Ubuntu :: No Boot Device Found - Error When Tried Dual Booting
Apr 5, 2010
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 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]

Ubuntu 9.10 was set up to handle the booting selection - previously I thought it was xp but Ubuntu 9.10 "did" it. The system started out as a xp / ubuntu 9.10 dual boot on a 400gb drive. xp has 210gb, ub has 80 and their is a 100gb shared storage. Xp was installed first and then I followed a guide over at linuxconfig.org to get ub installed so that I could select which OS was wanted at boot. Ubuntu manages the boot up menu (Went back to look at my notes from the original setup) The owner tried to update to ub 11.04 and afterall was said and done the machine now boots to the message
error file not found grub rescue I can't say if 11.04 was properly installed or not. Ask whatever you like and I'll give the best answer I can. I think the xp install is okay but I can't say for certain as I don't know how to boot it outside the bootmanager at startup. Data has been saved so if I have to blow it all away and start over I can but I'm hoping I won't have to.

I had Windows 7 and Windows XP. It was 3 partitions in one HD (two OS' and one for files) and another separate HD (which doesn't have any system, it's just media files and stuff). When booted, I used to get the Windows 7 screen, that allowed me to either boot 7 or XP. I thought I had tested 7 enough and wanted to try Ubuntu, so I (from the Ubuntu CD which I downloaded and burned) deleted the 7 partition and made a 2GB swap partition, and, what was left, an Ubuntu partition on which I installed it.
Now when I boot I get an Ubuntu boot screen that shows several Ubuntu options and a WinXP option. Ubuntu works fine, but if I choose WinXP, I get "Error 12: Invalid device requested". I didn't change anything more than what I said. The details for the WinXP boot option seem to be:
rootnoverify (hd0,4)
savedefault
makeactive
chainloader++
What can I do to be able to boot WinXP again? (and also Ubuntu, whenever I want to). The only thing I can think of is using Windows XP CD's restore thing to restore the boot menu, but that would stop me from using Ubuntu...

Recently I've installed Open Suse 11.3 along with Ubuntu 9.10 on my PC ( made it a dual-boot OS ). This morning while logged in, in Open Suse 11.3, found out that there were important update for kernel in Yast. So, did the update and then required to restart the PC. In the Grub/boot menu, I chose to log-in to Open Suse 11.3, but after a while it returned with " Error 15, file not found ". Luckily I was able to log-in in Ubuntu 9.10. Assumed that Error 15 is always related to misplaced or wrong configuration of Grub in the partition, I did several searching via Google, and found this possible solution HowTo Boot into openSUSE when it won't Boot from the Grub Code on the Hard Drive . So I tried the " Broken Grub menu: boot to the menu, drop to a console and boot openSUSE direct " method. But rightly after the " find /boot/grub/menu.lst " command as instructed in the solution, it returned with ( hd0,0 ) and ( hd0,4 ). Why there are 2 bootloader in the Grub ? Which bootloader should I choose ? And for convenience, here is my " menu.lst " folder that I get via Terminal in Ubuntu 9.10 :
$ cat /boot/grub/menu.lst
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),

It's been a real battle, but I am getting close.I won't go into all the details of the fight that I have had, but I've almost made it to the finish line. Here is the set up. ASUS Z8PE-D18 mother board 2 CPU, 8 Gig Ram. I recently added an OCZ Agility SSD, defined a raid 1 virtual disk on the 1 terabyte WD HDD drives, which will holds all of my user data, the SSD is for executables.The bios is set to AHCI. Windows 7 installed fine, recognizes the raid VD just fine.
I installed Ubuntu 10.04 by first booting into try and mode, then opening a terminal and issuing a "sudo dmraid -ay" command. Then performing the install. I told it to install the raid components, and told it to let me specify the partitions manually. When setting up the partitions, I told it to use the free space I set aside on the SSD from the Windows 7 install as ext4 and to mount root there. Ubuntu installed just fine, grub2 comes up just fine, and Windows 7 boots with out a hitch, recognizing the mirrored partition as I indicated previously. When I tell grub to boot linux however, it pauses and I get the "no block devices found" message. It will then boot, but it does not recognize the raid array. After Ubuntu starts up I can run "dmraid -ay" and it recognizes the raid array, but shows the two component disks of the raid array as well. It will not allow the component disks to be mounted, but they show up which is annoying. (I can live with that if I have to)
I have fixed a similar problem before by setting up a dmraid script in /etc/initramfs-tools/scripts/local-top ... following the instructions found at the bottom of this blog:[URL].. To recap: My problem is that after grub2 fires up Ubuntu 10.04.1 LTS (Lucid Lynx), it pauses, and I get "no block devices found" It then boots but does not recognize the raid array untill I manually run "dmraid -ay". I've hunted around for what to do but I have not found anything. It may be some timing issue or something, but I am so tired of beating my head against this wall.

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.

XP and Ubuntu are on different drives and they were booting ok prior the the reformatting. With the Ubuntu drive selected as the 1st hd boot device in Bios: I can boot into Ubuntu ok if I select it in the Grub2 menu If I select XP in the Grub menu I get:
"error:no such device c8e4918ce4917cfe"
If I select the XP drive as the 1st hd boot device in Bios I can boot straight into XP.So that is ok. This thread: [URL] has given me a clue that: "The UUID listed in grub.cfg is wrong In some cases the UUID in the above search line in grub.cfg is wrong. This can for example happen if the UUID has changed due to formatting or partitioning. Bugs The "search" function is plagued by various bugs (see [1], [2]), causing the search to fail."
However the fix in that thread gives me this result: "At the grub menu at boot up (you might have to hold the "shift" key or press "Esc" to get to the Grub menu) select the OS you are trying to boot. But do not press "enter", press "e" instead to edit the menuentry. Delete the line
search --no-floppy --fs-uuid --set 86d32ee3-aec6-490b-8dab-e5cfff9c7af9
and then press "Ctrl+X". This should boot your OS. If you were not able to boot into you OS, you are infected by a different problem and should not continue this howto." My Boot info script results are:
Code:
============================= Boot Info Summary: ==============================
=> Windows is installed in the MBR of /dev/sda
=> Grub 2 is installed in the MBR of /dev/sdb and looks on the same drive in

The problem is that I need to use windows as well every now and then for gaming. So I have an internal hard drive dedicated to windows out of my laptop and one inside for kubuntu. Changing hard drives out every time I game is a bit of a bother and wondered if anybody has booted into windows without fiddling about with the hard drives. Can windows be booted from outside the laptop? (e.g. by using a sata to USB converter frame)?

Hey, im new to linux but i like it very much. recently built decent computer and put Mint 10 on it. every thing works fine but get a strange message after I install the driver for nvidia video card. Message is an edac error "device not found" E7xxx.? Not sure of any of it. System still works fine. Graphics are working great. Also the linux mint boot screen changed to some generic looking screen that says Linux Mint 10 in an old dot matrix type format.
Here's what I have:
Tyan i7501 s2735
(2) 2.4 Xeon cpu's
320 gb seagate hd
2gb ram
8400 GS Geforce 512mb video card

UPDATE2: As of 2 weeks ago, it won't boot at all. UPDATE1: HDD booted OK, but I don't know how to copy the GRUB file. Could this be a hardware temperature problem? I have just replaced a Hard Drive, & had to reinstall XP & 10.04.2LTS from scratch, (it was a TOTAL failure) The system now will not boot into XP, or either of the 2 Linux kernels or the recovery modes, without several attempts. ( I'm using a LiveCD now.)
POST is good. GRUB loads, but when I select an OS, it powers off. Windows shows the splash for a few seconds, then shuts down. Yesterday, I was able to boot into Linux after booting into Windows, but today Windows won't boot either. On examining the GRUB menu (e) the first line in the Linux records is 'recordfail' I will attempt to boot from HDD now, & post the GRUB output here. EDIT: If I run MEMTEST first, up to Test6, it boots normally.

I'm dual booting Windows 7 and openSUSE. I attempted to start up my computer, and got ERROR 17 on the GRUB loading page. I am assuming this is related to me disabling the openSUSE uninstaller on startup in Windows.installer seemed completely superfluous.

I am thinking about installing Ubuntu dualboot with Windows 7. However, I feel that it'd be a pain to select Windows 7 constantly as it is my main OS for work and school. Ubuntu would be for offtime tinkering and as such probably booted once or twice a week at most. I intend to use the system to use the OS not to use it for serious work. Before I install would it be possible to install it in Dualboot while maintaining the ability to boot W7 by default unless pressing a special key to come to the Grub bootloader or something like that.

I am having trouble getting FEdora 15 running on my MacBook Pro. I had Fedora 15 installed before on this MBP before, so I know it works. I basically followed the good old instructions of
1. Create a Windows partition in bootcamp (rEFIt was already installed from trying to get ubuntu running)
2. Boot from disk and install in Windows partition with bootloader on installed on the / partition
3. Install, reboot, and resync the MBR using rEFIt partitioning tool
4. Shut down the computer and start up on the parition you installed linux on
Now I get a grub error code...

Have a little experience with backtrack 4, which is a Ubuntu distro. I'm changing to Lenny due to hardware limitations on my laptop, an older Dell inspiron 7000.
Here's the specs :
400 MHZ,
120 G HDD parted as C: = 20G (has bad sectors, left blank) and D: = 20G Windows part
128 Mb low density RAM
ATI Rage Mobility ( not sure of video RAM, I think 8 Mb)
Now I liked running BT and liked the linux work, so when the BT install went south I started to look for another linux distro I can run, the BT tools I use are linux after all. Here's where I hit my stump. I decided to go with the Lenny distro, it already has some of the tools I need, but the first time I installed I had the HDD like this 20G, 20G, 20G,20G, 17.??G. I had windows installed on C: (of course, no problems, yet)
After I installed lenny to D: via an iso I downloaded, the Debian GNU/Linux 5.0.6 "Lenny" - Official i386 xfce+lxde-CD Binary-1, BTW first install was from booting from the disk. After reparting, format, etc. of the install, GRUB boot loader detects my D: Windows, great. Reboot to GRUB boot menu, select ddebian, and it loads...cool, until I realize I don't have synaptic, the tools, and apt isn't going to work unless I can load the linux driver from the cdrom...which I can't find.
Reboot...windows, internet for answers I'm thinkin. GRUB loads fine, select windows and get the following error message "Windows can't start because of hardware configuration problems. Could not read from selected boot disk, check boot path and hardware. Check configuration manual for disk configuration."
It took three days to get Windows reinstalled, and a LL format (zerowrite the drive) but during the process I discovered a possible hdw issue...bad sectors on the C: hdd. Solution: C: 20G = unused, D: = Windows xp. Worked great. No more windows issues, so try it again. This time I used the disks installer from windows. Everything started great, boot menuselected debian, install-graphic, but this time I let the part manager create a drive, 20G from the free space an it appropriately made it's swapfile...when lenny booted it was good, but still no synaptic, cd/rom, couldn't browse the computer.
Reboot to windows to get instructions from someone that really knows what's going on...no windows. exactly same message as before. I was able to boot into debian okay, but couldn't find any drives, utilities, wasn't very much, but I needed my windows and the internet to get lessons. I am familiar with the terminal console and KDE. Can use apt for updating, but prefer using the synaptic. Why does my windows keep disappearing? If I can solve the dual boot issue I can learn the system casually. Right now my config is: C: = 20G, nothing here, still haven't run a scandisk either...next on todo list. D: = 20G Windows install...what I'm using now. I'm not going to attempt to reinstall debian until I receive a efinate answer to the dissappearing config, or boot capacity. Oh, yeah, Did try a fdisk/mbr and fix. this didn't bring it back either.

i'm trying to install 98se to a 110gb partition so i can dual boot with ubuntu 10 for 98 and 100 for ubuntu after the resize. when i tried making multiple partitions manually for ubutnu putting it on separate partitions i got grub boot errors. the problem i am having every time i try to install 98 it forces me to scandisk it then i have to hit space bar to fix every error i thinks it finds wich is impossible to press it 2 million times. now if I format in a non 98 format and tell it to format in lba it keeps asking for a boot disc, i burned one off but, still kept asking for it. if i do it in non lba, it only saw 2 gigs in 98 and when i went to install ubuntu it was a giant hard drive no partitions. i did try making 3 fat 32s 1 for 98 and then swap and linux partition but, the i got grub errors 17 and 18.
the problem is that bios a cap of 130gb for each drive or in this case partition. it's 320gb WD blue Scorpio. the short i want to dual boot 98se and ubuntu 9.04 with 2 fat32 partitions for storage 110 +100 + 80 = 320 also some visuals.

I'm not consistently able to boot into Ubuntu Lucid on my new dual boot (w/ Win7) setup. Machine is a Dell XPS 1645 laptop. Usually it takes 1-3 tries of hard shut down and restart before the OS starts up. Boot info script results are below. Windows starts up fine everytime. What I usually get is this: Dell startup screen, then Grub2 menu, then after selecting Linux kernal a blinking cursor at upper left of monitor and it just hangs.

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?
