When I installed Linux, I was left no choice but to use the installer's auto-partitioning that would create a partition for the operating system. Since I've ran this installer so many times for troubleshooting purposes, I understand that normally it should give you the ability to resize your partition with a little draggy arrow, but on this occasion, I guess it didn't feel like it, so I had to make a 931.04 GiB partition for Ubuntu called /dev/sdb5, a 'lvm2 pv' file system located under the tree of the extended file system, /dev/sdb2. My issue here is that I have better things to do with 900 GiB of hard drive space, so I would like to reduce a 931.04 GiB partition down to about 33.0 GiB. Normally, with Windows, I would open Disk Management and click Shrink Volume and it would work because Windows, with all of it's faults, knows the benefits of putting everything in NTFS on one partition. Allow me to go through some suggested steps: - I am currently running a Live CD of Ubuntu (KDE, to be precise) and I have GParted installed - There are 3 partitions on the hard drive: /dev/sdb1, which is a 487.00 MiB partition that only uses up 78.01 MiB, and the two other partitions mentioned earlier - There is a lock symbol next to /dev/sdb2 and /dev/sdb5 - I highly doubt that a fresh installation of Kubuntu can take up 931.04 GiB, yet it says that sdb5 has 0.00 B of unused - When I right click on sdb1, It says I can delete, resize/move, copy, format to, manage flags, check, label file system, new uuid, and information, though I don't see any of this solves my problem - When I right click on sdb2, it only says manage flags, and information. Again, not pertinent - When I right click on sdb5, It says I can resize/move, deactivate, manage flags, and information, yet when I open resize/move, I can only change the alignment. Deactivate appears to remove the locks, but the minimum size for sdb5 is still 931 GiB. I should also mention that sdb5 has an 'lvm' flag (No, I don't know what this means) How do I shrink /dev/sdb?

are there any quick commands for this? I might get some software to help me.

Well, if I'm gonna format the hard drive, actually, I could just get rid of the redundant partitions now that I think about it.

S***, someone's gonna have to reinstall Total War: Rome II tomorrow...

My GPU is a GTX 1060 EVGA SC. Kubuntu probably wants to use OpenGL if anything but I don't think that's pertinent. As for GRUB, I don't even know what GRUB is. All I know is that if I disable the hard drive, GRUB will make an error message, but nothing will work. Could you clarify on what I need to do, should I reinstall Kubuntu, or Windows, and does GPT / MBR matter? Should I swap Kubuntu for something without GRUB?

Specs: i5-6500 GA-H170N-WIFI 16 GiB of 2,133 MHz DDR4 Dual Channel Windows is on an Intel 120gb SSD I installed Kubuntu into a separate partition on a 5400rpm TiB hard drive Windows 10 Home x86-64 w/ Anniversary Update very minimal experience with Linux Okay, so I was trying to install Kubuntu as a dual boot separate partition on my auxiliary hard drive so I created a partition for it manually through disk management and it looked good with 30 GiB, so I got a ISO to USB conversion of Kubuntu plugged in and booted and the installer was working fine, but I think I chose something wrong because whenever I boot my computer, no matter how I press DEL or F12, it will NOT boot Windows, it always shows Ubuntu startup or grub fail. I can prove that it didn't delete Windows because I can use Kubuntu's file manager to go back on my Solid State Drive where Windows was installed and all of my files are still there. I was forced to Kubuntu's auto-partition that wouldn't let me use my new partition, it created it's own, so now my hard drive has like 4 different partitions. One thing I noticed while constantly hitting f12 and CTRL+ALT+DEL over and over again was that no matter where I booted, grub would show up, which means that Ubuntu is almost like part of the UEFI or something. One, how do I get back into windows, two, how do I delete Kubuntu off my machine, and three, why does Kubuntu run at 19Hz and stutter and buffer in constantly? Is it the video drivers? No, I didn't make a backup / recovery / repair disk. Would reinstalling windows do anything? I have the Windows 10 ISO How do I do what I need to do?
