If you try to perform a bootrec.exe /rebuildbcd and it can’t find any Windows installations, make sure you are using the command correctly
Tip: Also read our definite guide to fixing boot records
When that happens you should make sure you have the correct drive volume
1. Step Enter “diskpart” without the quotes
2. Step Enter list volume
3. Step You should now see all of your volumes
Try: Bcdboot D:\windows
If Windows is installed on another drive, you should use the command bcdboot before executing a bootrec.exe /rebuildbcd
Simply enter bcdboot D:\Windows
Then run the commands again:
Repairing boot records:
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /rebuildbcd
If you’re having problems, consider cleaning your disk using diskpart .. I explained this here http://windows7themes.net/fix-setup-was-unable-to-create-a-new-system-partition-or-locate-an-existing-system-partition.html
Black screen with this error message: Corrupt boot structure and BIOHD-4, had recently installed Windows 10 (6 months ago) there is no C:\ available best I can get is an offer to format the drive/ Any solution?
Christo, I’m afraid that your hard drive is broken beyond repair at this point. Try getting a 2nd hard drive, install Windows on it, then attach the 2nd drive to see if you can salvage anything
