Hello Forum!

I've not fresh event with Windos 7 Ultimate edition SP1 after changing the hardware setup. Basicly I just drop off the old SSD drive from old computer and insert it into new one.
After booting the system, I've got BSOD with information about:

STOP 0x0000007B (0xFFFFF880009A97E8, 0xFFFFFFFFC0000034, 0x0000000000000000, 0x0000000000000000)

Booting crash over \windows\system32\drivers\c4flash.sys

What I have tried to resolve the problem since:

1. Change the boot from Legacy to UEFI - change the partition map from MBR to GUID. Create the EFI partition with link to bootmgr.efi
2. Try to run all commands (Legacy and UEFI) to fix partition (including disk repair) and recovery the boot configuration.

What I think is important, that SSD is Clone from original (I dont want to mess the original Disk and so far I have right cuz I formted backup disk few times since then).
New laptp is Panasonic Toughbook from series C-31 and there is some kind of Panasonic's version of Disk cnnection as I have see - SATA is adapting to the Panasonic hardware, to have easy hot swap option as I asume.

Could please someone can help me with this case? I try to fight with this issue for a week right now and just stoped in the corner without clue...

Please list hardware specs of old and new systems.

0x0000007B error is related to wrong sata controller mode settings.
Possible values - IDE, RAID, AHCI
You have to restore sata controller settings to values on previous system.
BTW - on newer hardware IDE mode most likely will not be available.

No, no, no.
You can't do any of that.

Redo cloning.
UEFI/CSM settings on new system have to be the same as on old system.
MBR/GPT partitioning style has to be the same. You can't change that either.

I hope, you're not trying to clone from sata drive to nvme drive.
For that to work, system needs nvme drivers installed and several windows hotfixes (that add support for NVME).

So I clone the original disk by Disk Genius and looks like all partitions and format become 1:1.

I read somewhere that might be an problem with missing Boot partition after cloning and so far there was a patch to mess with partitions to EFI boot and so on...

Only tip I have right now is that BSOD over c4flash.sys file...
 
Old Computer:
Intel Merom 1.06 GHz dual-core processor
Windows 7 operating system
2 GB RAM
250 GB hard drive capacity REPLACED to 256GB SSD

New Computer:
Intel-Core i5 @ 2.7GHz
The same Windows 7 OS
12GB RAM
Clone of the same SSD

Possible values - IDE, RAID, AHCI
At BIOS I have only two option to choose: AHCI or Capability

Old Computer has BIOS Legacy with 100mb EFI partition.

How can I restore that settings? I have no option over BIOS to change much, and mostly version of configuration to boot I have checked and or I have boot with error with that .sys file OR I have powned boot screen at Windows Hello image and it is no going...

Moving an OS, or clone, between systems often fails.
The older the OS (Win 7) the more likely it is to completely fail.

Just do a fresh install in whatever system the drive will live in.
 
Nooooo... that will be such easy 😀
Sirius - I have application here on disk that I cannot download again (because DEV is no longer available on the purchase-arket) and no one know how to configure it again 🙁

That's why I cloned SSD first and playing that configuration over clone (not the source one). Source one still working and that the story and thats the problem I have 🙁
 
I read about:
bcdedit /set { current } safeboot minimal
but more scary after @SkyNetRising mentioned - have been read about war between instaled OS in IDE vs RAID configuration at Bios 🙁 That might be that game over for this mainboard and little bit of chance to run it force as @USAFRet said?

What application, specifically?

Assuming the original system still works and boots up, your only hope is Sysprep.
https://learn.microsoft.com/en-us/w...alize--a-windows-installation?view=windows-11
 
That's a good TIP !
Can I run the \system32\sysprep\sysprep.exe from secure-boot from rescue Windows 7 CD?

Second think - I was searching few days ago an commerce application to resolve or configure the image befor it will be install over the new hardware - AOMEI Partition Assistand - do You know any other appllication similar to those that ight help do automaticly diagnose and repair disk image?

Follow whatever instructions Sysprep has.
It still might not work.

For your AOMEI - there is no magical "fix it".
Moving a drive with OS between systems, especially laptops, is prone to fail.
 
@SkyNetRising here are screenshots:

Do You need some more information?
 
This is screen from Windows Disk Manager:
Disk 1 is a SOUCE, Disk 2 is a CLONE

This is screen from Disk Genius V5 where Source and Target disk are presented after completed cloning:

Please do not crop screenshots.
You have cut out important information about used space in partitions.
Somehow old and new OS partition sizes do not match. At least used space has to match, if clone was done properly.

Try booting from new drive in old system.
Old drive has to be physically removed for this or clone drive gets messed up (this is important, do not skip).

Boot has to be successful.
If it isn't, then you'll have to boot from windows installation media and perform
Automatic startup repair.

After a successful boot you can move cloned drive to new system.
On new system:
Boot mode has to be set to legacy/CSM (it's not even worth trying UEFI. It will not work, because windows was not installed in UEFI mode);​
SATA controller mode - you'll have to experiment with this setting and find appropriate value. Recommended value is AHCI.​
Then try to boot into safe mode. Press F8 repeatedly after pressing power button to access safe mode option.

After a successful boot in safe mode you can try booting in normal mode.
