I've got an HP Pavilion Touchsmart notebook that came with Windows 8. I've upgraded to 8.1, and now I want to dual-boot an Ubuntu distribution with Windows 10. When dual-booting with Windows 8.1, the Windows Boot Manager always took priority, even after installing GRUB. What do I need to do to get GRUB to be the default bootloader instead of Windows Boot Manager?

After changing a few lines in xorg.conf, I can no longer boot Ubuntu (I assume it breaks when trying to load up X), so I need a way to boot into a single-user mode. However, there seems to be zero guides on the Internet how to do it, because they all assume I can actually edit files on my computer, and I obviously can't.
So how do I load Ubuntu in single-user mode?
When I turned off splash, I figured out the problem: whenever Ubuntu can't load X server due to some error, it switches to tty1 and waits for the prompt, but doesn't turn off the splash.

Is there a way to easily turn on/off showing the boot messages (loading the services) when Ubuntu starts? Is it something in Grub2?
I am running Lucid.

I have seen many videos that make Ubuntu faster, but only makes the desktop faster.
I am looking to make my computer boot faster. Is their anything i can do to make Ubuntu boot significantly faster?

When booting to the graphical desktop fails we sometimes are recommended to boot into a "root shell" or to boot in "recovery mode".
How do I do that?

I've installed the following version of ubuntu om my machine.
ubuntu-12.04-desktop-i386.iso
But when I switch on the computer, I get command line.
Ubuntu 12.04 LTS COMP-1245 tty1
Once I provide my username and password, it authenticates login and then displays a link to documentation.
Now, how can I start GUI? I'm stuck at command line?

I downloaded Ubuntu 14.04 (64 bit) lts. I made a bootable usb stick. But I keep receiving this error message upon booting:
SYSLINUX 4.04 EDD 20110518 Copyright (C) 1994-2011 H. Peter Anvin et al

After upgrading my laptop from karmic to lucid, my fat32 partition won't mount automatically. I get the message:
The disk drive for /osshare is not ready yet or not present
Continue to wait; or Press S to skip mounting or M for manual recovery
Funny thing is, if I skip, then /osshare/
is mounted once I log in.
I've a similar setup on my desktop, and it works fine. Fstab on desktop:
UUID=4663-6853 /osshare vfat utf8,umask=007,gid=46 0 1
/etc/fstab
on laptop:
UUID=1234-5678 /osshare vfat utf8,auto,rw,user 0 0

I have the ISO image file (that is, *.iso
) and I am trying to boot my VirtualBox installation with this image. Is it possible? I know how to mount my ISO image to my filesystem (on my host machine), but I don't think VirtualBox boots an OS from a location on my file system.
I've even tried to mimic mounting, such that VirtualBox thinks it has to boot from the CD drive, but this failed.
What is the correct way to boot an OS from an ISO image in VirtualBox?
My host machine is Ubuntu 10.04 (Lucid Lynx) and my VirtualBox version is 4.1.4.

Is it possible to disable X at boot time? I'm setting up a server so it would be nice if it wouldn't load the graphical interface every time I boot.

My /boot partition is nearly full and I get a warning every time I reboot my system. I already deleted old kernel packages (linux-headers...), actually I did that to install a newer kernel version that came with the automatic updates. After installing that new version, the partition is nearly full again. So what else can I delete? Are there some other files associated to the old kernel images?
Here is a list of files that are on my /boot partition:

This issue came up recently for me (and I've been prompted to lodge it as a specific question about it):
My system is not dual-boot, I run a standard Ubuntu desktop system "on the metal" (I think running it in a VM is the same).
Pressing c while booting does not cause the GRUB menu to appear (which I believe it does for a dual-boot system).
How can I get the GRUB-menu to present itself on a single-boot system?
