1. Select grub for Ubuntu, go to Grub, and select Install ubuntu,load mirrored file ready to install
2. Before clicking on the installation, select sudo umount-l/isodevice, the-l option is lazy uninstall, wait until you need to modify the partition table, can not have mount partition exists, enter this command will automatically uninstall the partition that hangs on the/isodevice node
3. Hard disk partition, because the extended partition can only have one, and is continuous, so the d,e disk behind the C disk is a logical partition, so Ubuntu needs logical partitions and primary partitions, only the logical partition, after the disk expansion partition.
4. Preferably at least 4 partitions for Ubuntu,/partitions,/boot partitions,/work partitions, swap partitions
If there is a/boot partition, Ubuntu is installed to the/boot partition, otherwise Ubuntu will be installed to the/partition path/boot;
5. Note Before formatting: Select Advanced, choose not to install grub to MBR, restart after Setup completes,
Note that sometimes you need to enter to confirm the restart process.
