In many cases, it is necessary to start its computer from a CD, from a diskette, for example during the restoration of Windows. Furthermore it is possible to get his computer in mode without failure to diagnose problems.

Start from a device

In certain cases, it is simply enough to insert the diskette, the CD in the reader. In the starting of the computer, the device will be taken into account.

In other cases, it is necessary to sometimes press on a particular key as Echap in the starting of the computer. A menu appears and asks us which device to use for starting.

Point out: Floppy means 'diskette '. Drive means 'reader ' as in Hard Drive (hard disk), CD-ROM Drive (of CD-ROM reader).

Start from mode without failure

The mode without failure loads background necessary for the functioning of Windows. He throws only the necessary equipment, the tools minimums. He is interesting for spotting problems and so allows to conclude if problem comes from Windows or from an installation or manipulation performed recently.

To achieve mode failure, it is necessary to press on the key F8 (this key is possible vary according to computers) during the starting of the computer. A menu allows to choose how to start the computer. In our case, it is by using mode without failure.

Once Windows were thrown, prove that everything works normally or perform required manipulations. Re-start the computer normally (Start / to Stop) and Windows will take responsibility in a habitual way next time.

Achieve in BIOS

The BIOS (BASIC Input Output System) is in programme thrown automatically as soon as the computer is put under high pressure. It is it which searches the equipment, proves their good functioning... It is interesting to sail in its options to prove material configuration and other technical options.

To throw BIOS, it is necessary to press on the key ' suppr ' (this key is possible vary according to computers) during the starting of the computer.

You will have then access to BIOS which is a basic programme therefore there is not mouse, windows... All manipulations are made in the keyboard. Pay attention to the manipulations which you perform at the risk of causing errors.
