How to use the Bootrec exe tool to repair startup issues in Windows by Britec You can use the Bootrec.exe tool in the Windows Recovery Environment (Windows RE) to troubleshoot and repair the following items in Windows Vista: A master boot record (MBR) A boot sector A Boot Configuration Data (BCD) store Note When you are troubleshooting startup issues by using the Windows RE, you should first try the Startup Repair option in the System Recovery Options dialog box. If the Startup Repair option does not resolve the issue, or if you must troubleshoot more steps manually, use the Bootrec.exe tool. Bootrec.exe options The Bootrec.exe tool supports the following options.
Use the option that is appropriate for your situation. Note If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD, and then run this option again.
By doing this, you make sure that the BCD is completely rebuilt. To do this, type the following commands at the Windows RE command prompt: bcdedit /export C: BCDBackup c: cd boot attrib bcd -s -h -r ren c: boot bcd bcd.old bootrec /RebuildBcd /FixMbr The /FixMbr option writes a Windows Vista-compatible MBR to the system partition. This option does not overwrite the existing partition table. Use this option when you must resolve MBR corruption issues, or when you have to remove non-standard code from the MBR. /FixBoot The /FixBoot option writes a new boot sector to the system partition by using a boot sector that is compatible with Windows Vista.
Use this option if one of the following conditions is true: The boot sector has been replaced with a non-standard Windows Vista boot sector. The boot sector is damaged.
An earlier Windows operating system has been installed after Windows Vista was installed. In this scenario, the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe). /ScanOs The /ScanOs option scans all disks for installations that are compatible with Windows Vista. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista installations that the Boot Manager menu does not list.
/RebuildBcd The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista. Additionally, this option lets you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD.

Using dual boot, I can access my H: (WIN7 boot) drive when I boot to my C: (Win-XP) drive but I cannot boot to Win7 directly. No change in hardware.
Been working fine for 2 years. All previous 'fixes' via DOS ( BOOTREC /FIXMBR, BOOTREC /FIXBOOT, BOOTREC /REBUILDBCD, etc.) didn't work. Maybe because I'm not comfortable working within DOS and did something wrong. Since I can see all Windows 7 files from C: (XP) is there an easier way to do this bypassing DOS? The Windows 7 errors I experienced in the automatic repair are:. Boot Manager failed to find OS Loader. Boot configuration data store repair failed.
Boot Manager generic failure. Windows cannot repair this computer automatically. I do see the file H: Windows Boot DVD PCAT BCD and H: Windows Boot PCAT bootmgr but Access is Denied for editing. Is access to these folders the problem? All previous 'fixes' via DOS (BOOTREC /FIXMBR, BOOTREC /FIXBOOT,BOOTREC /REBUILDBCD, etc.) didn't work. Maybe because I'm not comfortable working within DOS and did something wrong.
These are not magic fixes, each one does a specific thing and you shouldn't run fixes just randomly. Win7 errors are: Boot Manager failed to find OS Loader. Boot configuration data store repair failed. Boot Manager generic failure.
I do see the file H: Windows Boot DVD PCAT BCD and H: Windows Boot PCAT bootmgr but 'Access is Denied' for editing. Is access to these folders the problem? You seem to have pasted some random errors together, can you tell us when each of them happens? Have you these errors? Which suggested fixes did you try and why didn't they work? Boot Manager failed to find OS Loader.
This means that the Boot Manager either misses configuration to find the OS Loader or it is missing. Boot configuration data store repair failed. This means that an attempt to repair the BCD store has failed, it might be corrupt or inaccesible. Boot Manager generic failure.
This really depends on what you have been doing, doesn't say much. I do see files cut but get 'Access is Denied' for editing. Just finding the files on the disk and checking their permissions does not makes sense. Note that Windows actually protects you from tempering with it, they are not meant to be edited.
If any, the paths you mentioned are kind of irrelevant; DVD PCAT means you are looking into the Product Catalog part of the Boot Manager of Installer copied of the DVD. You could attempt to copy BCD from that to see whether that has any effect to restore your BCD to an original state, which could work; but don't forget to make a back-up first. You can gain permission, make sure that while doing so that you don't remove any permissions. Also make sure to take a back-up of the old BCD folder in case it doesn't work. Welcome to Super User! This was meant as a teaching point to troubleshooting problems, not to dumb you down.
For us to understand what exactly is going on we need as much information as possible / reasonable, to give you a random example: If I paste 0x8007005 would you be able to tell exactly what I was doing? Well, yeah, it's an Access Denied but that doesn't tell me what access is being denied. If I were concise, I would've said 'I'm missing information'; but without pointing out which information we don't get your problem solved. Could you please try again?

I've got an error status 0xc0000098 within the Boot/BCD files and when I do the /RebuildBCD command, it can't identify any Windows installations. The reserved system files are in the C partition, wich is active, and the Windows files are in the D partition. I have Ubuntu installed in my second HDD. Running Gparted, the D part is marked with an exclamation icon and when I try to mount it, I got this message: Error mounting: mount exited with exit code 14: Hibernated non-system partition, refused to mount. Failed to mount '/dev/sda2': Operation not permitted The NTFS partition is hibernated. Please resume and shutdown Windows properly, or mount the volume read-only with the 'ro' mount option, or mount the volume read-write with the 'removehiberfile' mount option.
For example type on the command line: mount -t ntfs-3g -o removehiberfile /dev/sda2 /media/94CE94 So, I guess the problem is it. The /RebuildBCD command can't access the Windows files to fix the BCD in the C part. Because it's hibernated. If I mount the volume 'ro' or mount it read-write with the 'removehiberfile' as the description says, will it fix it? If you need to mount the partition in read-write mode and are not able to or willing to boot into Windows and shut it down completely there is a third option.
However, it is not included here because it completely deletes hiberfil.sys and will cause you to lose all unsaved information in the hibernated Windows programs. The following is a quotation from man ntfs-3g about the option that would be used to do this. Removehiberfile Unlike in case of read-only mount, the read-write mount is denied if the NTFS volume is hibernated. One needs either to resume Windows and shutdown it properly, or use this option which will remove the Windows hibernation file. Please note, this means that the saved Windows session will be completely lost. Use this option under your own responsibility.While this could then give you access to the partition and be able to read/write it, it's possible that Win7 will no longer boot after that.

Are there reasons this might occur? I have about 4 different PC’s that are 5 or 6 years old but have had a fresh format of Win 10 on new SSD. I also installed new power supplies in some of them. The blue screen boot issue that’s resolved with these steps seems to be randomly occurring.
Some of the affected machines have had it happen 2 – 3 times- others just once. I do offsite support for a small office and thankfully they’re able to follow these on their own- but it’s certainly an issue I’d rather they not encounter, to begin with- and definitely repeatedly.

Hi there, I am running Windows 7 Professional on a Dell Dimension E520. Today while browsing my PC froze, so I shut down using the button and then tried to reboot.
It hung at the Windows logo screen, so I then rebooted and tried 'startup repair' options. It didnt seem to work and hung on that 'repairing' screen for two hours, then I headed back to google and found someone with similar probelm: And then tried again but used their method with command prompt. After the first and 2nd: bootrec.exe /fixmbr bootrec.exe /fixboot both succesful I then tried bootrec.exe /RebuildBcd But, it returned: 'total identified windows installations: 0' Then, realising I was in x: drive instead of c: I tried to change directories but when I typed c: it seemed to move there but I couldn't type anymore when it had, so I seem to be stuck in x: and have no idea whats going on now! EDIT: BACK IN BUSINESS! Thanks for all your help.
So the problem was that it seemed that startup recovery was not working properly and was looping after my PC froze then I rebooted but it would not boot, then after trying a bunch of things I freaked out and came here and posted a question that was actually not related to the problem. Anyway so the solution was following this tutorial here EXACTLY: Please note that I freaked out half way through and came here to ask for your help, meanwhile the above link fixed it - it was in startup recovery for 3 hours by the way! Thanks again. I work with Dells daily and you can typically see if the drive has failed via the on-board F12 diagnostic menu. I'm not sure if that works for this Dimension since it's older though. When you first see the Dell screen, hit F12 continually and see if it pulls up a boot mode menu with an option to select and run diagnostics.
The diagnostic tool will give you an error code on the hard drive if it has problems. Otherwise, you could only really tell with chkdsk errors or an error that the drive isn't detected at all.
