Ubuntu on win 7 to delete the partition ,Something went wrong.。。。 20

This one.. System partitions cannot be deleted casually,。。 If you really don't want to see the partition, you can go into PE to change the hard disk ID to 17h to become a hidden partition. Use the HP system disk to restore.

Disk management in Linux is really painful, especially when you are a big child who moves disks, comrade, decisively reinstall.

Well, you deleted the system files

Sad child.

Let's reinstall it.

First of all, you have to solve the conflict problem, you have to pay attention to which disk your ISO is placed in, this disk is not allowed to modify and uninstall! The best way to do this is, 1Allocate empty disks for Ubuntu in Windows in advance; Format or delete, leaving a blank disk.

2.ISO is placed on the C drive or other disks that will not be modified during the installation process (the advantage is that it can be installed normally without uninstalling);

3.After entering livecd, enter sudo umount -l isodevice in the terminal, unmount the disk that you don't need to use, and don't open nautilus, which will mount some partitions.

4.When it comes to disk selection, select the blank partition you started to reserve, and create your own partition. Even if you are prompted to uninstall, as long as you don't open the disk for file operations, you can install it normally!

Problematic hi me!

Try it this way.

First divide your hard disk into a certain space in the win7 system, such as: 100G and delete the 100G partition. Reserved for Linux systems.

Then boot the computer with the Ubuntu CD. Select the 100G partition and install the Linux system.

There can be many reasons why Ubuntu fails to uninstall a partition, and here are a few possible reasons:

1.Partition in use: If the partition you want to unmount is in use, the system cannot unmount the partition. Before you unmount a partition, you need to make sure that the partition is not mounted or in use.

2.The partition has not been unmounted: If the partition is mounted and in use, the partition needs to be unmounted before the partition can be demounted.

3.Partition permission issues: If you don't have enough permissions to unmount the partition, you can't uninstall it. In this case, you need to use the sudo command or log in as root.

4.Partition File System Error: If there is an error in the partition file system, it will cause the partition to fail to be unmounted. In this case, you can use Disk Utility to repair it.

Extended content: Ubuntu is a popular Linux operating system with a wide range of application scenarios. If you want to unmount a partition, you need to make sure that you are doing it correctly, otherwise it may lead to problems such as data loss or system crash.

Before you unmount a partition, you'd better back up your data and make sure you have enough permissions. If you encounter any problems, you can solve the problem by consulting the relevant documentation or seeking the help of a professional.

1. Make a boot USB flash drive: Prepare the ISO image and burn it to the USB flash drive with Unetbootin.

2. Compress a partition under Win7, for example, compress 10G from the D disk (you can set the specifics), don't format it, let it be empty.

3. Start ubuntu from the U disk, click install after entering the desktop Zen (you can also install it directly, but if you have an advanced desktop, you can experience it while installing it, and you can go to the Internet or something).

4、During the installation process, select "coexistence with win7",So that it will choose the partition that has just been vacated,It will not affect win7 (the installation process will be updated if you are networked,A little slow,If you don't connect to the network,It can be installed in about ten minutes)。

After installation,Reboot will enter the grub bootloader,The top option of the Chinese New Year oak is ubuntu,It will start by default,Win7 is located at the bottom,If you want to start,You have to choose。 However, the default launches can be changed.

Ubuntu can access the Win7 partition, but Win7 cannot access the Ubuntu partition (which can be seen in the Disk Management tool). So,You can consider putting ** or something under the partition of win7。

Your win7 should be installed in dev sda1 (you don't know how to do it, just popularize it yourself),You just don't install the system in this partition.。

Because the ubutnu installed by wubi is the bootloader of win,So the partition where the original installation win7 is installed must be retained,And the boot file above cannot be deleted,That's what the first floor said。 In addition, the partition you selected when installing Ubuntu cannot be deleted (of course, this can not be deleted under Ubuntu), because Ubuntu installed by Wubi is just a program equivalent to win, and its file system is also composed of a file that is virtualized under win, which can be seen under win, and it should be. A file in the disk folder is several gigabytes in size.

In either of these two partitions (of course, depending on your situation, it could also be in one partition), either of them will make Ubuntu unable to start. Even total data loss. If you don't know win7 very well, the method of deleting win7 system files is obviously risky, even if you don't delete it by mistake, it will be very troublesome in future maintenance.

When you're only going to install one system, it's best to install Ubuntu directly on the hard drive, and it's not impossible to use the methods provided by the second floor, but I think there's a better way. There's a boot disk creator under Ubuntu.,It's easy to make a liveCD with this.,And I personally think it's better to be compatible or something than to make it with other programs under Win.。

When installing, you only need to choose to start from the USB flash drive, and then you will enter a trial interface, and then click on the installation on the desktop. After that, there will be a partition to select.,If you plan to install only this one system, you can directly choose to use the entire hard disk.。 This way will format the entire hard disk, if you don't want to, you can also choose to keep a part of the win partition, and you can also store the previously backed up data there.

But the partition under win doesn't seem to perform very well when used under ubuntu, and it's slow when copying files. Take your own choosing, if you have somewhere else to back up, or if you don't want anything on your hard drive, I recommend using the entire hard drive.

To add to the previous one, it is safest and most effective to install ubuntu independently:

Use Ultra ISO to write the live CD to the U disk,Select the experience after booting,Enter Ubuntu,Then there is a complete installation on the desktop,Overwrite the win7 partition and it's OK。

It turns out that the things in ubuntu are trying to back it up.,The file system installed with wubi doesn't seem to be the same.,It's better to install it completely.,I've tried it too.。

In this case, the so-called uninstall can only delete the system files of win7 and keep its boot files. The main boot files are the bootmgr file and the boot folder. This can be easily achieved under ubuntu.

It's not recommended to uninstall it like this.,You really want to use only ubuntu.,Or don't install it with wubi.,Re-install it independently.。
