Boot Manager Error - A Recent Hardware Of Software Change Might Be The Cause
Oct 17, 2015
I 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.
Status: 0xc000000f
Info: The boot selection failed because a required device is inaccessible ...
Today 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.
I have a Windows 10 Home machine that recently went through a windows update and restarted. It now boots past the BIOS and goes through "Windows Updating" to "Windows Diagnosing/Repairing" boot loop. My computer uses an SSD so it is (I believe) impossible to get it to boot into safe mode. Is there a way to boot into safe mode or rollback the update somehow?
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 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.
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....
or a few days now I am unable to install or uninstall anything, do a anti-virus-scan, run anything as administrator, opening an .exe-file or simply opening the Task-Manager. I always get the same error message (see attachment). Except when I'm in Safe Mode.
Avira-Systemcheck in Safe Mode doesn't find anything bad and so I have no clue what causes this and how to repair it.
I recently upgraded to windows 10 and now my verizon wireless "VZ access manager" doesnt work right. It still connects, but When I go to the statistics page the tx rate and rx rate is 0. My laptop which is still windows 7 still works fine.
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 ?
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.
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....
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.
I installed windows 7 as a dual boot with windows 10 (as I was having some compatibility problems with some programs) but now the boot UI has gone back to the old black text based UI.
I was just wondering is there a way to get the modern blue boot UI back?
I am trying to have my computer boot Linux by default, from an external hard drive, while my internal drive has Windows 10 on it. Unfortunately I cannot get it to work: Windows 10 boots automatically at every restart and cold start.
Steps I've taken so far:
The boot order I want is set and saved in BIOS. There's no uEFI on my computer.
Windows 10 fast startup option is disabled. I also disabled the hibernation option just in case.
Still, I can only get Linux to boot by going into BIOS every time and selecting the (already selected) external hard drive again. When I then try to mount the internal (Win 10) disk from within Linux, I get an error saying it cannot be mounted because Windows 10 is still using it.
how to solve this and give full boot control back to BIOS?
Have a Lenovo H420 desktop that was upgraded about 2 months ago. We backed up everything and want to reinstall Windows 7.
But I can find no way to get into the Setup screen. I've gone to Settings, Update & Security, Advanced Startup and Restart Now. But I have no option to Use a Device. If I choose Troubleshoot then Advanced Options, the subsequent screen has no option for UEFI Firmware Settings.
I've disabled Fast Boot through Power Options in the Control Panel, then tried F2 and the Delete key when starting. Nothing...
The fact that I can't do something that was so easy in Windows 7 is enough reason in itself to remove 10. Throw in the fact that the scanner part of my printer no longer works is just icing on the cake. I have the Windows 7 disk. I just can't figure out how to use it.
I just bought an ssd. i installed it then windows didn't detect it so i format it and everything now its working. So I decided to go into the bios to make my win10 boot off of the ssd then the hard drive as a secondary then i save and exit and turn my pc off to test the boot. i get a message saying change the boot device and when i kept restarting it it kept popping up. so i had to unplug the sata data on my ssd. not since its connected, win10 will boot off of the hdd. then i notice after i unplug it and turn it on it wont even give me an opportunity to enter the bios windows automatically starts up; there is no logo of my mobo brand with controls on how to enter the bios under it. i still press the button that would let me enter but nothing happens but win10 starts up. so after that i plug in the ssd and now its not detected and it wont let me format it as if its not even installed in my system! NOW I CANT ENTER THE BIOS AND A USELESS BRAND NEW 250GB SSD...
When I boot up my Windows 10 PC, I keep getting this error 0x0000020 and there are about 10 Error boxes. All starting with DX10, DX11, or DX12 in the title. [URL] .....
The entire box says: DX11: igoproxy.exe - Bad Image
C:WINDOWSSYSTEM32 vmgf2um.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc0000020.
I recently upgraded a Toshiba A300 laptop (2009 model) from Win7 to Win10. I use a 125GB Kingston SSD as primary and a 280GB Hitachi as a secondary internal hard disk, in place of DVD drive, inside a cradle. This is a single OS installation, no dual boot. When I cold boot (from power on) and after the Bios logo, the "MBR Error 1" appears on screen and stops booting. To bypass I do a warm restart (Ctrl+Alt+Del) and the second (warm) boot loads Win 10. Also booting is ok from a Restart. Again error message appears only after a cold boot.
As a teaser I have to mention that, whenever I remove the cradle with the secondary Hitachi hard disk, the error does not appear during cold boot !!!. That is the error message appears only if the second hard disk is installed. This is an annoying situation only and does not affect any other operation, except booting.
Yesterday I removed dual booting Linux and after that my Windows 10 won't boot up. I have tried everything. The cmd commands: bootrec /FixMbr; bootrec /FixBoot; bootrec /RebuildBcd; Bcdboot commands and everything. Then I tried Refreshing PC what says: Drive where Windows is installed is locked. Please unlock it.....
Startup repair just scans for a short period and then says: Couldn't fix the problem. I can't Access normal Recovery options, so I'm using a recovery flash drive. I have tried several Live CDs but none of them won't fix the problem. I can access the UEFI Bios, but idk what to change there. I don't want to fresh install Windows, unless it's the only option, because it contains important data.
Windows 10 goes through the entire download/installation process, restarts, blue screens with a "system thread exception not handled (iastora.sys). It then restarts and shows this error for windows 10. Am I screwed? It goes back to the desktop and works somewhat (other than windows 8.1 bugs). I don't have any files on this computer that I need to keep. I just want it fixed!
I installed Windows 10 earlier but after about 10 minutes of using it my computer restarted itself automatically, and then it showed an error message saying that windows had "ran into a problem" on restart an it quotes the error code "0xc000007b".
I have taken a photo of it which can be seen here: [URL] ....
It then restarts again and gives me a list of options: [URL] ....
