I heard that windows vista and 7 require more space. Is it however possible to install it on a 8GB flash drive?

Could you also tell me what the minimum space requirements for Windows Server 2003, 2008 and 2011 are?

Windows generally refuses to be installed on removable drives because the licensing is tied to the hardware.  If you succeeded, it would refuse to run if you put it in another computer because the hardware wouldn't match the installation.

The USB would stay in the same computer, so I'm not worried about it not working on other computers. Would it simply not install in the first place? Wouldn't the installer see it as a SSD? is 8GB physically too small (I don't want to go into compression)

I don't see anything about running Win7 from USB like you can WinXP.  There are a lot of articles about putting the Win7 DVD on a USB drive and installing from it but not to it.

Apparently Win7 requires about 16GB after installation, 20GB for 64-bit.  Server 2003 : http://support.microsoft.com/kb/892807

I know you can install windows vista and win 7 from a usb stick but like others state to run the operating system off of a usb stick I doubt you would be given the option to install it on a stick. How abou trying to install it on a hard drive and then use a ghost or image software to install it on a usb stick. That probably would not work either but I never tried it before.

I tried to install Windows 7 to a 8 GB USB drive, and it was too small. You will need at least 16 GB.

I agree with DaveBaldwin: installing windows on flash drive violates EULA...you might end up with activation issues in future.

A volume license or evaluation license might be okay. Would need to read the fine print.
