flash two OS on a USB

[MeinGottWalther]

Hey folks!

Some time ago I installed a Linux based OS  on a usb drive to boot from and now I thought is it possible to have two bootable OS on a USB drive with enough space? If its possible, how can you do it, i mean which programs do you need?

 

I'd  appreciate the help!

You can, but then you need a bootloader to select between them. Look at something like unetbooting for a easy way to manage this.

Yes this is possible with multiply linux Live CD's on 1 USB. I actually did that once before but you will need some bootloader and multiply partitions. The last one can be a pain because Windows won't let you do this (Will only show one partition when using a USB flash drive). Maybe there is some tool for it these days.

 

Quick search got me this: http://multibootusb.org/page_download/

Maybe usefull to you?

I'd recommend WinSetupFromUSB, let's you add windows and linux quite comfortably

 

Uses Grub4Dos as bootloader, but you should be able to change that

Yes, its only on the USB. Any data still stored on the USB will be destroyed in the process though.

what exactly do i need to do now to install to linux OS? Do I need to create two partitions on the USB? which format? MBR or GPT?

.image files are the same as ISO containing the content of a device. Normally you would use such file by flashing it on a USB using refuse or dd command. Not sure how you would do that with multiboot tho.
