You need to boot from any fresh WinPE Live Cd to have access to laptop HDD (I'm use russian "alkid.live.cd.usb.full.2009.08.18" for that). After boot you will find a folder "$#repair" at Fujitsu-Siemens hidden recovery partition (Letter - D: in my case , Label - WinRe). This folder contain a file "SetAutoFailover.cmd" that is need for repair F8 recovery menu.
But first you need put to this folder two files "bcdedit.exe" & "DISKPART.EXE" (download from internet). After that run these commands:
cd D:\$#repair SetAutoFailover.cmd /target D: /wim /nohide
If it is run succeful after reboot you will see Fujitsu-Siemens Recovery Option at F8 menu on the top.
