Ubuntu Installation :: Boot Sequence With Dual Boot And Two Drives?
Dec 10, 2010
recently sent up another computer as follows:Two sata drives. Windows 7 was installed on the first drive(sda)and booted successfully. This drive was disconnected ( I have had some installs where Unbuntu wipes out the existing C drive eventhough I am installing to D) and Ubuntu was installed to the second drive (sdb). At one point I had to rebuild the grup on the Ubuntu drive and was careful to make it installed on the Ubuntu drive. To my surprise when the PC booted up I saw the Grub menu with a menu entry for Windows. The Windows drive was always the primary drive before the Ubuntu install. I was planning on the Windows drive being the boot drive and using a boot manager to determine where to go from there. If I utilize the BIOS boot option (F12) I can boot each drive individually. I cannot in BIOS set a particular drive to boot - just a hard drive. Everything is working I am just curious why the primary drive does not boot first. IN BIOS the Windows drive is a primary SATA with a lower number that the Ubuntu drive which is listed as a secondary drive.

I can only use the Live CD to operate Ubuntu. After typing in the command sudo fdisk -l, I get the following?
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[Code]....
And when I boot without the Live CD, I get the following message in the GNU GRUB Version 1.98-1ubuntu7 window page.

this may be a very stupid question, but. My computer has two hard drives. One has Windows XP installed on it. The other is blank.
Is it possible for me to install Ubuntu onto the second hard drive, and run a dual-boot using GRUB during startup? Or does it only work when both OSs are on the same hard drive?

I would like to install Ubuntu 10.04 on my new 1 TB hard drive. I currently have Windows XP installed on a 160 GB hard drive for things that I cannot do on Ubuntu. I would like to know if it's possible to install the other hard drive, and then dual boot Windows with it? Effectively dual booting across two hard drives. I wouldn't care if GRUB replaces the standard Windows bootloader, just as long as I can choose between the two at startup

I have Ubuntu 11.04 on 1TB HDD and Win 7 on another 1TB HDD. Right now I have to unplug a SATA cable to get to boot into one or the other. What is the best way to be able to pick. I don't care which OS I do it in or which is the primary, if there has to be one. I have an MSI mobo.

I've been using ubuntu exclusively on my two laptops lately, for coding and all of my other work. I plan on installing it onto my desktop now for work as well, but I would like to retain Windows 7 so I don't have to worry about compatibility for all of the games I love to play. My question is this:When setting up my partitions, how much space (and what format) should I set aside for windows to write and read games from? I have a 500GB hard drive currently, and was planning the partitions as:
1. Windows 7 (NTFS, setup with Windows installer) ~20 GB
2. File Storage (NTFS, set up with the Ubuntu install partitioner) ~452 GB
3. Ubuntu (EXT3, set up with Ubuntu install partitioner) ~ 20 GB
4. Swap (~2x the size of my RAM) ~ 8GB
The plan is to have Windows install and execute games from the NTFS File Storage partition, while being able to access the same partition from Ubuntu for my documents, code files, music, etc.I don't know if this would work, and I'm also not sure what my file system will be like (windows or linux-y?) if it did. Will this work? Or is there a more elegant solution?

I have recently built a new system which has two internal sata drives. The plan was to install windows 7 one drive and ubuntu 10.10 on the second drive for KVM hosts. I started with the windows install which completed, then I went forward and installed ubuntu 10.10 64bit to my second drive (sdb). During the installation I chose to manually partition my drive. i partitoned the drive (sdb) as follows
/boot - 1gb
/ 40gb
swap 16gb
extended partion of 400gb
I then selected sdb to hold the boot record, as it was set by default to sda (my windows drive). The OS installed fine. I then went to reboot my system so go back into windows, by selecting the first drive in the bios. Once selected the system keeps booting into Ubuntu, no matter which drive I select. Now I checked the grub.cfg file and i see all references to hd1 there is no reference for windows found. I then proceeded to do 'sudo update grub2' this did not pickup any reference to my windows droive to add to the grub menu. When i select the ubuntu drive to boot fom my bios, i get no grub menu appaer it just boots quite happily into ubuntu. Can anyone please provide any resoloution to this, I can provide additonal outputs regarding my partion tables etc. later this evening when I get back from work.

Is it possible to create a dual boot system from two separate disk drives each having been created as a single boot computer? I have an 80gb disk drive with Windows XP installed on it. I have a 160gb disk drive with Ubuntu 11 installed on it.
I have installed the Windows disk drive as drive 0 and the Ubuntu disk drive as drive 1 in my computer. Each disk drive was set with cable select pin settings. The computer boots to windows. If at all possible, how would I go about setting up the system to dual boot to both windows and Ubuntu? I have attached screen shots of part -l, gparted 80gb disk and gparted 160gb disk.

I have the following PC set up:
Dell 8400 with 3 GB of RAM with 3 160 GB SATA drives:
The first one has Windows XP installed on it.
The second one has been newly formatted and Ubuntu 10.04 has just been installed on it (20 GB / and 6 GB swap) with grub being installed on the first partition and not the master boot record. The remainder will be for storage for Windows.
The third drive is simply storage for Windows.
At this point I am able to boot XP just fine, but I'm not able to boot Linux. I just getting a blinking cursor or the PC just reboots when I choose Linux. I believe I have set up my boot.ini properly using:
C:Bootsectc.lnx="Linux Ubuntu"
After running dd if=/dev/sdc1 of=bootsect.lnx bs=512 count=1 and putting that file in place.
For reference, I don't believe this is a Linux problem, as much as I am simply trying to guide the ntldr to be properly pointed to a place where it can boot Linux. When I go into the bios and disable the first and the third hard drives, grub pops right up and I'm able to boot Linux with no problem, so that piece is fine. I think it's just now trying to get the correct syntax so I can boot Linux without having to disable drives and reenable them.
For kicks I even tried these syntax types in boot.ini:
multi(0)disk(0)rdisk(1)partition(1)="Linux11"
(i.e. 2nd disk, 1st partition ...etc...)
I read many troubleshooting documents on dual booting and so forth but I just can't get this right. For reference, I stated the way XP views my Hard Drives in the intro, which seem to be a different order than Linux sees them, yet I believe I've tried all the combos of settings for this to work (yet clearly have not). I have attached the output of boot_info_script*.sh here: [URL]. Boot Info Script 0.55 dated February 15th, 2010 ..... Devices which don't seem to have a corresponding hard drive.

I'm a n00b at dual booting and I plan on installing Ubuntu 10.04 on a separate hard drive than my Windows 7 64 bit one in a dual boot situation. I have read that you can do this by unplugging the Windows hard drive, install Ubuntu on the other one, and than plug the Windows hard drive back in and everything will be fine and dandy. Is this correct? If it is, will I have to manually set the Primary and Secondary drive (in the BIOS I think?), or will it automatically do that.

I've been trying to properly install grub for the past 3 days and failing every time.I recently bought a new computer and would like to dual boot Windows 7 64 and Natty. On my previous machines, ubuntu installer has automatically detected windows. It does not do so on this machine.I have three hard drives: 2 ssd's and a single 3 tb drive for storage.
I would like one ssd for windows 7 and one for natty.Currently, I am able to boot into both OS's but only by altering the boot sequence of the drives from the bios. I am hesitant to install grub to the windows drive for fear I will lose the ability to boot into windows. I did this early in the discovery process and ended up having to reinstall windows.

I need a suggestion on setting up a dual boot menu for my setup. I have two hard drives one with WinXP and a second one with CentOS 5.3 installed. I basically moved the hard drive from another identical machine to this one and so I want to setup a boot menu to access either windows or Linux. CentOS already has grub on it.
What is the simplest method of setting up the dual boot menu? I would like something which is easy to administer which I can just ghost over either the Linux drive or Windows drive or disconnect either and have either boot just fine. I don't ask for much do I?
If I have to go through a little process after ghosting over one or the other drives that would probably be ok. We get updated images for this machine and replace the image on the drives with new images, although Linux shouldn't be reimaged, just windows. So the Linux drive (2nd drive) should not be touched normally.

I have an image generator (IG) running 64-bit Ubuntu Linux, GNOME & the SAGE application all running through an NVIDIA Quadra FX4500-X2 (dual GPU). Had to install a new FX4700-X2 (and the latest drivers) because 4500's are unavailable. The computer works fine except but I cannot watch the whole boot up sequence on the same DVI port anymore.On the 4500, all video came out the lower DVI port of the GPU with the PCI-X connector (let's call that the "a" GPU). But on the 4700 card, the screens you see during boot are divvied up between the lower DVI port of each GPU. The POST screen through Ubuntu splash screen comes out the "b" GPU while the "a" GPU is blank. The SAGE Initialization page and SAGE Desktop comes out the "a" GPU while the "b" GPU is blank.
I logged in as root and looked for a GNOME menu allowing me to force all video through the same GPU & DVI port, but couldn't find anything remotely close. Any suggestions on where I can look? Technically this IG is working, but I want to fix this to avoid future wild goose chases. The system uses 52 of these IG's.

I've used it once before but got fed up with the boot asking me everytime I turned my laptop on because I wasn't using it enough. I have Windows 7 on drive C . I want to keep it on drive C. I have several 1.5TB+ drives, and one of them is not being used. I want to dedicate it to Ubuntu, and be able to do a dual boot with my Windows 7 install. Is this possible? If it is, what about when this drive is not connected to my laptop? Will that mess up the boot process?

i'm tying to dual boot Vista64 (already installed) and Fedora 10 x86_64. I am running a Dell XPS 410 running 2 sata hard drives raid 0 (ICH8DH). I started the process by shrinking my C drive on disk0 leaving 64.45GB of unallocated space. Next I rebooted into Fedora install DVD and when i get to blue graphical install screen i get message asking if my drive is GPT and if it is it may be corrupted. I click NO, and it comes up with a message telling me i have to initialize my drive if i want to use it ( have to click NO twice) and if i do it i will lose all my data.
i can click no and keep proceding through the install until i get to the partition setup screen. No hard drives or partitions are shown. I've tried googling the problem and get bits of pieces of information scattered in different parts but nothing conclusive to my problem i think. As far as my background of knowledge goes, I'm new to the linux community but give me a thorough guide and i'll do fine (i hope). I've been using fedora on a separate laptop for 2 days now .

I have a Dell Dimension 3000, pretty boring. I've got 3 hard drives installed. One drive (C) has XP loaded onto it, one drive has Fedora 13, and one drive has all of my media and photography work on it.
I installed Fedora to play around with Linux, but now after a while, I've decided that I want to use it as my default OS. I haven't booted into Windows in who knows how long. The problem is, that when I boot the computer, it defaults to XP. The only way to get into Fedora is to press F12 at the proper time to select which drive I want to boot from. This is a hassle at times, because I have a tendency to forget and not hit F12 quick enough and have to start over.
Unfortunately, I'm not sure which bootloader I'm using, however I believe it is the XP boot.ini file, if I'm explaining this right. I tried modifying the boot.ini file in XP, but it seems as though the instructions I got are only when the two OS' are on the same drive in different partitions.
Want to make linux default OS in a dual boot system on 2 seperate hard drives

We're trying to replace XP with a XP/Ubuntu dual boot on a bunch of old desktops (P4, 512MB RAM) and IDE drives. Unfortunately I'm not old enough for experience with IDE drives and the whole master/slave thing
I do not want to install Ubuntu on same disk as XP and use GRUB because the transition needs to be seamless with as little margin for error as possible and enabling the users to boot into either OS on a separate disk So I've decided to plug in another old IDE HDD into each desktop and install Ubuntu on that. Each desktop is equipped with a Cable Select cable with clear Master and Slave labelling.
So what should I do w/ regards to the Jumper settings? What about bootloader? Should it go into the slave Ubuntu disk? Can Ubuntu be made master and then offload the booting to XP through GRUB somehow (whilst leaving XP's disks untouched)?

I am attempting to boot Ubuntu off of a USB drive. The USB drive was created via the USB creator in the .iso file dowloaded from Ubuntu. But for some reason when I go into my BIOS and boot from the USB drive, it spits out one line of syslinux and copyright information ending in "et al" and then a flashing cursor but doesn't go any further. I would provide a screenshot but that isnt an option at the moment with not being able to get past the first line of booting. Also, I have never used Ubuntu as this is my first attempt at running it and it is obviously not going the best.

I have Windows XP installed. And I also plan to install CentOS 5.4.I have two hard drives. Hitachi 500 GB and WD 500 GB.Windows XP is intalled on first drive And I plan to install Linux on Second drive. And since i find some contradicting and not understood by me posts. I have to be sure what to do. I can install Linux, then i can edit grub. and add there something like:
title Windows
map (hd0) (hd1)
map (hd1) (hd0)
root (hd1,0)
chainloader +1
When its on one drive as I understand it will definately work. But if its on 2 different drives. There is a problem that windows doesn't boot from secondary drive. So I find this article witch i cannot understand. Do i have to understand it? Or its wrong and bad decision.

I have 3 hard drives: one with vista installed on it working fine, one with 10.04 installed on it and working fine and the last is just a media storage drive. Currently I have been unplugging the windows or ubuntu drive depending on which OS I want to boot. What do I need to do so that I don't have to physically disconnect the drives and can just pick which OS to boot on power up?

I just started working with Linux over the weekend. I do have a working dual booting system but it's not configured exactly how I want it to be. Currently Windows 7 Ultimate and Ubuntu are on the same hard drive but different partitions. The Windows boot screen comes up and I can select Windows or Ubuntu fine. Grub comes up when I select Ubuntu and I can successfully select any choice in the menu and it will run properly.
Everything works great now so you may wonder why I even want to keep tinkering, well, it's not working how I want it to. This is what I want it to do. I want Windows 7 on disk 0 and Ubuntu on disk 1. I want each OS to have it's own hard drive. I want Grub to be the only boot loader that comes up with the option to select Ubuntu or Windows. I want to skip the window's OS selection screen all together. I can modify Grub, I've already done some of that on my work computer.
I've been installing from windows. Should I use a CD instead? Would that accomplish my goals without doing anything special?

I am facing a problem with my AT91SAM9260 customized board. Board is almost same as the evaluation kit.
I could download the binaries ( Bootstrap-v1.16, u-boot-1.3.4, linux kernel 2.6.20) successfully to the DATAFLASH/NANDFlash in my board by using atmel SAM-BA tool with usb/serialport/jlink.
Here I describe the problem.
When I power up the board, boot strap is not jumping to U-boot location, in the normal boot sequence and board stuck with bootstrap.
But when I disconnect/connect the JTAG USB cable ( provided with SAM-BA ICE) , it's jumping to u-boot location and booting the board properly. I'm getting the same error in NAND FLASH also.
I have tried one more test case.I copied bootstrap binary at the flash location, [location which is specified for u-boot binary] instead of U-boot.bin (location: 0x8400 in dataflash), I got continous bootstrap debug messages in my console. [ So can I conclude SDRAM doesn't have any problem? ]
Bootstrap code or U-boot code ?

Ok so first off my hardware Asrock 775dual-vsta Master and Slave hard drives on primary IDE Absolute Linux 2.6.33.3 ; Dos 7.1 (yes Dos 7.1 by itself no windows whatsoever) Absolute Linux=sda1 ; Dos=sdb1
Ok so I can't boot into dos from lilo boot menu. It boots fine however if I tell the bios to boot from the second HDD first (DOS). But it's inconvenient to tell the bios every time on power-up to choose the second hard drive as the first boot device. Here is my lilo.conf boot section
# Linux bootable partition config begins
image = /boot/bzImage
initrd = /boot/initrd.gz
root = /dev/sda1
[Code]...
Either way when I boot from the first hard drive (linux hard drive) and lilo pops up, I select dos and hit enter then nothing... It just sits there and ctrl-alt-delete can't reboot my comp as it's frozen.
I don't wanna have to tell the bios to select my dos hard drive as my primary boot device everytime I wanna boot dos. I wan't my linux hard drive to be my primary boot device and have my dos hard drive selectable from the lilo boot menu. Why can't I do that? What am I doing wrong? I thought this was easier than dual booting from a single hard drive?

I just tried to install OpenSUSE 11.3 on sda4 which is approximately the 2nd half of a 1TB drive, with a pre-existing Win7 installation on the 1st half. The installation summary (before it made any changes) told me "The bootloader is installed on a partition that does not lie entirely below 128GB. The system might not boot." Naturally, not keen on having a computer that won't boot, I aborted the installation.
Of course it's not below 128GB -- Windows is there.
Is there a workaround that is straightforward enough for someone who has very limited experience with GNU/Linux and isn't a comp-sci student?

After I complete a big project I'm working on I'm going to be wiping and re-doing my desktop machine, probably in the next day or three. I'm going to be setting up a dual-boot; my first in about three years. I'll be using separate hard disks for this, and installing Slackware second on the bigger of the two drives. When I've done this in the past I've used Grub; Is there anything I need to know or pitfalls I need to avoid doing it with Lilo?

I am trying to install ubuntu 10.04 on windows7.windows 7 was already installed.I ollowed these steps to install ubuntu 10.04.1)First i made some freespace in hard disk to install ubuntu using windows7 default options(By shrinking).2)I used USB drive to install ubuntu.I made it bootable using unetbootin.3)I followed normal steps install(language,area,keyboard,using manual partition i installed ubuntu in free space,etc).4)I got boot menu when it restarted.PROBLEM isAs long i use only ubuntu (boot into ubuntu --shutdown--boot into ubuntu --shutdown) it works well.
If once i boot into windows 7 and restart the system i am loosing boot menu options.The following error i am getting"no module name found Aborted.Press any key to exit".If i press any key,I guess its trying boot using internet and lastly it says Operating system not found and hangs.
