"UEFI+GPT/BIOS+MBR" two modes to install Ubantu system under Windows system

• Recently in Lenovo Windows10 installed the Ubantu16.04 system, stepped on a lot of pits, write down to share.

Through the network data, understand BIOS+MBR has been the previous computer Windows system installation and boot mode, but Win8 came out, basically used uefi+gpt mode. These two modes are a little bit different when installing the Ubantu system.

First, the WINDOWS10 system partition, the separate disk of the Ubantu system is delineated

Because I do not know what will happen to the security system, so it is best to separate a disk from other disks to install the Ubantu system, my f disk content is not much, so divided into half out, about 63GB size, can also choose 40GB or larger capacity. Here is a link to the tutorial.

Second, the U disk Startup disk production

• First download the Ubantu16.04 image file [other versions can choose], and then use the UltraISO software here does not detail this part of the content. Recommend a website, the blogger said very detailed (~￣▽￣) ~.

III. Installing the Ubantu16.04 system in UEFI mode

Other Ubantu systems are similar.

1. The general old computer is not UEFI option, depends on whether you have UEFI, need to enter the BIOS system [different models of notebooks into the BIOS settings of different keys];
   "My Lenovo Notebook is the first to press ENTER to activate (after the page interface is prompted), press F2 option to enter the selection interface, press F1 enter the BIOS setup interface, and press F12 to enter the USB flash drive interface]";
   Note: If the Lenovo ThinkPad set up a fast boot, it is not able to enter the BIOS interface, you need to [Control Panel-Power Options-Select the power button function-Change the current unavailable settings-Cancel the Quick start before the tick.

2. Two known ways: ① General notebook, such as Lenovo, in the BIOS interface switch to the [Boot] column, [UEFI Boot] Press ENTER to set the Enabled;② Lenovo ThinkPad notebook needs to switch to [Startup] column, will [Uefi/legacy Boot ] set to [Both], then set to [Uefi first], or set [Uefi/legacy Boot] to [UEFI only], "recommended to Both".
   "If not the above two cases, please contact the Niang (" the ")"

3. After shutting down the inserted engraved USB flash drive again, according to the model of the notebook Select the key to enter the USB stick boot options interface [Lenovo Notebook is generally F12].
   * * Note: Here's a question about USB drive recognition General USB Stick 2.0 and 3.0, and choose to start from the USB stick to see if your computer interface is supported 2.0 or 3.0; For example, the Notebook interface support 2.0 USB flash drive, but you plug in 3.0 of the U disk, in the selection of the USB flash drive will occur or can not find a USB flash drive or found the press [Enter] Problems that do not start properly and return to the selection interface. So, in this case, replace a USB stick try (￣▽￣) ~ * * "

"If still not, re-enter the BIOS interface, enter the [Boot] option, the corresponding USB flash drive to the first [general + number up,-# Move Down], and then into the U disk Start Screen"

1. After entering the installation process refer to the above link, here to focus on the * * Dual system UBANTU System Partition * * problem, in view of the dual system, limited capacity and demand is not particularly high, I generally divide five partitions "note is in Uefi mode":/efi partition (EFI boot partition),/ boot partition,/swap partition (Swap partition),/partition (root partition),/home partition (user partition).
   "All five partitions are built as logical partitions".
   ①/efi Partition Establishment: Size 1024mb[can also be smaller, 300M or the like]; format is EFI; The following name is selected as [/efi].
   ②/boot Partition establishment: size 300MB; format selected as EXT4; The following name is selected as [/boot].
   ③/swap Partition Establishment: Size 4096mb[can also be 1024 or 2048, if the required memory is not very large can be smaller]; format is selected as swap (swap space).
   ④/Partition Establishment: Size 20480mb[General 15~20GB, you can choose, according to their own ubantu total capacity of the size of view]; format is selected as EXT4; The following name is selected as [/].
   ⑤/home Partition Establishment: The remaining full size [user directory is the main working directory, generally a little larger]; format selection is EXT4; The following name is selected as [/home].

2. Do not click on the installation, the bottom of the page is selected for the EFI boot partition corresponding disk directory [such as: .../dev/sda8], and then continue the installation until the successful restart.

* * problems you may encounter when installing successfully with UEFI mode * *
"After restarting, the computer may lose Windows boot, and directly into the Ubantu system, you need to update the grub boot; don't be afraid of windows, but the entrance is temporarily gone (??ω??)? 】
"Enter the Ubantu system, press [Ctrl+alt+t] to open the terminal interface, enter [sudo update-grub] to update grub, then restart the computer, and if not, enter the BIOS setting [UEFI first] to [Legacy first] Try "

Iv. Installing the Ubantu system in the BIOS original mode

1. Without entering the BIOS setup UEFI option (seemingly without the 罒 ω 罒), go directly to the USB Drive launcher screen.
2. The other aspect is the same as the UEFI mode, except that partition without [/efi] partition, directly divided into four zones, [/boot] partition as the boot partition, the four extents in the same format as the top. At the same time, the lower section of the page selects the boot directory of the/boot partition and continues the installation until it is successfully restarted.
