    Exclamation HELP! Windows 7 bootloader help!

    Hey guys,

    My windows 7 bootloader is working anymore, after i adjusted my harddrive. Before it was set up like this:

    {[Windows 7 Partition]--[Windows xp]--[Linux Part.]--[Linux Part.]}

    I deleted the other 3 partitions,

    {[Windows 7 Partition]-----------[Unallocated space]-------------}

    And then i resized the windows 7 part to take up the whole hdd

    {-------------------[Windows 7 Partition]-----------------------}

    However, The windows 7 bootloader gives me an error now ever time i try to use it.

    The error is like this:

    ---------------------------------- Windows Boot Manager---------------

    Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

    1. Insert your windows installation disc and restart your computer.
    2. Choose your language settings, and then click "Next."
    3. Click "Repair your computer."

    If you do not have this disc, Contact your system administrator or computer manufacturer for assistance.

    Status: 0XC0000225

    Info: The boot selection failed because a required device is inaccessible.

    --------------------------------------------------------------------------
    I booted into ubuntu 9.04 live cd linux and verified that acronis disk director suite did everything correctly. there was one nice whole partition which had all of my windows 7 files in it.

    I also tried installing ubuntu on my hdd, to see if GRUB would help at all. no luck, it simply loads the same bootloader.

    I also tried booting into the windows 7 cd, and did startup repair. it ran one pass and said problem corrected and i rebooted, but to no prevail. on the internet, people said you have to run it multiple times, since it fixes only 1 problem per pass. so on my 2nd pass (and every pass after that) it kept tell me that it was not able to fix the problem and that i should send the problem to microsoft. Here's the log of the cd's startup repair option:

    I also went into the recovery counsle to see if i could manually fix it, as i read of on the internet.

    Here's the log for the counsle. I first tried the recommended /fixmbr /fixboot, but i also found other options which i tried as well.


    X:\Sources> bootrec /fixmbr
    The operation completed successfully.
    X:\Sources> bootrec /fixboot
    The operation completed successfully.

    The Operation Completed successfully-MY ASS.

    I jumped up from windows xp to windows 7 since i didn't want to deal with the piece of shit they called vista. I know that with xp, one can simply edit boot.ini to point the NTLDR bootloader to the correct partition and specify the type of Os that resides there. Now, i know that with vista and forward, it uses Vista boot manager in conjunction with the NTLDR bootloader, but there is no boot.ini image and the only way to edit it is either with msconfig or bcdedit (or easybcd for that matter).

    How can i fix this problem? I doubt that either of those latter-mentioned files will work via WINE on the linux platform.

    Also, my apologizes for posting stuff here in an out-of-order troubleshooting method. I've tried just about everything i can think of, and i really dont want to endure the agony of reinstalling and recovering ~240 gigs of SOFTWARE and important files (not HD porn movies). PLEASE help me!!!!!!

    Re: HELP! Windows 7 bootloader help!

    Did you have 100MB partition somewhere on the drive that you removed? If not you might have removed your bootloader files. If the small partition is still there is it set active?

    I dont know if acronis supports Win7 yeat and if there is any differance between Vista W7 NTFS that could have caused this but in Vista there is an option to expand a partition from within the OS that works well, you'll find it in Manage -> disk managment.

    Not sure if it was a 100 mb partition, but i deleted 2 other partitions besides the windows ones. Idk if they were being used for windows, but one of them was defi. an ext3 partition.

    As for bootloader files, the bootloader is still there, it just cant load up windows 7.

    I tried that, and it didn't do much for me. it's great for someone that deleted his bootloader and what not, but for me, it seem like i'm going to have to back up everything and then zero my drive

    Re: HELP! Windows 7 bootloader help!

    I'm in the process of rebuilding the windows 7 bootloader. After trying command 4 it says (Scanning all disks for windows installations. Successfully scanned windows installations. Total identified windows installations: 0 The operation completed successfully. What's the difference between a volume and a partition? In diskpart when i select disk 0 and list partitions it lists 2 partitions one being system reserved the other being the main windows partition. When i list volume though the main windows volume doesn't exist in the list? *edit 20min later* I've determined that one disk 0 partition 2 which is the windows partition, it is not associated with a volume. Only partition 1 is associated with a volume. That means the windows partition doesn't have an assigned drive letter. I have tried to assign one, but you have to specify a volume, yet it doesn't exist. Understand? Help would be highly appreciated.

    1.) bootrec.exe /fixmbr

    2.) I:\boot\bootsect.exe /nt60 all /force

    3.) del C:\boot\bcd

    4.) bootrec.exe /rebuildbcd

    Re: HELP! Windows 7 bootloader help!

    Well, you certainly tried all MS avenues to fix this problem.
    When the MBR is botched up with something we can't see, I usually would try
    delpart on a 98 boot disk, I believe its a free utility you can find on like 2k CD.
    Or, you can try to download OEM utilities that have low level formatter to clean out all the tracks on the HDD, sometimes they have a specific formatting of the first 6 tracks(which includes the MBR). I didn't see if you wanted to wipe the drive or save the data, in which case Low Leveling would wipe your stuff.

    Re: HELP! Windows 7 bootloader help!

    FIXED - Used Acronis True Image to backup the partition to another disk. Deleted the partition then used acronis to recover using the backup, this time not using the original backed up MBR. Put it back in, windows 7 was able to repair the problem automatically. Now here i am! damn i'm good!

    Glad you got it sorted out out. If the primary OS partition is removed for whatever reason the bootloader file will sometimes end up on a USB stick or another drive making the OS partition non-bootable.

    Just to add to this thread, if you can get into one of the operating systems, you can use EasyBCD to rebuild the bootloader. Very easy to use.

    Nice fix! I fought with his on a customers system for awhile. NONE of the stated fixes have worked or made a difference. The whole boot system got messed up after plugging in an external USB harddrive.

    SO...my fix was this:

    Using Acronis as well...i made an image of only the primary partition.
    I then deleted ONLY the primary partition on the drive in question.
    Reimaged the primary image onto the empty partition.
    Booted from a Win7 repair disc...let it find and fix repairs and restart.
    Had to reboot to repair disc a second time so it would then see the Windows install.
    Choose 'repair startup' option from the repair menu.
    VOILA! Boots in quickly and without issue.
    Great fix...i appreciate you posting this because my next step was a wipe and reload and i did not look forward to that on this system.

    thanks again!

    Re: HELP! Windows 7 bootloader help!

    I only use 3 commands of
    Code:
    bootrec /fixmbr
    if I need a Win7 version of the MBR in the C: drive.
    Code:
    bootsect /nt52 c:
    if I only want NTLDR in the boot sector of C:. For bootmgr I change /nt52 to /nt60. bootmgr can boot NTLDR as an alternative so it covers both.
    Code:
    bootsect /nt60 c:
    For rebuild BCD of all Vista and Win7 my command is just
    Code:
    bootrec /rebuildbcd
    I even use a Dos Fat partition as the "C" drive and arrange Win2k, Xp, Vista and Win7 in logical partitions.

    The motive of using a Dos partition for housing all MS boot loaders is enable me to sneak Grub inside so that it boots the rest of the 35 Linux in the same hard disk. Grub can read a Dos partition and uses the same \boot directory (as Vista/Win7's bootmgr) for residence.
