I'm not sure exactly how I overwrote it, but I was writing a floppy image to a floppy disk (using a USB floppy drive), and somehow I inadvertently wrote the floppy disk to my primary hard disk which I have Windows 7 Enterprise x64 installed on with Bitlocker enabled. Now when I boot, I get the error "Non-system disk or disk error." Is there any way to repair this?
I have made a low-level backup in case anything I try does further damage, and here's what I've tried so far...
bootrec /fixmbr
- didn't work, now it says "invalid partition table" when I try to boot.bootrec /fixboot
- didn't work, command returns "element not found."bootrec /rebuildbcd
- didn't work, command returns "Total identified Windows installations: 0"
UPDATE:
After running bootrec /fixmbr
I used diskpart
to recreate the partitions and assign drive letters to them. I was then able to use repair-bde D: R: -rp 123456-*
to start recovering the files. It's still trucking along at the moment, so we'll see how it works out tomorrow.
