Hi, I encountered problems of installing Windows 7 from USB. Let me describe my procedure to do that and show you what happens as follows. Procedure to make a bootable USB for Windows 7: 1) Reference the link http://www.hiren.info/pages/bootcd-on-usb-disk and do the same things step by step. 2) After installing Grub4Dos, Extract and copy all files from DVD ISO of Windows 7 to my USB stick. 3) Edit and add a title for menu.lst under the root of USB stick. title Install Windows 7 find --set-root /bootmgr chainloader /bootmgr An error message is shwon after entering "Install Windows 7" in Grub4Dos: Windows Boot Manager says Windows failed to start. A recent hardware or software change might be the cause etc, etc, then -> File: \Boot\BCD Status: 0xc000000e Info: An error occurred while trying to read the boot configuration data. Do I miss something to configure Grub4Dos or lacks of instructions to set the MBR of my USB stick? Need your kindly help, thanks a million! P.S My USB stick works here as an USB-HDD for ASUS P4C800-E motherboard.
