If you don't have a DVD recorder and want to install Vista on a single system, you can put the installation file on the mobile hard disk and start the computer to install vista from the mobile hard disk! In this way, the installation effect is the same as that of the boot installation from the CD.
1. activate a hard disk partition with sufficient space under XP (in "disk management" under computer management, right-click the required partition and choose "mark the disk partition as active ");
2. Use daemontools to copy all files on the disc to the mobile hard disk;
3. Run X: \ Boot \ bootsect/nt60 X: (x is the drive letter of the hard disk partition) at the command prompt of XP to make the mobile hard disk a bootable partition.
4. restart the computer and set the first boot to USB boot in the CMOS settings;
5. Use the mobile hard drive to boot smoothly and start to install Vista. This process is the same as the CD installation. You can format your c disk and install it as a single system.
