I've tried a few of the following links ( ) but I cannot locate the 'Boot.sdi' or 'boot.wim' in the install directory. I'm now trying to make it portable but when it boots to WinPE to clone the drive its not loading the USB drivers (as expected). I have a new Lenovo AIO and I was able to finally get Windows 7 on the hard drive after many hours of trying to inject the usb drivers. It's like WinToUSB somehow crashes access to the stick completely. Interesting thing I found out is, that once the installation reaches 95% you can not open any partitioning tool cause it hangs when trying to read the USB SSD Partitions. But here I have exactly the same problem installation stops at 95%. I then fiddled around and in the end (as my system runs from UEFI disks anyway) I used diskpart to wipe the disk, convert it to gep and create ESP/EFI partition and windows partition (interestingly a 128MB msr partition also got created although I did not opt for that). It seems that it cannot create normal files to boot from.

I first tried MBR mode with a small fat32 partition 100MB and a big ntfs partition but the stick always hangs at 95% of the install process (after copying the vhd file I use as starting point). It reports itself as disk so I read the guide on how to prepare the disk in order to use WinToUSB. As my old USB stick was very slow I bought one of the fast GTX Voager USB stick without knowing that this stick is more like a mini external SSD as a normal USB Stick.
