Windows 10: Do I have extra hidden partitions

This drive is currently an SSD, but has been migrated from a spinner. The image goes back to Windows 7 and was upgraded to Windows 10 Retail, and I'm wondering if I have some hidden partitions that I don't need. I don't recall actually creating a recovery partition, since this system is home-built. There are a 100 MB partition and a 540 MB partitions that I'm not sure about. Note that one is FAT32 and the other is NTFS.

If I add drive letters to these partitions, what do I look for to see the purpose of each partition in question?

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Extra partitions

I have upgraded Windows 10 multiple times from previous builds to current 1903. I see multiple hidden partitions have been created over the upgrades, and read that most of these are Recovery partitions.

I know the first 450 MB one is the one created during the first install. Then the 490 MB one (second from the last) was created from the upgrade to 1803. The last 856 MB one was created from the upgrade to 1809 if I remember correctly (I guess so). When
I recently upgraded to 1903, no extra partition was added. I guess one of the three (or the last two) was used.

Among these 3 recovery partitions, how do I know which recovery partition is used for the current 1903 version? I wish to remove the two previous recovery partitions.

Thanks.

 

Uninstall problem


Open the Admin Command Prompt:

1. diskpart
2. List disk
3. select disk # where # is the disk that contains hidden partitions
4. list par
5. select partition #
6. delete partition OVERRIDE
7. repeat steps 5 & 6 for the additional hidden partitions.
8. exit

OR:
if you want to clean the whole disk, after step 3 above
Type: clean
