Question : Need to reinstall OS on a laptop

I have a T-1631 Notebook with damaged CD-ROM drive TSSTcorp CDDVDW TS-L632H (it wont read any cd'or dvd's )
the laptop is running the latest version of bios available (as far as I can tell), phoenixbios 90.03, a version that has no USB boot support.

The error at the startup is BootMGR is missing , Press Ctrl+Alt+Del to restart

My options are at this point:
1) Contact Gateway support (have submitted an inquiry just now)
2) Replace damaged CD-ROM with a working one. Not sure what models would suit set up that I have (T-1631 Notebook ). Maybe someone here can help me with that
3) Find out more about realtek boot agent (one out of three available options I have boot (hard drive/cdrom/realtek boot agent. Also hoping someone here could explain to me about this boot agent.
4) Move hard drive to another system and install OS

Of course I'd like to keep the files that I have on this laptop before reinstalling OS
