prompter: When I turn my computer on, all I see is a black screen with this: 
"DISK BOOT FAILURE - INSERT SYSTEM DISK AND PRESS ENTER"
"No boot device available, press Enter to continue"
What should I do?

assistant: This message usually indicates that the computer is unable to find the operating system on the hard drive and therefore cannot boot. There are a few steps you can take to troubleshoot this issue:

1. Check the boot order in the BIOS: Make sure that the computer is set to boot from the hard drive that contains the operating system.
2. Check the hard drive for errors: You can try running a diagnostic test on the hard drive to check for errors. The exact steps to take this may vary depending on your computer's make and model, but typically you can access the diagnostic utility by pressing a key (such as F12) during boot-up.
3. Boot from a recovery disk: If the hard drive is not functioning properly, you may need to boot from a recovery disk or a bootable USB drive to perform a repair. You can use the recovery disk that came with your computer, or you can create a bootable drive using a program like Windows 10s Media Creation Tool.
4. Repair or reinstall the operating system: If the above steps don't work, you may need to repair or reinstall the operating system. To do this, you'll need to boot from a recovery disk or a bootable USB drive, then follow the instructions to repair or reinstall the operating system.

If none of these steps resolve the issue, there may be a hardware problem with your computer. In that case, you may need to take your computer to a professional for repair.

prompter: That seems to have worked, but when I started my computer it popped up a box telling me to "Restart your PC to repair drive errors", should I? Also, it seems like my folders where I store all my pictures is gone, do you think that might be related?

assistant: It's posible that data on your disk was corrupted. You should restart your PC to let your system try to repair filesystem and see if that helps. If it doesn't you can download an application designed to recover data like Disk Drill (up to 500MB data restore for free) or Testdisk (free). You can also contact specialized data recovery service but it's more expensive option.

prompter: Unfortunately the automatic file repair didn't work, can you give me a list of the best file repair software

assistant: Yes, if you're seeing a message to "Restart your PC to repair drive errors", it's a good idea to do so. This message usually means that there is an error on the hard disk drive that needs to be fixed. The repair process should fix any errors on the disk and help prevent further data loss.

Regarding your missing folders, it's possible that the files were lost due to the disk error that you're trying to fix. If the repair process doesn't recover your files, you may still be able to recover them using data recovery software. However, it's important to note that data recovery can be a complex process, and there's no guarantee that all of your data can be recovered.

In order to prevent data loss in the future, it's a good idea to regularly back up your important files to an external hard drive or cloud storage service. This way, if something like this happens again, you'll have a copy of your data that you can use to restore your files.

prompter: I have no backups

assistant: It sounds like your hard drive may have some errors, so it's a good idea to restart your computer and run the repair utility. As for your missing folders, it's possible that they were deleted or corrupted due to the hard drive errors. You can try running a data recovery program to see if you can recover the lost data.

prompter: Was I hacked?

assistant: There are many cases where you get this message:
1. There is no operating system installed.
2. The system is corrupted.
3. There is no system storage connected with a valid operating system.

Among other options. Please check if any of those options are aplicable to you so I can help you further.

assistant: The error "DISK BOOT FAILURE - INSERT SYSTEM DISK AND PRESS ENTER" "No boot device available, press Enter to continue" means that the BIOS is unable to read the designated boot disk. This can be caused by a corrupt hard drive, damaged hard drive, or a faulty data cable. One way to troubleshoot a boot disk error is to insert a bootable Windows Recovery USB drive and reboot the machine. From the Windows Recovery menu, select the Command Prompt option. In the Command Prompt, list available disks using the command `wmic logicaldisk get name`. Run `chkdsk` on the suspected bad drive to attempt a disk repair. For example, if the C: drive is suspected to be faulty, run `chkdsk /r C:` in the Command Prompt, hit Enter, and hit Y if prompted to continue. This process may help diagnose the issue, but it is possible that the drive may require formatting and reinstallation of the OS if the data is corrupted.
