I m win8 booted ubutu s dual system.,But,Recently reinstalled win8.,Ubuntu system is gone.

If you want to recover, add a boot with easybcd, which is very simple.

Hide the drive letter and show it in the disk manager, delete the partition, and then rebuild it.

Answer: It is possible to form a dual system, and you can only install it like this (except for using Wubi under Windows), because the Windows system is booted from MBR, and Ubuntu is booted from Grub, if the order is reversed, it will lead to the installation first.

Install ubuntu first, and then install win7 passing by. But I don't have one more menu after the update, maybe two more every time I update it, and I haven't gotten it (.)

Win8+Ubuntu dual system boot start Ubuntu method is as follows::

1. The simple but stupid method is to delete the data in any one of the three disks of def after transferring. Select the last logical disk, because if the D disk is deleted, Windows is likely to automatically update the drive letter, so that the E drive becomes the D drive, and the F drive becomes the E drive. If you choose to install the software on the E drive when you install it, the software will not run because the relevant shortcuts and registry entries will be invalid.

2. A better way is to compress a logic disk with a relatively large free space. You can use disk utilities such as DiskGenius, or you can use the disk management tools that come with Windows. The method is to right-click on My Computer or Computer on the desktop, select 'Manage', click on 'Disk Management' on the left, right-click on the partition you want to compress, select Compress, and enter the size.

If the free space of the disk you want to compress is too small and the space that can be compressed is limited, you can transfer data, delete unimportant files, defragment the disk, and then try to compress again.

This request of yours is completely achievable!! But the premise is SSD+HDD RAID0. In general, the Grub that comes with the Ubuntu system will show you two systems for you to choose, but this is a technical job, and you may not be able to do it yourself, so it is recommended that you remove the SSD and only use the HDD to install the dual system.

Connoisseurs can understand at a glance that laymen need to work hard!! Good luck 2014!!

You can't choose this.,People are all installing 2 systems in a hard disk.,You're equivalent to 2 disks 2 systems.,You can only boot up and press F12 to choose which disk to force boot from.。

I set it in biso. And then as soon as you turn it on, it will ask you to enter the system.

1. There are generally two reasons why the machine cannot install the system under Windows:

A. The partition of the Linux system is inconsistent with the partition of the Windows system, and the common Linux partition is ext2, so if you install the Linux system under Windows, there will be a problem that the partition cannot be found and cannot be installed.

B. Most of the machines released now use SATA hard disks, and some Linux systems do not support this kind of hard disks, so there will be problems that cannot be installed when installing.

2. In order to ensure the stability and safety of the notebook operation, HP officials do not recommend users to install dual systems, and there is no relevant rock wheel information on the operation of dual systems. If you have special needs and must install the Linux system, it is recommended that you try to install a third-party virtual and software for the machine.

3. If you must install Ubuntu's dual system for the machine, I personally recommend that you go to the official website of Ubuntu or the Linux forum to check to see if there is a good way to solve the problems you encounter;

We hope you find the above reply helpful.

Recovery boot is actually very simple, find an installation disk of ubuntu, start from the installation disk, try ubuntu, and open the terminal.

1. Run the command: sudo fdisk -l (here it is not the number 1, it is the letter l), and find the root directory where ubuntu is located.

2. Run the command: sudo mkdir media tmpdir to create a temporary folder, and then enter the command: sudo mount dev sda11 media tmpdir mount system.

3. The next most important step is to enter the command: sudo grub-install --root-directory= media tmpdir dev sda (note, this is sda, do not write sda11 later), if no error report is displayed, it means that it is basically successful.

4. Next, reboot the system. At this point, the guidance was already as usual. But don't go to windows just yet, go to ubuntu first, and type the command in the terminal:

sudo update-grub2 After the grub update is successfully completed, you can reboot into any system.
