I lose CDs, but for some reason I never lose the USB thing... I just... sorta... forget where it is, sometimes... *shifty eyes*
Not sure how you go about putting Windows 7 on a USB device, though... it was a long time since I did it, but I'm sure someone else here knows of it.
Here are the instructions for creating a bootable usb flash drive that Derp man was referring to...
Installing Windows 7 via USB or SD Media:
Insert your removable media into a Windows XP or Vista PC (or Windows 7 PC) and run the following commands from an elevated command prompt.
2. list disk (find the disk number for the removable media)
3. select disk #
5. create partition primary
6. select partition 1
8. format fs=fat32
9. assign letter=y (or any free drive letter)
Once that is complete put in the Windows installation DVD or mount the ISO (I use VirtualCloneDrive for this purpose) and run the following command.
xcopy x:\*.* /s/e/f y:\
Where “x” is the drive letter of the Windows DVD or mounted ISO. Once complete boot off the device and install the OS. When a new Windows 7 or 2008 R2 build is released, simply delete the contents, rerun the xcopy command and you are ready to go again. As a note this also works for Windows Vista and Server 2008.
