Operating system not found on my acer v5 laptop

[Ivan Ancheta]

My laptop keeps on failing to boot up and says operating system not found or sometimes a blue screen error 0xc0000185 or sometimes another error. I forgot the name and i didnt took a screenshot of it. Restarting it by ctrl alt del does the trick and boots up. But it takes a lot of times doing it. I did a refresh on my laptop. Did a sfc scan. Tried changing uefi to legacy. But still this problem shows up. And right now. I tried like a thousand times doing ctrl alt del and still it doesnt boot up. But i can boot into safe mode. I just dont know what to do from there though. Please help me out. Is my hdd failing or do i need a complete format? My laptop didnt have a cd when i bought it. Also there was a time when i checked the bios it didnt detect my hdd. But that only happened one time. Ive been experiencing this for a couple of months now. Almost a year i think. But didnt decide on asking here since ctrl alt del does the trick. But now i really want to get rid of this. Im running windows 8 btw

[Moderator addendum: OS = Windows 8]

hey already ran the test. but not on safe mode cause my laptop worked this time. it finished the extended test and it pass with a correct mark on it. what to do next?

 

[ffg7]

the test was to check out your hard drive. do you mean a check mark instead of correct mark?

 

[Ivan Ancheta]

Yeah check mark. Lol. Do i still need to run it on safe mode?

 

[ffg7]

no.

 

[Ivan Ancheta]

What do i do next then? Having the problem again. So my hdd isnt dying? Probably a virus?

 

[ffg7]

have you tried resetting the cmos to default settings?

 

[Ivan Ancheta]

The one in BIOS? I tried restoring to default in BIOS f9 or f10 i believe.

 

[ffg7]

f10 is usually for saving any changes you did in the bios so that is not it.

 

[Ivan Ancheta]

Yeah thats not it. But i did restore to default settings my bios.
