So my friend got a problem. He wanted to reboot his pc so he shat it down, took out the battery for about 15 seconds, put it back and tried to load his pc. But after reseting the battery he got an error screen (american megatrand stuff) which told him that his boot order options are not presented. When trying to load from bios he gets an error that he is trying to boot from incorrect device so it is asking him to plug a correct boot device. At the same time, bios shows his HDD in load order but he cant boot from it. What could've happened? could his hdd die during that reboot? He tried changing sata mode from ide to ahci but it didn't make any difference.
 
Solution
No. Change boot mode.
For UEFI - boot entry will contain UEFI keyword or it will be named Windows boot manager.

There may be separate BIOS settings that allow
  • UEFI boot only or
    legacy boot only or
    legacy boot first, UEFI boot second or
    UEFI boot first, legacy boot second.
Boot settings have to be restored to same values, they were before reset.
This includes:
  • Sata controller mode (ide,ahci raid),
    boot mode (uefi or legacy),
    correct boot order (drive containing bootloader must be first).
Note - OS drive and bootloader drive may or may not be the same.

the thing is that all options expect his hdd in his boot order in bios are blank. In boot order priority window it shows no other options but hdd. So with hdd being placed at top of boot loader it still cannot load.
So if he has only hdd in his boot loader and has no windows boot option does it mean that his windows was erased from that disk or sth of that way?

what do you mean by changing boot mode? do you mean chaning sata mode from ide to ahci or something else?
