MBR Error 1 On Boot - Windows 7 (32-bit)/XP SP3 Dual Boot
Nov 9, 2012
I have a laptop I bought a year ago on which a created a dual boot Win 7 (32bit)/Win XP SP3 install, each on a separate partition. It was my first Win 7/XP dual boot install, and my first personal system that I allowed to have a Win 7 install on it at all, so although I have plenty of experience working on pretty much every previous version of Windows, I have very little experience with Win 7 and dual boot configs.
Today about 2 hours ago my audio spontaneously stopped worked for no good reason, so after shutting down each program to see if that cured it (which it didn't), I restarted the system. Out of the blue, for the first time I've ever experienced it, I received the msg "MBR Error 1" - Press any key to boot from floppy. I don't have a floppy of course on my laptop, and if I press any key I simply get the same msg. I turned the system off for a few minutes to make sure it was a good cold boot, but every time I still get the same msg. I tried switching the BIOS setting from IDE to AHCI (IDE is required for XP to boot, AHCI required for Win 7), but I still get the same error msg before I'm even prompted with the OS boot selection, so it made no difference of course.
I looked up this issue and found various suggestions, but none of the ones I found took into consideration a dual boot config., they were all Win 7 specific solutions. I don't what to try and repair the MBR only to have it screw up my dual boot config and be unable to access XP, which is what I use almost exclusively, nor do i want to lose access to Win 7 if at all possible.
I had a backup HD of my complete system that I saved several months ago when I upgraded my HD, and I periodically refresh the most important files on it, so I'm currently running on the laptop in question using my old HD, and it's working just fine. Worst case I can just clone my old HD to my newer HD that's screwed up, but I'll still lose a lot of changes I've made to the OS since I upgraded the HD and have to reinstall and config a number of programs, so that's my last option. I'll also have to back up about 200GB of data from the newer HD which is much larger than my old HD, and then restore it back after the clone, something that will take a lot of time and unncessary effort if I can just fix the MBR.

I'm having a problem every time I power on the system. I'm dual booting vista ultimate with win 7 build 7100; with vista I have no problem, but with 7 every time I start the system the first boot attempt gives me the error 0xc000000e after the boot manager display: "the boot selection failed because a required device is inaccessible".;after a reset the system boots 7 with no problems. Win 7 is installed in a brand new hd(seagate barracuda 1.5tb) and vista on a second hd.
I've search the web for people with a similar problem with no success. I've tryed already many solutions but the problem persists(latest bios for the motherboard, latest intel sata drivers, etc). I'm hoping that this could be a bug in win 7 instead of a hardware failure for the hd. Again, the strange thing is that this only happen after the power on. After that first error, no matter how many reboots, the system always boot without problems.

When I go to create the new partition in Windows 7 that I want to install XP on it creates it as a logical drive. How do I create a primary partition instead?

I have a Windows 7 installation (x64). I wanted to install windows xp 32 in a dual boot scenario for some backwards compatibility hardware issues (video stuff).Anyway, I read the various tutorials and I have used nlite to put sata drivers into my win xp install iso/cd.My problem is that windows xp won't I get the hard drive error message DURING the install (ie, the first time xp asks you to reboot, but long before it tries its various installation things) have tried the various things associated with this, Easybsd, a Windows 7 restore and using fixmbr/etc. I can get BACK into windows 7, but setting up the menu is pointless because xp never installs correctly to begin with. It seems that the guides on fixing this error message are assuming you get it after xp completes its install and tries to boot -- instead, I am getting the error DURING the install. I get a /windows directory on my partition, but it clearly isn't a complete install because I never see the windows install screens with the pictures, estimated time, etc.

same problem as 4 weeks before. Dual Boot Windwos 7 and Xp. Windows 7 was installed first but today i install fresh original Windows 7 copy... Windows Xp (partiton F NTLDR error.
I'm not sure if must be NTLDR, NTDETECT and boot.ini at C: with Windows 7 or F: with Xp.
Sure, hide files are opened but still no files in C. There is only bootmgr.
I'll try copy files NTLDR and NTDETECT from WinXp CD at disc with Windows Xp... nothing happend.
What i need to do?

I installed opensuse 12.1 on dual boot along with my other windows 7 installation. Installation of opensuse is successful and i can use it. But when I tried to use windows 7 on grub, it says bootmgr is missing. I've already encountered this problem a long time ago so i tried to use bootrec /fixmbr, bootrec /rebuildbcd and bootrec /fixboot in the recovery console in the windows 7 DVD. Rebuildbcd and fixboot did not work and it said something like it cannot find my windows installation. I also tried bootrec /scanos, it returned a windows installation on D:\Windows but my windows is in drive C. I think this has something to do with me messing up the active partition in disk management a month ago but i already fixed it by setting the active partition to the system reserved partition. Only fixmbr is successful, but now i can't boot on any OS because it says: Missing operating system.I also tried bcdboot C:\Windows but it failed with a message that goes like: Failure when attempting to copy boot information..

I can't get Win 7 to boot after setting up dual boot (Ubuntu 10.10) on my GF's laptop. I'll describe the problem and everything that has been tried so far. REALLY hoping somebody has an idea, I'm getting desperate.I installed Ubuntu last night via the Live CD. Used the Live version to install alongside Windows and partition the drive, install Grub, etc. At reboot, after POST it would just go to a black screen with a flashing cursor. I could only run off the live CD. A forum member determined the Grub was trying to load from the wrong partition. We changed that and voila! Grub now loads properly. I can boot into Ubunto via Grub with zero problems. HOWEVER: when I try to boot into Win 7 from Grub, it just locks at the same flashing cursor of death screen. The 7 partition is till intact, I can see and access all the files on the 7 partition from within Ubuntu, however 7 will not boot. I have tried downloading and burning the Win 7 repair disk and doing all of the following,Running the automatic Start Up Repair - several times. All it does is remove Grub, but booting still goes to the flashing cursor and I have to reinstall Grub again to be able to do anything after POST.I have used the command prompt to run "bootsect /nt60 SYS /mbr". Has the same effect as above.I have used all the bootsec.exe /fixmbr, /fixboot, and /rebuildBCD commands. Again, all have the same effect and I have to reinstall Grub to get anywhere.I don't have an installation disk to try and just do a repair install because Asus apparently doesn't feel that I would need one of these. All I have is the recovery disks from the Asus AIRecovery application that want to just re-format the entire drive and start over. This isn't an option. It's my GF's laptop (mine gave up the ghost last week) and we both have WAY too much highly important data on here. Not to mention she would castrate me . Now from all my research the only other thing I've come across that sounds possible is that the boot flag needs to be set to a different partition. Somebody had a somewhat similar problem and it turned out the way Dell set up the system the boot flag had to be moved to a recovery partition and it worked fine. I'm wondering if Asus has something similar going on, but I can't figure out how to move the boot flag. I'm going on 12 straight hours of working on this now

I installed Windows 7 64bit onto RAID 0+1 and XP on separate SATA drive. However, I now realise I re-formatted XP drive "out of sequence" in so much as I didn't follow the correct procedure to alter the boot sequence prior to re-format.
I can no longer boot into Windows 7, see following
The bios recognises the RAID setup - apologies for the poor quality.
I have tried running the startup & repair via install DVD, several times, but I keep getting the messsage that setup & repair did not detect any problems.

I have 3 hdd's.
1 x 160GB (SATA)
- Partition: ~149GB - Win Vista64
1 x 300GB (SATA)
- Partition: ~220GB - MISC
- Partition: ~58.5GB - Windows 7 64
1x 1TB (SATA)
- Partition: ~931GB - Games
I ended up taking my 300GB drive, created a logical partition, then booted into the Windows 7 dvd I have. (win 7 - 7100?, straight off ms)
Firstly, it takes about a couple minutes just to load the files. Then once it finally gets to the splash* screen and the cursor appears.....it takes about 5-10minutes for the "install" window to appear which seems VERY odd since my machine is VERY fast. It takes quite a bit of time to accomplish installing from loading to finished (40minutes maybe)...
After everything installs when I go to choose the Windows 7 option on the boot menu, I get this black SOD
Windowssystem32winloader.exe error 0xc000000D
Something about the file being missing or corrupt.
I took my Windows 7 disk, and entered command prompt through recovery tools (which takes at least 5 minutes due to loading time to get to each time).
I ran DISKPART, then did LIST VOL, so it would tell me the partitions and letters.
Then I took another window, and entered bcdedit. The letters matched up with the partition letters and the file DOES exist.
I've tried 3 different sources on 3 different DVD's to see if perhaps I had a bad image (1 x microsoft/2 x torrent), but that's not the case.
I've tried setting the path's again through bcdedit to make sure there was no data corruption in the settings, and that was not successful either...
So when I need to figure is out why it tells me the file "winloader.exe" is missing or corrupt, when in fact it is pointing to the right harddrive, on the right partition, on the right location.
Yes, they all show up on the BIOS post, yes it recognizes the 300GB drive in the setup without extra drivers. The only hdd it needs extra drivers for to see is my 1TB, but I'm not using that for the Windows 7 installation.

I have installed a year before UBUNTU on my pc with dual boot (i.e. use either window 7 or ubuntu).the NTFS partition that contains the UBUNTU was corrupted and i wanted to take the dual boot from my PC. I used the instructions from the web site: http://www.makeuseof.com/tag/how-to-...t-environment/but the disk management tool would not let me delete the NTFS partition.Could any one help me delete the NTFS partition and use just windows 7 as the only boot. step by step help would be great.

I got windows 7 running fine for a while now and ever since my XP did not boot anymore.I was not worried to much about it since i did not need it at the time.But now i really REALY need it,See i got all my Cubase projects in there and my cubase plug-ins al setup in XP and i need to get to the projects?At first it did not do anything and using easyBCD did not help either.I cpoied ntldr and detect to the root of C: wich contains my XP and now it shows the bootscreen but hangs on a black screen.The thing is right before the bootscreen shows i see the text" invalid boot.ini" flashing by very quick.I am able to enter that winXP install in safe mode and i tried safe/vga mode as well wich works but thats all.

I had Win XP on 1 HDD & installed Win 7 on a different HDD. I think I accidentally did a dual boot install because Win 7 won't boot without the the XP disk connected to the motherboard.
That was fine until my XP drive died yesterday. Now Win 7 won't boot. The first time I tried to repair, Win 7 was not even seen. so I booted into diskpart and made the partition active. Now it could be seen as an OS.
Then I did a startup repair. It did whatever it does & when it was finished I restarted the pc but it didn't boot I went back to diskpart and confirmed the partition was active. I went back startup repair and tried again.
This time it said it could not detect a problem, but it still will not boot. What else can I do? My pc is homebuilt. Right now I have the 1 sata drive, 2.53 ghz cpu, 4gb ram, onboard video & sound

Just today I decided to download the Windows 8 consumer preview and setup my PC to dual boot with it.I am running Windows 7 home premium 64bit and the 64 bit windows 8 on my other partition. After setting up a separate partition on my hard drive and loading windows8 to this partition, I was all up and running. I had no problems setting up or running windows 8, the problem came when I booted back to windows 7 for the first time. When I booted into windows 7, I was getting the "unable to identify network" error, and no network connectivity.
First thing I tried was simply disable/enabling my network adapter thinking it was just some hiccup. No luck there. Next I pulled the power from my router, and let it completely reboot. Still no luck. I then shut down my pc and booted back into windows 8 and sure enough I am able to get internet connectivity when I am running windows 8. This got me to thinking that when I loaded windows 8 there may be some new drivers installed for my network card that are somehow causing issues when I load into windows 7 again. Not sure how this is possible.
I was under the understanding that when I loaded Win8 to the separate partition that it would keep all it's drivers and settings there and not effect anything when I was loaded back on windows 7 (This logic could be completely wrong, I don't know). So I rebooted and loaded back into windows 7, went into device manager and uninstalled both network adapters and drivers, and rebooted into windows 7 again so it could re-discover and setup the network cards with default windows 7 drivers. This did not work either and I am still getting the same error.

I have XP (x86) installed on one partition.
Last night I installed Windows 7 (x64) on a separate partition.
Anytime I had tried this in the past, using Vista, it always detected the Windows XP partition, and gave me a boot menu with "Earlier Version of Windows" option to boot to.
This is not so with Windows 7.
How can I get the boot menu to show both options, to boot to XP or to Windows 7?

I setup an XP/Windows 7 dual boot on two drives. Currently C: Windows 7, D:XP
Love Windows 7 and now I'm ready to convert to single boot Windows 7.
I'm not real savy re. bcdedit so will need very detailed instructions
I did find the command line in Windows 7 by going through accessories but I'm scared to go further without help.
Eventually I want to clean up the D:xp and use it for storage etc.
I'm guessing this procedure may have already be written up but I can't seem to find it.

I recently added a hard drive to my computer (SSD), and installed Windows 7 x64 onto it. The result being a dual boot system, which by default boots to the SSD, and optionally (by Windows Boot Menu), can be booted to the original drive (standard mechanical drive).
Initial setup went fine, however I decided to customize the Windows Boot Menu, so that logical names could be associated with each operating system instance. To do this I used EasyBCD and I altered the names in the Windows Boot Menu from: Quote:
Windows 7
Windows 7
to... Quote:
Windows 7 - SSD
Windows 7 - Standard Drive
Shortly after the modification I noticed that I was no longer able to boot into the original OS. Instead I was being presented with a "Repair Windows" option. Figuring that my EasyBCD "tampering" may have had something to do with the issue I decided to change the names back to "Windows 7" in the Windows Boot Menu. However doing so had no positive impact on boot up of the original OS.
After booting again into the original OS I accepted the "Repair Windows" option, and then left the computer over night to do it's "thing". After completion of the "Repair" the situation has deteriorated -
* Windows doesn't load (the same as before)
* Windows doesn't present a "Repair Windows" option (it did before)
* The computer reboots a short period after the "Starting Windows" screen is presented
As a side note the drive is in good health, and all data on it can be read from within Windows 7 when I boot to the SSD OS.

I had Win XP and Vista set up as dual boot. I have back up images of both using Norton Ghost. I then upgraded the Vista partition with Windows 7 RC and all was fine for several months. Last week I had issues with the XP installation and the only resolution was to put the xp image back on the xp partition. This action has left me with a boot screen with XP and Vista on it and as expected only XP can be booted.
I put the Windows 7 installation disk back in and it recognised the boot screen error and fixed it; (too good to be true I thought!) When booting, I got the choice of XP or Windows 7, so the Vista option had been replaced ) however, there is an error that cannot be fixed and so the boot fails. The PC does the usual reporting to MS looking for a solution but can't find one.
So, will I have to replace the Windows 7 partition with the Vista image and then reinstall the Windows 7 or can I recover this another way? Also, what is the best way to image, individually, OSes, so that the boot screen doesn't get changed?

When my computer wouldn't turn on in the morning I did the usual diagnostics; unplug things one at time test with spare components etc... Any way I qucikly figured out the PSU was dead so I ordered a new one and was back up and running. However when I reassembled the computer after unplugging everything (and removing the m/b) I plugged the HDDs back into different SATA ports from which they orginally came. When I came to boot the computer up I got the error message: 'BOOTMGR missing' or it may have been 'NTLDR missing' I can't remember.
I fixed this problem by using the 7 startup repair utility. I have no problem booting into Windows 7, but I have lost the option to boot into my XP install on anther disk. I looked in the boot tab under System Configuration and the only OS showing is this Windows 7 install. So my question is this: how can I get the choice of which OS to boot back?
(I should mention that the XP install is on a different disk from the 7 install).
