Win7 and Ubuntu dual system on Acer p236

1. First Acer p236 support UEFL boot, but can be turned off in the BIOS setup, otherwise it is cumbersome to install dual systems.

2. In addition, the system should be installed through the UEFL, so must be replaced.

3. Use the Windows installation disk to enter the installation interface. The default format for disks is GPT partitioning. We're going to replace the MBR.

3.1 Shift + F10 open a command prompt

3.2 Enter Diskpart, use this command

3.3 Enter the list disk to view the disc information. Find a real hard disk based on disk capacity, as there may be your USB drive

3.4 Enter select Disk 0 and select disks 0 for the current operation. If your hard drive is not disk 0, then choose your hard drive

3.5 Enter clean to empty the current disk partition

3.6 Input convert MBR, converted to MBR partition

3.7 Exit after success

4. Normal installation of Windows 7

5. Normal installation of Ubuntu 14.04

6. Restart the computer and find it directly into Ubuntu without the boot menu

7. Go to Ubuntu,

7.1 sudo GRUB-INSTALL/DEV/SDA
7.2 sudo update-grub

8. Reboot, the boot menu appears, and the Windows option is found, but you cannot enter it after selecting

9. Re-enter the command line interface via the Windows installation disk. Enter Bootrec/fixboot repair Windows boot

10. Reboot to enter Windows. But there's a sound coming in here, and I can hear it coming into the system. But I can't see the picture. Start repeatedly and enter the system from the recovery mode. Not yet resolved.
