Windows 10: Make Windows 10 installer use existing partitioning

Hello,


I have a GPT partition layout on my HDD which includes (in the order):

1. 511 MiB partition, type code 2700 (Windows RE), NTFS-formatted, intended for Windows Recovery Tools
2. 512 MiB partition, type code EF00 (EFI System), FAT32-formatted, intended to be an EFI System Partition
3. 16 MiB partition, type code 0C01 (Microsoft reserved), wiped and unformatted, intended to be a MSR partition
4. 97264 MiB partition, type code 0700 (Microsoft basic data), NTFS-formatted, intended for Windows 10 system
5. 16384 MiB partition, type code 8200 (Linux swap), used as Linux swap
6. 49152 MiB partition, type code 8300 (Linux filesystem), used as Linux system
7. 313100 MiB partition, type code 8300 (Linux filesystem), created to prevent Windows installer make it's own partitions instead of using existing ones

During the clean custom Windows 10 installation, after I select the 4th partition as a place to install the system I get a message "We couldn't create a new partition or locate an existing one."

Before the last partition existed, the installer created it's own recovery and EFI system partitions in it's place and then wrote something about "GPT disk partitions not in recommended order".


How can I make the installer use existing partitions from the layout (without any layout rearrangement) and NOT create it's own? Maybe I should change partition types/filesystems? If not possible, how can I later rearrange the installer's layout to mine?

:)

 

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

 

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

 

Installing Windows Vista/7 on a GUID Partition Table

I've never tried multiple partitions so this is a shot in the dark...

At step #10, I would try setting the size parameter (it is in mebibytes) to how large you want the partition windows is installed on to be, then go ahead and install windows. This will leave the rest of the drive raw instead of consuming it into the OS partition (C drive). Once you successfully boot into Windows, you should be able to use Computer Management -> Disk Management to create partitions in the raw space.


If you really wanted to do it with diskpart before Windows is installed, you basically repeat the following lines making sure to specify a size if you don't want it to consume all remaining space:

• create partition primary size=size in mebibytes here
• format quick fs=ntfs label="appropriate name here"
• assign letter=C thru Z here

Obviously, you can use quick formatting or leave it out for full format. Leave off the size parameter when you reach the final partition that should consume all the remaining space. Also remember that the order you do this in goes from the outside of the disk (where it is fastest) to the inside of the disk (where it is slowest). Because of this, it is recommended to put EFI (e.g. size=300), then MSR (e.g. size=300), then Windows (e.g. size=30000), then Applications (e.g. size=70000), then Storage (e.g. no size parameter).

If I'm right, the above example would look like this:

• diskpart
• list disk
• select disk <id>
• online disk
• attributes disk clear readonly
• clean
• convert gpt
  
• create partition efi size=300
  
• create partition msr size=300
  
• create partition primary size=30000
• format fs=ntfs label="Windows"
• assign letter=C
  
• create partition primary size=70000
• format fs=ntfs label="Applications"
• assign letter=D
  
• create partition primary
• format fs=ntfs label="Storage"
• assign letter=E
• exit
