  1. for those who think it is stupid question i give a hint... it is not.
    Main problem is to make bootable pendrive. SYstem does NOT accept command bootsect.exe if the system i am using is 32 bit and i want to install 64 bit. That is why i am asking for some help :)
  2. Find a working Windows 7 PC
    Go to control panel > back up and restore
    Create system repair disc (on the top left)
    Select the DVD RW drive or whatever you have a optical drive writer.
    Create disc - after some time it will be ready.
    Copy these files to a freshly formated USB stick

    FORMAT THE USB DISK AS 'ntfs' or this does not work.

    Assume that the flash drive is F and disk 1 in diskpart.
    Create 2 folders on the flash drive - boot and sources

    cd c:\recovery (could be c:\windows\system32\recovery)
    dir /a:sh
    cd YOUR_GUID_DIRECTORY (only subdirectory in c:\recovery)
    dir /a:sh
    xcopy /h boot.sdi F:\boot
    xcopy /h Winre.wim F:\sources\boot.wim
    cd c:\windows\boot\
    xcopy /h dvd\pcat\bcd F:\boot
    xcopy /h dvd\pcat\en-US\bootfix.bin F:\boot
    xcopy /h pcat\bootmgr F:
    attrib -r -s -h /s F:\*
    list disk
    select disk 1
    list partition
    select partition 1
    list partition

    Eject the flash drive and boot from it.

    The above seems to work pretty well, i got it from a online search.
    cd YOUR_GUID_DIRECTORY (only subdirectory in c:\recovery) < this bit is the hardest part, its in a really terrible location i found it by dir /s boot.sdi and it pops up.

  3. I have a silly question: have you tried to boot on it without running the bootsect.exe, just after the copying? It is said to be working on some computers.
  4. I'm also reading that a 32 bit bootsect.exe (from a 32 bit installer, or Easybcd bin folder) also does the trick.
  5. Create or download an iso format of W7 64 and use Windows Disc Image Burner
