Not sure what you mean by a motherboard recovery CD, but the method to make a restore disk set, if Toshiba has that option, would be in the manual for your system. Or check in the programs installed for something from Toshiba, you'll know what it is when you see it.
If you mean mother board recovery CD as in a CD to "make motherboard work right," perhaps you mean a reformat and also all the drivers included. Most laptops should have a recovery partition on them, as Hang the 9 mentioned. Search up your model on google, find the correct key combination for "Toshiba satellite l300 windows 7 drivers." You might have to do a reformat from a windows 7 disk, then install the drivers afterwards.
