Ubuntu :: Dual Booting From EHD - Fallback If Drive Not Found?
Feb 23, 2011
I have managed to get a system going where I have kubuntu installed on a partition of my external hard drive. When the ehd is plugged in, everything works well. I have the option to boot into vista (my main os) or kubuntu. However, I see no reason why it won't let me have some kind of fallback mechanism that would let me boot into vista if the ehd is not found, instead I end up with the grub rescue prompt.
If not then I'm going to have to look at other options, perhaps booting into vista by default unless I hold down escape or whatever other key my bios expects to override, because there will be times that my ehd won't be plugged in. This is the only little niggle, as apart from that everything is working great.
i decided to install ubuntu in my PC,i downloaded the .ISO image and i installed it in my USB. After trying it and all that i observed that i really liked it and i decided to formally install it to my computer in the hard drive. When i reached the partition thing,i selected to dual boot with Vista and select between each them in every startup,when i clicked FORWARD it gave me an error which i did not read(because,again im a noob) so i clicked cancel.
Today i wanted to go through the process again and now really install it,so again i went to the time zone part and i clicked forward but then,instead of taking me straight to the partition phase,it appeard a window saying "The installer has detected that the following disks have mounted partitions: /dev/sda ...." I clicked yes,to unmount this partitions so it took me to the partition thing,once there i selected the option to install Ubuntu with Vista and select between them i neach startup,then i clicked forward and went to the username/computer name process,once i finished i continued to the next part,the installation,but i selected to import all of my WIndows VIsta default user data,after that i clicked forward and went to the installation process,i went down stairs to eat soemthing while it finishes,i came back and it was finished,it asked me to reboot so i clicked in Restart Now.
When it tried to boot,appeared an error saying: Error: no such devide found: #################### Grub load(or something like that) grub rescue: and it was a command line,since there i havent been able to boot into vista or Ubuntu,im really scared because is the first thing related to OS installing ive done,so i booted my USB and ran the trial and right now im trying to find out what to do from that trial version. I just went to the INSTALL UBUNTU 10.04 LTS application under the System>Administration Menu and found out that in the partition phase the Install and allow to select between both systems in eahc startup option,i dont know what to do,i foudn out that my HD has still all its data(MUsic/Videos/Folders/Programs/ect.)its just that i cannot boot from it. Also in GParted it appears as /dev/sda1/ and a warning icon besides it,also when i go into information, thers this warning there [URL]
I had a windows 7 professional on my computer. I tried dual booting it with ubuntu. While installing ubuntu when it asks which partition you want to install it "as it said your all data in the partition would be erased but not before you confirm" so I selected go back and aborted installation because I didn't wanted that and bang I start my system again an I get this error "no boot device found". I ran my hard disk test it say's passed so I don't think my hard disk is corrupted. I tried using windows 7 recovery disc but I guess it doesn't even detects a operating system on my laptop. I got no back up of my data. Any way to get back my data if I cant get windows back!
I have a 250 gig usb hard drive. I would like to install Mandriva and Open Suse 11.3 on it, is this possible and how do I get the systems loaded. I got Mandriva installed, but when I tried Open Suse it trashed my Mandriva, i.e. I couldn't boot into it.
How to put ophcrack on linux because of my supposed intentions of plugging it in waiting 20 mins and cracking passwords wherever people do this I know having to waste my space triple booting the thing with Ophcrack XP/Vista and BackTrack. How does one go about dual booting a flash drive? I could not find much on the internet.
I have a laptop with two partitions, one with Windows XP and one for storage (formatted in NTFS). I would like to install Ubuntu on the storage partition, but my problem is that I can't boot from CD (or anything else) because my BIOS is password protected. I obviously don't know the password. y question is: If I plug the laptop's hard drive into another computer, install Ubuntu as described above and then reconnect it to my laptop, will it work?
I'm going to install and dualboot pinguy os with my current install of Ubuntu 11.04.I'm stuck on the advanced partitioning part, how do I give Pinguy a 30GB hard drive?And does this involve creating a new partition table?
I am buying a new laptop and am curious about dual booting it. I currently run Ubuntu full time, but will need windows for a few applications. (there are no cross over applications to do this)
When you put both windows and ubuntu on a computer do you share the hard drive? Meaning would I be able to access all my music in windows and then restart my computer-run ubuntu, would I have access to all the files?
I can dual-boot on my PC by using my SATA drive for Windows & a second IDE (PATA) one for Ubuntu.However when I try to install both OS's on the Primary SATA drive side by side only one is detected (and I have no option to boot the other).
I have a friend with the same problem who is trying to boot Win7 and Ubuntu off the same SATA drive and the same issue occurs on his (He doesn't have the second drive as an option as I do).
Does anyone know a way to get side by side installation to work on one (SATA) drive? Failing this is it possible to boot Ubuntu off and External hard drive and still be able to dual boot Windows & Ubuntu?
I am running a hp dv701175nr laptop and am booting ubuntu 11.04 from a usb flash drive. I can not seem to find my internal drive that has windows 7 stored on it. I tried to mount it but it give me this error:
Error mounting: mount exited with exit code 1: helper failed with: mount: according to mtab, /dev/sdb1 is already mounted on / mount failed
I can't use this operating system if I can't access my windows 7 drive and I really want to use this OS .
EDIT: Okay, so I think I have found my problem, but I don't know how to fix it, there are differences in my mtab and fstab commands, I will post what they say in a second, but I do not know how or what I need to do to change and make the settings right
I installed 10.04 on daughter's laptop. It's been working perfectly but suddenly it's refusing to boot. Sadly, she's now half way around the world so I can't fiddle around to get it working. She's posted me a photo of the screen.
Here's what seems to be the important part: mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /sys on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Target filesystem doesn't have /sbin/init. No init found. Try passing init= bootarg.
I currently have a dual boot system with XP and Ubuntu 10.04 32bit.I need to do a complete reinstall of the XP and am thinking that this would be a good time to transfer Ubuntu to a bigger drive and maybe install the 64bit version. My computer is a few years old but the Core Duo should be able to handle 64bit.
I am wondering though that since I have an old printer, scanner, web cam, etc. whether I would have problems with my system running 64bit. I am also concerned as to whether the software in the library would work properly (if they are not 64bit).There is no pressing reason for me to run 64bit except curiosity so if it will cause problems I can wait.
Right now I have my hard drive partitioned, 1 with ubuntu 9.10 32 bit, and 1 blank. I was wondering if I could but a 64 bit windows 7 OS on the 2nd partition while the ubuntu partition was 32.
Better yet, is there a way to make my current ubuntu 64 bit?
I have an amd phenom ii x4 955 which is compatible with 64 bit OS but I accidentally used my old ubuntu disk with 32 bit on it.
I've just got a Toshiba NB 250 netbook pre-loaded with Windows 7.
I'm hoping to dual boot this (Windows 7) with Ubuntu. There are three partitions (sda1, sda2, and sda3) already created on the disk. I'm thinking of reformatting the sda3 drive to EXT4 and loading Ubuntu onto this drive. I'm not sure what's on sda1, but sda2 appears to have the windows 7 on it (though I'm not sure about that).
I am trying to dual boot xp and ubuntu 10.10 desktop. Everything in 32 bit. I have xp installed now and created a bootable usb with ubuntu and am trying it out now. i press install and then select my language. I then select install updates and third party software. I then get to a screen with 2 option erase disk and use that or specify partitions manually. I want the option that says install side by side, but it is not there.
I have windows7 installed on a single partition 500 gb hd. i want to install ubuntu as dual boot. (i have done this before but not with win7.) can i go into disk management and reduce the win 7 volume by say 50 gb. format it fat32 and install ubuntu. and still have dual-boot? thanks in advance. i plan on using either ubuntu 9.04 or 9.10.
i have a dual boot system set up right now through wubi. the installation went fine. but then i tried to upgrade ubuntu from 10.04.2 to 10.10. the update went fine, no errors. but afterwards when i restarted my computer and selected ubuntu, it said "error: file not found" it didn't even get to grub. this has happened numerous of times trying to upgrade in the past.
p.s: i have vista installed as the other side of the dual boot.
I am having issues booting my LFS system on my hp nc8230 notebook running LFS SVN. Grub was built and installed per the book. My file system is almost as simple as it gets:
/dev/sda1 is swap /dev/sda2 is my LFS partition /
The LFS live cd still uses the now deprecated drivers for HDD's thus as far as the livecd is concerned my block devices is (hd0) and /dev/hda2 for the root respectively. However the kernel to be booted runs on the newer drivers thus on boot my block device should be referenced as /dev/sda2 for the root. Grub is in fact installed on the MBR what happens is right when my system boots I get a file not found error the grub CFG is pointing to the correct block device and root partition from what can be seen by looking at the grub.
I have installed Red Hat Linux 5 and using it. But when I uninstalled one package and booting after that, I got the following error Error 15 : file not found
I have run into some serious problems trying to start up RHEL AS4. I am trying to install Oracle on this box which by the way is running as a guest OS through VirtualBox. I was running with it fine yesterday. I was doing the prerequisites of updating the /etc/sysctl.conf file with additional kernel parameters. Prior to that I added another scsi virtual disk and extended a PV and left it at that for the night. I am since come back today and trying booting and am getting the following errors:
Volume group "VolGroup00" not found; Couldn't find all physical volumes for volume group VolGroup00; Couldn't find device with UUID "Some UUID of the device"; ERROR: /bin/lvm exited abnormally! (pid 318); mount: error 6 mounting ext3; mount: error 2 mounting none; switchroot: mount failed: 22 umount /initrd/dev failed: Z kernel panic - not syncing: Attempted to kill init!
I have tried running in rescue mode and it can find volume group VolGroup00. I also have installed Storage Foundation which includes veritas volume manager and other various veritas components. Does anyone have a clue what I am supposed to do here to get RHEL up and running again? I am running kernel version 2.6.9-42.EL if that helps as well.
Just sucessfully installed a sual boot with 11.2/ubuntu 10.4. 11.2 was installed first, than ubuntu. ubuntu recognizes and displays 11.2 on its bootloader, 1..2 does ot show ubuntu on its boot menu. so this mean I have to edit menu.lst and physically add the menu entry (root, load the kenel, and load initrd)....correct?

i want to restore grub after installing xp my ubuntu version is 9.10 i had used this find /boot/grub/stage1 . with the previous versions but it didn't work with 9.10 what can i do ??
I've been using Ubuntu for a few months on my HP Mini. Windows has been destroyed, but now I want to use some of the programs from windows. Is there anyway to get a virtual windows or dual boot without a disc drive?
Until very recently I was running Ubuntu 9.10 (Karmic Koala) installed on a 20 GB hard disk and Windows XP (SP3) installed on RAID 1 array of 2 x 250 GB disks, very happily along side each other and using GRUB as the bootloader installed on the smaller 20 GB drive.
I have decided to upgrade to Windows 7, and was struggling with the installation failing with the seemingly quite common "Setup was unable to create a new system partition or locate and existing partition" error. Google seaching suggested unplugging my Ubuntu drive and then installing Win 7. This worked fine with the Ubuntu drive unplugged, however with the 20 GB plugged back in I can boot to GRUB, but it still has XP in the menu, and no option for Win 7.
I think I could get around the issue by re-installing Ubuntu, which would place GRUB on the MBR which is now on the 250 GB RAID 1 array, but I would rather have the system as it was before with GRUB and Ubuntu on the 20 GB drive.
I know I need to edit GRUB to remove the XP entry from the menu, but I have no idea how I would get Win 7 into GRUB, and what to do about the MBR which Win 7 put onto the RAID 1 array.
I'm using the latest version of EasyBCD (as of now) to dual boot Ubuntu with Windows 7. I added an entry "Ubuntu 10.04" to the boot menu, selecting Grub as the type.However when I choose Ubuntu upon startup I get this.Upon hitting any key I get this.Wanted to mess around with Grub and mbr, but I'm afraid I'll screw my hard drives up
