Useless video

HP Elitebook 840 G3 keeps entering factory recovery. I have reinstalled OS, replaced SSD, updated bios, set bios factory defaults. But it keeps doing that. I think it starts before windows booting. But if I choose "windows boot" on boot settings (F9), windows boots normally.

What else I can do to fix this?

Thanks for being so detailed, this video was really very helpful

Hi, my pc started giving me this error after a corrupted mobo issue, I installed a new mobo and it worked properly for about a week. It then blue screened earlier and now it’s giving me this issue. Any idea on what it could be?

hello,my computer is hp Pavilion laptop 15-cs3xxx,it always have the problem of "operation system not found",how to solve it😢？

@PC_Monkey, I would like to share my experience with my HP Spectre Convertible 13. When it was still under warranty I spilled some clean water on the keyboard and had to send it in to HP for repair. When I got it back, I didn't realize/associate it until later, but I had physical connection problems on my laptop: my USB-A port on the left side no longer works. And I started intermittently experiencing the "No operating system found" message when booting up. When I called HP they told me it was because my laptop had a conflict with the latest Windows 10 due to it being a few years old. No! I realize now that these super-compact, no access panel laptops are hard, even for HP, to take apart and put back together. I now believe this is why I am experiencing this problem. And if HP cannot take it apart and put it back together properly, I am not going to try! Lesson learned: think twice before you send in your laptop for repairs. These no-access panel laptops are very difficult to take apart and put back together. A slight gentle bang/tap on the right side is how I get my computer working again when I experience this problem.

What is "Short DST - Not Available"? I've fixed the date, and still ' Boot Device Not found'. I took the ssd out, and tested on the desktop, and it works fine. Making me dazzling. Thank you.

Thank you so much for the tutorial it really helped me 😊

Is it bad to load setup defaults in BIOS ?

My desktop give me the can't detect operating system error when ever I plug in a second hdd it does it on my HP desktop but not my Dell desktop I tired all sata connection but it still won't work what could be d issue with dat

i have a acer laptop but the escape allcthe way to f4 is out an dont work the only menu i get is f12 but it has no options besides emmc an network boot neither worked... also its a operation system not found

I ran the quick check on the hard drive but it keeps displaying smart check and long DST not installed. I reseated
the hard drive and tried quick check again but keep getting the same result.

I formatted my HP all in one PC, because Bitlocker was activated but I was unable to unlock, but know it didn't show the HD when I tried to install Windows 10 since a USB. I tested the HD, it's healthy. The installation starts but when it ask for a drive, just the USB appears. Do I need another bootable disk or what I'm doing wrong?

my computer is a windows 10 hp laptop my little nephew spilled water on the keyboard and now its just says boot device not found Please install ab operating system on your hard disk

Yea I think my drive might be dead, its been around 5 years. Probably gonna have to replace it.

It is recommended that you perform a BIOS update to the desired version.
