Windows 10: Deleted recovery and boot partitions; can no longer boot

I used MicroTool partition manager to delete the extra partitions on an OS drive with win10 (leaving just the main C partition on the drive), and now the laptop will not recognize the SSD with the OS on it, and obviously cannot boot. I also tried using the bootable partition recovery tool from MicroTool, but restoring the partitions also does not work, it will only allow one of the two partitions to be restored.
Any suggestions to recreate these necessary partitions?

Scan and repair drive at each start up since update 1703 was installed

Hi,

You will not believe this... After spending several hours getting my machine working properly again, and after doing a clean install of the Creator's Update 15063 (1703), I can no longer duplicate the boot problem...

Every attempt I have made to delete the Windows partition has been recovered with little problem...

If I delete the partition with Partition Wizard and reboot, Windows does a Automatic Startup Repair all on it's own and recovers the deleted partition !!!

If I restart and boot back into Partition Wizard after deleting the partition, use the Recovery Wizard, the machine again did a Automatic Startup Repair on it's own... without any media... and booted...

I am now suspecting that the upgrade process may have changed something that is causing this not to work... Both your machine and the one I was able to duplicate your problem with were some type of upgrade...

Maybe the upgrade altered the functioning of the Automatic Repair, or possibly that it was deleted when you deleted the 971MB partition I thought was causing the repair error...

I has also deleted a no longer wanted Recovery partition...

I have just upgraded the 15063 (1703) to 16299.19 (1709) Fall Creator's Update... I will try this again and see what happens... The only problem is that the upgrade did not create a second Recovery partition like you had, or my machine had previously...

I wanted to let you know how things stand before I proceed, as it may be awhile before I can post again.

 

what is the new hard disk drive that appeared on my windows 10 pc

Win10 can have up to four partitions on the boot drive.

One is a recovery partition, another can be a uefi partition, then the os.

If this other partition is on the boot drive it was created by windows on install.

Do not delete this partition because if you do and you need to reset the pc you will not be able to, it may not even boot at all.

I am not sure if recovery partition is from the first install or gets updated on new builds.

This is not the same as system restore points made in windows.

 

Install Macrium Reflect Free on an operating computer. Create a rescue USB/DVD with it. Boot the laptop with the Macrium rescue USB/DVD. Under the restore menu is an option to fix windows startup problems.
Macrium Reflect Free


Also, Kyhi's Bootable Windows PE might have EasyBCD on it. You can use EasyBCD to create boot files from scratch:

If you have an UEFI bios you are probably going to need to create a small (150mb) FAT32 partition to hold the boot files. But you can try just putting the boot files on C: drive first.

 

I tried Reflect, the repair takes almost no time and it didn't work... so ya.
I am in the process of using a bootable EaseUS Partition manager and using their online instructions for this problem to fix it. I will post how it turns out.
I am also not sure if my bios is UEFI.

 

If EaseUS Partition manager does not work.
With only drive C: connected. Boot up with Macrium Rescue disk again. Click on the Command Prompt icon on bottom left then type:

• Diskpart
• select disk 0
• list par
• exit

Copy and paste the result so we have an idea if your Windows was installed using GPT or MBR disk type.
Then we can suggest what need to be done.

 

Still trying to get EASEUS running

 

No luck with EASEUS or even Aomei partition manager
By the way, I am running Kyhi's bootable OS in attempt to get somewhere

 

You can use MiniTool to copy, delete or move partitions, you have to remember never to delete the "reserved" or the partition(s) that seem to be "unallocated". You mau be able to recover those partitions if you use a tool like Hiren's Boot CD that has Partition Wizard 7 included, if not, MiniTool sells a partition Recovery tool that may or may not work, I think in your case though, by deleting those partitions you have lost your Boot partition.

See below, this is my Windows 10 partition. There is an Unallocated, then a reserved, then at the end there is another unallocated. These are all created with Windows Setup during an initial install. Maybe there is some way to re-create those partitions on a new drive, you would have to copy the partitions marked 1 and 2 from a valid Windows 10 HDD first, then you could copy over your main System partition. Then copy that final partition and make sure it ends up at the very end of the drive. I've done things like this before when Moving my system drive and it worked, but the partitions I copied were all the original partitions from the system drive. You could try this, but it would have to be copied from a system that had the exact same version of Windows 10 as you had there. But it is a longshot.

I've done what you did before and lost my whole system, I don't know if there are other ways to recover it. For future reference, note the image below and if you ever do this kind of thing in the future, leave the 3 selected partitions alone. Also give Navy's suggestion a try.

 

I could indeed try copying partitions over from a fresh install on another system. I have other laptops and other hard drives to use.
I just don't know how to copy partitions or copy them in the proper way to get them to work together.

 

I would try to fix the bootmgr

Jagwar, just have both drives (plus a new empty drive) installed onto a PC. It's best to use Hiren's Boot CD to boot outside of your OS, Use Windows XP lite which is on the disk to mount an XP. Then open Partition Wizard, its in the Partition area of the Hiren's menu. In ytour case you would have to have 3 drives mounted, your hosed original, the working Win 10, and an empty drive. If you don't have enough SATA ports, then put one of the drives into an external USB case.

Start by copying the first two partitions from the WORKING Win 10 drive. Hit Apply and it will copy. Then, copy the main partition from your hosed drive. make sure you leave room at the end for the final partition, and after the main data is copied, then copy the partition at the end of the Good Win 10 disk to the new disk.

It's because Partition Wizard copies partitions in the exact order of how you choose them for copying - Actually, it's best to copy each partition one at a time so that they get copied in the right order. It only takes a few seconds to copy the boot and reserved partitions, it will take up to an hour to copy your main system partition.

 

FYI, I built my own Recovery disk similar to KYHI's and it contains a set of tools such as Macrium Rescue, Mini Tool etc... The same as if you use Macrium Rescue disk and in your case, it won't do any good if you don't have those partitions that were deleted.

Your SSD is a GPT disk. However, the result from list par looks very strange. The System partition is 200 GB and the primary partition is only 3086 KB. Normally the System Partition for a GPT disk is only 100MB and the primary partition is where your C drive is.

@whs
Please note his disk is GPT Type and you are refering him to the links for Windows 7 using MBR type disk. They are completely different, you cannot use bootrec/fixMBR on a GPT disk, there's no MBR to fix.

@XweAponX

His disk is GPT while yours is MBR and Hiren's CD does not recognize GPT disk.

 

Thanks for alerting me to the GPT detail. I missed that. I think I am getting too old for this stuff.

 

Use KYHI's disk to boot and run Mini Tool Partition, right click->Explore on the 200GB System partition to find out if it is indeed the C: drive. You can tell by looking at the folders such as Windows, Programs Files etc... Apparently you did more than just deleting those partitions. If you still have the C: partition then we can proceed to fix it. If not, you are out of luck.
