yes you do.
you can format your drive from DOS, but once you do that you wont have an operating system and your computer will be useless.
Format all other drives instead of that conatain operating system
A brand new hard drive must be formatted for any operating system to recognize it. You should have some kind of utility program to format a new hard drive that came with your operating system.
There is no special connection or setup needed. You simply set the drive you want to use for the operating system to boot first in the BIOS, then install the operating system to the appropriate drive. During the install process, you may also want to format the other drive.
Unless you tell me the current format of your current data, your operating system, and something about your hard drive, I can not tell you how to transfer your data.
You Format the Hard Drive then re install a operating system
Yes it will, but it will also remove EVERYTHING on the drive; your personal files, settings, programs, even your operating system. Don't attempt to format your hard drive unless A) You are prepared to loose everything on the drive AND you have experience installing Windows or another operating system. B) It is a secondary drive (such as an external hard drive) which has no system files AND you are prepared to loose everything on the drive.
yes all hard drives must be reformatted before installing an operating system.
There is no uninstaller for an operating system. To remove an OS, simply format the partition that holds the operating system. If you use a boot manager to choose between different operating systems the software should automatically detect missing operating systems for you.
In order to completely wipe a hard drive on a Canon branded copier, one must format the hard drive. Formatting the hard drive will erase all information. The operating system of the copier can then be re-installed.
my advice is just back up your files and re format the hard drive, and reinstall the operating system.
