boot up problem & bios in y470

[mrmf]

Hi
I had an ideapad y470 lenovo laptop. last night, I hibernated it & todays morning,
i encountered with this error, when booting up windows: "bootMgr is missing...press Ctrl+Alt+ Delete to restart."

 this error occurs after displaying  logo splash screen. i want to fix it by image DVD's of Win7 but access to bios setup was impossible and consequently i couldn't use "onekey rescue button" and fix problem.

Please help me.

thanks in advance.

how come you can not access bios? tried to use f12 to set bios order?

yes i used f12 , f2 , f1 but nothing doesnt work.

try this trick : remove the battery, un-plug the ac power, press power button for 30-40 seconds, replace the battery and check if the f2 or f12 works.

I tested it but it didnt work and there is still the same error.

it'd be better you to contact lenovo support line ( or local support center )
i don't think we'll be able to help you due to it could be hardware issue.
