Windows 10 Boot Loader

[Arktius]

Hello everybody,

 

I get a blue screen with the following error code:

 

0xc000000e

 

...device is inaccessible.

 

How did it come to this?

 

I've cloned my OS from SSD1 to a new NVME. I could boot the system even with SSD 1 and 2 being unplugged. I've cloned all data from SSD2 to SSD1 and then got the error.

 

Windows repair didn't help me.

Windows 10 is installed on Datenträger 2 - the NVME. Can I somehow use the partition 2? Wiederherstellung means hereby "Recovery". 

 

If any details are missing, just let me know it. I'll add them.

What do you mean with you were able to boot the system with Drive 1 and 2 unplugged?
Is Drive 2 the NVMe? Is it something else?

 

Did you do a sector-to-sector clone?

Hi @Arktius

 

Windows lost me a little on the following part. Partition 4 is "system" with 100MB that is probably the UEFI (ESP) partition. That should be Partition 1. If I'm not mistaken.

 

Edit : "wiederhelstellun" (Recovery partition)? should be last and system should be first.

SSD 1 and 2 weren't connected to the mainboad. Don't get confused by the output from diskpart. Both aren't listed there. I just call them 1 and 2. We could also name them samsung 830 and samsung 850 if you want. 

 

Device 2 is the NVME with Windows 10 installed.

 

I did a sector-to-sector clone. I used easeus backup.

Are you sure? According to this website it says:

 

The System Reserved partition contains two important things:

• The Boot Manager and Boot Configuration Data: When your computer starts, the Windows Boot Manager reads the boot data from the Boot Configuration Data (BCD) Store. Your computer starts the boot loader off of the System Reserved partition, which in turn starts Windows from your system drive. 

...

The System Reserved partition consumes 100 MB of space on Windows 7, 350 MB of space on Windows 8, and 500 MB of space on Windows 10.

Yes I'm quite sure. I'll quote from wikipedia. Looked it up to confirm my story. Mind the " Before the primary partitions". Unless diskpart shows it in the incorrect order then the partitions are not correctly located.

 

Quote

The MSR should be located after the EFI System Partition (ESP) and any OEM service partitions, but it must be located before any primary partitions of bootable Windows operating systems.^[1] Microsoft expects an MSR to be present on every GPT disk, and recommends it to be created as the disk is initially partitioned.^[5

I checked my own drive to be sure and he's correct. The 100MB partition is the EFI-Systempartition.

 

 

The error shoul've never come up in the first place, if it has worked to boot the system before.

 

I'd go through the usual trouble-shooting steps.
Reseating the drive, CMOS reset and such.

But tbh I don't have much hope. The installation is probably bricked and you'll have to reinstall Windows.

But the system had booted before on the other SSD with the same order for the partitions.

 

The order of the partitions shouldn't cause the error.

Quick fix: make a bit by bit clone this should work all the time. Boot linux USB and execute following command. From there its a waiting game. Also make sure you don't mess up sda with sdb or you will clone it the wrong way around. ( if = Is the source / of = is the destination )

dd if=/dev/sda of=/dev/sdb bs=64K conv=noerror,sync status=progress

Edit: if this does not work you Windows installation has some serious issues, this has worked for me 100% of the time.

Yeah I agree.

That's what's so weird about it.

Could explain what it's exactly going to clone? 

 

The command bootrec /scanos found a Windows installation on J. Can't I use the command bootrec /rebuildbcd?

Yes it will clone drive A (sda) to drive B (sdb) to a exact copy so also with empty sectors the destination disk should be larger then the disk you are about to clone though.
