cloned an entire drive (HDD SATA to HDD SATA - DID NOT USE NVME TO AVOID ISSUE)
new motherboard cpu etc. (new hardware)
drive has 3 partitions (in order)
#1 = 100MB boot partition
#2 = Primary windows partition
#3 = 450mb partition assume recovery environment.
After clone boot:
1. Windows 10 boot logo starts. (good you think it's working)
2. error blue screen "inaccessible_boot_device"
reboot to Macrium Rescue 7.2.4808 via usb (I think it booting in legacy / uefi mode not sure which or how to check).
1. click "fix boot problems"
2. click windows installation in c:\Windows
3. Set active partition to C: (IS THIS CORRECT? OR SHOULD IT BE SET TO THE 100MB BOOT PARTITION?)
4. Check all the options
5. Fix starts. Tick on most but set partition boot sector fails. Create BCD succeed.
6. Bios now shows a "Windows Boot Manager" device to boot from
6. Reboot normally: black screen flashes few times & new error "Windows boot manager"
"Windows failed to start. "
Configuration file is missing etc.
So Macrium "fix boot problems" broke the system further
What can I try here?
Should I try manually creating the boot record with diskpart?
I tried this yesterday and did not succeed.
Should I try redeploy hardware? I don't see point of that because this is a boot bcd issue now and is related to Macriums modifications.
I can reclone & restart the process entirely but what do I do differently next time to fix the "inaccessible_boot_device"
I've read many threads & discussions here about this yesterday but didn't find any solution that worked for me
Is this related to the old hardware (6 years) bios being in legacy mode maybe?
I have tried setting new hardware motherboard (Asus) to legacy mode also but not sure if this made any difference.
I read here: https://faststorage.eu/how-to-clone-windows-10-from-sata-ssd-to-m-2-ssd-fix-inaccessible-boot-device/
That if there is mismatch in UEFI vs Legacy you get inaccessible boot device.
