    Thanks SIW2. I tried it, googleing to see which one was my system partition. I thought it was C: 100mb so used that in disk part but didnt work. Then I got a reply from my friend saying no it's E: 60gb that I want. So I ran it again, trie that, and tried the boot mgr for all, but still doesnt work. I'm getting "Reboot and select proper boot device or insert boot media and press a key"...

    My Bios is detecting my SSD but will not put it in the boot list??

    Any ideas?

    EDIT: AHA I'm getting somewhere, now I have got the SSD recognized as a boot device, I've got "BOOTMGR is missing
    Press Ctrl Alt Del to restart"

    ??

    Hey guys - I'm in a bit of an emergency at work here.

    I'm on an HP workstation, originally it has CentOS installed (I think on one HD), and XP on another - I installed another HD, and upgraded to Win 7. Everything has been working perfectly, even after about 4Gb of updates !
    However, then what I needed to do was format the drive with XP on it so that I can use it to store our image sequences (VFX work).
    After I killed the partition and told it to format (using free software from filehippo iirc) - it then won't boot into Win 7. It keeps trying to go into some kind of CentOS option list.
    Using the previous commands - I can see that win 7 is still drive C/vol 1 but I can't seem to get it to boot at all.
    (no options in the bios either) - I also tried disconnecting the other 2 HD's inside, and just the main Windows one but to no avail.

    Argh, not sure what to do - and I've got a massive pile of work now haha.


    Tried:
    ----------
    Diskpart

    lis vol

    ( find the vol letter e.g C or partition number e.g. 1 for the system partition )

    sel vol C ( or sel vol 1 , obviously use the correct letter or number)

    act

    exi
    -------------------------------------

    And tried

    bootrec.exe /fixmbr
    bootrec.exe /fixboot
    bootrec.exe /ScanOs (finds it)
    bootrec.exe /RebuildBcd (gives me the 3 options, yes/no/all - but says Eliment not found after Y or A)




    I've got a feeling I need to some how get vol 1 set as primary.

    Hmm, according to the 'list partition' command it is primary.
    No idea what to do - in a panic !

    EDIT:
    Disconnected the other drives again, and retrying the Win 7 DVD tools, it seems to have picked something up this time...

    EDIT 2:
    Ok I'm sort of getting somewhere.
    When I disconnect the other 2 drives, whatever it did in that repair thing from the DVD allows me to boot up Win 7.
    So I'm now trying to work out how to boot up but with the other drives connected, this seems to be what's causing a conflict.

    Never mind that bootrec stuff, hit it with bcdboot.

    bcdboot win7partitionletter:\windows /s otherdriveactivepartitionletter:

    You don't have bcdboot.exe in your installed windows, so do it from the booted dvd.

    I'm just checking out Gparted to help out as well.

    Didn't work out for me, it's this ruddy Linux partition(s) - so I'm going to kill them, and someone else can install that another day

    Well, I've re-arrange some cabling, pulled out the Linux drive and it boots into windows at least for now.
    So I'll get our tech guy to look whenever he comes in next - serious weird stuff !

    gparted is very bad.

    if you have same issue again

    use minitool media builder to create a usb flash partition manager.
    boot from it
    fix mbr or gpt whatever you had

    I found out why there was a problem, there is some kind of hard wired device in our systems that bring linux install thing up (and the SATA cabling order made a difference) !
    So no amount of bits of software would actually solve my particular issue, anyway - for now it's cool and our tech guy will end up sorting something out in the future. But for now, thankfully things are ok.

    No valid system partition


    Hi SIW2,

    I've run into pretty much the same trouble and could really use your help. This is the most relevant page I've found.

    I was using my pc when it just went to the bsod. No new hardware and since the problem disconnected all usb peripherals except my mouse. No new installation of software. I'm running windows 7 professional on an ocz vector ssd. I've tried swapping the memory sticks out as well and reconnecting the cables. I'm running the windows recovery wizard.

    My ssd is no longer detected as a valid system partition. Both in command prompt (diskpart) and the partition wizard tool you linked to, my ssd is not listed at all. Is there anything else I could try? I can also no longer boot from the partition wizard iso cd and I'm given the error that it does not contain os files.
