Windows 7: Boot Disk failure

Boot Disk failure

Hi All, enjoy the summer. I need some help please. For some reason 3 days ago I got the boot disk failure message. I have noticed that after doing the bootrec.exe all commands, and easyBCD all commands as in here : Nothing fixes the problem. Here is the curious part there must be a software switch that tells my Win 7 64 bit that windows is on drive D: as opposed to C:. Win7 or any other windows were never on drive D:.Win 7 is on Drive C:. Also while this is gone on this same switch makes the partition on D: active and says boot in Windows Disk manager. Scanning with Bootrec.exe with the scanos switch shows 0 Operating system. I have 3 internal hardrives C: D:and E:. All have only one partition. The windows Repair environment (RE) repair computer from starting does run but does not fix the problem. It also does not show a operating system to repair. Here is a hint I think, if I put the Win 7 install CD in the CD player and reboot when it says press any key to boot from CD, I DO NOT press any key and the computer boots just fine every time. So it must load a boot command from the CD even though I did not press any key I just let it go on. I would like to fix the problem but where is the wrong software command that tells my win installation that Windows is on drive D:. How to get to the boot manager? Your help would be much appreciated. Regards Peter

Whatever, first of all unplug the other two HDDs from the SATA ports before starting troubleshooting, because that is a must in this case.

Now, with one HDD containing one partition only. Are you sure that there is no 100 MB hidden system reserved partition there? Make it sure. If it is there, mark it as active. Otherwise make it sure that the partition on the HDD is marked as active. Partition - Mark as Active

Now, run Startup Repair for three separate times, with restarts after every single run.
Startup Repair: Run three separate times.
Now try to boot to the computer. Dont plug in the other HDDs till now. Does it boot?

If still it does not boot, test the HDD with Seatools for DOS, to make it sure that the disc is not failing itself. SeaTools for DOS and Windows - How to Use

Let us know the results.

Thank you Gentlemen for your help. I went back to EasyBCD and ticked the box Change boot disk. C: was already highlighted so I clicked on perform action and all is well. Thanks again for your help. Repair installing Win 7 did not help solve the issue. I still don't know what caused the Boot disk change that caused the problem. Oh well the mystery of digital codes. Regards Peter
