Installation :: Deleted Boot Manager Along With Cleaning Old HDD
Dec 20, 2015
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 set up Ubuntu in dual boot with Win 10 and tried to replace it with Mint, which failed at installation. I then had a "grub rescue" prompt regardless of what I tried. I fixed the mbr by booting from Win 7 .iso and running Bootrec /fixmbr.
I can now boot into Win 10 OK. However, when I first installed Win 10 and dual boot Ubuntu, the Windows 10 selection screen used an icon for Win10 and for Ubuntu. Now the Win10 selection screen is all text, like the original Win 7 screen before Win 10 upgrade. Possibly because I used a Win 7 .iso. I can't find how to get to a dos prompt when booting from Win 10 .iso. It is only cosmetic, but how to restore the Win 10 icon type.
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.
Okay, so the other week i received a new Clevo P650SE laptop. The laptop only had a 500GB 7200RPM HDD with Windows 10 to begin with, so yesterday i added my Samsung 840 EVO SSD. As i wanted this to now be the primary drive, i made another new installation of Windows onto here. After doing this, the system now displayed a boot selection at startup with the choice between the new Windows 10 installation on my SSD or the old one on the HDD.
As i no longer wanted to use the HDD for running Windows, i decided it would be best to delete Windows from this drive. So i booted onto an Ubuntu USB and wiped the entire drive of it's data in GParted, which included three different partitions. This seemed perfectly fine to me at the time, because i had a the new installation from the SSD showing up in the boot manager.
However, when i rebooted the machine and attempted to boot into the new installation on the SSD, it gives me this message:
"The boot configuration data from your PC is missing or contains errors. File: /EFI/Microsoft/Boot/BC Error code: 0xc000000f"
I have tried everything to recover the system but nothing has worked. Startup repair from my Windows USB doesn't do anything, the system reset wouldn't operate because it stated that the partition was locked.
Nothing with the Command Prompt is working, I have done 'bootrec /fixmbr', 'bootrec /fixboot' and 'bootrec /rebuildbcd', but the last command returns the following error:
"The requested system drive cannot be found."
I also did 'bcdboot C:/Windows' but that also refused to work. I assumed the reason for this might be because the drive didn't have a letter, but when i attempted to add a letter is says:
"The specified drive letter is not free to be assigned."
Both drives in my laptop have now been completely wiped and converted to MBR, but even with the two drives empty the original message still appears when booting my Windows USB in UEFI.
I have only had this laptop a couple of weeks and it's already completely messed up. I can boot the Windows USB in Legacy and install Windows as normal, but of course i'm looking to have it back on UEFI as it was before.
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....
I used MicroTool partition manager to delete the extra partitions on an OS drive with win10 (leaving just the main C partition on the drive), and now the laptop will not recognize the SSD with the OS on it, and obviously cannot boot. I also tried using the bootable partition recovery tool from MicroTool, but restoring the partitions also does not work, it will only allow one of the two partitions to be restored.
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 was messing around with partitions and created a test partition that was unfortunately the same size as my EFI partition. I went to delete my test partition, but deleted the EFI partition by mistake and now my computer won't start.
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.
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 ...
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 deleted the win7.old folder is there another way to install win7 by removing win10 and still keep the files, since it's saying it will completely delete win10 and files and folders but I want to keep the files I have there
I had the Windows 10 install files in $WINDOWS.~BT and $Windows.~WS totalling >5GB. A few days ago I decided to also download the Windows 10 ISO.
I've now found that the 5GB+ installation files have been deleted.
I'd like to have both options regarding the upgrade and so would like to re-download the installation files. How do I get them re-downloaded?
If I click the Get Windows 10 icon the only option is Upgrade Now, not what I want - unless that will initiate a download and then give me the option of not starting the actual upgrade.
I waited for Windows 10 to get rid of Windows .old and Windows.~BT folders but it never happened. If the scheduled task for disk cleanup is supposed to do it I discovered the task will only run on my laptop when I am plugged into power and only if the system is idle. That does not happen very often on this laptop.
So I decided to use the disk cleanup app built into Windows to remove previous operating systems and installation files. It got rid of the Windows.~BT folder and emptied the Windows.old file of everything except one folder within Windows.old for something in folder AMD64_prnLx00.inf..... and file Lxktptprc.dll.mui. I can not delete or rename it and I have the correct privileges. This laptop has dual boot with Windows 8.1 on one side and Windows 10 now on the other. Windows 10 upgraded my W7Pro side over a month ago.
I got all my space back but would like to know if there is a way to finally remove the Windows.old folder.
Is it safe to use Local Disk (D as my backup storage? i don't have an extra HDD so i want to transfer my files from (C to (D instead but i'm worried Windows might delete them if i do the reinstallation.
Iinstalled windows 10. After installation, my files were ok. Immediately, i moved them to the desktop and documents. Then, i restart the pc. Then i see that all my files (on desktop and documents) are gone. My programms and other files are ok but the ones that i moved to desktop and documents were deleted. How can I restore them?
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.
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?
