Windows 10: Windows 10 doesn't boot anymore after flagging partion as active

Hey guys,

I'm having problems here. Here's my situation: i have 60GB SSD and two SATA disks with Windows 10 on the SSD disk. But because the small 60GB SSD was always running full, i've bought a 250GB SSD yesterday. So, i disconnected one of the SATA disks to connect the new SSD disk, but then Windows 10 wouldn't boot anymore, so i figured Windows 10 has a system reserve partition on the SATA disk.

So i looked it up how to move the system reserve partition to C: (SSD) and did the following cmd command: bcdboot c:\windows /s C:

After this i had to flag the C: partition as active in Disk Managment. But, here comes the problem, i did it the other way around. And after that i set all 3 partitions as active and now i get the following error when Windows 10 tries to boot:

"Your PC needs to be repaired

File: \Boot\BCD
Error code: 0xc0000034"





What i have tries so far:

-bootrec /fixmbr
-bootrec /fixboot: getting the error "Element not found"
-bootrec /rebuildbcd
-bcdboot c:\windows /l en-us, getting the error "Failure when attempting to copy boot files"
-bcdedit shows ""The boot configuration data store could not be opened. The requested system device cannot be found."

Then i installed a clean Windows 10 on the new SSD. Offcourse this worked. After this i used Minitool Partition Wizard to clone the old SSD to the new one. And then it start all over again (which is maybe obvious). So now i have my hands in my hair, actually. Who can help me out? Thanks so much in advance!

Windows update 2018-01 Windows 10 version 1709 (KB4056892).

After update Windows update 2018-01 Windows 10 version 1709 (KB4056892), windows doesn't startup on my HP Compacdc5750 Microtower.

The only way for me to solve this is to restore my C partion.

Please tell what is wrong.

Win10 doesn't power off when Shut Down is chosen: intended behaviour?

Solved this: Win10 won't complete shutting down if the partition it is installed on is not marked Bootable/Active in an MBR partition table (possibly GPT also, but I don't have the means to test). Most likely it's trying to find the Boot partition so it
can note the creation of a hibernation image for fast boot.

I expect this scenario doesn't normally arise because the Microsoft boot sector would require a Bootable flag and the installer will set it. I ended up in this situation because I had to generate the BCD myself (using bcdboot) after Windows Setup installed
it on the wrong disk, and am using GRUB as my master boot loader, which doesn't care about the Bootable/Active flag.

Other symptoms included bcdedit and msconfig not knowing where to look for the partition containing BCD (although Disk Management apparently did guess correctly). BCDEdit would report that it couldn't find the requested device unless explicitly given a /store
flag to show it where to look, and MSConfig would show a blank Boot tab.

 

Welcome to the forum. Not clear you clean install to new ssd but then you cloned the old one to the new install is that correct? Are the drives mbr or gpt ? You should always do a clean install with only one drive connected so you know we're boot files are going

 

Hi, thanks.

Yes, did a clean install to the new SSD after i couldn't boot from old SSD anymore. I did a clean install with only the new SSD connected. They are MBT. After that i was hoping that i could clone my old SSD to the new SSD and that it worked. But unfortunately, it doesn't.

All i want to know now is, what i can do so that Windows boots again. Thanks so much for helping me out.

 

I solved it! This was my solution:
