yr win10 do not have it own migration software?

which mean yr system do not have OS. But to my understand ; i quote,  "a m.2 sata ssd for this windows 10 os migration" ; obviously mean yrs are system with win10 OS on it. No?

which is beg my previous question.

Disk 0 is your HDD and disk 1 is SSD? I think some steps must have done wrong. Your cloned win partition should not be assigned with E drive letter. After cloned it you should immediately shut down, remove your HDD, boot to bios and change setting so that first boot attempt is to m.2

Try redo the cloning again

after cloning, you should take out the hdd, then go to bios and set up the ssd as os drive. make sure sata operations in bios is set to ahci, and make sure the boot order is pointed to the windows boot manager. assuming your laptop comes with w10, it should be running uefi bios.

by now your laptop should be able to boot up normally.

Maybe some settings in bios not changed?

When you tried doing fresh installation on SSD, you use installation files in USB drive?

Very strange issue. I suspect either it is not properly cloned or there's setting in bios that still not pointed to m.2 drive for boot.

You didn't clone it properly.

Use easeus. Freeware.

P/S
Suggestion of doing fresh installation is beyond crazy.
You may not get your OS activation back.

this is a weird case. usually for cloning all i did was what i mentioned, i.e. clone the original os to ssd; shut the laptop down; take out hdd (so that the laptop has only ssd); boot into bios to ensure boot order is pointed to ssd (uefi bios; secureboot on; sata operations is ahci; csm disabled); save the settings and reboot. the laptops will boot normally.

i suspect something is wrong with the clone on your ssd. did you do diskpart > clean to clean up everything on your ssd before each attempt? if not, try do that, i.e. take out the hdd; boot into os installation screen with your usb bootable; press shift+f10 to bring up command prompt and do diskpart > clean; close the prompt and proceed with fresh installation. a fresh installation always works if the installer files are all good. since the hdd is taken out, it will not interfere with bcd related stuff, and everything will be installed on the ssd.

after making sure a fresh installation can be done and laptop can boot successfully with it, shut down the laptop, install the hdd, readjust boot settings, reboot with hdd, do a diskpart > clean on ssd again (be careful and select the right disk to do clean in diskpart), and try cloning again.

which plextor ssd are you using?

diskpart > clean clears not only all partitions, but visible and hidden settings on the disk that we might overlook sometimes (such as disk type).

afaik not really. diskpart > clean clears everything literally, making the disk like new and untouched (sort of) as a secondary disk, you will need to reinitialize it with disk management.

ok you wiped disk every time before your next attempts. it might be too much but that should work too.

can the ssd work normally as a secondary disk? (meaning booting into hdd then try using ssd as a secondary storage for files); or do you have a compatible pc to test the ssd?

sorry but i'm out of ideas. i had to use fresh installation to check if clone had issues. usually with the right bios settings, and fresh installation done properly, everything will work as is. however in your case, even in a single-disk configuration, fresh installation failed with bcd errors. it might really be the ssd already.

TS, try installing the SSD on a PC just to make sure it's working properly..

that means the ssd is fine. (i.e. bios/os detects it properly; it can be used without issues). however, we still got stuck with a fresh installation in a single-disk configuration that caused bcd errors (which i find it weird, because i never encountered fresh w10 installations with bcd errors in different systems, with different ssds before)

as a last attempt, https://www.easeus.com/partition-manager-so...ows-10-8-7.html

more specifically, have you tried bootrec /rebuildbcd?

Make sure you use the cloning software that is designed for cloning SSD. I think the old cloning software will not flag the SSD properly to work.

try these steps (starting from step.5 since you already reached step.4): https://www.lifewire.com/how-to-rebuild-the...windows-2624508

best of luck.

edit: if the bcd error is the same for your clone and fresh installation, then you can use the same fix for your clone.
