How do you make a drive bootable that should already be bootable

How do you make a SSD bootable after cloning it from a working Windows 7 HDD? Every time I reboot the Samsung NP-RV510 laptop with only the cloned SSD, I get the same error message for the past two days: Operating System Not Found!

The reason I believe the SSD is not bootable, other than the error mentioned above, is because diskpart says it isn't. When I detail the disk, it says Boot Drive = No, but when I checked the original HDD earlier to compare, it said its Boot Drive = Yes. So based on that, my new SSD that was cloned from the HDD, should say the same thing, but it does not and I don't know how to force it to say "Yes". I tried GParted Live, though it apparently only flags partitions as Boot, not the entire drive as Windows seems to do.

Running the Windows Startup Repair is no help. When it automatically begins searching for Windows Installations, it always comes up empty, so I can't select one to work with. Yet, it always reports "Windows found problems with your computer startup options. Do you want to apply repairs and restart your PC."

Of course, I select yes for the repair, but then I get this error: "Failed to save startup options."

The details of the repair show that it would have repaired the {bootmgr}

And the following startup options would have been added: Name: Windows 7 Home Premium (recovered) Path: Windows Windows Device: Partition=D: (122001 MB)

Name: Windows Recovery Environment (recovered) Path: Recovery..long guid name..\Winre.wim Windows Device: Partition=D: (122001 MB) Copy of the current boot configuration data will be saved as C:\Boot\BCD.Backup.0001

The only thing that has never changed during all this time is the fact that diskpart still claims the SSD is not Bootable. Hence, why I think it may be the culprit to all this nonsense.

Any thoughts?

Thank You

From this website try the following:

  • enter Command Prompt option.
  • Press ENTER after you type in each of these commands which are not case-sensitive:
  • DISKPART (to open the partition utility)
  • LIST DISK (disk number(s) will be shown)
  • SELECT DISK n (where n is the number of the disk - probably 0)
  • LIST PARTITION (partition number(s) will be shown)
  • SELECT PARTITION n (where n is the number of the Primary partition you wish to make Active)
  • ACTIVE (the selected partition on the selected disk will be made Active)
  • EXIT (to exit DiskPart) EXIT (to exit the Command Prompt)

According to the website the active partition is the one that the computer will try to boot from so by making it active it will be selected as the boot drive.

Good luck

u didn't say what u used to clone, but I have never had a problem with Macrium Reflect Free imaging or cloning. Maybe it is time to try that.

I finally identified the culprit.

The issue was the BIOS was not completely detecting my OCZ Vertex4 SSD. It detected it on the general page so I thought all was good, but under the Boot page, it was not listed as my other HDD/SSD were that I tested. Not sure why this one particular drive was not 100% compatible with my BIOS or why it would be detected in part of the BIOS but not in the other. Anyhow, I used another SSD that was detected on both pages and then I used this stubborn Vertex4 in one of my other laptops and it works fine.

virtual disk service error: this operation is not allowed on an > invalid disk. the disk may be invalid because it is corrupted or > failing, or it may be invalid because it is OFFLINE.
