Windows 10: Can't repair my installation

Hi, there's a problem there.

I will show you the typical partition structure for two different configurations.




1. BIOS/MBR-based hard drive partitions




2. UEFI/GPT-based hard drive partitions

You should research your MBR/BIOS of the motherboard you bought and find out if you have legacy BOS only, or UEFI as well.

Of the above configurations, as viewed by Disk Management, the System partition (16Mb) is not shown.
You are lacking a recovery partition. That's about 450 -500Mb.

So, however you created your current installation, it seems it wasn't a normal Windows installation.




Here's my UEFI partition set as viewed by Easeus Partition Manager.

 

My copy of win10 was not got from MS directly, but thru the educational institution.Will it be the cause??

 

I think I know who is the guilty: ME! When I made the image (with Macrium) I must have made an incomplete copy, which later was restored on the SSD.

 

Sounds about right.
Now, if you originally had a HDD and you swapped to a SSD, at that point you need to have ensured you had AHCI enabled in your BIOS for best performance. There are tutorials for that procedure.

Macrium has an option for Windows Backup, which backs up by default all partitions associated with the OS.

You could follow this approximate process:
1. Create a disk image of your 'C:' partition
2. Wipe your SSD and make sure AHCI is enabled
3. Reinstall Windows and make sure the partition size for 'C:' is big enough for your existing 'C:'
4. Restore your disk image in place of the new Windows partition.
5. Run startup repair.

 

Now that we know who's the #1 Public Enemy, I'll do that job. I'll contact later.

 

One more question: is it notoriously important have image done for C: and E: (see mydisk management, please), is not? Or not?

 

Creating disk images for every partition or disk in general is a wise strategy. It's your decision as to when you do that.

 

My SSD is at slot #5. Should I change it to #1 before proceeding to AHCI?

 

Sorry, not familiar with desktops...

 

Well, afterfoloowing your ideas, I have win10 reinstaled from zero, because my image suffered some corruption and did not work well. The most important thing to say is that C: still is without those small partition you showed me.Otherwise it works well

Needless to say that I think you're a very experienced guy. I learned a lot. In my land we call a guy that is good, the good. You are in my opinion, the good

 

Thanks. But I am puzzled about your partition layout. Can you try this..

First look at
Boot to Advanced Startup Options in Windows 10 - Windows 10 Installation Upgrade Tutorials
under

EXAMPLE: Advanced Startup Options at boot for Windows 10
that's what you should see when you do the following:

SHIFT + left click on Restart.

What options do you see?

 

After considering the matter further, I realized that the most direct route is also often the best path: a complete reinstallation of Windows 10 using a freshly downloaded copy of Windows. Fortunately, Microsoft made reinstalling Windows 10 easier than with other versions of the operating system. In fact, you need only download the Windows GWX tool and image it onto a USB flash drive.
A scan from SFC revealed that the corruption remained. When these kinds of issues persist through a clean install, it strongly suggests hardware failure. Fortunately, on a whim, I upgraded to Windows 10 Anniversary edition. After running SFC, for the umpteenth time, it completed without detecting errors.

 

It seems to me that it's good now, after two reinstallations (!)

 

That looks about right for a non-UEFI installation. Good.

Now's the time to create a new base disk image (e.g. Macrium Reflect (free) + its boot medium + external disk) which you cna tehn update periodically. With that you can restore your PC even if you have to replace your disk drive.
