Hi all...

I have a problem with the computer not booting from the hard drive, where as if I look at the BIOS setup the hard drive is recognized.
I'm using a motherboard from Asus H110M-E M2

thanks for advance

Given the situation reported by — the Asus board sees the disk in BIOS but the OS partition is missing — the priority is to avoid further writes and treat the drive as potentially damaged or its partition table corrupted. The safest, most practical sequence is: create a sector-level image of the drive, run non-destructive diagnostics on that image, attempt partition recovery on the image, then repair the boot record only after the filesystem is coherent. This complements earlier points from , and while keeping the original media untouched.

A concise recovery workflow (from a Linux live USB):

  • Install required tools and make a raw image with GNU ddrescue (keep the log so the run can be resumed):

    sudo apt update
sudo apt install gddrescue testdisk smartmontools
sudo ddrescue -f -n /dev/sda /mnt/external/sda.img /mnt/external/sda.log
sudo ddrescue -d -r3 /dev/sda /mnt/external/sda.img /mnt/external/sda.log

  • Check drive health before heavy recovery work:

    sudo smartctl -a /dev/sda

    Watch for reallocated sectors, pending sectors or I/O errors — these point to physical failure.

Run TestDisk against the image (never write to the original if data is important):

sudo testdisk /mnt/external/sda.img

TestDisk can often rebuild a lost partition table. If that fails, run PhotoRec on the image to carve files.

If partitions are recovered and filesystems mount, repair the Windows boot environment from Windows Recovery (Command Prompt):

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

On UEFI/GPT systems use DiskPart to assign a letter to the EFI partition and then:

bcdboot C:\Windows /s S: /f UEFI

If SMART or ddrescue report many unreadable sectors, further DIY attempts risk extra data loss — stop and use a professional recovery service. To reduce future risk, maintain regular image backups and keep a small bootable rescue USB on hand.

Do you have a USB that you can boot from to check your hard drive? Linux Live or Macrium Reflect for example?

As I read your story, I wonder if you left out details such as this hard drive used to be in some other PC. Moving the Windows OS from one PC to another is not a sure thing.

@Reverend Jim, thanks for response

it turns out that it can't boot from the hard drive is the loss of the partition that already contains the operating system

Bless the lord

It's too late this time, but I suggest that when you rebuild your system you partition your drive as C and D where C is your OS and applications, and D is all your user files (you can move special folders like My Documents, etc to D). Then install the free version of Macrium Reflect to C. Create recovery media from within Macrium and make sure to create a boot image and a boot USB.

I presume you are doing backups to removeable media. If not then shame on you.

One last comment - you might want to have a look at a program called spinrite in case there are files you haven't backed up. It could possibly aid in recovery.

You probably have something wrong with your hard drive, and you need to see a professional. I recommend you go to salvagedata.com. They don't charge much for their services as far as I know. Don't worry; you might even have a problem installing windows correctly or need a BIOS setup. In short, you urgently need to contact the experts, and I hope that my post will help you solve your problem.
