The 32-bit version (-i386) will run on a 64-bit computer, but a 64-bit version (-amd64) will not run on a 32-bit computer. The Desktop version is available in 32-bit and 64-bit versions. The user should decide beforehand which ISO to download.
GRUB Legacy can not use this feature.Īll GRUB references on this page refer to GRUB 2 (version 1.97 or later) unless otherwise noted. In order to use this feature, GRUB 2 must already be installed on the system. In addition to Ubuntu ISOs, many other Linux distributions as well as popular rescue CDs can be booted directly from an ISO file. This feature permits the user to boot and use the 'Try Ubuntu' feature of the Ubuntu installation CD as well as to install Ubuntu directly from an ISO on the hard drive. Ubuntu ISOs are designed to allow booting directly from the hard drive using GRUB 2 and eliminates the need for burning a CD/DVD.
