cloned C: drive locked and unbootable Windows 10

I bought the computer with Windows 8.1 Pro. I requested and then upgraded to Windows 10 Pro. I began having 'error 1962: OS not found,,,' intermittently. The drive is a 2tb Seagate drive. There are 6 partitions on the drive from Lenovo and Windows is #4.

I cloned the C: partition into a new Seagate 3tb drive. That left me with 2tb + the leftover unallocated. I combined the two pieces in disk management to make one large partition with only the C: partition from the old drive.

It is not bootable. I get error 1962: OS not found when I try to boot from it. The drive appears to be locked. I used cmd.exe as administrator and ran diskpart and volume commands and the drive is not read-only or otherwise restricted. I have tried Bootsect and Bootrec with /fixmbr; /fixboot; /rebuildBCD commands but no success. I suspect it is because the big drive is GPT instead of MBR.

I have the Win 10 upgrade on DVD and tried refresh but it says the drive is locked. I have done the boot diagnosis but it tries to fix it without telling you what it is doing and in any case it does not fix it.

I think my problems are based in trying to get away from the extra partitions that are no good anymore and also that I am using GPT instead of MBR. I think the old bootmgr is looking for partition 4 and I am unable to change it's mind.

If anyone has an idea I would like to hear it.

if you imaged the bad OS to another disk - it is normal it does not work
you have to repair that first
you can try the boot corrector tool from the paragon rescuee kit :
http://www.paragon-software.com/home/rk-express/      

i would run a diag on the 2 TB drive -  i use ubcd for this, see below :
then it can help running the HDDregenerator, it fixed many drives for me
http://www.dposoft.net/hdd.html      
--------------------------
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

http://www.ultimatebootcd.com/                        ultimate boot cd
http://www.ultimatebootcd.com/download.html             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems : http://www.experts-exchange.com/Storage/Hard_Drives/A_3000-The-bad-hard-disk-problem.html

Hi nobus, Thanks for those great ideas.

I was reading a thread earlier about migrating to an SSD and was pointed to Paragon software.
This tool; http://www.paragon-software.com/technologies/components/migrate-OS-to-SSD/  does exactly what I need.

I know this because earlier this evening I bought it ($20) and ran it and it works perfectly the first time with my GPT disks.

I just re-cloned over my previous one choosing to make the boot records.
It still made a recovery partition and an EFI partition and I do not know why but who cares. They are tiny relative to my 3tb drive.

I am over the moon. Days of work done in 3 hrs with the right software.

Closing this out.
Thanks again for your thoughts on this.

Your problem was that cloning C: partition is not enough. It can boot only if boot files are also on C: but they are normally in MSR or EFI partition (depending on which type of HDD you use - GPT or MBR).
Using Migrate OS to SSD which automatically clones this partition additionally to C: - solved your problem.

All of nobus' comments were great and useful but not necessary for this problem. I gave him most of the points anyway for sharing his knowledge. The Paragon software handled it in one run. EE always comes through.
