Boot Manager Failed To Find OS Loader - Startup Repair Giving Errors
Oct 5, 2011
I am currently using windows 7 ultimate x64. I was in the middle of a process restoring my computer to a few days back and suddenly it froze. I did a power shut down and when I turned it back on, I wasn't able to get back into windows. I was brought to startup repair and it gave me errors. 'Boot manager failed to find OS loader'. There was options for restoring, but all my restore points were gone. Recovery wasn't able to find image backup.
"Startup repair cannot repair this computer automatically". I was told to go into safe mode to restore, but whenever I enter safe mode, startup repair would take over and shows the same errors, also I read a tutorial using a repair disc ( made a copy of it on someone elses ultimate x64 computer) and I get the 0x00000e9 error if i boot from disc. What can I do? As of now I don't have the installation disc with me. I wont be able to get hold of it until tomorrow. There's a lot of important files in that hard drive and I really cant lose any.

My OS is Windows 7 Ultimate x64 and its boot by vhd.
One day, it failed to go to Windows and stuck at Startup Repair. I think it was caused by invalid driver.
But anyway, my concern is the Startup repair is unable to repair a Windows that is installed in a vhd. Then what should I gonna to do?

Basically the issue is that my computer won't boot. I have had it for just over a year and have never had any issues with it. It's protected and isn't used for anything dodgy, my brother uses it for SWTOR and I use it mostly for uni work and a bit of gaming here and there. Anyway out of nowhere it failed to start. Its done this once before and last time I just told it start Windows normally and everything was fine. This time not so much.
It loads up Startup Repair even if I select start Windows normally as it fails to do so and restarts itself automatically. I left it to detect errors but when I checked it a few hours later it still said searching so I cancelled and left it. I tried again yesterday and have left it on for approximately 25 hours to no avail, it still says searching! I have a lot of stuff I haven't backed up so I want to save it. Also note that there are no pieces of hardware plugged into the machine at all, only the mouse, keyboard and monitor.
Basic Info :-
Acer
Windows 7 x64
8 GB Ram
500GB HDD
NVIDIA G Force 950

Recently my Acer PC has had the Blue Screen of Death. Now when I boot the pc it goes straight into Startup Repair. The first time it did this it did not find a solution but I was able to go to a backup and when it restarted I was able to successfully load. I then started transferring files to my usb. As I was transferring a lot of my files, I can't remember if I got another BLOF or it just restarted but ever since then it just boots straight into Startup Repair, which cannot find a solution, but I have used my backups already so I don't have any more backups to go to.[CODE]

I had a dual boot with Windows 7 and Win8. I wanted to remove Win8 cause I was bored and didn't need it. I did everything right.
Dual Boot - Delete OS
But the boot manager failed. When I restarted I got an error saying that their is some invalid information. I didn't have the Win 7 disc, so I put the Win 8 disc and installed it in the partition that had win 8 before, hoping that it would recognized Win 7. But hasn't. So now I have a partition of Win 7 but it is not getting recognized.

A few days ago, I went to turn on my computer and it just gave me a black screen after the "Starting Windows" screen. I attempted to use System Repair, which failed. It said there was an unspecified error possibly caused by a change in system configuration. I have not changed anything on my computer, for the record, between the last time it worked and now. My husband said it downloaded updates, which would explain why it was off in the first place instead of just being on stand-by. Anyway, I then tried System Restore, which also failed. I can get it to start in Safe Mode with Networking, but it seems that everything I try to run to figure out what the problem is, is saying it can't find the problem. I enabled bootlogging and found this...

Living is south FL can be a bitch when the rains come as there often is a ton of accompanying lightening that plays havoc with the electrical system, even though I have surge protectors inside and outside the house. We just had some very heavy rains with lightening and my computer shut down several times, but I could restart it each time...except for the last time when Windows wouldn't startup. At that point, Start Up Repair came into play. Although I routinely backup on an external drive, of course I never did it this month-DUH!Results from SUR were error free (error code=0x0) on all the parameters tested, however there were the following error codes reported:"Unspecified change to the system configuration might have caused the problem." Failed: 0x1fRepair Action: System FilesFailed: x490There were more options to select for a recovery task, but I didn't try them as they didn't seem to be as salient as the two above.

Ok. So when i installed Windows 7 i also had the evaluation copy of Windows 7 on another drive. Everytime i boot the computer it asked me which copy of windows i want to boot to. I erased that driver so i could get rid of that problem but its still there. Even if i try to boot into that drive it errors out and restarts. I want to boot my computer and it boot strait to my ONLY os.

I had XP with '03 media center edition. I installed Windows 7 over XP, so I was not expecting that every time I now turn on Windows 7 computer I always get the windows boot manager and have to choose Windows 7 to continue booting up. Is there a way to fix that so it does not come up anymore and just starts up on its own. I realize that even if I do not click it, it is already highlighted and will start up on its own after the countdown is done, but I was wanting to know if there was a way to fix that altogether.
Should also mention that on msconfig and boot menu, the only one listed is the Windows 7 OS system and is default.

Hardware Information (This is from memory and may not be completely accurate):The computer model is emachines The processor is a dual core Intel Pentium The graphics card is NVIDIA (Can't remember the model.)4GB of RAM installed Software Information (Also from memory, but this is likely to be more accurate than the hardware.): Windows 7 Home Premium 64bit Antivirus software is Comodo Internet Security - Also the firewall (product information).I often used Advanced System Care for optimization.-product information.after searching the internet for ways to fix my problem for the past three days, I'm at a complete loss. I was told by a professional that my registry was likely corrupted and that my best bet would be to re-install Windows entirely. I was hoping it wouldn't come to that, but was prepared nonetheless.So I inserted the installation disk, and wouldn't you know it, the installer wouldn't recognize my hard drive (BIOS recognizes it though). Searching for reasons why this was happening only turned up people saying to make sure it was recognized by BIOS, which I considered a no brainier. When it still didn't work for people in certain threads, they were told to try wiping their hard drives. I've done it. Windows still doesn't want to notice my hard drive.After that, I decided to try and install Windows to an external hard drive. I know this isn't how Windows was designed, and I knew it wasn't how Windows was meant to be used, but I was (to my knowledge) out of other options (Also, the external hard drive has 1 TB of space on it, so I wasn't concerned about speed loss). So, I searched for ways to do that, and I came across PWboot. The first half of the installation worked, the second half did not. I began getting an error that read (bootmgr is missing press ctrlalt+delete to reboot.) Which I did. But that didn't fix anything. So I tried the entire process again, and it didn't work.The "Repair your computer" feature in the windows install disk turned up nothing as well. I can't "Factory Reset" because it can't detect any installation of windows, the startup repair function can't "repair this computer automatically", and none of the other options will even open (with the exception of the command prompt, but most of the commands aren't valid for some reason.)

On boot it is taking him to the windows 7 startup repair which fails with StartUpRepairOflline AutoFailover CorruptFile
I have suggested the following, all which have failed to make a difference:
bootrec.exe with /fixmbr /fixboot and /RebuildBcd
Run chkdsk
Startup repair
System Restore - two dates tried
The pc is about a month or so old, and I'm thinking it could be a hardware issue, hard drive?
Two things I am going to try when I get there is a WD Diagnostics on the Hard drive, and the sfc

I've been having trouble trying to get my computer to boot; I'd noticed a drop in performance (still unsure why) so decided to boot up in safe mode and poke around - it was not my original intention to install AC 5.3.0 but somehow it happened. I ran the 'deep-care' utility and everything was working fine, my computer rebooted and performed a disk check: there weren't any errors that I can remember apart from [something along the lines of] 60 reparse files. Following this my computer restarted and Windows failed to load, restarting to show me startup repair - this isn't the first time this has happened, a similar thing occurred following previous attempts at boosting speed, though before I was able to get Windows up and running using an Ubuntu installation disk... still don't understand why - no need to say that it didn't work this time. Startup repair refuses to work and my system restore points have vanished; I would try doing a repair install if I had a copy of the disk. I built the computer myself a few months back, borrowing a Windows 7 installation disk from a friend (who has now conveniently lost said disk), startup repair does tell me something about 'Problem Signatures'.

Recently my computer has been randomly just giving me the BSOD. Normally this problem was resolved by a simple restart but tonight about an hour before I posted this, the blue screen sent me back to startup but instead of giving me the usual "Security mode" and Regular Startup. It gave me Startup Repair and normal startup. After clicking normal startup just to see if it would correct itself like normal,my pc instantly BSOD'd, bringing me back to my two options. I've been sitting here staring at the startup repair screen for about an hour now.

I used windows update and updated my nividia 9600 drivers and now for the past couple days I have been unable to reach my desktop. It boots to startup repair and does a short scan then finally says it was unable to help will either shut down, restart or scan again. I've DL'd a vista repair to restore but it doesn't have any restore points and I was able to get onto a DE language linux version of my computer but haven't been able to fix it there, partly cus i cant read most of what im seeing.

I get into startup repair everytime i boot my pc which is never successful. I am definitely goin to explain it in detail but dis is basic problem nd plz dont mind typing coz m typing fast on iphone which may cause errors in typing!Yesterday,i used my pc for 7-8 hrs continuosly which is not big deal but due to it i can't figure out my action which caused problem. I kept it on for downloading at night nd when in morning i got boot screen which comes when pc is directly turned off. I did Start Windows Normally nd i got usual windows 7 loading animation for a secong nd den it started startup repair after that everytime i boot it takes me to startup repair resulting in continuos failure. I hv googled nd found many threads but none matched my exact one. Startup infinity loop didn't work. Below r given few conclusions nd obstacles-1.) i can't get into advanced boot options using F8. But i can get into recovery menu using install dvd nd view advanced options frm startup repair.
2.) System restore din't work. I mean its not successful in restoring.3.) bootrec.exe didnt work4.) imp point to be noted is my last update was on 23 dec while pc worked fine on 24 th & 25th dec means dont knw wat happened 25th night that caused this problem on 26th morning.5.) sfc/scannow says "a startup repair is left to be completed." it says to complete that first then use sfc/scannow.6.) chkdsk results in last line saying failed to transfer log......7.) i also get a report like many others about that problem signature.8.) repair install not possible coz windows can't start only.9.)i hv made a backup using cmd but is there any way without clean install?

So yesterday I added another hard drive to my computer. I now have 2 SATA hard drives running in my machine. I used the disk managment, and the 2nd hard drive is working as it should.
However, when I shut down my computer and turned it back on, Windows will boot to the Startup Repair screen every time. I checked the BIOS and made sure the boot order was correct, and even took the 2nd hard drive off the boot order in order to make sure it wasn't causing any issues. It's pretty annoying, because every time I start up, I have to wait for the whole repair process before it will load normally. Each time it always says that there are no repairs that could be made.
I also am not able to put my computer in sleep mode any longer. I believe my BIOS setting is set to S1, and before I never had any problems. I would put my comp to sleep and everything would be fine. After the 2nd hard drive, my monitor will turn off and it sounds like 1 of the hard drives turns off, but the CPU and fan are still running and it does not completely go to sleep.

I've got two hard drives with Windows 7 on it. One of them, the operating system crashed entirely, on the other, it's a perfect copy of how the other hard drive was at factory settings (drivers and all). Now, you're probably wondering, hey, why not use the other hard drive? Thing is, I'm trying to save / keep all the programs on the first hard drive in order to save myself the hassle from 1) pretending I'll find / looking for the disks that I know I don't have and 2) the time it'd take to install them.the machine was *not* giving me anything except sending me over to start up repair, stating that it couldn't fix the problem. I used the other hard drive to boot into Windows, and was hoping to do a repair option on the other hard drive. Unfortunately, I don't think that's entirely possible. I used Hirens Boot CD to check out the System32 / Syswow64 folders, and there was hardly anything in there. So, naturally, started copying off certain sub folders from one to the other. Now, I can get it to attempt to boot / it sees the partition / I go to safe mode, and it hits Classpnp.sys for a split second, then startup repair. Startup repair let's me see that there is one root cause, but, after doing its thing, says that it didn't detect an issue with the startup.
1x Sony Vaio laptop 2x Hard drives (one with a factory restored image on it, another one that won't boot into the OS)The hard drive that I need to boot from / one that has my programs goes to Startup Repair after hitting Classpnp.sys in Safe Mode Startup repair has one thing fail (StartupRepairOffline issue), but says it didn't detect a problem / everything booted fine afterwards Attempted to rebuild the BCD (after successful fixmbr / fixboot), but it states it sees 0 installations of windows. However, I have a Windows 7 retail disk that sees the installation folder.

I have searched on this forum and Google to see if others are having the same issue. After updating Windows last week, my computer has been in a consistent state of decline. Today, I powered the CPU down and it will not start-up again. I have attempted to use the windows repair disc, but am now told that startup repair cannot fix my problem.

I cleaned the dust from the comp & since then I am getting this error, sound is only working on front 2 speakers. i ensured the card is properly installed, which it is. Last 4 months its been working fine with 4.1 speakers.
Now I cant start the EAX control setting.
I uninstalled the card & drivers & cleaned the registry then reinstalled the drivers from CD.
On installation of the drivers & sound it detects by old speakers as stereo only but all 4 speakers give sound which is too bad, I can now use the EAX control settings .
then I run the windows update it download a creative driver which when installed does show me 4.1 speakers but now the EAX control panel wont open & gives error.
"the audio device supported by this application is not detected. The application will exit"
any clue what went wrong & how can I get this working?
