How can I make two windows boot partitions and a data partition out of a single usb drive?

I have a 64GB usb stick that I carry on my key-ring. Right now it has only a single partition with all of my portable data on it. I don't really need 64GB of file storage, and I want to start carrying a Windows 10 install disk as well. Rather than carry two usb sticks with me I want to use the extra space on my current one. Looking ahead at the upgrades I'm going to have to do for family in the next few weeks, I've decided I should have 4 partitions, and for simplicity I've made them all roughly 15GB. Here's what I want them to be:

1. The first partition should continue to be my data files. I have around 5GB of data now, so 15 GB should be plenty of storage.

2. Windows 10 installation media, both 32-bit and 64-bit.

3. Windows 7 Universal installation media.

4. The final partition can be smaller, but I want it to contain installers for common programs (chrome, malwarebytes, adobe reader, etc).

I have created the 4 separate partitions on my usb drive, and I have the iso file for Windows 7 All In One. I downloaded the 1803 Media Creation Tool for Windows 10, but that's where I run into problems. I can run the tool and tell it to install to a specific partition, but it instead erases all partitions on the drive and creates a new 32GB partition that I can't shrink.

Is it at all possible to have 2 bootable (not at the same time, obviously) partitions for windows files AND a separate partition for data?

you want to have your USB windows 10 & windows 7 install stick all in one ? curious idea. I just use 128GB for data, 64GB for windows install and utils and 32GB for windows 7 and utils for installs... usb drives are cheap a dozen....

but back to your idea... you would need to create all 4 partitions ahead, 16GB for data, windows 10 install needs 4GB so give it 6GB, so does windows 7, that 12GB just for that. 16GB for primary data and that leaves 36GB left on that drive for utils.

I never have though of attempting this, and I can see possible issues, the partition where you install windows 10, would have to be using an ISO and installing it with RUFUS.


I have split a 16GB USB drive in 2 8GB partitions F ans G just to see how ell...

I have split a 16GB USB drive in 2 8GB partitions F ans G just to see how ell it would go, using MS windows 10 ISO from web site and Rufus 3.1 setting it to MBR so Target system can be Bios or UEFI (can leave it to GPT if you only deal with UEFI systems) it warns about possible data loss due to multiple partitions and I monitored the status of my partitions under windows computer management during the process. once it was done copying the iso over the result was... you cannot specify a particular partition to use to install it on the usb drive. remember it is not INSTALLING windows OS, it is Installing the INSTALLER for Windows OS.

the answer is not the one you want to hear, but the most practical one... get 2, 8GB USB drives and get windows install respectively on each them, and use the third for your data.... its how I have mine setup.. but thanks for the food for though .

maybe one day windows 11 will be a live cd install :)

What he said.
A couple of small USB's, linked together with a ziptie.
Done.
 
damnit it and now you got me thinking about weird ideas.... considering to use a usb to sd card adaptor, the sd cards are tiny, they make 4 cards wallets holders for them, makes it simple., though not as quick as a USB3 chip drive, an options, and 8GB SD cards are like 3 for 8$ dirt cheap, food for though, in a totally nerd like though... much like the one of 16 sd cards mounted on a PCIE card to make your own SDcard-SSD Drive. fun idea, but concept... not so much
