Windows 10: Safely partition SSD in Windows 10?

My laptop Acer Aspire 7 came with Windows 10 Home single language preinstalled on a 512 GB NVMe SSD.I wish to partition the SSD for work reasons. My auditing firm uses an ERP that has issues storing data and backing up data in the disk partition in which the OS is installed.I need to install either a second storage device or partition the existing SSD. The former is not an option for me right now. I plan on upgrading the storage a year down the line.So, for now, I need to partition. If possible, I want to partition in such a manner as to make C drive where the Windows 10 OS is installed 12

Partition SSD during windows 10 install

I'm assembling a new PC and running a fresh windows 10 install. I'd like to know how to partition the ssd into 2 separate partitions during the windows install (I'm using a bootable usb drive to install Windows).

I want to know if I need to input specific settings for those partitions or if it's all automatic?

I need one partition for Windows on and another for my documents. The ssd has 960gb size.

So I'm guessing it has about 60gb over-provisionning. I could leave out a bit more, but it probably doesn't matter that much

 

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

 

Saving free space on SSD (Regarding multiple obligatory partitions on main drive)

Gerry Here just copy-paste some irrelevant response.

Well, **I've figured it out**. Here my solution (I Take no responsibility from any damage that might arise from this process, and I do not guarantee it to work for u.)

We'll assume u have 2 disks; SSD and HDD.

Also NOTE: I Work in a GPT-Disk partitioning scheme, I don't know if it's applicable on dos-style MBR partitioning.

General-methodology wich we are going to work with (or TL;DR).

• Delete all partitions on all drive
• Install Windows on the HDD Drive
• Install Windows on the SSD Drive (yes, twice!)
• Repartition the HDD to free up and reallocate as we wish (The only parition that HAVE to be there is the EUFI System (Fat) )
• After freeing up HDD space, move user folder to the HDD
• PROFIT

And in more detail:

THIS GUIDE ASSUME THIS IS A FRESH PC - THAT U DO NOT HAVE ANYTHING U NEED ON EITHER DISKS.

* - Asterisk, not a real step, just additional information

• Boot into windows 10 installation
• Clear ALL partitions on BOTH drives
• Let windows install itself onto the HDD, We'll call this installation win-hdd
  • There is no need to actually boot into this OS.
• Boot into windows 10 installation
• Let windows install itself onto the SSD. We'll call this installation win-ssd
  • *What would happen now, Is that windows detects the recovery and eufi partitions and does not need to create such additional partitions on your ssd. It would only create a 16MB windows reserved partition.
  • *Your boot partition would be hdd/eufi; But since windows detect it's own bootloader it would allow you to duel-boot between win-hdd and win-ssd(default)
• Optional: During windows-ssd first run wizard switch to audit mode (CTRL+SHIFT+F3)
  • *We would use audit mode to:
    • * Optional1: Repartition hdd
    • * Optional2: Change "Users" folder to the hdd.
    • * If u do not want to move Users folder, u can do 6.2 After win-ssd fully boots instead
  • Repartition hdd & move Users folder:
    • Using a 3rd party tool such as "MiniTool Partition Wizard" you can do the fallowing *as you wish*:
      • Delete win-hdd partition
      • Delete recovery-hdd partition
      • Delete windows reserved (16 mb) partition.
      • You can also later move the EUFI to the start of the hdd disk, if needed
      • Create new partition (free to use) on hdd.
      • Make sure to properly assign drive letters to all drive as u wish
      • Fallow
        this guide to relocate the User folder (Starting from Step 2)
• Boot into windows-ssd; If u do not know which one (int the OS selection screen) It's safe to assume that the automatically-selected one is the win-ssd.
• If u have not performed 6.2 Yet, this is the time to do that now.
