    Assume you have the windows bootlader working. Then you have to boot linux from in windows boot menu.
    Now you can boot in linux so please do:


    sda3 is your linux partition in this example. /mnt/share is some directory (doesn't matter).so do this command in linux
    dd if=/dev/sda3 of=/mnt/share/linux.bin bs=512 count=1
    now put linux.bin on your windows C-drive root directory so C:\linux.bin

    later in windows you can do (elevated command prompt):

    bcdedit /create /d “Linux” /application BOOTSECTOR


    BCDEdit will return an alphanumeric identifier for this entry that I will refer to as {ID} in the remaining steps. You’ll need to replace {ID} by the actual returned identifier. An example of {ID} is {d7294d4e-9837-11de-99ac-f3f3a79e3e93}. Next, let’s specify which partition hosts a copy of the linux.bin file:
    bcdedit /set {ID} device partition=c:


    The path to our linux.bin file:
    bcdedit /set {ID} path \linux.bin


    An entry to the displayed menu at boot time:
    bcdedit /displayorder {ID} /addlast


    and finally, let’s specify how long the menu choices will be displayed:
    bcdedit /timeout 30

    Are you very very sure you boot from DVD? If you get File: \Windows\system32\boot\winload.exe Status: 0xC0000001"
    from DVD .... this is impossible

    About the linux.bin file, I tried to do the trick, but in fact the "C disk" already contained a linux.bin file, which was identical...

    Besides that, yes I am booting from the CD (it's a CD, not a DVD, in case it could change anything): at the very start, I get a message "Press any key to boot from the CD/DVD", and if I do not, I have the standard grub menu. If I do, I have the message "Windows is loading files" for a minute or two, and then my error message.

    Also, it is
    File: \windows\system32\boot\winload.exe Status: 0xC0000001"

    There is no letter at the beginning.

    so linux.bin is already on C-disk fine! bcdedit commands are understandable for you?
    I don't understand why recovery cd doesn't work!
    Error message comes from grub I think, though you booted from cd. very strange
    Is there a way in linux to delete mbr? Try something link this

    How to fix your Windows MBR with an Ubuntu liveCD*|*ArsGeek

    do it from within linux. after that repair disk should work
    of course have a ubuntu recovery cd or something like that available to rescue in case of problems

    Thank you for your help.

    I will try that and keep you informed (I will probably do it tomorrow).

    In fact, if that's the reason, I think Windows should start normally after, even without repair CD (though I don't see how it could happen).

    And no, I don't know what BCDEdit is, but I can look that later.

    You must mark Win7 partition Active to tell Startup Repair where to repair or rewrite the System boot files. Partition - Mark as Active (Method Two)
    Startup Repair - Run 3 Separate Times

    Be aware that often GRUB corrupts Win7 beyond Repair. It's best to install Linux on separate HD's booted via BIOS to keep each independent.

    If not follow this after repairing Win7: Dual boot Ubuntu-Win7

    If repairs fail you can run Asus Factory Recovery from its partition, or use a Win7 installer to clean reinstall following these steps to get a perfect reinstall of factory OEM: Reinstalling Windows 7

    File: \windows\system32\boot\winload.exe Status: 0xC0000001"
    =>looks like a windows bootmgr error btw. Are you sure you boot from grub? Check which menu you get to select "Win7" or "linux". Do you see something like this? http://www.instablogsimages.com/imag...Fb4g_25552.png
    So windows bootmenu?

    Are there any grub files on C-drive (most likely a grub file or grub folder in root folder)?
    Does C:\bootmgr exist?
    Does C:\boot\bcd exist (hidden system file)? Post that file on forum, it's windows bootmenu

    Okay, I found the reason why I couldn't start the Startup Repair. I downloaded the iso file a second time and made a diff, and saw that the files were different. I had already noticed that some large files were corrupted when downloaded with the wifi under ubuntu, but no such thing with the cable yet... (I suddenly realized the corrupted files in the error message had to be on the CD).

    So I downloaded and burnt the repair CD from an old XP computer and it worked.
    After the first run, Startup Repair found no problem, but Windows still couldn't start. I did a memory check and right now the repair is trying to restore a previous configuration. I will keep you inform.

    Yes this was the active partition.

    If not follow this after repairing Win7: Dual boot Ubuntu-Win7
    Thanks, I'll look at that after.

    If repairs fail you can run Asus Factory Recovery from its partition, or use a Win7 installer to clean reinstall following these steps to get a perfect reinstall of factory OEM: Reinstalling Windows 7
    Yes, I think there is something like that (restore factory state or something), but I hope I won't be forced to do that.

    No, this is grub bootmenu.

    I can't post this now and I'm not sure it would help by now... thanks anyway.

    Last thing, I'm wondering how I can trust Linux updates if the files downloaded can be corrupted; all the more as there are grub updates regularly. Anyway, this is not a Linux forum

    Thanks again and once more I'll post here if I can finally boot or if I have other troubles.


    Edit: apparently now I can start windows normally (after restauration of last good known configuration). I don't know what caused the trouble, I hope the next updates won't screw everything again. Also, I had to reinstall Firefox to be able to launch it (it was on auto-crash mode), but I guess several program will have troubles after this...

    At least I learnt a few things, thanks again.
