Windows 10: Confusing partitions on HDD

I have 2 HP laptops running Windows 10. The nice thing about having two is the ability to compare them when something looks a little off or suspicious.One of my laptops had a terrible time with upgrading to Windows 10 from 8.1 (Computer A). The other was very smooth (Computer B). Despite all the problems I faced with A (many failed updates, issues getting off , I did get it to the point where it was running fine and Well, as part of doing a series of backups to preserve data, I noticed that there are striking partition differences between these two machines, both running version 1803.

Computer A has 3 partitions -- WINRE (OEM), (*) (EFI System Partition), C: (Boot, Page File, Crash Dump, Primary Partition).
Computer B has 6 partitions -- WINRE, (*), EFI, (*), C:, I: (?), J*Sad?), D*Sadrestore)

On A:, the restore partition was removed because it originally contained Windows 8.1. Still, I don't understand why there are 2 additional partitions and what they could possibly be used for.

I'm going to install a new SSD for Computer B. Can I just take the first 3 partitions and discard the rest?

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

Hi Johan,

It is possible that your
