    Corrupt boot sector?


    Hello,

    For a while now i have a stupid problem, which is like this:
    In the begining, it had the wierd way of reasigning letters to my partitions, making C: (windows) as D: and what was supposed to be the boot sector, whici is usually 100 MB (made automaticaly by windows), it assign the letter C:. Of course, this made windows not start anymore and i had 2 choices, either reinstall it, or use a backup. I use acronis backup and it seems it works to restore my windows and everything. In the end i thought i solved the problem making the boot files be writen in windows c:, there was a tutorial about makind drive c: active and then repair windows 3 times to make the boot sector in drive c. And it worked, one month almost without the drive changing thing.
    But today it happed again, and i had an old tutorial about how to use the windows cd, use repair and then cmd and there, using this comands "dispart" "list volume" "select volume c" assign letter = C, this should have assign a partition the letter i want. Bad part was that i found that windows had the letter C:, but in the table raw that sed FS (whici it seems its the partition format, ntfs), it sed ntfs for all partition but on c it sed Raw.

    My question is, wtf is wrong with my computer?

    Hi Jack

    Open up a Command Prompt as an Administrator :

    Steps

    Click on

    Type in CMD( Doesn't matter if its caps or not )

    Right-click or Press Ctrl+Shift+Enter

    Click on Yes to bypass the UAC window

       Tip
    You could even press Alt+Y


    Type in this command

    Code:
     chkdsk c: /f /r
       Tip
    Change the letter " c " to what your Windows Letter is

    what does /f /r do, i know that chkdsk c: means it will check drive c, but don't know what /f /r do.

    Also, the problem doesn't seem to be that it reasign letters, but a problem with boot sector or something, it sed raw under the partition c.

    Also, that only works if i get into windows, but i don't get that far, the computer just restarts.

    You seem a little confused as to what your problem is! You started with Windows re asigning Drive letters, but now you say you cant boot into Windows. How do you view your Disk management if you can't boot into Windows?

    You should be setting the drive letter to Auto in Acronis when reimaging. Drive letters don't just change. You may have a bad install with boot sector corruption.

    After you reimage with Auto drive letter selection, please post back a screenshot of Disk Management - Post a Screen Capture Image - Windows 7 Forums

    Also look over these steps to get a perfect Clean Reinstall Windows 7
    as this may be your best course if problems persist, but this time wipe the HD first with Diskpart Clean Command to clear the boot sector.

    Don't mind the unnalocated space on disk 1, its there like that for a different reason, had some bads on that disk and since i couldn't isolated them i deleted the partition and let it be, windows is on a new hard drive, disk 0, not a year old.

    Kind of don't want to formate the whole disk, but will do it if the problem persists.

    Can't i just remake the boot sector with bomands like bootrec /fixboot /bootrec /RebuildBCD?

    You've cut out System Reserved partition which is no longer booting Windows.

    What I'd do is delete that and C and focus on getting a perfect Clean Reinstall Windows 7 in the space, then after its set up and running perfectly capture another image to use in place of reinstall. I seriously doubt you have a perfect install using best practices so that would be a necessary precursor to fumbling around with a dodgy image.

    In the future use Auto drive letter selection, choose to reimage both partitions to Primary space, with SysReserved being marked Active, copy MBR and Track0 back to the HD.
