comment Can I move the contents of the boot partition to the root drive?
Easier yet, do sudo apt-get autoremove. That will usually remove all but two or three kernels.

comment Xubuntu 15.04 fails to boot into a live session from a live USB, but only when my SSD is plugged in
More details, please: You say "it always fails to boot," but that's imprecise. What happens when you try? Do you see any error messages? Does it boot the wrong thing? How are you attempting to boot the external medium? (Via the firmware's built-in boot manager? If so, what option are you picking and what other options are available?)

comment Could not access an NTFS drive after making it auto-mount, Ubuntu 14.04 (Win7 not installed)
Unless the NTFS drive is an external device that you exchange with a Windows system, using NTFS on a Linux-only computer is a Bad Idea. Linux has no NTFS repair utility. (The ntfsfix tool basically just flags the disk for checking under Windows.) It could be this is the source of your problem, but whatever the case, once you fix the problem you should back up, switch to a Linux-native filesystem, and restore. (Assuming the disk is not being shared with Windows.)

comment Can't install Ubuntu on my Laptop already running windows 8.1
You should NOT disable EFI-mode booting. Disabling Secure Boot is separate from that, and is usually not required, either. See my page on EFI-mode Linux installs for more of my advice on this subject. If you continue to have problems, post a new question that specifies what's not working.

comment I keep getting the same GRUB error?
If the only problem is that error message, ignore it. GRUB sometimes displays errors but works normally otherwise. If you're having a problem beyond that error message, please say what it is.

comment Resize ext4 Partition to >2TB without data loss
Have you truncated your fdisk output? It currently shows no partitions. If you have existing partitions and if your disk currently uses the MBR partition table, you can convert it from MBR to GPT using gdisk -- see rodsbooks.com/gdisk/mbr2gpt.html for details. As psusi says, you may need to change boot modes or re-install your boot loader. As to future expansion, that's possible, but you may need to move the backup partition data if you add space to your RAID. IIRC, parted does that semi-automatically. gdisk does it via an explicit command.

comment Portable installed ubuntu on a Pendrive that boots on UEFI and BIOS
This might work, but it's conceivable that the BIOS and EFI versions of GRUB will interfere with each other. I therefore recommend installing some other EFI boot loader for Linux instead of GRUB. My own rEFInd is likely to be easy to install and configure. To do this, you would not do the apt-get install grub-efi-{arch} step, but would install the boot program of your choice manually, to EFI/boot/boot{arch}.efi on the ESP.

comment Can't boot Lenovo laptop (v570) after installing Ubuntu
You could also see if you can boot an Ubuntu live medium (like your installation disk) and run Boot Info Script (in the boot-info-script package, IIRC). This should produce a file called RESULTS.txt. Post it to a pastebin site and post the URL to your document here. If this procedure works, it will give us more information about your configuration, which might provide clues or suggest solutions. It might not work, though; if your firmware is badly hosed, the Ubuntu medium won't boot.

comment How to install Ubuntu on Lenovo idealpad flex 10?
wbad, I'm afraid that 32-bit UEFI support in Ubuntu (as in most Linuxes) is pretty much non-existent. Installing on such a system can be done, but only by playing on "the bleeding edge." I know of no simple step-by-step procedure on the Internet to help with that. If you're uncomfortable with that, my best advice is to return the device to the store for a refund and get something with a 64-bit EFI instead.

comment Ubuntu partitioning advice
I wouldn't say the critical factor in this case is not what's more important, but rather what requires more space. This example's /dev/vda3 is much bigger than the other partitions -- 109GiB vs. 7GiB for /dev/sda2. If /var will hold lots of data, then by all means, use /dev/vda3 for it; but if /home will hold more data, mount /dev/vda3 there. Incidentally, 7GiB is pretty small for an Ubuntu installation. It may be adequate, but personally, I think I'd start over and give two or three times that much space to Ubuntu.

comment Partitions that can't be read
Also, please clarify what you mean when you write that you "can't read 2 partitions." Do you mean you can't mount them, you get errors when you try to access them via dd, they don't show up in GParted, or something else? The output of sudo blkid may also be helpful.

comment Help me Get to the Ubuntu 15.04 Partition, please
You say you "get a black screen with lots of white (& some green) text and it refuses to move into the GUI." Post that text! It almost certainly provides the clues needed to fix your problem. If necessary, take a digital photo of the screen when it stops working and post a link to that digital photo.

comment Laptop boots directly to Windows, Ubuntu alredy installed and refind not working
This is basically the alternative naming option described in the rEFInd documentation. Unfortunately, some EFIs are buggy and don't remember their boot options.

comment Can't resize partiton on Lexar USB drive
Why you posted the fdisk output is irrelevant to my point: You posted the output of the wrong fdisk command. If your fundamental problem is with GParted, you should post a screen shot of its main page and describe its problem in detail. Most such "grayed-out resize option" problems in GParted are caused by partitions that are in use. The solution is to unmount them (if they're filesystems) or disable swap (if they're swap). Sometimes unmounting a partition requires booting from a live USB/CD rather than from your regular installation.

comment trying to re-install Ubuntu from USB, initramfs error
In that case, my hunch is that you're actually booting from the hard disk, and it's failing because you deleted a partition with critical files. The keystroke you use to access the firmware's built-in boot manager varies from one machine to another; sometimes it's F10 or F12, as you note in your post; but other times it's Esc, F8, or some other key. Check your manual, watch for prompts as you start the computer (you must be eagle-eyed; they generally stay on screen for only a second or two), or try every function key, Esc, and Enter.

comment What does it mean for two partitions to be adjacent?
Also, note that doing as the_Seppi suggests will result in the loss of all data on /dev/hda3 -- after all, it's been deleted before /dev/hda1 is expanded. If you truly want to merge two partitions (which to my mind implies preserving the data on both), you must copy the data from one to the other before deleting the one and expanding the other. As a side note, many people talk about "unallocated partitions," but that's an oxymoron -- a partition is, by definition, allocated space. Unallocated space is, also by definition, not partitioned.

comment Unable to resize lvm2 partition
Follow solsTiCe's link and advice. Also, your computer is booting in EFI/UEFI mode. After you've resized your LVM, you must install Windows in the same mode, as described here (among other places). You may then need to use the firmware's built-in boot manager to reboot to Ubuntu and then run sudo update-grub to get GRUB to recognize Windows.
