    The Windows boot partition sda1 is just for Windows in MBR. It looks like you created a /boot partition for Linux (which for most desktops is not required) and overwrote the Windows code.

    Do you have a Windows 7 repair CD or full install DVD? You need to use gparted to move boot flag to sda2 and run Windows repairs on sda2.

    Boot files - you are missing the first two, but you can repair your main install and put them there:
    Vista/7 (with 7 the first two files are usually in a separate 100MB boot partition)
    /bootmgr /Boot/BCD /Windows/System32/winload.exe

    OK I'm going to use a friends repair disk. Will there be any issues using the Windows files as in wipe them? Is it going to be a problem that it's not the same disk that was originally installed?

    As long as it is the same version and the same architecture, it should work. If it is not the same, then you can download the proper image via the links supplied by oldfred

    I have used a Windows 7 repair USB to run chkdsk on my old XP. It did write a Windows 7 boot sector, but I was able to write an XP boot sector with some Windows commands.

    I have links we used to recommend for repairCDs, but they now charge $10. I think the more important version difference is 32 bit vs. 64 bit. If that is the same the repairs should work.

    I did try a windows7x64.iso from a certain Swedish web site. I used a USB but when it booted there was just a blinking backslash. I took a look at the gparted. I definitily just f'd up and overwrote sda1 (I think it's ext4 /boot now). Surely there's a way to do this without reinstalling Windows7.....What were those window commands?

    You also overwrote sda1, so you cannot recover it.

    But Windows works from one partition, but you have to have boot flag on sda2 not sda1 as Windows only repairs the boot flag partition.

    From Windows repair:

    You will need to boot with your Vista/Windows 7 installation disk or repair disk. Hit Enter at the language selection prompt then hit "R" to get to the repair section. You can then select the automatic boot repair tool, but it often will not do any good. Then select the command prompt (console) and type in the following commands:
    # is comment do not copy or type comments
    BootRec.exe /fixMBR #updates MBR master boot record do not run if you still want grub
    chkdsk C: /r #(have to run /r or /f as separate entries) rerun until no errors
    BootRec.exe /FixBoot #updates PBR partition boot sector or see bootsect.exe commands
    chkdsk c: /r
    BootRec.exe /ScanOs
    BootRec.exe /RebuildBcd

    Re: Dual boot Backtrack/Windows

    Right, I got the iso and followed the command lines you suggested. Everything worked untill the last BootRec.exe/RebuildBcd. "The volume does not contain recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted." There is a chance of it being currupted because of a Brasero error during burning. I've fixed the error so I'll burn it again and give it another shot.
