You have important document files on the drive that are not backed up. What do you do first? Explain why this is your first choice. Try a data-recovery service even though it is expensive. Remove the hard drive from the computer case, and install it in another computer. Try GetDataBack by Runtime Software (runtime.org) to recover the data. Use Windows utilities to attempt to fix the Windows boot problem. Run antivirus software to remove the virus.
b. Remove the hard drive from the computer case, and install it in another computer. Because recovering the data is the top priority, you don't want to do anything to risk further damage to this data. The choice that is least likely to affect the data is removing the hard drive from the computer case and installing it in another computer. Then boot into Windows and try copying the data from the bad hard drive to the good drive. After you've recovered the data, you can use anti-malware software on the second computer to scan the hard drive for malware.
Which tool is the least invasive solution to repair Windows? System Restore Startup Repair Windows reset Uninstall updates
b. Startup repair Startup repair is the least invasive solution because it only repairs critical Windows system files, services, and drivers.
