Is there a Windows 7 Install from USB flash drive size limit?

I have a copy of Windows 7 Professional on disc (32 and 64 bit). I want to create an install on a USB memory stick in case the discs get scratched.

However, I am concerned that if I buy a large flash drive (64gb) then it will not
1) be recognised, because it is too large in capacity or
2) I will be unable to use any capacity beyond the .iso file for other storage

Any help is much appreciated. I have not yet bought the 64gb flash drive, but obviously the bigger I buy gets me more gb per £

3) If I need to buy a smaller USB flash drive, what is the minimum size I would need?



The minimum size required to create a Windows 7 USB download tool is 4GB.

Usually the USB size doesn’t matter when you download the setup files. You can also store other data in the same drive,

Hope the information helps.
