Bootmgr is missing [Closed]

Hello,
I'm desperately trying to find help about my toshiba satellite. My laptop got infected with a virus and I was trying to restore it factory default. My laptop came with recovery wizard and I burned it on a DVD. I've done this before and it worked fine. But this time I kept having error partway through that says "cannot read from the source file or disk" PREINST5.SWM.
Boot f8 don't work. Boot and zero but only works partway through and then it keeps asking to insert disk. I tried putting in the 2nd recovery disk that I have but it won't take it. It pops out the disk and continue to ask to insert disk to complete recovery. I can't access my laptop anymore.
I would deeply appreciate any help to get me through this problem.
Thank you very much.
