Windows 10: How to Combine C: Drive Partition with MBR with D: Drive OP SYS

Hello,

I have gotten into quite the pickle. I had to restore my disk with Acronis. However, I had picked the wrong disk and the MBR got misplaced. Now the SFC /scannow does not work and after any windows update, my computer becomes non-bootable.

I noticed that my operating system (Windows 10 Pro) is on a separate partition marked D: and my C: drive is on a small partition marked active; which I'm assuming contains the MBR. These two partitions are on the same disk.

I am thinking that when windows update happens, it cannot find the Operation System and all goes haywire. I end up having to reinstall from Acronis rescue disk, as repair does not work.

Is there a way to combine the two partitions on the disk?

I should also mention that all my file folders are on a separate disk titled :I <--- not sure if this matters, as all my Windows install is on the disk I mentioned above. I did find something troubling. From my Acronis rescue image it appears that a MBR has also been assigned to that disk. However, there is no operating system there.

Thank you in advance for your time and help.

:)

Please help.

 

Windows Store Error 0x80070490

Every time i try to install anything from the Store to my "D:" Drive it just quits with the error "0x80070490". Installing on my "C:" and "E:" Drives is working. But since those are both only 500GB in size and only about 250GB free on C and 100GB on E it
doesn't make sense to me to install it onto there. On my D Drive i have plenty of space (about 1.3TB Free)

Here is what i did before the error happend:

I had another HDD as an D drive it was an 1TB drive with MBR. My new D Drive is an 3TB Drive with GUID (since MBR can only create partitions up to 2TB).

I did clone my old D drive to the new drive with clonezilla and partition to image and image to partition otherwise it wouldn't work cause i would need both HDDs to be MBR.

Since i done this i can't install apps from the windows store. On the other two everything is working fine but on this one this error happens.

 

Normally there is a small partition system reserved about 100 meg which is active and contains the boot files so if needed it can load bitlocker tool to read an encrypted c drive. Then you have c drive which has all the windows files on it you need both partitions setup correct for it to boot this is assuming you are using a MBR disk and not a uefi drive which will have other partitions as well. The small boot partition shouldnt normally have a drive letter you cant simply join the drives as the boot will look for a second partition to load windows

 

Drive letters as seen in Windows repair or other repair facility are assigned for it's use and have no relationship to those seen by Windows.

 

I am lost as to what to do at this point. The system will not run sfc scan now. It will just say it cannot complete this operation. I have done chkdsk C: /f /r /x and it shows all kinds of corruptions and then says Failed to lo transfer logged messages to event log. "Status 50"

I also get this error after windows update and failed reboot. System failed to extract the file H:\windows\syswow64\migration\bthmigplugin.dll

I have been at this for weeks! I really cannot afford a clean install of Windows. Does it look helpless guys? Any suggestions would be appreciated.

Just run the update tool and that writes a new o/s with no data loss which may solve it Windows 10

You say I have been at this for weeks! I really cannot afford a clean install of Windows there is no cost for win10 you can do a clean install for free

 

What I have been doing is reinstalling my last good config from Acronis, doing my daily work, and then trying a few fixes I find online. Unfortunately, once I shut down my computer, I wake up to Blue Screen of Death. Repeat! It's a horrible existence.

I use my computer for work and have tons of programs installed. To have to reinstall everything will be a huge undertaking, thus trying to find the solution to avoid that. *Sad

I should have mentioned. Windows 10 was reinstalled by Windows Remote Assistant tech. This is the image from right after that install that I'm using. So I don't think that will solve my problem, unless, I do a complete wipe.

Thank you so much for taking your time to reply. It means a lot to me.

 

I ran the update tool as suggested. Figured it couldn't hurt. I noticed it reordered my Disk assignment. C: is now assigned Disk 2 and my blank F: disk I use for film renders is in the Disk 0 position. Does this matter? Picture attached.



Just for my own knowledge... Why did it do this?

I don't know if the crash at reboot is solved yet. I will report back.

Thanks again for your time! I know it's valuable and I really do appreciate it!

 

Thank you Samuria
I'm at a loss as to why the Windows reinstall worked with the link you provided and did not with when Windows live support did the reinstall. Your version gave me a newer version of Windows with a cleaner layout too. The SFC /scannow works and reports no violations. My computer started with out a blue screen today!

I did have to reinstall my Kaspersky and video card drivers and both gave an error that said "memory could not be located" With a error code at restart after the uninstall. However, the reinstall went fine and everything is working at this point.

Thank you again. Still not sure why my disks got reordered? I know you're busy, but if you know why, would love to know. Just curious.

Thanks again!
