Plan to use GRUB for multiple booting to select the OS but only with luck have I got it partially to work. Windows 98 and Puppy 431 O.K on first HDD but Puppy 421 on second HDD /dev/sdb1 stops at error 21.

From what I can figure out, grub can not figure out which disk has my root file system. I checked the partition labels and they match the UUID that are in my fstab.
Currently I'm running 3 operating systems on my machine (in order of installation); Windows XP, Windows 7 and Fedora 14. Unfortunately, after I installed Fedora I'm no longer able to boot Windows 7/XP. When I select the "Other" option in the Grub menu, I get the following error:

I dualboot Ubuntu and Fedora in one hard drive. Below are the scenario.
First, installed Ubuntu 10.4 on the entire disk (40GiB of size). Then, shrink the Ubuntu installation to equal size to free up space for fedora.
Second, installed Fedora 13 using the option "Use free space on selected drives and create default layout". After the successful installation fdisk -l shows,
Code:
# fdisk -l

I've tried everything to solve this, been browsing the forums for the last 2 days and no solution has worked. So I got a new netbook (Samsung n150 dated 03/2011) it had ubuntu 10.10 installed but I already use ubuntu on my macbook so I'm trying out knoppix, I booted it from usb and ran the HD installer, it gets through all that and then installs grub ok, but when I reboot I get "Error 17: Cannot mount selected partition"
Things I already tried: Grub setup (grub, root (hd0,1), setup (hd0), quit) and every variation. *I tried removing the usb and setting the HDD back to first boot in the bios and then changing the menu.lst accordingly, still I get error 17. Below is the information just after boot with the usb still plugged in and set as first boot in bios.

i ran into this issue only because i wanted to learn. I was reading the book, linux troubleshooting and decided to give it a try.
1) I went to /boot/ and moved vmlinuz (kernel file) to my home directory. (/root/)
2) I booted, it didnt boot (as expected) and now the troubleshooting part begins.
3) i entered to grub config mode using c
4) When i press root (hd0, (tab) it gave me 2 partitions. hd0 which is my boot partition hd1 which is my '/' partition. Please keep in mind its LVM and not a physical partition
5) If i do this, root (hd0,1), and press boot, it gives the following error Error 17: Cannot mount selected partition
During my research i found that, LVM is not supported by grub, so kindly confirm me this ? is this the reason i am not able to access my root partition ? i am doing this on vmware so no issues, but just for the sake of learning, can someone tell me some way of restoring it without using any rescure disk (livecd, liveusb etc) ?
I'm trying to install Fedora for the first time on my Desktop. Unfortunately, upon restart once the installation is complete I get the following error:
Code:
This is from Fedora 12 x86_64 DVD. I presume that this obviously has to do with my disk selection during partitioning, during which I deselcted the two drives that I didn't want to be part of the install and left the one that I did selected. I also selected "use entire disk". The drive had copies of both Ubuntu and Windows 7 on it, which I expect were wiped out during install.
I know that the details are sparse...but that's all I did. I'm happy to go back into the installer to retreive any necessary information that may be needed/to reinstall.
I've downloaded Ubuntu 8.10 and I have installed it within ms windows. My first problem was when I went to boot Ubuntu and the graphics weren't right so I rebooted it with a different graphic configuration and it installed successfully. When I went to boot Ubuntu a second time to actually use it I got the following error:

I am trying to install my laptop in a triple-boot configuration with Fedora 10, Windows XP and Windows 7 beta. I did already installed them in that order. This is how it is layed out on the harddisk:
Now i want to use grub to present a menu at boot so i can select an OS. Because I installed XP last it boots straight into XP. I've understood i should be able to do the following:
All goes well until the last step (grub-install). It gives an error stating that /dev/sda doesn't exist, which is correct; It doesn't. I do have the "device" listed outside of the chrooted environment.
My question is: How do I get /dev/sda available in my chrooted environment?
Firstly, I'm ubuntu-naive so things may need to be explained painfully slowly. Secondly, I tried doing a search for similar problems but I had a hard time following the solutions so rather than just jump on another thread I figure i'd start a new one.I am trying to move on from XP and tried setting up 9.10. I did the LiveCD; followed the installtion prompts and installed, and restarted. Following restart I get the following;GRUB loading.error: no such diskgrub rescue>I've tried doing the boot info script lines but I keep getting "unknown command sudo" msgs.I can't get beyond this point.

I tried using following some instructions i found after googling for the problem:
Code:

set prefix=(hdX,Y)/boot/grub

but after the 5th step, i get another "error: out of disk" message. The odd thing is that I had an install of 10.10 on this laptop a month ago, and it worked fine. As a side note, I installed fedora 14 after this happened, which worked fine. Reinstalled ubuntu, and it was back to the same problem. I also tried installing with a kubuntu cd I had, to make sure it wasnt the install media, and had the same problem.
I am a novice in Linux but due to my academic requirement I had to install Linux (Fedora 8). I have 2 hard disk's (80GB & 20GB), on the first HD which is 80GB I have Windows XP and the other one I partitioned and installed Linux. Now the first problem is that, whenever I start my PC I get a error which says "GRUB hard disk error", however when I restart the machine it's fine and gives me the boot options.
Secondly, the HD containing windows was affected by virus so I had to format & reinstall XP. Strangely after that I am not getting any boot options and it's like windows is the only 1 OS running. But on windows the partition on which Linux is installed in intact. So I assume something is deleted maybe the Linux boot file.
I have a dual boot machine (Win XP + Ubuntu 9.10 on separate physical drives) which was working fine. I now want to replace the Ubuntu 9.10 with LinuxMCE which is based on Ubuntu 8.10. Using the LinuxMCE install disk, I did a fresh install of Ubuntu 8.10 over the top of Ubuntu 9.10 (repartitioning the whole drive). On reboot, I now get a Grub "no such disk" error. I have run the boot info script which produced the following RESULT.txt:
Code:

My system has Windows XP Pro SP2 installed on /sda1 and originally a 10.04 on /sdb1-3, now upgraded to 11.04. The Ubuntu system works fine (teething troubles with nvidia drivers on upgrade but fixed now), and the Windows system shows up in the grub menu, but when it's selected, I just get `GRUB Hard Disk Error' and nothing else. Windows installed properly, and booted successfully until I installed Ubuntu in the first place. I can still access the files on that drive from within Ubuntu.
I've tried fixboot in the Win Recovery Console, which sounded like it did something, but didn't fix the problem. This problem isn't new to grub2, by the way - I just haven't needed Windows in a year.
Just installed Ubuntu 9.10 and had windows 7 ultimate installed prior to installing Ubuntu. When I installed Ubuntu I partitioned off a section of the HDD that windows is installed on and installed to that new partition. Ubuntu boots and works great but ever since installed if I select windows to boot it just reboot PC all together. Tried making windows default and it booted windows once then went back to normal. I tried to follow suggestions on different post about running "sudo grub" but it is not a command according to my terminal.
View 7 Replies View RelatedI recently installed Ubuntu, my first experience with Linux, but when I try to boot a previously installed Windows 7 from grub, it reboots the system back to the grub screen. I can boot to Ubuntu.
I've been searching for and working on possible solutions for several days to no avail. There are some similar posts on various forums but few quite like mine, and solutions I've read haven't solved my problem. I tried booting to the windows 7 repair disk and selecting the repair start up option, but the message tells me no problems were found.
I am fresh to Ubuntu and am having trouble getting it to boot on my system. I normally run XP, but recently added a second internal hard drive and installed Ubuntu on it. The installation went fine and upon initial reboot I received -
GRUB loading. error: no such disk grub rescue>
I am wondering if there is an issue between two different operating systems upon boot. I am not familiar with GRUB commands.
Downloaded Ubuntu 10.04.1 Desktop AMD64, tried to install it to a cleand HDD using the whole HDD, i.e. gave it permission to use the whole HDD. Installation process appeared to run OK but when it came to the restart it just fired up the message
error: out of disk
grub rescue>
I've searched this forum and found numerous references to these error messages but cannot make head nor tail of the diagnostic suggestions. Apart from anything else they suggest strings of command lines which I don't understand and can't enter anyway since they don't correspond to my keyboard layout (if I hit > or ) something completely different appears on the screen). Is there someone here who can provide a step-by-step solution in lay language ? Or is there such a thing as a bootable file which can be downloaded and inserted into my CD drive to correct this problem ?
Fresh install of 9.10. Update all. The update froze at the very end: configuring grub-pc. I let it run like that all night before settling for a reboot while the update manager was still running. (The update also raised the kernel version.) After reboot, I tried the newer kernel [2.6.31-17-generic] at the grub menu and got this error:
Quote:
udevadm trigger is not permitted while udev is unconfigured.
udevadm settle is not permitted while udev is unconfigured.
svgalib: Cannot open /dev/mem.[code].....
And, cat /proc/modules gives me a long list of modules (too much to retype for now).So my hard drive is there. maybe some errors on the / home partition [sda6] and I can get to the root directory.
FYI: MS-win XP still boots fine from grub.
Just tried installing Ubuntu 10.10 from a USB device on my Windows 7 machine but something goes wrong. Far into the installation the computer restarts, asks me which operating system I want to start (it had already done this once before) and I choose Ubuntu. Then I get three alternatives:
Ubuntu, Linux 2.6.35-22-generic
Ubuntu, Linux 2.6.35-22-generic (recovery mode)
Windows 7 (loader) (on /dev/sdb1)
I pick the top choice, and get the following message:
ALERT! /host/ubuntu/disks/root.disk does not exist. Dropping to a shell.
If I start recovery-mode i get the same message. There's some text above the message that reads "new low speed USB device using ohci_hcd and address"... Could there be a problem with the usb-drive? If I remove the USB drive I get the message: Gave up waiting for root device.
I installed ubuntu on my internal hard disk I experienced a problem with Grub and I just formatted all the Ubuntu Partitions and convert their format to NTFS to restore my windows (I have a backup) but now despite of I format all the Ubuntu's partitions but in the boot time, the grub exist and the grub apear I want to know where does grub exist?

I am having problems with grub. Originally I was having trouble installing Service Pack 2 for vista and I made the fool's mistake of changing the active partition in disk management from the boot partition to the windows partition. This blew up grub. After restarting I was dumped at the grub terminal i.e.

so I thought okay, I will just reinstall grub. I ran setup (hdx,y) but now when I restart first of all the splash screen is different, rather then the blue background with the big words in white, fedora 11, it's black and I get a error saying unable to read any images. I can see the different OS' I have on the grub screen but attempting to load any of them gives me

I am currently running the Fedora 11 xfce spin live cd. From the terminal here, here is some information. sda3 is my fedora 11 partition I am not sure maybe it is because of ext4 but I can't seem to mount it using mount /dev/sda3 /mnt/xxxxx.

I have a Dell VOSTRO laptop that I use for windows Vista. I have an old disk drive that I put into a USB case and now I want to use that for a Debian system. I do not want to install grub on my laptops HDD, if I do I need to have the USB HDD plugged in everytime I boot and i find that a real pain. I installed Debian on the USB drive with no problem and when it asked where I wanted to install GRUB I picked the USB drive ( I think ). Now when I interupt the boot and tell it to boot from the USB drive grub comes up with the correct menu but when I pick Debian I get the following messages:
