a. Use the easybcd configuration file

b. It is best to add the reboot command to facilitate restarting when the file cannot be loaded or an installation error occurs.

title Install Ubuntu

root (hd0, 0)

kernel (hd0, 0)/vmlinuz.efi boot=casper iso-scan/filename=/ ubuntu-14.04-desktop-amd64.iso locale=zh_CN.UTF-8

initrd (hd0, 0)/initrd.lz

title reboot

reboot

title halt

halt

The file c.cvmlinuz is called vmlinuz.efi in the 64-bit ISO. Remove the suffix when using it, but it doesn’t seem to be removed. It's okay, I've tested it, but I don't know why some people say it must be removed.

d.Win7X64 uses GPT partition, and the system will have a 100M system reserved area, so the configuration loading address in the menu.lst configuration file should be (hd0, 1).

e. Just select the C drive where you want the image file to be copied. Some people say that you must put a copy in a Linux-based disk, but it is not necessary.

f.Win7X64 GPT partition signature will also cause a problem that your Win7 partition cannot be recognized, so you need to execute sudo dd if=/dev/zero of=/dev/sda bs=1 count=8 seek =512

g. After restarting and booting Ubuntu with NeoGrub, before clicking to install, you need to execute the command sudo umount -l /isodevice. The -l here is the lower case of L, and there is a space between -l and /isodevice.

h. When this interface appeared, I thought the installation was complete at first, but it turned out that it was not installed yet (which was very embarrassing) and I needed to click to install.

i. Now it’s about partitioning, it depends on the situation...

j. The disk format for installing Ubuntu can be ntfs, which seems to be automatically modified during partitioning.. .

k. After the installation is complete, you must remove the easybcd boot program. The Ubuntu program itself will have a selection interface, otherwise you will have to choose it once when entering Win7.

Problems & Solutions

a. When the filesystem type is ntfs problem occurs, there should be a problem with your menu.lst file. Nine times out of ten, the problem is (hdd0, 1).

b. After entering win, I accidentally installed the Ubuntu disk format, resulting in the inability to enter win7. Many solutions on the Internet seem to be ineffective. Anyway, I am WINPE. Repair tool repair.
