I managed to do this with the DOS version but it didn't work because it's 32 bit. I think one possible solution would be to put the 64 bit Windows version of TestDisk on a bootable USB memory stick. One is for 'recovery' and seems to be okay and the other one contains my data which I want to recover. The computer's hard drive has two partitions (I think). While it was still somewhat workable I ran chkdsk and learned that a partition was labelled RAW. I have a computer that won't boot to Windows 10 or even to safe mode. I would appreciate any advice and please excuse my ignorance. I hope someone can help me with the following problem.
