Start windows 10 Setup from a different folder

Doesn't work. Tried it. The Windows setup will give you the message the installation can't find drivers (load driver error). The Windows 10 setup ISOs must be extracted to exactly the root of the USB drive and the folder structure must be retained exactly. And you can't add extra images to the install.wim files either - at least not an insider build image any way.

One solution is if we use a different partition for every windows installation so we can avoid conflictions.
But my main problem is I already have 2 partitions (ext4) for linux distributions and 1 partition (fat32) for my PS2 Console.

So my final purpose is every windows setup can run in every system with bios technology (without UEFI).

According to MBR table we have the possibility to create only 4 primary partitions or 3 primary and 1 extended and inside this extended partition we can create other 4 primary partitions.So the maximum number of partitions we could have with MBR table is 7.

So I want to create a larger (NTFS) partition (to store data) and a smaller (NTFS) (to have all my Windows Setups) in order to have the possibility to create an other partition if I have to.

Sound really complicated. This isn't just a 4-in-1 is everything-in-1. I thought you only tried to make a Windows installation media. Adding Linux and other stuff complicates things.

My goal would be Windows 7, Windows 8.1, Windows 10 RTM, and Windows 10 Insider on one USB bootable with or without UEFI. I'm going to try the partition idea after work today.

I cannot imaging right now how this is possible otherwise, but the rather tedious method I described allows in theory to install everything from Vista to 10 simply by giving the correct syntax at the imagex utility. After Windows Setup files are extracted on the disk, you reboot the computer and Windows Setup takes it from there. It is basically if having done the first step and you are at second stage after the first restart.
