Ubuntu and several Windows partition is not detected in Windows Disk Management | Dual Booting

I have a problem regarding dual-boot installation of Ubuntu. I'm not very familiar on dual-booting but I follow several turtorial to do it. During installation of Ubuntu as dual-boot, I did not choose the option of manually partition, instead i choose the automatically partition and resize it to match the amount of unallocated storage. After installation, it works perfectly fine for both windows and ubuntu. However I found that my Ubuntu and several partition is not detected in Disk Management.

The steps for installation:

• Shrink local disk E: (HDD) for unallocated space
  
• Bitlocker is disabled
  
• Disabled secure boot and fast startup
  
• Boot from UEFI USB Ubuntu
  
• Install alongside Windows Boot Manager
  
• Partition: choose the default installation instead of manually partition (Using manual partition did not detect unallocated space)
  

I have 2 storage, SSD (Windows/ Disk 1) and HDD (Several Windows programs and data/ Disk 0). The HDD storage has several partition;

• Local Disk D: 510.82 GB for some applications
  
• Local Disk E: 225.37 GB for data
  
• Unallocated: ~195 GB
  

Even though it works perfectly fine, I'm afraid it will cause issues in the near future, and i want my linux partition and windows data partition to be shown in disk management. Can you please help me on this issue. It also shows Local Disk D and E which has windows applications and data to have red x indicator in disk management.





My idea: my current solution is probably to delete volume for Local Disk D and E to delete Ubuntu and delete several data I have in windows to reinstall ubuntu back using manually partition. However a second opinion or more can be my consideration to not delete my file in windows.

Thank you for your attention

 

Delete my W10 Partition

Do you want to safely delete your Windows 10 partition and use only Windows 7?

If Yes, then boot to your Windows 7, run msconfig, go to "Boot" tab, you will see something like this :





Choose "Windows 7" and click "Set as default", then choose "Windows 10" and click "Delete", restart if asked or necessary.
Now the boot information for Windows 10 has been deleted and you can safely delete your Windows 10 partition (make sure no important files are on the Win10 partition). To delete and extend your partition you can use many partition manager tools.

 

WIN10 Repairing bootloader after deleting second Ubuntu partition

I had my system set up with both Windows 10 and Ubuntu. I decided to only use Windows on this PC and deleted the Ubuntu partition, thinking I could just boot up Windows afterwards...

There are many tutorials out there that I tried, but nothing helped. I KNOW that a clean install would solve my problems, but in my case i would have a whole lot more problems because I have many programs through my university and it would be a real pain to set them all up again.



I tried to follow this guide: Tutorial

It works until i get to "create partition efi size=100"

The message in cmd is: "MSR and Efi partitions are only supportet on GPT disks. Convert the selected disk to GPT and try again"

I don't want to mess up even more so your help would be greatly appreciated!
