У меня есть диск с разделом ext4 и кучей неразмеченного места. Каким образом можно на Windows 10 сделать extend этого раздела? Записать GParted live cd не вариант т.к. у меня нет флешки под рукой.

Using a partition manager to resize a Linux partition is not as simple as it may sound. To resize a partition in Windows, you can either use a third-party partition manager or use the built-in Windows Disk Management. This allows you to make the most of the available disk space and optimize the performance of your system. You can also use resizing tools that work in Linux to safely resize your Linux partition.
First, open the Disk Management window. In the ‘Partition’ tab, click on ‘Resize/Move’. In the resulting window, click on a partition and drag it to the right side. You can change the size of a partition by entering the correct number. Once you have made the desired adjustment, click the “Start” button to perform the process. Note that you do not need to delete any data from the partition when resizing it.
Removing the Windows partition will have no effect on booting Windows. Windows will report an error at boot-up if the disk size does not match the records. Once this check is finished, reboot your PC. Using a Linux partition manager, you can resize partitions without affecting Windows boot-up. You can also use the tool CHKDSK to check your disk health. This will allow you to check if there are any errors or other problems.
Can I Extend Ubuntu Partition From Windows?
If you need to increase the size of your Ubuntu partition, you can extend it by booting to Windows. You can use Windows’ Partition Manager to extend the size of your partition. Windows partitions are typically twenty to thirty GB in size. To increase the size of your Ubuntu partition, you need to free up additional disk space. Fortunately, this process is easy, even for beginners. Here are some tips for partitioning your Windows partition.
First, connect your virtual disk to another VM. This will be your source VM and your helper VM. Windows 7 and XP have different methods for extending partitions. Windows XP’s native tools do not allow you to extend partitions in Ubuntu. Windows 7’s tools do the job just fine. Once you have installed your virtual disk, run the partition manager and select Extend Volume.
Can I Increase Linux Partition Size?
How can you increase the size of a Linux partition from Windows? There are a few options. The first option is to edit the partition size in Windows. To do this, you should be logged in as an administrator. Click “Create and format hard disk partitions” and then choose a specific amount for the new partition. Then click “OK” and reboot. The partition should now be larger than its current size.
If you’d like to increase the size of an existing partition, you can use the partition resize/move feature. This will expand the partition size by half. This method will leave you with a partition that has a free space of at least 8 MiB. However, you should note that free space cannot be used for data storage. If you’d prefer to use the partition as it is, you can also shrink the existing partition to free up space.
Alternatively, you can also use the GParted tool to change the size of a partition. GParted is an excellent universal tool for changing the size of a disk partition. Once you’ve identified which partition is MBR and which one is GPT, you can use the partition extender utility to change its size. Once you’ve made the changes, you can check out the free space in Disk Management and Windows Explorer.
How Do I Change Partition Size in Linux?
If you’re wondering how to change partition size in Linux, you’ve come to the right place. First, you need to unmount your disk in order to resize it. In Linux, this is impossible unless you unmount the root device. This can be done using the command hcl detach diskname, where diskname is the name of the disk, for example, /dev/sdb1. To change the size of your partition, type the i partition-number command and then press Enter to execute it.
In addition to the command line, there are several utilities in Linux that allow you to resize disk partitions. For example, fdisk is available on all Linux distributions. It allows you to resize a single partition or multiple partitions. If you need more space, simply specify the size in Gigabytes, Megabytes, or Wise bytes. When using this program, you must make sure that your partition table is GPT or msdos.
Can I resize an EXT4 partition from Windows? Yes, you can! The file system Ext4 was released in April 2009 and is the successor of EXT3. It is an efficient way to manage disk space and defragment disks. Resizing a disk partition is a simple and effective way to optimize hard drive performance. To perform this operation, you must first format the partition in Windows.
Fortunately, there are some built-in tools available to resize partitions. One tool is resize2fs, which was originally designed for Linux systems and has been ported to Windows. To use this tool on Windows, however, you will have to perform a command-line procedure. To use resize2fs, you must have root permissions on the disk.
You cannot create an EXT4 partition in Windows using the Disk Management or Diskpart command. This is because Linux and Windows use different file systems. While Linux supports the NTFS system, Windows isn’t capable of reading the Ext4 file system. That means that you must use third-party software to create an Ext4 partition on Windows. Therefore, Windows cannot create an EXT4 partition with these methods.
How Resize C Drive in Ubuntu?
In Ubuntu, you can resize the C drive by right-clicking it and selecting “resize/move volume.” Then, drag the right border towards the left. This will make a new partition on the C drive and you can combine it with the D drive. Note that you need to set a password. Then, wait for the resizing process to complete. Once the resizing process is complete, you can delete the existing partitions.
If you’re using a Linux operating system, Gparted is the application you need. Once you have installed this application, open a terminal window and follow the installation instructions. Alternatively, you can install Gparted from the Ubuntu primary software repository. It’s part of the “Debian Main” repository, and you’ll need to install apt-get to install it. Make sure you choose the correct installation method, as the installers are not as intuitive.
How Do I Get More Space on Linux?
In Linux, you can manually clear the /tmp directory, but this is not recommended. Your main interest should be the /var directory, which contains files such as ‘/var/log’, ‘/var/cache’, and incremental backups. The latter can take up the entire disk, so deleting this can free up space. To defragment the disk, you need to have root privileges.
You can also use the rmLint tool to scan multiple directories for duplicate files, non-stripped binaries, and broken symbolic links. The program will then generate shell scripts and executable output. This tool automatically removes those files. Once you have used it, you can reboot to enjoy more space on your system. You can then install a virtual disk if you need more space.
The ls command shows the size of each file in a directory, as well as the total amount of space that they take up. This command is also helpful in identifying which directories are taking up most space. You can further narrow down the directory that’s taking up most space by repeatedly typing ‘du’. After doing this, you’ll have a clearer picture of which files and folders are consuming the most space on your disk.
How Do I Make My Ubuntu Partition Bigger?
If you want to increase the size of your Ubuntu partition, you must follow these steps. To do this, you must use a USB drive or live CD. Once you have the live CD, run the partition editor GParted. It is a compact graphical partition editor. The program also acts as a front-end to Linux’s terminal commands. Once you have the partition editor, you must choose a file system to expand or decrease the size of.
You can resize the partition size using Gparted. First, load the partition on the hard drive and click on the right-click menu. Next, check the box labelled “apply changes”.
