I switched to the linux-image-rt kernel a while back, and decided yesterday to switch back to linux-image-generic. Unfortunately, I couldn't remember how to do this properly, so I just uninstalled all of the linux-rt related packages and then changed the /vmlinuz and /initrd.img symbolic links back to what they used to be and rebooted. So now the machine gets stuck in a memtest whenever I boot from the HD. I'm having trouble figuring out how to fix things from a rescue CD. If I try chroot /mnt/hd (where my old system was), and then update-grub, for example, I get: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). So, basically I'm completely lost, but also sure that a working system isn't more than a few simple commands away. Can anyone throw me a bone?
I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:
[Code]....
I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:
managed to get things working so well on my laptop i thought i'd install ubuntu onto an external drive so i can boot to either xp or Ubuntu whenever i want, when i started up after the install it doesn't recognise the drive i loaded it to and appears to have lost the link to xp. the exact words are:
error: no such device: 4368f21f-d1b6-4c60-8c6b-4d2d38d16920. grub rescue>
what i can do to get my xp back, my wife uses the xp and will kill me if i don't sort it, fortunately the comps unrealiable anyway!
I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:
when it comes to linux, but like the idea and hope one day to get away from microsoft all together. This is the second time I have tried to install ubuntu on my eeepc 1000HG in addition to windows 7. The first version was karmic koala netbook remix, and yesterday it was lucid lynx netbook remix. Its annoying because before the update packages are downloaded and installed it runs smoothly, even additional applications run with no problem, but after restart to complete installation the following error message appears.
error: no such device: 5290ea6f-1bdf-4eda-b56e-2f282662e188. grub rescue>
I am dealing with a problem which I cannot seem to fix myself.I have a computer (age ~1 year) on which I am trying to install Ubuntu.The problem which I am facing is at the point of choosing to boot from the CD it says 'cannot find bootable device'.Note that this PC does not have a floppy drive and that I do not have a 1GB USB stick. I do have a 256MB USB stick.
Reboot and select proper boot device or insert boot media in selected boot device and press a key. I got this error after: Reducing my Windows 7 partition by about 100gb. Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted. I now had two partitions a new 100gb Ubuntu partition and a 600gb (or so) Windows 7 partition.
All of this was done using a bootable USB with Ubuntu 10.10 and GParted partition editor. Now when I boot I get the "Reboot and select proper boot device or insert boot media in selected boot device and press a key." error.
From one day to the other my system stopped booting properly. Since I (finally) fixed it, I wanted to share my solution. It runs on a fakeraid pair of SSD's of 60 GB each (actually a single Revodrive device, but it shows up as two devices). When Ubuntu 10.10 boots, I'm dropped to a shell.During boot, when I removed "silent splash" from the kernel's command line, I got these messages:
I doubt that this is what was needed (as I had that already when it didn't work, but I might be required in addition to installing dmraid)
# update-initramfs -a
After installing this, the problem was solved!! This is strange since I don't recall uninstalling this package or changing anything important, for that matter (perhaps did apt-get upgrade, but that's about it!). [URL]
I installed ubuntu today by installing Wubi and after downloading i rebooted computer and selected ubuntu but i got an error saying 'Try (hd0,0): FAT16: NO WUBILDR' and there was few more but i forgot and at the end it says 'Cannot find GRLDR in all device Press CTRL+ALT+DELETE to restart'. it used to work when i had vista...
I installed Debian Jessie (netinst, daily snapshot) on my Acer Aspire V5-123 laptop in the UEFI mode with the secure boot turned off. everything (network, hardware, partitioning, ...) went smoothly to the last step, but after removing the boot media (USB stick) and rebooting, the firmware could not find the boot device ! The only thing I can think of, is that the EFI boot is not set up properly by Debian installer, but I don't know how to fix it.
After upgrading to 10.04 from 9.10 Win7 wouldn't startup any more. So I tried this HowTo: [URL] to restore Grub2. But now each time I boot up I get this two lines: error file not found grub rescue> I have NO idea what to do.
I had a a problem booting last night when my laptop battery came loose and caused a crash during boot.It ceased loading a daemon and I turned it off with the power switch, then I received the boot error,then i checked the linuxdrives directory and it was corrupt,I then, out of ignorance, ran wubi from within windows XP and said unistall believing that it would reinstall and fix itself.Thus you can see my green behaviour.I have been searching the threads and have tried many things but have had no success, I will suffer a great loss if I lose that load of Ubuntu as I have allot of work stored there, and in my Thunderbird accounts.
I installed from a live disc months ago. It worked fine for a while, don't remember what caused the change.
Now when I boot, I get this message:
Quote:
I have several hdds in this desktop box, one other has a OS on it, has the Hardy version. But i disconnected that (it all used to work with both drives connected and I was able to use that boot menu to change from one OS to the other). I can boot by getting to "boot menu" by pushing the "esc" key when the bios starts (just after the beep). It gives the option to start from, with a list of possible devices to choose from. I don't know where this menu is from, bios or other. I select hard drive, then select the correct hard drive and it starts right up. That is nonsense though. I really no longer need version 8.04 but keep it as a backup in case my preferred OS/hdd fails.
After using Hardy on this machine for the past 2 years, I figured maybe it's time to try Lucid. So I burnt a Lucid live cd, and get the following message:

Pressing keys has no effect. [b]Ctrl+Alt:F[i]n[/n] doesn't do nothing.Nor does anything else I try. If I click on the Reboot button, it ends up wgere it started. Ogh, and the numbers 104280EF are also on the screen.
There's also a pretty picture accompanying all this: something that looks like a very small spreadsheet, and a stick-figure in a circle and... and I don't know what the heck is going on.
My Lucid LTS Ubuntu Studio 64 (amd) won't boot anymore; / and /home each are software raid 0 partitions.
I have a Multimedia partition (also ext 4) which I attempted to chmod with a GUI program (I forget what its called now) to enable all users read/write access. Looks like I inadvertently fstabed that partition to be mounted at boot-time (normally my password was required in order to mount it).
I tried to logging out and back into my OS to see if the partition was now writable but it wasen't; instead a filesystem error was noted. I realised then that my partition was IMPROPERLY labelled and I was in a tired state and didn't remember how to rename it & rebooted to make sure all was ok. But it was not:
An error occured when mounting /media/Ubuntu unknown filesystem type "Multimedia"
Boot: recovering journal
From my generic Ubuntu system on a non raid partition, I finally removed the space in the 'offending' partition: Ubuntu Multimedia to UbuntuMultimedia. And I changed the permissions for it.
But if I try to boot Ubuntu Studio via recovery; booting in low res is unusable, and it gets stuck if I SKIP mounting. So I am left with manual boot or drop to a shell. I will have to use an editor like vi or nano and the command prompt. I know that I likely only have to comment out a line in etc/fstab but I am only familiar with nautilus or gedit for this type of operation. And since this OS is on a raid partition its not 'seen' on the live CD....
I would need someone to offer me clear steps to follow with the non gui editors otherwise I'm in trouble...
I just wanted to use that partition for video editing and now I am locked out of my system!
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!
Today I installed Fedora (I need it for school), but not everything seems to work fine Before installing Fedora on my Macbook I had a triple booting machine: Mac OSX snow leopard, Windows 7 and Ubuntu. (using rEFIt) All of them where working. Since I installed Fedora on the 4th partition I can only boot Mac OSX. When selecting one of the other OS's it says: "no bootable device insert boot disk and press any key"
When I boot off of Debian Kernel 2.6.26-2-686. This is what happens. It stops at attached scsi generic sg5 type 0 After 4 or 5 minutes it comes back and says.
Gave up waiting for root device. Common problems Boot args (cat /proc/cmdline) Check Root= (did the system wait for the right device) Missing modules (cat /proc/modules; ls /dev Alert /dev/sdd8 does not exist dropping to shell /bin /sh: can't access tty; job control turned off If I boot off Debian Kernel 2.6.26-2-686 (single user mode) Then use Control-D it boots fine.
Recently, I created a device sc0 through device mapper. The divice could be found in /dev/mapper/sc0. My problem is that the device doesn't exist in /dev/partitions which will block my following test.BTW, I found dm-0 in /dev/partitions. Is it the same as /dev/mapper/sc0? But the device /dev/dm-0 doesn't exist!
i downloaded backtrack 4 (final) and booted the iso onto a flash drive using unetbootin. i then changed the boot order so the flash drive was first. after i did that i got into backtrack 4 did the install.sh and now i cant boot windows 7. even after changing the boot order to default, i turn my computer on and get a message that says:
Ubuntu 8.10, kernel 2.6.30.9 Ubuntu 8.10, kernel 2.6.30.9 (recovery mode) Ubuntu 8.10, memtest86+ Other operating systems : Memory Test (on /dev/sda1) Ubuntu 8.10, kernel 2.6.30.9 (on dev/sda1) Ubuntu 8.10, kernel 2.6.30.9 (recover mode) (on dev/sda1) Ubuntu 8.10, memtest86+ (on dev/sda1) [Code]....
i can only boot backtrack 4 OS, i really want to know what can i do to be able to boot my windows 7 home premium os.
just installed ubuntu 10.10 on my external usb hdd from my 8gb flash drive doing this on a laptop, my primary hdd (internal) is running windows (230gb of 250gb used) so i got an external hdd (2tb) and I decided to install ubuntu on it
I've been using an install of Ubuntu on Windows XP on my netbook. Iworked fine until recently, when I tried to boot into Ubuntu I got an error message reading:
Try (hd0,0): FAT32: No WUBILDR Try (hd0,1): NTFS5: No wubildr Try (hd0,2): invalid or null Try (hd0,3): invalid or null
Error: Cannot find GRLDR in all devices. Press Ctrl+Alt+Del to restart.
I've checked for the wubildr file and it's in its usual place on the C: drive, yet I still get this error message.
I had a working dual boot Ubuntu 10 and Windows 7. Anyways long story short, I got it working again but have lost the boot option for windows 7. If i run fdisk -l, I get the following.
I installed gparted and can see that windows 7 is installed in dev/sda6. In another forum, i read that someone had to edit their menu.lst so i did with the following.
I had Ubuntu installed, i installed Debian and there was no dual boot. So i formated all the hard disk to install only Debian. It installed but at boot i get error: no such device and the grub rescue> prompt. i googled for a solution and nothing worked:
- i tryed reinstalling grub, not worked - i did the windows cd fixmbr trick, not worked - reinstalled debian with fixmbr the first step and nothing - tryed deleting with dd the mbr, not worked - reinstalled grub from debian rescue, not worked
what should i do? i can't access my computer? please tell me how should i fix it? the google guys will kill me because i put their servers on fire
I have a Feadora 12 Live CD. It booted up fine on my 700 Mhz computer. I've since then put a new HDD in with which I intended to install Fedora on. But now i get this message

No root device found. Boot has failed, sleeping forever
What does this mean? How do get the Live CD to boot?
I recently installed ubuntu on an external hdd. i tried turning on my laptop w/o the hdd connected and when it went to boot it gave me an error saying that it couldnt find grub. all i wanted to do was boot into windows 7. is there anyway to set it up so i can just boot off my main hdd for windows and use the bios and choose to boot off my external to boot grub and choose what i want to boot like say linux?
I am having issues with 3d I am trying to start up a game called auteria but it displays this error "Could not find a compatible opengl display resolution. Please check your driver configuration. (Error: Couldn't find a matching GLX visual)" I am on ubuntu 10.10 could anybody give me a solution on how to fix this issue?
I installed Xubuntu 10.04, and it was working somewhat smoothly(little drivers, but I could see and hear). Ran the update(as of 3 hours ago), and started up the machine. Here is what greeted me.
