1, the test is in a computer has two hard drives, operating system of the disk does not move, just clear another hard disk of the EFI partition. Start → run → input: Diskpart Click OK to open cmd.
2, then, Input: List disk Press ENTER (enter key) → Select the disks that need to be modified.
3, here is a disk 0, and then enter: Select Disk 0 back to the car to select 0.
4, Re-enter: Clean press ENTER (enter key) can erase all t
impossible with EasyBCD and pure grub1 realize double Kai simply impossible, we don't waste time. Online has said easybcd2.2 can realize, I tried countless times not. In the boot priority selection, legacy only, save restart, the long-lost CentOS interface appeared, that call an excitement. The lower arrow key selection Others,windows not go in. Anyway still a little happy, CentOS installed successfully, my confidence increases, through GRUB1, I think can start Win8, then I began to try to use
the bootloader ntldr/bootmgr-- > generates a multi-system boot menu based on the profile BOOT.INI/BCD and loads the corresponding system based on the path stored in the selected system and configuration file. (The so-called chained load, the master boot record is to find the partition where the system resides, i.e. the active partition) For UEFI start-up,the main process for UEFI+GPT is power-on self-test, scanning the storage device according to boot order, reading the FAT format of the
configuration Refind, boot directly into the Refind interface, but can not find the Linux system options (Refind will automatically search all the EFI files in the boot area)Second, directly into the CentOS, this situation is configured to restart the system after the Refind or directly into the CentOS, but you can press ESC (My Computer is ESC) to enter the system boot option, you can see the refind boot option, you can switch to Windows after you c
Ubuntu system,Using the DF command to view the partition, see that there is a partition for the EFI partition default to/dev/sda2, mounted in/boot,Use the command first$ mkdir -p /mnt/efi$ mount /dev/sda2 $ cd /mnt/efi/EFI/Boot$lsThis is going to see a bootx64.
The following is the entire process of booting the installation Windows8 in a UEFI way on a Lenovo Y480 notebook, and the installation Windows7 process is essentially the same. Note that if your computer hard disk is an MBR partition structure, all data on the hard disk will be deleted during the installation, please back up all personal files on the hard disk before installing.prepare a USB flash drive with a capacity of not less than 4G, formatted as FAT32. Then copy all the files from the 64-
beginning of the macOS, there are a total of five partitions, represented from 1 to 5, respectively. If the hard drive with the serial number contains five areas, it should be the serial number of our U disk. Here it is 0, and generally it should be 0.
If we want to enter the installation program for Windows, the number of this area is 4, enter set root = (hd0, 4) in the command line and press Enter.
Enter the location of the Windows EFI Boot program
32-bit, the UEFI section discusses only the x64 platform. The Itanium architecture is not supported because there is no experimental environment.

Next, go into a existing install of Windows R2 and copy the bootmgfw.efi file out of C:\Windows\Boot\EF I\ into the USB stick ' s H:\efi\boot\ folder and rename it to Bootx64.efi (not case sensitive). (And then find An already installed win2
the hard disk will be deleted during the installation, please back up all personal files on the hard disk before installing.prepare a USB flash drive with a capacity of not less than 4G, formatted as FAT32. Then copy all the files from the 64-bit WIN8 image to the USB stick root directory. Note: If you are installing a 64-bit Win7, you also need to download the Bootx64.efi file (click to download), and the

After the system starts, you can run the efiboogmgr command to view and modify the UEFI Startup menu. However, my own experiment proves that the modified menu does not take effect. Ano

use SSH to log On to the Ubuntu System of my laptop and how Wake On Lan is started, direct access to Windows is not acceptable, in the BIOS, WOL boot can only select a hard disk instead of a boot in EFI. As a result, WOL boot will go to Windows every time. Next, let's talk about how to operate the EFI partition more easily. In Ubuntu, run the command sudo nautilus in terminal to open the ROOT permission Fi
, it seems to be OK. Plus go after, and then excitedly restart. Results after reboot, press ESC, bring up the "Select Startup item" box, I found that there is no I just added. I don't believe it. In the boot entry of the BIOS, there is really no. But I saw the column with the Add boot. Thought, through the Easyuefi add is not successful, then I can add the BIOS to the total. Enter the name of the startup item, After finding the one I wanted as the startup item (I don't know if it was grub.efi or
the hard disk, enter list partition to view the number of each partition, enter select partition * (number) to select the efi partition, and enter the command assign to assign the drive letter. Install the software Total Commander and run it as an administrator to operate on the EFI partition. Back to the question, how to boot the hard disk directly into the Ubuntu boot. Copy grubx64.
Keep the original data as much as possible and establish a UEFI and BIOS dual-boot PE USB flash drive1, make sure that the USB drive or the mobile hard disk has a FAT32 partition, if there is no FAT32 partition, use the AO Mei Partition helper or ppm to convert an existing partition to FAT32 partition 0x0c, or create a new FAT32 partition, Then extract the UEFI-enabled Win8pe.iso to the partition.2, use Bootice to write the USB drive or the mobile hard disk MBR grub4dos0.4.5c, and then copy the
install Windows using UEFI mode.
Currently, 64bit Windows Vista, 7, 8, 8.1, and 10 already support GPT partitioned tables, while Windows 8, 8.1, 10 have native support for UEFI, when installing these systems: as long as the hard drive is set to GPT partition Table + motherboard set to UEFI boot, You can start installing the operating system directly.
For Windows Vista, 7 systems, you need to manually add UEFI support, we can find a copy of Windows 8 or 10 installatio
