I'm helping a friend with their Surface Pro 3 with Windows 10 installed. A fake "Microsoft Tech Support" person enabled SysKey Startup Password so that they get a password prompt when they try to log onto their computer.
I've found some older articles that suggest using programs to disable Startup Password. To do so, I have to copy the hives from the infected computer over to a temp work area on a different machine, run the utility on the files, and then copy them back to the problematic machine. For example, see this article: SOLUTION: “This is Microsoft Support” telephone scam – Computer ransom lockout
I have been able to boot the Surface using Ubuntu 14.10 on a USB drive. However, I can't mount the C:\ partition. Here is the info from
/dev/sda4 1390592 489263103 487872512 232.7G Microsoft basic data
When I try to mount the partition, I get an error: "The device '/dev/sda4' doesn't seem to have a valid NTFS".
Is there any way to mount to this drive within Linux? If so, how? Thanks.
