[SOLVED] My lenovo G580 is stuck on bootmgr missing.

[imbhaskar]

earliar my laptop was running on win 7 but today it was not booting and was showing error like BOOTMGR is missing.so i tried to reinstall win 7 but it was showing error like
0x80070570 and then tried to install prime os and it installed correctly but when i restarted it is not booting.
so for now it's bios not opening,not booting from bootable usb.is there any fix?

You might want to see if the primary boot device(storage) is working. Try using the storage device on a donor system. Can you get into BIOS upon initial bootup?
