Are you cloning the partition only or you also cloned the MBR (actually just Disk Signature of the MBR is needed)?
Dhilip89, thanks a lot for your work.
I patched my Win 7 x32 (starter) installation, and it's succesfully boots from USB HDD.
But, when I cloning this bootable partition (by Acronis) to 16Gb USB stick (transcend), I'm getting BSOD 0000007b at several seconds after booting begins. Tried to disable swapping and forced to assign "HDD" type to my flash stick in BIOS, but no success.
What else I can try?
