Is it possible to boot officially (not modified) Windows 2003 (or XP) from USB?
If not, then it will not be a standard feature. And for this special will have to make changes in the kernel RoS.
Well, that defender version is microsoft provided, and the boot window splash seems similar to Win7.
But, that aside, even XP boots at least enough to request an installation. I've just tried it with an XP SP2 install disk and it will boot (text mode) to the point of asking about what I want to do, setup, repair, or quit.
This is from a USB cd/dvd drive on an Acer netbook.
I am not currently able to reach any similar point with either the livecd or bootcd on the same hardware (locally built from reactos svn r73488) .
Both reach point and seem to get past loading boot drivers, then, bootcd (one try only) leaves screen blank and seems hung,
while livecd (several tries) reaches a point at KDB prompt (having logged to screen) with last item at top of screen indicating ZwOpenFile failure for \SystemRoot\system32\drivers\vbemp.sys with status 0xc000003a at sysldr.c:3025 (which is STATUS_OBJECT_PATH_NOT_FOUND), although vbemp.sys is to be found on the disk when viewed from windows. Previously that was top line, but last try there is a msg just before about pnpmgr.c:4059 IRP_MN_QUERY_DEVICE_STATE failed with status 0xc00000bb, which I haven't looked up yet.
I think ROS needs to boot from usb enough to at least install.
