|If it will not boot into any of the options shown when you press F8 : Safemode, Last good config etc then recovery will require an XP install disk so you can do a repair install. |
Since you were partitioning the drive when the power was cut off there is every likelihood the partitions & file structure are toast and a full drive wipe will be required.
In any event you need a bootable CD or floppy of some kind in order to at least examine the partition & file structure of the drive.
