1. To do so, reboot your computer with the installation CD or DVD (see Section 1, “The Mandriva Linux Installer”).

2. Choose the Rescue System option.

3. In the new menu that appears, choose the Restore Windows Boot Loader option, then press Enter to write the MBR with a Windows ^® one.

These are usually partitions hosting ext3 file systems and the Swap partition. You can also replace them with a single partition using fdisk.

1. Still in rescue mode, select option Go to console.

2. Run fdisk /dev/sda (if the hard disk containing Mandriva Linux is other than the 1^st disk, change /dev/sda accordingly).

3. Use the p command to display partition information, and then use the d command to delete all unneeded partitions.

4. If you want to create a single partition, use the c command, specify 1 as the partition number, make it use all of the space available, and when asked for the partition type, use the L command to list the supported partition types and choose the one for the OS you plan to install later.

   Some examples:

   • c for a FAT32 (Windows ^® 9x) partition

   • 7 for a NTFS (Windows ^® NT/ Windows ^® 2000/ XP) partition,

   • 83 for a GNU/Linux partition.

5. Finally use the w command to write changes back to disk.

Once this is done, just reset or shutdown the machine using the corresponding buttons.
