GParted

Very handy live distro for modifying disks and partitions. My only complaint about parted/GParted (not specifically this live distro) is that it doesn't/can't manage LVM volumes. But the live distro does include the required LVM (commandline) tools pre-installed, so it's easy enough to also manage LVM. It would be nice though if there were some GUI LVM tool somewhat like GParted.

I used Rufus 3.9 to create a bootable USB. It boots but when I try to do anything (select the first option in the menu) I keep getting ACHI host controller unavailable. According to device manager there are two ACHI storage controllers! The bios is UEFI. Maybe the hardware is too new. I built the machine in January: I9700 CPU on ASRock Extreme4 MB, a Sabrent NVME SSD connected on the MB and a hynix 2.5" SATA SSD. Video and sound are on MB. Machine works great and is multiple times faster than the one that I built 7 years ago and which was near state of the art then and still working fine as my #2 machine. It hangs on the no ACHI message. First time I had to turn off and on to reboot; next time I used ctrl-alt-del to reboot.

Actually this is NOT Gparted itself, but an ISO image for an extremely poor and antique Linux distribution, that has many problems. Notably this ISO is not secure bootable, does not support many hardware devices on the motherboard (e.g. wifi, graphics drivers needed to boot and render the needed X11 environment, missing microcode updates for modern CPUs or GPUs, required by the kernel provided that will block some common ranges AMD and Intel processors without the microcodes!). Gparted itself is an excellent product but separately from this Linux distrib. Instead of using this, download a modern ISO distrib built after mid-2019 (so that they support the microcode updates from Intel and AMD after the Spectre/Meltdown issue), and a Linux kernel version 4 at least. Then use the "RUFUS" freeware to create a bootable USB from this ISO (note: RUFUS includes a builtin support to download and install Linux on your USB key) Once you have booted Linux on the USB (you may eventually need to disable Secure boot in your UEFI BIOS settings if your BIOS does not recognize the UEFI bootloader on the USB), Gparted is generally included in the live distrib (you don't need to install Linux on your PC, Linux runs in a RAMdisk), but if need you can use "sudo apt install gparted" (it will install it in the live ramdisk, not on any disk of your PC). First make a stability test in this live distrib: open Firefox, visit a media-heavy website like Youtube (launch a video, it should be smooth without lags), or try playing a video that you have added onto your USB key or a DVD, or open a command to launch a "Prime test" or similar benchmark/test tools: your PC should not hang or crash. Only when you've done this test to make sure the Linux Live distrib is stable, you can launch Gparted from this Linux live that will allow you to edit/copy/backup/move/resize your partitions. So DON'T use this poor Linux distrib: it does NOT work reliably on many PCs, and an antique Linux distrib and missing drivers can be very dangerous for your data, your disk partitions may finally be definitely corrupted if Gparted crashes in the middle. Note: before copying or moving a partition with Gparted, start first by reducing its size to the minimum (which depends on the volume of data stored in the filesystem), and apply. It will then save you a lot of time when moving/copying partitions. For non-filesystem partitions, resizing is not proposed, you can only copy/move them as is. Note finally that you should have a Windows recovery USB key in some cases, in order to be able to : - or use "DISKPART" or "MOUNTVOL" to mount the partitions you want to setup for your windows boot: mounting allow inspecting what is in each partition and it facilitates the use of BCDEDIT - launch "BCDEDIT" and fix the boot order or change the drive letters in the BCD information. Make sure you have understood how BCDEDIT works (BCDEDIT on Windows allows you to manage the boot entries, but its syntax is quite complex. It is however frequently needed when your PC no logner works or if the Windows recovery environment "repair this PC" is unable to correctly detect the correct UEFI system FAT32 partition (ESP), which should be the only one marked ACTIVE on ALL your disk drives, or the correct NTFS partition containing the windows recovery tools, or the correct NTFS partition containing the Windows installation C: and the hypernation file for resume.). If you have a problem with resuming Windows, deleting the hybernation file is possible in Linux: Windows on the next boot wsill recreate it as needed (unless Windows has been setup to remove the hibernation). On modern PCs with SSD and "Fastboot" suppport in your UEFI bios, you don't need hibernation, as Windows can make a full boot in a few seconds, faster than from hibernation (notably on PCs with lot of RAM: loading a giant hibernation file of several gigabytes, is much longer than a plain boot), so disable it in Windows with "POWERCFG" from an administrator CMD window (it will save several gigabytes on your SSD!) Beaside that, "Gparted" is excellent but ONLY on a decent Linux distrib, but NOT in this one.

Great product, have used it for years. It works well on all drives and usb drives.
