I've done that with a few of mine. My windows sp1 is on a flash drive along with a few others. If I do make disks I tend to make 2 copies of each just in case.
It's good that you sorted out the problem. DVDs can be risky.
As I said earlier it is best to use recovery partition on the HDD. This partition is easily imaged with free Macrium Reflect and reimaged if damaged. I reimaged my ACER recovery partition to a new replacement HDD and could do a factory recovery without any problem.
