I upgraded to Windows 10 from Windows 7 and everthing installed without problems exept when I start or restart with a usb flash drive inserted, I get "Boot manager is missing". If I remove the flash drive and select Control-Alt-Delete windows starts with no problems.I realize the Windows trying to boot to the usb and fails.

My situation is that after a recent issue with my user profile going "missing" (I think) I thought do, do you know what I'll just reset my system and start over. But windows 10 would not reset. Instead I grabbed the windows 7 disk to reset that later hoping to install windows 10.
I was having problems with my Kingston SSD so I installed it onto my HDD and later on tried to clone the HDD to the SSD and then format the HDD so the OS ran off the SSD. I have clone the 2 drives but haven't formatted the HDD. I tried booting the SSD but it comes up with the BOOTMGR IS MISSING! I find a solution which is to reset the bootmgr using the code "Bootrec.exe /rebuildcd" but I can type the command in due to not being able to access the system repair.
This system repair issue says that the disk is not compatible meaning I cannot enter to the other options to get to the Command Prompt.
My windows is not booting the m.2 ssd. I bought a new laptop with a hdd. Bought m.2 850 evo ssd and installed it.Installed windows 10 on it without removing the hdd. It was loading fine but i noticed that the boot loads the previous hdd before continuing to the ssd. Tried deleting the hdd from msconfig boot and that didnt work.
Still in the bios i only saw "windows boot manager HDD" under the uefi bbs boot priorities. But it recognized the ssd in storage information. All that and i even tried cleaning with diskpart the hdd ( the big mistake ).So i now got no boot manager now. And ssd is not loading. Is there a way to fix it without reinstalling windows ?
Migrated OS 8.1 from HDD to SSD . Migration software installed command line in bios "Boot Manager on Disk 1". If I do a format of SSD will bios revert to original without the reference to disk 1. I intend on doing a clean install of Windows 10 retail version in UEFI mode....
View 2 RepliesWhen I updated my computer from windows 7 to windows 10, all of a sudden I don't seem to have a CD/DVD drive anymore. It shows up in the BIOS but not on the actual computer. I have tried to make sure the computers all plugged in correctly and it is. So what can I do to resolve this issue, and if there are so many problems with windows 10 why on earth allow have of the entire population download, especially when MICROSOFT should have thought of all the bugs and fixed them ahead of time. Its not fair to offer free upgrades, when its essentially a downgrade?
View 6 RepliesToday I installed Windows 10 on my machine (ASUS N55SF laptop) for the first time on a separate hard drive. Now I have Windows 7 on my main hard drive and Windows 10 on my new drive (the latter being an SSD one). After installing Windows 10, I got a new boot option in my BIOS called "Windows Boot Manager" which is set as default, but it runs Windows 10 directly, I can't see any boot manager (I can assure "Windows Boot Manager" behaves this way because my BIOS lets me override the boot option, so that I can directly run any boot option, and this is probably the only way I can run Windows 7 currently).
If I go to Start → Advanced system settings → Startup and Recovery → Settings, I only see Windows 10 in the "Default operating system" drop-down menu, while I only see Windows 7 if I do this while on Windows 7. It's like the two OSs are not completely aware of each other.
after recently downgrading and then upgrading back up to Windows 10 I experienced yet another problem. Now I have no remote access connection manager service. This was discovered by a technician via live support trying to create a VPN connection.
The other problem I have is installing virtual machines. Here are a couple of screen captures with the error messages here:
I don't want to resort to doing a complete clean re-installation of Windows just yet. Furthermore I also did come across [URL] and was wondering if that would bring me back to a normal functioning Windows 7 as even downgrading from Windows 10 in the past seemed to have caused some problems.
When I try to boot from a recovery flash drive, it fails with: EFIMicrosoftBootBCD error status: 0xc000000f and message: The Boot Configuration Data for your PC is missing or contains errors.
The recovery flash drive was created on a Lenovo ideapad originally with Windows 8, now upgraded to Windows 10, latest upgrades applied. Checked the box for copying system files. Target drive was a 16GB DataTraveler flash drive formatted as FAT32. Creation ran to completion with no errors. When booting normally, Windows 10 runs fine with no issues. I tried re-creating the recovery drive with the same results.
I created a repair disk and tried to use bootrec to fix the issue, but I suspect it did nothing or fixed the c: drive. I ran boot rec while in the root directory on the flash drive.
I was playing with disc partitions and i accidentally deleted something... The problem is, that when i start my computer, Windows boot manager error appears (with no options, nothing, just some text about how should i reinstall / repair...), but when i start my computer, i have no way to access BIOS (I know how to access bios in my pc, I was accessing it like 20 times during last few days while installing various OSs... always with F2).
So actually I am stuck in a loop: start pc - cant access bios - windows boot manager error- restart - cant access bios - win boot manager error - restart....
With windows, i had problems with accessing bios before, but it could be solved by some kind of "absolute shutdown" of a system - holding shift while clicking "Shut down" - then i could easily enter bios with F2 during start.
I keep having trouble with my laptop it hasn't been even starting up in weeks, I turn it on and this it's black with a blue window that sus Default Boot Device missing or Boot Failed, insert recovery media or hit any key
Then select boot manager to choose a new boot device or to boot recovery media. So I hit enter and I go to boot manager and boot option menu but there's no options....
I have a Linx 8 tablet running Windows 10, and despite several hours of web/forum trawling I cannot access my BIOS settings to view my boot manager, either through the Settings/Restart method, or in Safe Mode. I can get to a screen that lets me choose between either UEFI Settings or Boot Manager (by holding the power and the volume up buttons together at start up). Selecting the UEFI option takes me to the expected prompt, but choosing Boot Manager just starts Windows as normal. I simply cannot access my Boot Manager; I have disabled Fast Boot.
View 9 RepliesI am getting a strange error after *important* downloading windows from a disc that my work provided me. Since I used the copy from my work, I do not have an installation disc anymore nor do I have a repair disc. To make matters worse, I upgraded to windows 10 but I still get this error. To get past it I have just been pressing f12 and manually selecting my ssd from the boot menu, and it works flawlessly from there. Why can't my computer automatically load from the ssd?
This is the error message.
Boot Manager:
Windows failed to start. A recent hardware of software change might be the cause. To fix the problem:
1.Insert your Windows installation disc and restart the 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.

It's been 2 days since I've first downloaded the media creation tool for downloading Windows 10. Though I haven't received any notifications for reservation, I made sure my laptop's up to the task.
I've the Windows 10 Setup and it doesn't download the OS files (it's always stuck on 0%), and honestly, I am getting so frustrated with exiting the setup, rebooting my laptop into safe mode, deleting folders, rebooting again, restarting download, and repeating the process! Worst of all, when my download hit 68%, it suddenly exits.
IS THERE ANY WAY TO GET THE DOWNLOAD DONE? Or could I get the OS .iso file on any file hosting site do I could know (and monitor) whether or not the download is starting! Because I've spent sleepless nights waiting for the 0% to turn into 1%.

In upgrading from Windows 7 to 10 all seemed to be working but then the desktop manager starting looping flashing as it tries to install the tiles . Cannot get out of the loop. Have tried restarting but the process repeats - after a number of hours the flashes became less frequent but continue to be about 2 flashes then a pause until it restarts multiple quick flashes . It is reporting windows problems and trying to find a fix I presume but after a week of flashes it continues to be stuck. Can get to the task manager but cannot get into safe mode.
View 1 RepliesI have a 3 month old toshiba laptop it crashed last night and now won't boot up a factory reset has taken 7 hrs and came up with file missing il attach pic now it just stuck on toshiba screen spinning no I won't upload says pic is too big
System32/msasn1.dll was supposedly missing at 92% during factory reset
My original os is win7 then i upgraded to 10... After a while of using it... It opens the Blue screen saying unmountable boot volume.. Also i dont have win7 cd since the os was built in...
Next i rebooted it, it says "preparing automatic repair" i tried to wait.. But after it says that, it goes to a black screen and nothing happens
Then i tried dloading the iso from the site and then burned it to a usb.. Then it says
Press any key to boot from USB
*presses any key*
BOOTMGR is missing
Press ctrl+alt+delete to restart
Is the problem in the usb or it just wont open because of the error?
I only have recovery disks on win7
My laptop is Vaio SVE111A11W
Cant open my laptop due to this so i cant really attach the needed files..
In my desktop I have two hard disks ( disk 0 and disk 1 ) . Disk 1 is a clone of disk 0 created by Macrium Reflect
Disk 0 : ( C: ) windows 10 pro , upgrade from windows 7 , ( E: ) windows 8.1 pro , ( G: ) Storage partition
Disk 1 : clone of disk 0
problem description : I see in msconfig / boot a wrong listing
windows 10 ( C:WINDOWS) : Current OS ; Default OS
windows 8.1 pro ( H:WINDOWS ) instead of ( E:WINDOWS )
Nevertheless the dual booting works fine as well as the shift between the disks via BIOS.
The question is , could I fix the situation using the EasyBCD of Neosmart Technologies to edit the bootloader ?
I see can change drive letter H: to E: and save the change , am I right or wrong ? or any other way ....
My laptop has dual boot - Windows 7 and Windows 10. My Win7 environment is my main working environment with lots of programs installed and important files. I installed the Win10 environment just to play around with 10 during the technical preview. Now, I would like to disable the 10 environment and upgrade the 7 to 10. Am I able to do this, or have I already "used up" my one upgrade on this computer's Windows license?
I notice that in Windows 7 I have not received the icon in the notification area that invites me to upgrade to 10. This makes me think I might have used up my chance to upgrade.
My end goal is to have a single Windows 10 environment. Note that the reason I want to upgrade my 7 environment to 10 is because I don't want to have to re-install all of my programs and files into the current 10 environment.
As I get ready to do a clean install of 10074 I am curious about the need to disable secure boot and fast boot options. If I do disable secure boot do I need to enable legacy boot?I have had limited success with previous installs to a 2nd hard drive and the problems that arose always seem related to dual booting.
In one instance I did a clean install of 10061 and had left secure boot enabled. In order to get dual boot working I had to disable secure boot, and upon rebooting I needed to change it back to secure. I then made Win 8.1 the default boot and then Win 10 would never boot from the menu, it would just take me back to the boot menu and I could boot into Win 8.1.
I'm making a image for installation of windows 10. I make a USB flash drive with WINPE. and once the device starts into WINPE, it will automatically start to install windows 10 by calling "dism /apply-image". Normally i just shutdown the computer after installation, but now i want to reboot the device and boot into the windows i just installed. But i can't, because if i reboot the device, it will boot into WINPE again and start another turn of installation of windows. How could i temporary boot into my windows 10?
View 4 RepliesAfter several weeks of testing I'm ready to go full on Windows 10 and want to get rid of Windows 7 but I have some partitioning issues I want to clean up. I currently have Windows 7 on drive 0 (360 GB) and Windows 10 on drive 1 (500 GB). Both are SATA drives and RAID is enabled in the bios but not active.
What I think I'd like to do is simply swap the drives physically so that Drive 0 has my current Windows 10 install on it and make it primary boot active etc. The drive with Windows 7 on it would become drive 1 and I would delete the Windows 7 partition and re-partition it with a clean empty partition just for extra space.
Second question, any advantage to using this drive configuration in a RAID setup?
I have a legacy 64 bit dual core desktop (ASUS mobo). I have several Sata hard drives in it with the 4th partition of my 1 Terabyte drive containing my Windows 10 Professional boot OS. After converting another similar legacy machine to a NAS device I took the old Windows 10 32 bit OS drive from it and tried booting the ASUS machine with it. Needless to say, the OS didn't like it and reverted to Windows 10 Pro Insider Preview edition (build 11082).
When I tried to restore the boot drive to the original one for this machine the master boot was missing.
I had just formatted another partition on the same drive that had contained a Windows7 installation that had failed. This partition may have contained the master boot record. So I booted to a command prompt from a USB drive and successfully ran the following commands:
bootrec /RebuildBcdbootrec /fixMbr bootrec /fixboot bootsect /nt60 SYSbootsect /nt60 all
After that the BIOS just says "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system" This disk and OS are on the original machine it used to run on. As I understand it, Windows 10 tries to record it's key to somewhere in the BIOS. But the BIOS on these old machines don't provide such a facility. I don't understand what Windows 10 OS does with the key in this instance. If it was recorded in the BIOS then I'd presume that the other Windows 10 drive I attempted to use would have found it and used it. Or perhaps not, since it didn't like the new environment.
what I'm looking for is a way to get my original Windows 10 to boot again on the same machine it had always work on before, from the 4th partition of the 1 terabyte drive I'm using.
My laptop suddenly crashed and now it says "Boot media missing" when I restarted. After that, it always takes me to "Preparing Automatic Repair" and then the 'Troubleshoot' menu.
In the 'Troubleshoot' menu, it has two options: 'Reset this PC' and 'Advanced options'.
When I choose "Reset this PC", it asks me whether to keep my files or remove everything. I've tried both and it displays an error. When I choose to keep my files, it says that drive is locked and tells me to unlock the drive and try again. When I choose to remove everything, it says that there is a problem resetting the PC.
And then I've moved to "Advanced options". The options are: System Restore, System Image Recovery, Startup Repair, Command Prompt, UEFI Firmware Settings, and Go back to previous build. I've tried all of these and it all returned an error. When I chose UEFI Settings, it restarted to BIOS/UEFI setting. And my BIOS/UEFI can't detect my hard drive. DISKPART from Command Prompt can't detect it either.
My project is due in 3 days and I've got all my files in there. Is there a way to fix this? Or to recover my files?

I wasn't sure which forum to put this into. I created a backup image on a usb hard drive. I wanted to be able to restore it using a usb recovery thumb drive. I used the create usb recovery tool and created the recovery flash drive. When I try to boot from the flash drive I get an error saying that the boot configuration data is missing or contains errors. I can boot up the laptop using the current windows install so it isn't referring to the hard drive. I have tried several usb drives and get the same message on each. Here is a screenshot of the message.
View 9 Replieslast few hours I spent trying to manually deploy Windows 10 on clean GPT disk but after applying image and rebooting I always end in unbootable state.

After reboot I always end unbootable (as we talk Apple computer it means 1) no partition on Option or 2) folder with ? or 3) just gray screen, make your pick). There's a chance that Windows rely on some UEFI 2.0 feature, which is not available as the old guy has 1.2 only. Or maybe I missed some step somewhere.
