    For some odd reason, after doing some changes to my partitions in Windows 7 and restarting my computer, I got the ol' "BOOTMGR is missing" message. I have the Windows 7 Repair Disc image file and a 4GB USB Flash Drive, but, sadly, no CDs. Is there any way that I can put the image file onto my USB Flash Drive and boot from it with my Acer Aspire X1200 desktop computer? Thanks in advance.

    Yes, with another computer. Use Xcopy to copy everything to the usb.... move the usb to the broken computer and set the bios to boot to usb. Actually you only need 3 files from the repair disk.... I'm doing this from memory so I may make a mistake.... but I think they are:

    1. bootmger from root
    2. bcd from /boot
    3. bootwim from /sources

    They have to go in the same locations on the usb

    I think you can just change to the usb and run

    xcopy x:\bootmgr
    xcopy x:\bcd /s
    xcopy x:\*.wim /s

    and it will build the usb correctly...
