It look like it's not booting into Windows anymore. You can try a Windows repair disc if you have one. Make sure you're doing the F10 correctly and that is you need to keep on tapping F10 right when you power on the unit. If it does not to into the recovery console/partition then there is something wrong with the hidden partition and it's no longer bootable. At this point you might need the recovery media discs. Here is the Sony Support website for your unit.
