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

 

Windows 10: Unknown System (Z Partition or Disk.

Hi Leonardo,

There are several factors why you see unknown system partition or disk in your computer. It can be a recovery partition. For us to better assist you, we'd like to gather more information:

• What troubleshooting steps have you done so far?
• When did this issue occur?

Meanwhile, we suggest to follow these steps:

• Open a Command Prompt as admin.
• Type in diskpart.
• Type list volumes.
• Find out which volume shows as your drive E: then type select volume N, where N is the number that the volume was given.
• Double-check that you're on the right volume, type in "list volume" and check where the asterisk is. If it's beside the volume you wish to change, then good, if not you'll need to do "select volume N" again.
• When you're sure you're on the right volume, type in remove letter=E.
• Check it has been done by typing "list volume" to see the results.
• Close the command prompt window.
  

It will let you remove that partition.

Let us know if you need further assistance.

 

Recovery Partition vs System Reserved Partition

Thanks for all the info guys.

Both original & target SSD's are listed as MBR as opposed to UEFI. I may have created a partition unknowingly in getting the original/new unformatted drive recognized, but I don't recall taking any steps that Windows did not step me through.

Not that an upgrade to WIN 10 Pro is contemplated, but I suspect that having no System Reserved partition will not allow that to happen, after seeing how the original WIN 10 upgrade created a problem for some WIN 7 users that had a smaller 100mb vs 500mb System Reserved partition.
