Having problems to boot my laptop HP 625 (can't even go into BIOS no key matching F1-F12), I think that my windows 7 partition might not be declared as active boot partition. Even booting from CD/DVD device with any kind of disk Ultimate Boot CD, Active Boot Disk, EASEUS Disk Copy or Windows 7 Installation DVD is not accepted. The only software working is the HP diagnostic tools. How can I start my HP having access to CHKDSK and DISKPART.

Thank You So Very Much For Some Help !!!
