How do you get bonded for doing computer repairs?
If you are talking about the insurance-type bonds, talking to an insurance agent specializing in business insurance should point you in the correct direction. Most of these are priced based on your income or expected income from the business.
To recover your operating system (this CAN be very simple to do) you must insert your recovery disc, that came with the computer, and follow the on-screen instructions. But doing this will delete ALL of the files on your computer that don't have to do with the operating system. If that doesn't work you either (1)take your computer in for repairs or, (2) you buy a whole new computer.
It's like insurance on you personally and a requirement in certain trades. You can lose your bond if a claim is made against it. For example a restaurant is robbed the night you were in there doing repairs- if you are proven responsible, you lose your bond and ability to get a license, they pay the amount of the bond towards the loss to the proprietor. .
