I am having trouble with my windows installation after attempting to install windows 10 a second time on the same machine, but different partition.
I have used a bootable USB device with the windows 10 installation (created with the same machine and the same settings for OS).
After pressing F12 and selecting the USB as the boot device, i started the installation process and got to the stage where you select which drive / partition to install windows. But the list only contained the USB device i used to start the installation process, and the SSD did not appear when tried to refresh / reload drives (or unchecked the "hide incompatible drives" checkbox).
After canceling the installation process, i was met with the following message when rebooting windows:
"Your PC/Device needs to be repaired.
The Boot Configuration Data file is missing some required information.
Error code: 0x0000034
You'll need to use recovery tools. If you dont have..."
Before the error occured:
I have tried many different things BEFORE i got to the step above where I was able to start the USB stick and consequently ended up with the error.
However when the error occured the BIOS was reset to factory settings and i was able to log in to windows (and listen to spotify for an hour or so) before i tried the install that gave the error:
After the error occured:
I can not see the "Windows Boot Manager" in the list of bootable devices anymore. Im guessing this is the main issue.
I tried startup repair, system restore and system recovery image from the troubheshoot dialog on the USB stick, but i dont have an image and the restore / startup repair fails.
The main SSD drive is still detected in the boot sequence (now on top). And it is also detected in the boot sequence UEFI interface.
I did a Dell diagnostic scan of the system and it did not give me any errors with the hardware. Everything seems to work just fine (only got a warning that the power cable was not plugged in).
I followed a guide after googling the red error text above and tried the following commands in the command prompt:
but no windows intallations are detected after running those commands.
Total identified Windows installations: 0
So then i figured i would follow this guide: www.lifewire.com/how-to-rebuild-the-bcd-in-windows-2624508
to rebuild the bcd. But when i tried the first command:
bcdedit /export C:\bcdbackup
I get an error saying:
The store export operation has failed.
The requested system device cannot be found.
And if i scan for disks (i thought the C letter might be wrong), i get two disks: C and X
bcdedit /export X:\bcdbackup
(with X instead of C) gives me the same error.
This is as far as I have gotten. Maby i simply dont have a bcd device to back up? (i dont really know what that means).
I dont expect to get my data back, all im hoping for is a clean install again.
Thanks for any and all replies.
Solved! Go to Solution.
I downloaded and ran the dell recovery media from a usb stick and reformatted / reinstalled windows 10 on the machine. So the ssue is resolved
I experienced a weird bug in the process tho, when installing the recovery tool on the usb drive.
The tool is called "Direct Key creator" and when i startet it up, all texts and headlines in the program was just placeholder texts:
And since the drives were all named IDS_DISK_DESC i had to unplug all my other external drives in order to be sure i installed the software on the correct one.
And another thing,
When i booted the recovery tool i got to a step where i was told that the disk was locked and i had to provide one of three options to unlock it:
I figured this is because of the bitlocker encryption on the drive and that I had to provide the bitlocker key to unlock it.
The dropdown was empty, so no luck there. The numeric code i figured was the bitlocker key, so i provided that key, with and without the dash in between each segment of numbers, but no luck. I also tried inputting my user password for the administator account i usually use to unlock the drive when i log on. But that did not work either. I kept getting a prompt saying something along the lines of "drive is still locked, abort?
Instead of aborting I skipped the step and continued with the process. The recovery tool allowed me to completely wipe the drives with the encryption, and i didnt have anything of value so that was ok.
I know that it might have been possible to decrypt the drives through the windows troubleshooting command promt, but thats not an issue now.
