Because the system crashes before using Win7 partition and unreasonable, so the direct reloading, here use Win10, my computer configuration is 512G SSD + 4T + Nvdia2080ti machinery + 32GB memory card, this is only the details need to pay attention to the installation instructions, not repeat all the details, in particular the complete installation has a lot of online tutorials.
## a. Install Win10
Use U disk to install, relatively simple, old peach installed download tool, online download Win10 to write a lot of online tutorials in this regard, not to say, a few points are worth noting:
* Install Advanced BIOS first boot mode to UEFI, the default is Legacy.
* Use the U disk into PE, with two solid-state partitioning tools DiskGenius hard disk format, using the Win10 attention GPT embodiment can improve performance, Win7 previously employed and the MBR, so attention first format is converted to GPT partition format and then the partition.
* Note 4K partition is aligned, remember to check the alignment of the following integer multiple. You can refer to [this blog] (http://www.33lc.com/article/27305.html).
Other installation process is not much to say, solid state disk installed Win10.
* After installation into the Win10 remember to choose SSDs C in Disk Management compressed disk, I have here the compression from the solid state in a 100GB, mechanical compression the 800G to Linux, not to carry out other operations after compression, reserved partition is unassigned state.
## II. Installation Ubuntu
Use Ubuntu official website to download Ubuntu18.04, and recommended the use of the official website of Rufus installation disk builder, U disk boot disk for installation, refer to [Tutorial] (https://tutorials.ubuntu.com/tutorial/tutorial-create- a-usb-stick-on-windows # 2). Note that point:
* When Rufus installation disk partition scheme production system type and target drugs selected GPT (no CSM), file systems FAT32, and then written to the mirror.
* Enter the BIOS before installing Ubuntu first SecureBoot closed, Fastboot closed.
* Boot prompt There are three options: "Try Ubuntu", "Install Ubuntu", as well as what not remember, where the keyboard to select press "e" to edit before installing Ubuntu, the "quiet splash -" here - deleted and replaced nomodeset, which is due to Ubuntu comes with the graphics driver is not compatible with NVIDIA graphics card, click on install does not set here will be black.
* Note that the installation process off the network, if the network is not very stable, otherwise the update package installation process will be very slow.
* Installed in the partition scheme selection to choose another time (someting else), define their own partitioning scheme, my partitioning scheme is:
& Emsp; & emsp; & emsp;. 1 EFI partition, solid, 500MB, logical partitions, so do not pay attention to UEFI way to start the redistribution / boot, Linux boot in EFI inside.
& Emsp; & emsp; & emsp;. 2 SWAP partition, solid, 16GB, logical partitions, was supposed to and consistent memory or memory twice, I think I memory is not small, it is symbolic assignment.
& Emsp; & emsp; & emsp;. 3 / partition, solid, reserved to the above two 100GB removing the remaining capacity of the partition, the file system EXT4, primary partition.
& Emsp; & emsp; & emsp;. 4 / home partitions, mechanical, EXT4 file system, primary partition.
& Emsp; & emsp; & emsp; online said they would choose Setup Manager position click Next, select the EFI partition on it, I have here is the default.
* Behind the installation is very quick restart after installation is to install U disk out, this time found boot screen boot of Linux, there are three options, the first is Ubuntu18.04, the second Ubuntu is Advanced Configuration The third is the Windows boot manager, select the third can enter Win10, the default is the first one. Ubuntu is also here to choose before pressing "e" edit first, in the "quiet splash -" - after as nomodeset, press F10 to boot into Ubuntu removed and replaced, because before, the graphics driver is not compatible, enter here will be Ubuntu Desktop , slowly self NVIDIA driver installation, the range is not described herein.
## III. To adjust the boot sequence items
Win10 want as the default first start, after entering the Win10 need to download Easy UEFI software, originally ranked third in the Windows boot manager can be promoted to first. The use of the GPT program, not to install EasyBCD, and useless, unless you are using the original MBR partitioning scheme.
To this end, smooth dual system, herein only brief details of the installation needs attention, pro-test can be used for one of these details do not understand the operation, may be used alone online search. There are many online blog posts argument is also inconsistent, so put together a viable and avoid the pit.
