Windows 10: Install from USB partitioned drive?

Hi guys,

Wondering if anyone can tell me if this is doable. So I bought myself a 250gb m.2 sata ssd, and put it into the Silverstone MS09 m. 2 to USB enclosure to use as a USB thumb drive. My plan was to have a partition of around 10GB that I would use rufus to create a boot media on to do nice quick clean installs when I need to, another partition of around 20gb that will hold all my, notes docs exe files and other things I need after reinstalling windows, and then the remaining 200GB will just be my storage if I'm moving files around ect.
When I tried to create the boot media with rufus it says disk partitions W X Y will all be destroyed when I do this, and I cannot find a way to make it see partition X only let's say....
So really I'm asking is there any way I can do what I want to do, would creating boot media with rufus and then shrinking the volume to 10gb and repartitioning the unallocated space work, will Windows recognise this at all?

Thanks for reading my problem I hope I have been reasonably clear on what I'm looking for, if not I'm happy to provide more info if needed

Thanks in advance!

:)

 

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

USB Partitioning

Do you know the technical part of it? How does the flipping of the removable happen? How can we partition a USB without using a 3rd party software? Can you suggest any programming language? and what algo should I use? thanks!
