I have Two wim files at grub4dos for USB memory, the one is win7 pe, and the other one is win 7 installation. This is the menu.lst for my USB. title 1-1. Win7PE \n find --set-root /BOOTwin7peMGR chainloader /BOOTwin7peMGR root title 1-2. Win7 Installation \n find --set-root /bootwin7installmgr chainloader /bootwin7installmgr #title root The Win7PE's wim file is located at "bcd/man7pe_Boot.wim" and "Win7 Installation"'s wim file is located at "sources/boot.wim". But when I click "Win7PE" or "Win7 Installation", usb boots "Windows 7 installation" sreen. Is there any tool for wim boot menu?
