Hello,

My computer doesn't boot up anymore: automatic repair fails and none of the Windows 10 advanced recovery options work. The C: drive is listed as RAW. I'd like to use TestDisk to repair the partition/boot sector, however I'd like to confirm first which version to use in 64-bit Windows 10 cmd in boot menu. I tried downloading the Windows 7.1 version of TestDisk (not the 64-bit version), put it on a USB key and tried to run via cmd in the boot menu, but I got this error: "This version...is not compatible with the version of Windows your are running."

Could you please advise how to use TestDisk in the Windows cmd in boot menu? I think I can follow the step-by-step directions once I get TestDisk running.

Many thanks!

Use the Windows 64 bit version of TestDisk 7.1-WIP.
Read https://www.cgsecurity.org/testdisk.pdf for the whole documentation.

Many thanks, Christophe! Your help and quick response was much appreciated - I was able to start TestDisk as per your instructions. I accidentally interrupted the deep scan, but it seemed to have found the missing partion; I will run it again tomorrow. In the meantime, I got this message early on in the process: Warning: Bad starting head (CHS and LBA don't match). Could I still write/restore the partion? Or do I have to resolve the bad starting head issue first? Let me know if you need the testdisk.log and I can post it after the deep scan completes. Thanks again!

It's only a warning. If your partition has been listed, you can ignore it.
