I Googled your computer & it says F2 is for entering the BIOS.
You might try System Setup . That might be where the boot order is set up.
The Utility partition may be what your computer has instead of recovery discs.
I would take a look at that also.
If those don't help try F2 & see it there is a start up or boot order that is setable.
If the above two from F12 don't offer a way to use the recovery disc or possible "recovery partition " on the hard drive . Many times those are hidden.
Your CD/DVD drive has to be first in the boot order.
If you need to boot from the recovery disc.
