Windows 8.1 not booting : "Boot manager failed to find OS loader"
Hello all,
I know this question came up before, but I have being trying to fix this for many days now, without luck and I feel I need some new ideas...
The short story:
My Windows 8.1 is not booting, and gets trapped in cycle of Boot Manager until I tell the UEFI to boot from disk or USB
I can boot up from external CD or USB Windows RE, from which I can get to prompt line
In the log file in C:\Windows\System 32\LogFiles\Srt\SrtTrail.txt I read:
Boot manager failed to find OS loader
Repair Action File Repair à Failed (err code 0x4001)
Repair Action Boot Config Data Store Repair à Failed (err code 0x2)
4. My disk is GPT partitioned, with UEFI Bios
5. I tried the typical Bootrec commands: FixMbr, FixBoot, ScanOs, RebuildBCD but I always get the error:
Identified Windows install:0
6. I tried Bcdedit but I get:
the boot configuration data (BCD) store could not be opened
7. I tried to create a new BCD store in the FAT32 partition (temporarily named "v:\") with
bcdboot c:\Windows /l en-gb /s v: /f ALL
but I get:
Failure when attempted to copy boot files
8. Finally, I noticed that in
C:\Windows\System32\
I DO NOT have the file winload.efi
while in: ESP\EFI\Microsoft\Boot\
I DO have the file Bootmgfw.efi
One question I have is: Is it possible to copy a "healthy" winload.efi from somewhere in my PC into C:\Windows\System32\ ?
Where (which path) could I find it?
Any other ideas? Please help !!!!
Many thanks!! This is literarily driving me crazy because I really don't want to reinstall windows....

"Boot Manager failed to find OS loader" - Windows XP
Hello, I'm new in this community.
That being said, I have a problem with my Thinkpad SL410. Two nights ago I shut down my laptop. It was working fine at that point. I clicked on shut down, but I think it went to "update and shut down". BAD idea, since now, its stuck on a loop.
When I try and boot up the laptop, it only brings me to R&R4. Then, after it scans and tries to "fix" the problem, it gives me a message. Unfortunately, the message is in chinese since I bought this laptop in china, so with my rough translation skills, I was able to determine that "Boot Manager failed to find OS loader".
You would think that that would be easy to fix. I go grab a windows recovery ISO, and put it onto my bootable USB. Problem is, R&R is almost getting in the way of recovery console. When I boot from the usb, there is a black screen with the message "To boot rescue and recovery environment, press f11". I have tried to press f11 and I have tried to wait, but no matter what, it takes me to the thinkvantage rescue and recovery, as opposed to the windows console.
Essentially, I cannot access the console to type in:
-fixboot
-fixmbr
I have painstakingly translated much of the R&R page (The one that gives you 3 options; restore, backup, reset to factory settings). I don't think there is a way to get to recovery console via that rescue and recovery page. So I do what is most logical. I try and restore to a backup. Technology doesn't seem to like me because after waiting for 30 mins, its at 93% done and there is a message saying something along the lines of "C: doesnt have enough space".
Great. What other options do I have? I know the hard drive isn't corrupted and my files are still there, since going into "backup" shows me all the files (pictures, documents, etc...). I can't back them all up and factory reset since not only would it take forever, but it would take up wayy too many gigs of space, and I simply can't get my hands on a massive storage system atm.
This is very frustrating since I only started using this computer after my dell laptop had a hard drive failure. It's a pain trying to get through dell support, only to have my situation a whole lot more complicated since it was a gift from china, and already registered to someone. Then a perfectly good working computer fails on me again, and this time I can't analyze the problem correctly since the computer is in chinese.
TL;DR
"Boot manager failed to find OS loader error. When I try booting from Windows XP ISO, R&R gets in the way. I also can't do a restore to backup since my C drive apparently doesn't have enough space.Hi dizscez, welcome to the forums,
I can't promise, but something which has worked for me in similar situations is explained in the following KB article. Basically you would be doing the same as running a system restore to a previous point under Windows

I was running window 7 (64bit) on my Mac switched it off (14th April 2011) last night and it applied 11 updates,this morning it no longer works I get to the partition selection screen and it freezes. Any one know how to repair it if I can't access the windows side ?
When the message came up saying that this version of windows was incompatible... I tried 'cancel'. It moved on. It was in the middle of step 3 of 4 on the upgrade. It appears to be ok now. I'll let you know if I have any more trouble.

Windows Tablet workplace turn on device management failed on auto-discovery without any error
Hi
I am using windows surface pro 3 to test windows mdm function. I set up a CNAME for my test domain and pointed it to my develop desktop. My discovery service uses a publicly signed cert from VeriSign. If I turn off the auto detect server address switch and
input the discovery server manually, everything works well. But if I using the auto-discovery, the enrollment stopped before sending the discovery SOAP request.
Below is the network traffic between my tablet and my server:
step1: https to enterpriseenrollment.mydomain.com and failed for SSL certificate mismatch
step2: http to enterpriseenrollment.mydomain.com and get 302 redirect(my discovery service)
step3: https get to my discovery server and get HTTP 200.
Then the tablet does not send any request any more, it should send a HTTP get again with Content-Type: soap+xml and then a POST with soap but it not.
These work flow is as same as the Windows Intune and Intune works! I don't know why.
Thanks for any help!Yes, because if you are using the actual hostname in the manual address, something like
https://yourServer/..., and if the SSL Certificate is issued to "yourServer" (CN=yourServer), then there is no certificate name mismatch or SSL errors during certificate validation.
However, when the automatic enrollment happens and the HTTPS request is sent to
https://enterpriseenrollment.yourServer.com/..., then even though the underlying connection is made to yourServer IP Address, the certificate that the server presents is for yourServer, not enterpriseenrollment.yourServer.com.
So there will be a certificate name mismatch and the secure channel establishment will fail.
For this automatic scenario to work properly, the server certificate must be issued to the correct domain - such as a wildcard certificate (*.yourServer.com). That should ensure that there are no secure channel errors and then the enrollment process can
continue further.
You can use the manual address for development/testing purposes, but once you decide to release the solution, you may want to use the automatic discovery for easier end user interaction and use the right SSL certificates - issued to the right CN.

Adobe Application Manager failed during update and fils to reinstall
G'day All,
I put this up in November last year in a Creative Suites discussion thread (sse blow the line), and though the original post has been viewed more than 280 times, I have received no responses. I simply cannot update my CS6 software. I have just reposted the information below there, and figured I should try here, also.
Details : CS6 design and web premium, HP Pavilion quad-core i7, now running Windows 8.1
Essentially my application manager failed while it was upgrading itself as I was attempting to fix a problem with Acrobat/the Adobe PDF printer constantly failing after printing only one PDF. The updater/application manager then simply disappeared from my system altogether.
At the time of the original problem I had downloaded ApplicationManager7.0_all.exe; if I attempt to run it I get a pop-up window 2/3rds of the way through the installation and the following message 'Installer failed to initialise. Please download Adobe Support Advisor to detect the problem'.
Adobe Support Advisor no longer exists.
So I tried the latest version - ApplicationManager8.0_all.exe. This installed just fine, but seems to be entirely oriented around CC applications, so I haven't tried it on my CS6 programs. Should I just uninstall it? I rather wonder why it says 'This patch will install the Adobe Application Manager that is included with Adobe Creative Cloud, Adobe Creative Suite 6, Adobe Creative Suite 5.5 products' if, in fact, it's just for CC products.
So, any suggestions on what to do now? I'd really like to be able to update my applications via a Manager that will actually function.
regards,
Bill
G'day All,
(CS6 design and web premium, Windows 8. HP Pavilion quad-core i7)
Frankly, this is ridiculous.
Having been driven nuts by the 'Acrobat manager is not activated' message which persisted in popping up if I made any attempts beyond one to create a PDF - that is, I could print one, and then no others without a reboot, nor having done so could I read any PDFs - I searched online and got a discouraging, tangled mess of suggestions, including the fairly obvious one of checking that all programs had been updated by the Application Manager.
'Ah,' I thought, 'maybe if I ensure everything's up-to-date this thing where Acrobat failing to start because it thinks it's not 'activated' means I can neither read nor print PDFs will be miraculously fixed without my having to install magical patches or deregister and reregister the entire suite in order to appease a program I don't even use or want!'
Poor naive fool that I am!
So I tried to run the Application Manager.
It momentarily flashed a message claiming (I believe - it was only there for a second) another instance of itself was running, then proceeded to run an update process for the application itself, then threw up an administration window seeking to allow the program to modify the system about 2/3rds of the way through, and then announced via a little window with one of those horrible little red 'fail' symbols that the application manager had failed to install.
It sure had!
That's it - I now have no Application Manager to attempt to manage updates through! No shortcut - that disappeared too! Nothing in the hideous Windows 8 start menu! No search will reveal it! It's simply gone. Yes, I've rebooted.
All I can find online suggests installing a new instance of the Application Manager, which is, of course, the CC version, and I'm not a subscriber. OK, maybe that will work, but, quite frankly, with two strikes against Adobe already I'm going to ask if anyody actually knows whether this approach, or any other, is likely to solve the problem.
regards,
BillThanks for the reply, Jeff. Sure am! But that's not the main problem.
However, it appears the main problem has been fixed - via the installation of AAM 8 - a mere 9 months later! CS6 updates - woohoo!
This didn't fix the Adobe PDF printing thing - in fact, I just lost everything I'd previously typed in response to you testing this hadn't been fixed by AAM 8's updates (it hasn't!).
However, during the 9 month fallow period I've discovered that if I keep process explorer open and kill the splwow64.exe/acrotray.exe process tree after every single PDF printing I don't get bizarre messages telling me the Adobe PDF printer isn't 'activated' or have my system go into a tizzy and need rebooting. So it still doesn't really work, but I do have a work-around...

Bill -

RAID Fails to find the first device
Hello all.
This is my first post to the forum. I did a brief search but i couldn't find any good results, so i tought i'd post my prob here.
I have an MSI K7N2 Delta2-LSR motherboard, with a 450W PSU (i don't have any more info on that yet), 2x512MB RAM DDR 400 (no more info on that one yet either), 2x120GB SATA WD HD, 1xDVD TEAC, 1xDVD+-RW SONY DL, 1x1.44MB FDD, an ATI RADEON 9600 PRO ALL-IN-WONDER VGA card on an nForce chipset.
The first HD has WinXP installed on it with the raid drivers installed properly. The second HD has Mandrake 10.1 Linux installed on it. They are installed as separate arrays.
The problem I'm having is that while I'm working in Windows, after a while the computer completely freezes. The only possible way out of it is to reset the machine. After I do that, at the boot screen, it fails to find the first HD (the one with WinXP on it). If i turn it off for let's say 5 minutes, and boot up, it detects the HD again and goes on loading windows. After I log in i have at maximum 5 minutes before it freezes again.
It does this every time. The more time I leave my PC turned off, the longer time it will take to freeze again when I'm logged in WinXP. I formatted the HD many times, installing every possible combination of my drivers but the problerm persists. Although it has never happened anything like that in Linux.
Could it be the RAID Controller (onboard), the WD HDD, or the Motherboard in general?
What can I do to find out what the problem is? And if possible, how to solve it?
If more info is needed, I will update the info of my pc as soon as I get back home.
P.S. I cheched the WD HDD, using WD tools like Disk Diag, etc. It never gave me any problems. I also used UBCD for win, and cheked the disk, to dicover once again, that the disk supposingly has no problems.
Any help would be appreciated.
Thanks in advance.of its label Power Supply Guide

Hi there
Trying to patch a new Windows 7 SP1 image within SCCM 2012 SP1, but it's failing.
I've searched for information on the failure messages I am seeing, but although there is a LOT of information online concerning Offline Servicing failures, I can't find anything on the errors I am seeing.
I've tried injecting a single update, five updates and ten updates, no difference, same messages.
We have McAfee Access Protection disabled, as we know Offline Servicing simply won't work if this is running.
In the console, in Schedule Update Status for the image I am trying to update, the following message is shown:
"Failed to find or access the update binaries to be applied on the image."
That sounds as if the process can't find the actual .cab file for any update I've tried to inject, but I don't know why it wouldn't be able to do that, we have Software Updates configured and the .cab files are on the same server.
When I looked at the OfflineServicingMgr.log file, I see the following entries:

I'm not sure what file "Failed to find properties of file 4" is referring to, whether dism.exe, an update or the image itself, but immediately after this message appears the image is unmounted. After that this message shows:
"Completed processing image package PackageID. Status = Failed"
As I say, there's a lot of information available re Offline Servicing but I haven't found anything with these particular messages.
If anyone has encountered this before, I'd appreciate any information you have.
Regards,
John.Hi,
I think file named 'NO_SMS_ON_DRIVE.SMS’ might be causing this issue. If this file is present in logical drives, then please give it a shot one more time after deleting this file from the logical drives.
Due to this file, it might be preventing 'smsexec' service to skip the drive when looking for content. So worth a try!
After deleting this file, you also need to restart 'smsexec' service to reflect the changes. You can also verify from below registry value & ensure that all of your logical drives (specially where SCCMContentLib directory resides) should be listed
over there
'HKLM\Software\Microsoft\SMS\DP\ContentLibUsableDrives'
Hope this will help!

Windows 8 and ArchLinux dual-boot - Failed to open file: arch\boot\...
Hey!
I have a problem where I don't know how to configure the EFISTUB to boot ArchLinux along Windows 8. I have read the instructions on the wiki and tried for two days and the only thing I've come up with is copying some files into the /boot/efi/EFI/arch/ folder, and adding the entry into the UEFI boot menu. I can select it when Restarting Windows8 through the shift-restart thing and stuff but when it attempts to boot it says:
Failed to open file: arch\boot\archiso.img
I don't know how to set this up and fix it. I am so confused with everything right now due to the instructions on the wiki basically being "You can either do it this way, that way or any other way." but does not specifically expain how each works (at least so that I understand it fully) and what has to be done to complete these steps. Like, I need a complete tutorial from Start to Finish, to do this because I'm too nervous messing up my partitions. I have understood some parts thought and what I want is to be able to boot it from the EFISTUB instead of chain-booting like I usually do. I just don't know how to connect the entry in the list to the proper files to boot the system.
What I have done:
Installed the base system.
Istalled grub in the base system but has not used grub to install on the /boot yet because I don't know if it is to be used if I'm supposed to use the EFISTUB (I was thinking efibootmgr would be enough)
Tried to use efibootmgr to make the entry, but the entry does not work. (If this is how I should do it, can you explain which partition to target and what the different values would mean when answering?)
I don't know which one is right, or if both shall be done (I guess Grub is used if I want to chain-load. I guess I can do it if it's the only way)
Anyway, I hope you guys can answer me so I can fix this. ThanksWhat you're trying to do now is:
EFI->kernel (EFI stub)
This is appealingly direct, but it's tricky to get working. What the wiki now recommends is:
EFI->gummiboot->kernel (EFI stub)
...or...
EFI->GRUB->kernel
These approaches are less direct, but they're easier to configure. The trouble is that both the EFI's built-in boot manager and the EFI stub loader are tricky to configure. For a newbie to get them both configured correctly on a first attempt at installing Arch is very difficult. Getting the EFI to launch gummiboot or GRUB is easier because these programs don't require the complex parameters that the EFI stub loader requires. Those parameters can instead be specified in the gummiboot or GRUB configuration file, which is easier to manage for quite a few reasons.
If you want to pursue using the EFI stub loader directly, you certainly can. I've learned from experience, though, that it's not worth my time to try to help with users who want to do this. Using an intermediary program is easier to get working. IMHO, the direct approach has no real benefits except that it gives you bragging rights that you've done it. Your system won't boot any faster or more reliably in the more direct approach. (Well, technically it will be faster, by only by a matter of milliseconds, assuming you use a 0 timeout value in gummiboot.) In fact, it will be less reliable, because gummiboot, GRUB, and rEFInd all offer ways to adjust boot options on a boot-by-boot basis, which is very helpful when fixing problems. You can't do this with the direct approach. -

[SOLVED] Having trouble dual booting Windows: normal.mod not found
Hello every one, I'm a Gentoo user who wants to try something different. So I thought I'd install Arch on my new laptop.
Anyhow, this is my first proper UEFI install on real hardware. So I might be doing something stupid here, but I've searched all over the forums and the internet and can't seem to find anything similar about it. So please excuse me if there is already a similar or very similar topic
Since I'm new to Arch I followed the Beginner's guide. Everything went fine, install was very quick compared to Gentoo phew... anyhow there came the tricky part, the bootloader install, as I am a real total noob with EFI. I followed the instructions carefully.
The result is: I now have 4 entries in my GRUB menu, 2 are Arch and its fallback, one is Windows 8 detected by osprober, and one is my custom Windows 8 with the usual chain loading setup that i've always used (with some fixes found on the 'net). Arch boots fine, but Windows doesn't; I get booted down to the recovery console, with an error that GRUB cannot find /boot/grub/x86_64-efi/normal.mod. Even though the file is of course existing. I tried to "insmod part_gpt" and others, and it couldn't find any of them, except part_msdos. Yeah I know, it's weird. Unfortunately I need to use Windows sometimes for some programs like Guitar Rig which need a good native audio connection.
My opinion is that there must be some place where the paths are not correct. But I keep looking at the config files and I can't find anything wrong with them...
The system had a Linux Mint 14 install on it previously but it bricked itself while updating to Mint 15. And I only really had Mint on there because of the automatic bootloader setup. Which worked well up to when I got rid of Mint (it was on /dev/sda8, where Arch is now). I hope it doesn't complicate the matter.
My EFI system partition is /dev/sda2. There are so many partitions because it's a Samsung laptop and there's a partition for samsung recovery, one for windows 8 recovery, and so on... The only "real" partitions are /dev/sda2 for EFI, /dev/sda4 for Windows, and /dev/sda8 for Arch.
Here are some command outputs to show you what my system is like. I hope they are helpful. If there's anything missing I shall supplement it of course!
Thanks in advance

Thanks for your reply!
Yes, I had /dev/sda2, my EFI partition, mounted at /boot when I did grub-install and grub-mkconfig. I also had the efivars filesystem unmounted, and ran rmmod plus modprobe on efivars as written.
umount /sys/firmware/efi/efivars
# modprobe -r efivars
# modprobe efivars
My command was exactly the same as the beginner's guide, and it was
grub-install --efi-directory=/boot --bootloader-id=arch_grub --recheck
Now looking at that command, I am wondering, should it have been "--efi-directory=/boot/EFI" or something similar like that? But the fact that Arch boots and runs fine kind of shows the bootloader did indeed install correctly... Or partially at least.
Maybe an ls -l of some of my /boot directories might be useful. Thanks!

i have macbook pro 13.3 inch. I am installing window 7 in boot camp manager after copying file of window upto 67% it doesn't response and i had forcely shotdown my macbook. Now my macbook doesn't open and stop in black screen with cursor blinking. Now how could i open my macbook pro.
At startup hold down the Option/Alt key and from the screen that comes up select your OS X partition to start the computer from. Then use the Boot Camp Assistant app to Remove Windows and the partition you reated for it and it will Automatically place the space you allocated for the Windows install back into the OS X partition.
NOTE:
Do NOT use Disk Utility to erase the partition that was created for the Windows install. Use the Boot Camp Assistant app again to do that. -
i was installing windows 8 on mac by boot camp and after i put the windows code and choose the partition i formatted the boot camp sector it said windows can not install on this sector because it is gpt
Reinstalling Mavericks depends on several factors:
if you erased your recovery partition
what OS originally came on your Mac.
I'll assume you don't have a backup available that you made before your mishap, because you didn't mention it.
That's really the take home message here: have a backup!
If you still have your recovery partition:
boot into the recovery partition (command R at restart)
use the recovery partition to reinstall Mavericks. see: OS X: About OS X Recovery
if you do not still have your recovery partition, then it depends on whether your Mac originally came with installer disks or not.
If it originally came with installer disks, you would boot from the installer disks, erase your HD, and then reinstall the OS that is on the installer disks, and then upgrade as necessary until you get to Mavericks.
If your mac did not originally come with installer disks, but you managed to erase your recovery partition, then you can try to boot into internet recovery (option-command-R at restart), and use internet recovery to erase your HD and reinstall the OS that originally came with your computer, and then upgrade to Mavericks if you need to. See: Hands on with Mountain Lion's OS X Recovery and Internet Recovery | Macworld
(the reference refers to ML but it applies just as well to Mavericks). -
Under Windows 7 Ultimate x64 and Boot Camp, my 27 inch Apple LED Cinema Display checks out as a Generic PnP Monitor and is shown as NOT HDCP compliant. I haven't been able to find any kind of an .inf file to use. Does anyone have a solution? Or is Apple's implementation of HDCP (if it's there) incomplete?
I am having this same issue. Im not sure if this is the cause but I think this is keeping PowerDVD Ultra 11 from playing back Bluray under Windows 7 / Bootcamp
