In reply to Foxache:
There are a couple of issues. Windows backup and restore is noddy to say the least. You can basically only backup and restore that PC. If you change anything about it i.e. hard drive size etc, you will run into problems and certainly won't be able to expand the partition being restored.
There is a neat little freeby I use called Macrium Reflect which will backup and restore your PC and if you replace the disk, you can expand / shrink the restored partitions as you go along. I believe it can handle EFI and their associated GPT disks.

However, if you want to restore to a different PC you will need to splash out the $58 or so for the Pro version which has the redeploy function. It has got me out of trouble several times.
