7 setup device)

You find a long bar, saying i think it was windows is loading files?... then comes the bootsplash starting windows before it enters initial windows setup gui screen.

So I presume that during the first stage -- before bootsplash, it silently ?scans all files? on all drives and it can take a very long time. I don't need it to do that. Sometimes though unusual, with ??certain files?? on the drives, it'll stall at bootsplash until i erase the entire disk. Very irritating. I don't need it to scan, I know what I want to do with my setup.

So yeah, how do i disable that?

Uhm what?

You start the computer, bios does it works, windows loads, you login.. thats it.

bios > boot device (usb) > preload some files > win7 bootsplash > win7 setup gui

that part there can take ages sometime. takes longer when there's data on my hdd. seem to take shorter time with mbr is zero'd.

i want to stop preloader from scanning or doing whatever that it's doing that takes very long
