hi folks, i have the same problem as mentioned from "Elendil0" earlier in this thread i used the latest beta of WinSetupFromUSB to make an multiboot usb-hdd with 3 primary partitions and an additional 4th partition for some files and stuff (all as NTFS). 1st partition = win XP sp3 x86 (unattended) + win XP sp3 x86 (normal) + win 7 (All In One, selfmade with WAIK from the 2nd link in first post) 2nd partition = win 7 custom selfmade version (patches and stuff, x64) for testing 3rd partition = win 7 custom selfmade version (patches and stuff, x86/x64) for testing all installed in this order. the win xp installations / setup works fine at my test-laptop (an old asus extensa 4100), no problems here. but the win 7 setup hangs at the same point described in the quote above. the win 7 AIO iso burned on a dvd-r works perfect on my test-laptop. in diskpart i just see the intern installed laptop-hdd, no usb hdd any advice to solve this problem? thanks in advance and sorry for my bad english
