Similar this question I potted rose-cuttings using the described in BBC's Gardener's World (cutting August-shoots in 20cm long "sticks" and place them into drained soil). I did this in the end of August and two of the stems started to build side-shoots. Not sure whether rooting has already started though.
What should I do to over-winter them (inside/outside, cover from frost, etc)?
EDIT: Not even one year later it flowers. It is not the same color as the parent. I assume that this is because of the plant not being really strong. The flowers look sadly because they have suffered a thunderstorm.
