A user may have problems dual-booting Ubuntu and Windows. In general, a Windows OS installed first Should Be, Because its bootloader is very particular. In general, the Windows OS must be installed first, because of its very special bootloader. A default Windows installation usually occupies the entire hard drive, so the main Windows partition needs to be shrunk, creating free space for the Ubuntu partitions. A default installation of Windows typically occupies the entire hard drive, so the main Windows partition needs to shrink, creating space for the Ubuntu partition. (You Should clean up unnecessary files and defragment the drive before resizing.) See changing the Windows partition size. (You have to clean up unnecessary files and defragment the drive before changing the size.) Add to resize the Windows partition.
After shrinking a Windows partition, Should you reboot into Windows once prior to installing Ubuntu or Further manipulating the partitions. After shrinking the Windows partition, you have to reboot once to Windows before installing Ubuntu or more manipulate partitions. This allows the Windows system to automatically Rescan the newly-resized partition (using chkdsk in XP or other utilities in more recent versions of Windows) and write changes to its own bootup files. This allows Windows systems to automatically search for new re-size partitions (using chkdsk in XP or other utilities in the newer versions of Windows) and write changes to the file itself bootup. (If you forget to do this, you later have to repair May the Windows partition bootup files manually using the Windows Recovery Console.) (If you forget to do this, I'll probably have to repair the boot partition of Windows files manually using the Windows Recovery Console .)
Newer Installations of Windows use two primary partitions (a small Windows partition and a large boot the Windows OS partition). new installation of Windows uses two primary partitions (small Windows boot partition and the partition of the Windows OS.) Also an Ubuntu Linux installation requires two partitions - a linux-swap partition and the OS partition. An installation of Ubuntu Linux also requires two partitions - linux-swap partition and the OS partition. The Linux partitions cans Either be two primary partitions or cans be two logical partitions Within an extended partition. Linux partitions can be two primary partitions or to two logical partitions in a partition. Some computer retailers use all four partitions on a hard drive. Some computer retailers using all four partitions on your hard drive. Unless there are two free partitions available (Either primary or logical) in the which to install Ubuntu, however, it will from Appear as if 'there is no available free space. Unless there are two free partitions are available (either primary or logical) in which to install Ubuntu, however, it would appear as if there is no free space available. If only one partition on a hard drive cans be made available, it must be Used as an extended partition (in the which multiple logical partitions cans then be created). If only one partition on the hard drive can be made available, should be used as an extended partition (in which multiple logical partitions can then be made). Partition management cans be done using the GParted utility. Partition management can be done by using the GParted utility.
If there are only two existing primary partitions on a hard drive (and plenty of free space on it) then there will of be no problem installing Ubuntu as the second operating system, and it is done automatically from the Ubuntu LiveCD. If there are only two existing primary partition on the hard drive (and a lot of empty space on it), then there would be no problem installing Ubuntu as a second operating system and it is done automatically from the Ubuntu LiveCD. Allow the Ubuntu LiveCD to install to "Largest available free space." Let the Ubuntu LiveCD to install to the "largest free space available." Alternatively, if there is an extended partition with plenty of free space Within it, the Ubuntu LiveCD will from install to this "Largest available free space" as well. Or, if there is an extended partition with lots of empty space in it, then the Ubuntu LiveCD will install it "the largest free space available" as well.
The main Windows partition Should Be at least 20 GB (30 GB recommended for Vista / Windows 7), and a Ubuntu partition at least 10 Gb (20 Gb recommended). The main Windows partition must be at least 20 GB (30 GB recommended for Vista / Windows 7), and the Ubuntu partition at least 10 GB (20GB is recommended). Obviously, if you have plenty of disk space, make the partition for whichever will from some of your larger Favoured operating system. Obviously, if you have a lot of disk space, which will create a partition for your operating system preferably is greater. For a recommended partitioning scheme, see this section. For the recommended partition scheme, see this section.
Conversely cans you install a retail version of Windows (but not an OEM or recovery version) after Ubuntu by creating a primary NTFS partition using GParted. Instead you can install the retail version of Windows (but not the OEM or version recovery) after Ubuntu to create a primary NTFS partition using GParted. (You May have to use GPparted from a Live CD / USB). (You may have to use GPparted of Live CD / USB). Once the primary NTFS partition is created you cans boot your Windows CD / DVD and choose to install Windows to That NTFS partition. After a primary NTFS partition is created, you can boot the Windows CD / DVD and choose to install Windows to the NTFS partition. When installation is complete, reboot to Insure Windows boots properly. After installation is complete, reboot to make sure the Windows boot properly. Once That Is ascertained, use the Ubuntu Live CD / USB to install GRUB to the MBR back. Once it is confirmed, use the Ubuntu Live CD / USB to install GRUB to the MBR. (This is Necessary Because Windows overwrites the MBR and designates its own bootloader as the master boot loader.) Once GRUB is installed you will from be Able to boot Either OS. (This is necessary because Windows will overwrite the MBR and bootloader appoint himself as the master boot loader.) GRUB Once installed, you will be able to boot either OS.

Wubi (Windows-based Ubuntu Installer), a dual-boot installer officially supported which allows Ubuntu to be installed at run-virtual disk in a Windows environment (which can cause some performance degradation). Because the installation requires an intact functioning Windows system, it is recommended to install Ubuntu in this manner for short-term evaluation purposes only. Because the installation requires a Windows system functions intact, it is recommended to install Ubuntu in this way for short-term evaluation purposes only. A permanent installation Should Be Ubuntu installed in its own partition, with its own filesystem, and Should not Rely on Windows. An Ubuntu installation remains must be installed on its own partition, the filesystem itself, and should not rely on Windows.
