Running From Extreme 64GB Has Changed Windows On Local Drive

[shurimano]

This has happened to me twice now cloning Window 8.1 to Extreme usb 3.0 works 100%, however it seems when the space is getting low on the 64GB stick windows decides to use the paging file on the local internal drives & also changing the boot menu thinking it shouldboot from D drive & not drive C.

You said "changing the boot menu thinking it shouldboot from D drive & not drive C". I'm sorry, I don't quite understand what you mean. So could you explain it?
