As in the BIOS to enable the drive

First, assess the situation due to which your computer is having problems. For example, it worked properly, then the next time you turn ceased to boot, while in BIOS the disk is not visible. This situation is followed by DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER. That is, the system does not see the disk, and therefore is unable to boot.

Enter the BIOS by pressing at start-system Del or F2. The specific key depends on the model of the computer (may also be F1, Esc, F11, F12). Go to standard CMOS Features and make sure that the disk is not really defined – in this case, everywhere is the entry None.

In this case, "enable" , the disk will not work, as it is not determined at the level of "iron". That is, there is some physical malfunction: faulty itself drive, power Flex cable or data, possible fault in the motherboard. Inspect the diskand it can connect to another computer. Remember that a healthy disc does not need to be enabled, the system finds and determines it automatically.

You can face a situation when the system does not see the drivewhen installing the OS I receive the message that the disk isnot found. Problem is for laptops and older distributions of Windows in which there are no SATA drivers. The best option in this case – to find a new distribution where these drivers are present.

Changing settings in BIOS may be required when installing a new OS in that case, if there is no boot menu (usually by pressing F12). Choose the drivefrom which you will be downloading, in this case it is necessary in BIOS. Find the tab with the strings First boot, Second boot, etc. In line First boot install booting from a CD and save the changes – the menu item SAVE AND EXIT SETUP. Now the computer will start loading the OS from the CDdrive. Remember that when you install immediately after the first automatic reboot again to enter the BIOS and restore the original settings. Without this, will start again installing the OS from the CDdrive.

If the drive is visible in BIOS, but it does not find Windows, the problem is likely in the type of the file system. Below the disk is visible, it is necessary to format the file system type you use. For Windows XP and Windows 7 is NTFS. To format use Acronis Disk Director. Better to use the version loaded from the CD-drive. After formatting and restarting, Windows will begin to see the disk.
