I have a friends TOSHIBA Satellite Pro L500 running win7 32bit. It has this boot up problem I have not come across before. When it boots it stops at the screen with F2 for setup and F12 for boot devices and goes no further. F12 brings up the boot device menu and when the HDD is selected the windows boot menu appears safe mode etc, I need to select 'start windows normally' which it then does.

I have tried 'startup repair', updated bios, deleted partitions and did clean install of the OS and also tried a different HDD. Nothing works.

I don't think it is a BIOS virus because no messages appear. is the ROM damaged?
