The linux cd cannot restore windows. You will have to use the windows cd to do a repair install and then use the ubuntu cd to install ubuntu.

You can't do a Windows System Restore with a Linux CD, you have to be running Windows to do it. (And that just restores the registry.) The first thing you have to try is a Windows Repair (with the Repair disk). If that doesn't work (or if you don't have the Repair disk), do a Windows upgrade with the Windows install disk. (If you don't have any Windows disks, there's not much you can do.)
Ok, all you need is a windows bootdisk, you damaged your mbr by playing with your boot splash. You can download one from bootdisk.com, get a windows 98se, or if you have the windows cd boot to that and select repair console, then run fixmbr and fixboot.

If you use a boot disk (floppy), run fdisk /mbr, that will repair your master boot record (mbr).
