My computer reads missing operating system

[Victor staggers]

My computer reads missing operating system... I tried repairing with operating system disc, but I'm stuck ! Help

You'll have to give more info than that for someone to help you. I'm guessing your getting the "No operating system found, please insert system disk" message on boot up? Is the BIOS boot order setup correctly? What exactly happens when you try to boot from your OS disk?

When I turn on my computer, it reads missing operating system. So I set my BIOS to check my cd driver first. I put in my windows 7 operation reinstall DVD. First I choose my language, then I get a option rather to install or repair... I click repair. But the next screen shows no system recovery options even when I select load drivers. I hope I applied more details this time, can u plz help

then

diskpart
list vol

I'm not interested in cd/dvd volumes. What do you see? Give me the drive letters that you see, and the sizes of the volumes. All are NTFS?

[Victor staggers]

The first one is UDF not VDF

 

[Kaktussoft]

Vol. 0 E WIN_7_HOMEP VDF DVD-ROM 5884 mb healthy Vol. 1 C RECOVERY NTFS Partition 14GB Healthy. Vol. 2 D OS NTFS Partition 451GB Healthy. Vol. 3 FAT Partition 39GB Healthy Hidden

Vol 0: DVD
Vol 1: Some RECOVERY partition from computer manufacturer
vol 3: fat partition I don't care about

So

[Kaktussoft]

diskpart

det  part
sel  vol  d

Which one is active?

 

[Victor staggers]

So what do I do from hear?

 

[Victor staggers]

What do you mean by det part?

Work with Kaktussoft to make sure your Win7 partition is marked Active then run Startup Repair - Run 3 Separate Times .

If you can't access System Recovery Options on F8 Advanced Boot Options, then you'll need to boot the installer or System Repair CD. Try Resetting the BIOS to defaults: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Then if required work through these Troubleshooting Steps for Windows 7 which try everything possible leading up to if necessary rescuiing your files to run Factory Recovery or Clean Reinstall.

You might be able to get Recovery to run by marking it's partition Active then rebooting. Of you can try triggering REcovery from its hotkey at boot. What is your PC make/model.

diskpart
sel  vol  c

Which one is active?

after typing:

I can reach the system recovery options, but nothing shows up in the box where it says use recovery tools that can help fix problems starting windows. There is another option which says restore computer using a system image that you created earlier.... When I click this option it says windows cannot find a system image.

Why don't you just do what I asked you to do? I just wanna know if volume C or D is active

When I type det part I'm getting a message saying there is no disk selected. Please select a disk and try again
