Can't boot freedos after Win10 install solution Solved Can't change my windows 10 version solution Solved Black screen with white cursor when i try to enter bios.
Windows 10 had been successfully installed on SSD for many weeks, then installed most recent upgrade. Windows started slowly but worked, sometimes had to reboot and got 0xc000000e error message.
Tried another SSD which worked fine on same system. Went back to bad SSD and got same error message. Steps: Windows 10 instal disk placed in CDROM and boot up Get error message: 0xc000000e go to command prompt type the following: X: Sourcesbootrec /fixmbr -successful X: Sourcesbootrec /fixboot -successful X: Sourcesbcedit /export c: bcdbackup -The store export operation has failed. Funny, earlier that was successful?
X: Sourcesattrib c: boot bcd -h-r-s -File not found X: Sourcesbootrec /rebuildbcd -Total identified Windows installations:1 X: SourcesAdd installation to boot list? 'Y' The requested system device cannot be found. Go to Advanced options and run the command prompt 2. Enter diskpart 3. Sel disk Disk 0 is now the selected disk 4. Sel vol # (My volume 3 said FAT32 Partition 260 MB Healthy system) 6.
Assign letter=b 7.Exit diskpart tool by entering exit and at the command prompt run the following: 8. Cd /d b: EFI Microsoft boot 9. Bootrec /fixboot Delete or rename the BCD file: 10.
Ren BCD BCD.bak Use bcdboot.exe to recreate BCD store: 11. Bcdboot c: Windows /l en-gb /s b: /f ALL The /f ALL paramet updates the BIOS settings including UEFI firmware/NVRAM, /L en-gb is to localise for UK/GB locale. Also go to this place: It says windows 8 but it works with windows 10.
Bit of a long story here, I will try and keep it simple. I recently upgraded the following components on my computer.
Motherboard MSI 870a-g54 - ASRock Z370 Killer SLI/ac RAM: Corsair XMS 4gb + G.Skilll Ripjaw 8gb - 16 gb Corsair Vengeance LPX CPU: AMD Phenom II 965 - Intel i5-8400 I did not take any measures with the operating system before swapping components, other than making sure to link my Windows 10 account with my Microsoft account. After the change, the motherboard booted up, I was able to enter the BIOS without any trouble, but attempting to boot into Windows 10 I encountered a black screen with a 0xc000000f error. All the drives connected (there are three) and the DVD drive are recognized in the BIOS. I have tried only leaving the boot drive connected, but with no change. I have a boot USB with the Windows 10 ISO file loaded onto it.
I am able to load into Window Repair from the USB drive. When I opened the Registry Key system via the Command Line, all three drives were listed and accessible in the file explorer (I didn't end up changing the registry keys at all, but it was a possible fix I had read about). I also discovered that my old drives were all partitioned with MBR, not sure if that is causing problems or not, but my understanding is the enabling CSM compatibility in the BIOS should address that. Here are the things that I have tried: Startup repair - said couldn't repair it. Restoring to previous restore point - Appeared to succeed, butno improvement Rebuild the BCD - this was attempted through the command prompt accessible via the Window Repair screen. During the process, the windows files were detected, but I couldn't change them because it said system could not be found(?).The only effect this had was to add 'BCD Corrupted' to the black screen o' death.
Not sure that was an improvement. During the process, the windows files were detected, but I couldn't change them because it said system could not be found(?). Upgraded BIOS to latest version - no improvement Made sure boot order listed SSD with OS on it first. Made sure the CSM compatibility was enabled in the BIOS boot system. Tried reinstalling the old Motherboard/CPU/RAM combination in order to remove the files I wanted to save, or see if I could change anything to make it more likely to work, but I encountered the exact same error. Which is weird. I could go for a new reinstall of Windows after reformatting the drive, but I'd like to avoid that if I could obviously.
Anyone have anything else I could try. I've been going at it for four days now, with no success. Any help appreciated. Ok tried what you suggested. It did not have the desired result unfortunately. As you can see in the photos, I was unable to bootrec /fixboot resulted in an 'Access denied' and trying to /rebuildbcd resulted in a 'System not found' message.
The command to 'find osdevice' also did not seem to return anything, which is also visible in the photos. Also not sure why the red line appeared, but I'll worry about that later I guess. Still encountering 0xc000000f error on startup. Any other help still appreciated. Photos can be found here. Diskpart displayed the partitions with assigned drive letters.
What troubleshooting steps had already been done? In the post the use of: next to letters sometimes creates:) So the information in this post is displayed twice, once as the typical post and once using the code. Please use a camera or smart phone camera to take pictures of the commands and results and post images into the thread. The chkdsk displayed that it made repairs although the detail of the repairs was not seen in the report.

@axe0 - No, there was no file mentioned, although the error code remained the same. After I used the bootsec.exe /nt60 command the File: boot/bcd line appeared, which can be seen in the photos. @ - I'll try what you have suggested and post the results. As for the assigned drive letters, no I don't know why they already have assigned letters. As far as I can recall, those were in fact the drive letters they were assigned when the computer was working, but I didn't reassign them during the troubleshooting process.
The steps I had already taken are listed in the original post. I had tried to rebuild the BCD previously, but with the same results (i.e. Didn't have access, system not found etc.). When was bootsec.exe /nt60 used? Was that the complete command? What was the result?
What other commands had been used and what were the results? These are abridged commands: bcdedit /export c: bcdbackup attrib c: boot bcd -h -r -s ren c: boot bcd bcd.old bootrec /rebuildbcd Please use a camera or smart phone camera to take pictures and post images into the thread.
There are more commands after these steps. These are unabridged commands: a) type: bootrec /rebuildbcd (This searches for windows installations not included in the BCD and then asks if you would like to add to it) (It will display that it successfully scanned all installations and the identified installations will be 0 or 1) If 0 it displays: Total identified windows installations: 0 The operation completed successfully.
If 1 it displays: Total identified windows installations: 1 1 D: windows Add installation to boot list? Yes/No/All: b) for option total identified installations 0 the BCD store exists and first needs to be removed manually and then rebuilt.
C) type: bcdedit /export c: bcdbackup (This will export the BCD store as a file: bcdbackup (a file extension is not needed) (It should display: The operation completed successfully.) d) type: attrib c: boot bcd -h -r -s (This removes the hidden, read only and system attributes from the file BCD) (The attributes had restricted the actions on the file and now it can be renamed) e) type: ren c: boot bcd bcd.old (now that it is renamed it should be able to be rebuilt) f) type: bootrec /rebuildbcd It should display: Scanning all disks for Windows installations. Please wait, since this may take a while.
Successfully scanned Windows installations. Total identified Windows installations: 1 1 D: Windows Add installation to boot list? Yes/No/All: g) type: Y then enter key It should display: The operationi completed successfully. (The BCD rebuild is complete.) h) reboot Please use a camera or smart phone camera to take pictures and post images into the thread. There are more commands after these steps. If the above results work you are set.
If they fail then perform the next group of steps: This is the registry backup method: For each step you must see sizeable file sizes for this to work. If you see zeros the method will fail. The command: dir will be used each step to make sure you are in the proper location and check the size of the files 10) type: C: 11) dir 12) type: D: 13) dir Choose the C: or the D: drive to proceed. It should be the windows drive and not the USB drive.
14) type: bcdedit find 'osdevice' This should display the location of the partition and in most cases is the location of the affected drive. For this post I will use C: however you should pick the drive letter that you found that has the windows files on your computer. The prior results did not display a result however the active partition is C: The proper drive will display: perflogs, program files, program files (x86), users, windows, etc 15) type or copy and paste: cd windows system32 config It should display: C: windows system32 config 16) type: dir It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc. All of the file sizes should be sizeable.
If it displays zeros then abort. Make a new directory and name it backup or something similar. 17) type: MD backup Copy all of the files into this new directory. 18) type or copy and paste: copy.
backup It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied. Change the directory to regback 19) type: cd regback It should now display: c: windows system32 config regback 20)type: dir It should display: default, sam, security, software, system etc All of these files must be sizeable. If it displays zeros then abort. 21) type or copy and paste: copy. It should now display: DEFAULT Overwrite. (yes/no/all): 22) type: a It should now display: sam, security, software, system and that the files were copied. 23) type: exit 24) click turn off your PC Remove the USB flash drive if you had changed your boot order.
Otherwise you can leave it and power on your computer. Thanks zbook. The bootsec.exe /nt60 was used after I had already tried to rebuild, but before I posted on here. It appeared to work, but didn't have any effect on the error, other than to add a 'File: BOOT/BCD' as I noted above. Other than that command, I have only tried variations on the bcd rebuild that you had me try, with the same results 'access denied', 'system not found' etc.
I also tried what you suggested, and it seemed to work alright (i.e. I was able to copy the files etc), but had the same error. I was able to boot up with a live copy of Linux on a USB and backup the files I wanted, so I am just going to do a clean install of Windows after reformatting the drive. Thanks for all the help though, I really appreciate it.
