Ubuntu Installation :: Choose OS On Startup Using Grub?
Mar 21, 2011
I've built a system with windows 7 on one hard drive and Ubuntu 10.04 64bit on the other, and would like to choose OS on startup using Grub. I installed each OS with only that drive connected in isolation. I then connected both drives and pointed the bios startup at the Ubuntu drive. sudo os-prober sees the windows 7(loader) and sudo update-grub has given the windows option on startup. However, when i choose windows in Grub I get 'error: no such device' and 'error:invalid signature'. Windows starts ok when the drive is chosen from the BIOS.

I was using the 9.10 version of Ubuntu, and everything was ok. So I decided to update to 10.04, by update manager, and it not works pretty well. So I decided to reinstall my ubuntu. In my PC I also have a instalation of Windows XP, my father and sister uses it. The installation went well, no problems, Lucid Lynx is working fine. But in the grub screen, if you choose Win XP, the CPU starts to whisthle continuously, and the only thing you can do is restart.
I have been reading about it, but do not find the exactly same problem. I have posted a thread in a portuguese forum (im from Brasil) and have no good responses. Sorry about the bad English, I dont have to much experience writing.

I know there must be a way to fix this, but cannot find anywhere how to do it.Problem is when I start up machine, it stops at bootloader asking for language "English" and then "Try Ubuntu without any change to your computer" from screen as if I were running a Live CD or DVD installation.to skip this step so my USB boots normally like a harddrive?

I just installed Ubuntu 11.04 amd64 on my computer alongside my Windows XP partition. However, on startup, my monitor displays "Video Mode Not Supported" which I assume is the Grub2 interface to choose my OS. Unfortunately, it keeps booting into Ubuntu, and I cannot change it. So, through the command line, I made the default OS on startup windows xp. But now I don't know know how to change back... Is there anyway I can change the display settings to be supported by my monitor (it's native resolution is 1440x900)Any help would be appreciated, Been using macs all my life, so I am a noob when it comes to Linux and Windows

Basically I had windows 8.1 running on my fujitsu lifebook A532 laptop and wanted to dual boot kali linux alongside it, however upon installing the linux it deleted EVERYTHING! on my laptop, the grub bootloader only showed kali linux to choose from...
I then decided kali linux is too complicated for me and decided to delete everything and reinstall windows 8 again however I was surprised that my bios screen looks diffrent also I can not edit the boot sequence.
If I press f2 or f12 it takes me to a screen with a tab named Boot menu and its written on it debian and every time I press enter on it it takes me back to this same screen...
I can not boot from cd or usb!

I have a netbook with only Ubuntu (UNR) installed so every time i update my kernel and so on i cannot see/choose the kernel version i want (i believe it enters the most recent one by default). Is there a way to do that without a grub or i have to install it even if i dont have a second OS?

I'm currently running Lucid Lynx, which installed the Grub 2 Boot loader which it currently lists three different Linux kernels. My problem is this:
1. How do I edit the menu to either remove or comment out one or more of the kernels?
2. Can I remove any of the kernels I don't want, which files do I remove, and will doing so compromise my system.

I have a dual-boot setup with Windows 7 and Ubuntu 11.04. Each OS is installed on a separate partition of one hard drive. I read that installing Windows after installing Ubuntu wipes out Grub, so I made sure to install Windows first. Unfortunately, after completing the Ubuntu install and rebooting, I see no sign of the Grub menu. I followed several sets of instructions for reinstalling Grub, and after running grub-update, it appears that Windows 7 was added to Grub, and after examining the grub.cfg file, it appeared that that was the case. Despite appearing to be installed perfectly once inside Ubuntu, Grub doesn't show anything at startup. No matter what I try, I can't seem to make Grub appear, and now I can't get back to Windows 7. Am I missing something, or should I try a different bootloader?

I've been using Ubuntu for 6 years now as my major OS, dual booting with Windows. (just in case...)
I am now ready to completely abandon Windows as all the music editing and video creation tools I could not live without are available in Ubuntu and working great!
QUESTION: If I format the C: Windows partition, will I still have the GRUB to choose Ubuntu from? (I'd like to get rid of GRUB altogether to speed up my boot time)

I am running ubuntu 10.4, windows 7, and I had ubuntu 10.10 on a single hard drive. I upgrade the 10.10 system to 11.4 and now my grub menu which is on the 10.4 system shows two windows and two 11.4 installations.
How can I clean this up? Also I have tried to start with the grub 1.99 on the 11.4 system and all I get is a black screen at startup. I am happy with grub on 10.4 except for the extra lines.

I use Ubuntu on his edition 8.10 and have always been very pleased, until 11:04 last version. Actually used a dual boot for constant use of certain programs that only work on windows. By installing the latest version, everything is as before except that I can not see the initial grub, show me out of range. My boot loader resolution is 640x480 and still I can not see the grub at startup.

KPackageKit sometimes tell me there are packages to upgrade, and some are tagged as bugfixes, and some as security upgrades. Are there any ways to find out from the command line which packages are which? I'd like to only apply a certain class, automatic, without using KPackageKit. Using 'apt-get upgrade' I get a list of upgradeable packages, but no list of which class they are. Is there a way?

I recently upgraded to the newest version of Ubuntu. I dual boot with Windows 7.
All was going fine the first few times I used my system after the upgrade but I have now run into a serious problem. I'm not that technical so will explain this as best i can.
Basically, when I switch my computer on, I can not get to the screen that allows me to choose an operating system. Before it gets there it just restarts.
I guess its a problem with the GNU GRUB software. It just seems like the computer can't find it and restarts itself. So I can't get into either Ubuntu or Windows at the moment.

The thing is that whenever I try to install Ubuntu (Xubuntu actually, but the problem seems to happen with any desktop environment) I fill the spaces, choose the partition where to install, set the mount points and everything, but when I get to choose the keyboard layout the installation freezes, it just stays there and it won't give me the chance to submit a username and a password for my Linux session.

drive is as follows:
NTFS Partition (Storage)
NTFS Partition (Win7)
Ubuntu
I am trying to put GRUB2 on the Ubuntu partition, but it will only let me pick the first two. If I pick the Ubuntu partition in the last dialog bix, it is listed as /dev/sda-1 I also have no idea why is says "-1", because the first two are fine at 1 and 2 respectively.

With the startup disk creator on Ubuntu (Currently running Ubuntu 10.04 LTS) I realised you could boot Ubuntu from a USB and then install it onto the HDD if you wish to. *Side note* Still amazes me you can run a whole operating system from a USB memory stick drive *End Side note* Now My question is: 'Is it possible to have multiple distros of Linux on a USB memory stick and choose which one you wish to boot from when you boot up the computer?'I was hoping to get a seagate portable HDD ((here) and load quite a few different Linux distros on it to get a broader view of Linux than just Ubuntu (Although Ubuntu does rock ).
Is there simple ways of doing this? I have read around this forum and Google and a suggestion was given to install all of the distros onto the portable HDD/ USB memory stick and then install Ubuntu onto it last as its good for picking up other OSes in its GRUB. (Again if my idea on GRUB and its workings are wrong please point it out - got to keep learning)

i decided to build a home server on an AMD64 (buyed some years ago) for file storage, printer sharing and something else... I've searched a lot for "the best distros for server" and discarding extreme solution (like command line only) what remains is: Ubuntu, Fedora and Debian
Now the problem: how to install more than one distros on the same hdd? what i know is that i need a bootloader (grub/lilo) and partitions for boot,swap, and remaining space will be split for the distro itself.
I think is a good idea to have a partition only for files (/data) that all distros can access, but for sure i'd like to have one /root and one /home partitions each distro!
I can't understand if the correct way is first of all to install a distro (let's say ubuntu), then set up everything such as partitions and bootloader and then install other distros. I'd like to know if it is possible to manage dinamycally the space reserved for distros, so i'll be able to install 2,3,4,5...distros with no problems.

I need to upgrade a machine to F10 (64-bit), and I need to make a decision on whether to start using LVM or stick with the classical partitioning mode. I have used RedHat/Fedora for quite some time, and always used the standard partitions. Fedora documentation says that LVM (Logical Volume Management) partitions provide a number of advantages over standard partitions. Also, numerous contributors on these forums seem to favor LVMs. In order to make an educated decision I need answers to some questions:
1. What are these advantages that Fedora documentation refers to?
2. Is it easier to work with LVMs than with classic partitions?
3. For those of you who have experienced working with LVM partitions, what were the advantages/disadvantages to working with LVM partitions?

Just migrating to linux but I don't want to give up linux just yet so I've stuck in a 2nd hard drive to install linux on which I've done, now I have windows on one hard drive and linux on the other but my computer boots straight onto linux. I need the option to choose which os to boot into on startup which I've heard GRUB is the best option but I have no idea how to go about setting this up.

Some thing quite bad happened to me , i installed debian jessie about 2 month ago. Today I wanted to try what a gnu/linux is like so I installed dragora 2.2 on one of my free partitions , (sda 1 is my debian root , sda2 is my debian home, I had sda4 which nothing was on it so i installed dragora on it. But something bad happened , during boot time you get this page which asks you what distro you want to enter in past I had just one choice and it was debian jessie, I expected after installing dragora I will see 2 distros on this page, but i get just 1 , and that's dragora ... but maybe i should mention this that when entering dragora i can access all my previous files , debian systemfile , debian home , they are still there but i can't enter debian jessie ...

I have a drive... let's say SDA1 On that drive I do a F10 install.
Now I remove the drive and put another drive in and did F11 install on another drive in the SDA1 slot.
Now I put the other first drive in.
Now, F10 is on SDA1 and F11 is on SDB1.
What can I add to FSTAB and GRUB.CONF so I can choose which drive I want to use at boot time?
