General :: Boot Disk Recommendations For Grub And Ubuntu?
May 18, 2010
I'm still kinda new to linux. I've been learning my way around the command line and been experimenting with linux on a couple computers of mine. Occasionally after trying a few things, grub or linux won't load right. I've done some research on possible tools to help but I was wondering if any of the more experienced users had some recommendations for boot disk or tools to help repair grub and/or linux desktop/server editions.
p.s. I would also be interested in any fun and interesting tools, programs, and/or repository's that other users have found beneficial.

After completing the installation of Fedora-FEL edition, I cant boot from my hard disk. "No bootable device found " error appears.
I have one Windows XP & 2 Linux installation in my disk.
I tried to restore grub using "setup (...)" command.but same error repeats.
Even I cant restore Windows XP using "fxmbr" command in... recovery console .
But I can boot from that drive by "chainloader" command in grub. code...
Running above command in grub terminal boots my hard disk ("hd1" is my "unbootable disk")

I have a sata 320 gb with mandriva linux 2009.1 on it.And it is what curently atached to my cpu. It is shown as 'sda' in the partition table.I also have another 40gb hard disk with windows xp installed on it.It is shown as 'hda' in the partition table . Now what i want to do is attach this 40gb hard disk to my pc and configure grub on my 320gb hard disk('sda') so as to boot windows xp(which is residing on the second hard disk,'hda')Can anyone tell me if what im doing is feasible or not? If it is feasible,can anyone suggest me how to get it working. I know i just need to add 2-3 lines to my grub.conf, but dont know what exactly i need to write.

Edit: This is somewhat inaccurate, please see post #16 on page 2 for my actual situation
I'm more than a little confused by this. A little while back I had to reinstall my machine because I had a hard disk failure and I replaced my primary drive.Everything went perfectly smoothly, but then a couple of weeks after that when I rebooted, it dumped my into the grub rescue console
Code:
error: out of disk.
grub rescue>
So, I found a solution to the problem on these forums, rebooted perfectly fine, and thought everything was fine. Until the next time I rebooted, when it happened again. And now, every single time I reboot, I get the same issue.I have to do the following, each and every time I want to reboot - and i'm at a loss to explain why grub is borking itself every time.Boot off a live cd.Open a konsole window
Code:
sudo su -
mount /dev/sda6 /mnt
mount /dev/sda1 /mnt/boot
mount --bind /dev /mnt/dev
[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.

I have a dual boot System with Ubuntu 10.04 Netbook Remix and Windows XP SP3 on an Asus eeePC 1000HE. I had some troubles with updating kernels etc. and I ended up with following problem:
After grub reinstall, I am able to boot Ubuntu, also I can mount the windows partition properly. Trying to boot into Windows, I get the error:
Code:
It's all on one hard drive which doesn't show any errors:
Code:
Partition table entries are not in disk order
Code:
Some partitions don't show a file system because they are luks-encrypted.
As I mentioned earlier, I am able to mount sda1. I think the problem is that the Partition Boot Sector is corrupted, even though I am not sure if the ntfs partition is damaged at all or if GRUB is the problem.
As I said I had problems with a kernel update and therefore had to reinstall GRUB. I think, but I am not sure, that I accidentally installed GRUB on sda1 (the windows partition) instead of on sda. After I installed GRUB on sda again, I was able to boot linux and fixed sda1 with testdisk. Before, sda1 showed as four partitions (sda1p1, ... , sda1p4). I was not able to mount sda1 till I fixed it with testdisk. testdisk says the Boot Sector of sda1 is OK, so does ntfsfix.
Finally, an extract from my /boot/grub/menu.lst:
Code: ...
The Windows XP entry is added by myself. I don't know much about grub, so there might be the error.
I tried to keep it as short as possible (this is only the end of the story), I hope I didn't forget anything important. Please ask if there is something not clear.
I am in Tanzania with this netbook, so it is not possible to boot Windows CD and fix the windows partition with it, also I don't have a very fast Internet connection.
Is there a way to fix this without a Windows CD? Maybe it is just a dumb mistake in the menu.lst?

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 ?

I cloned F14 with Clonezilla from 80GB to 320GB hdd(both sata disks), and then resized the partitions with GParted.But I can not boot into fedora on the new/bigger disk, it stops and the display writes "Loading stage 1.5" if I remember corectly,I tried to fix it with the live cd but with no efect.
Then i found Super Grub Disk live CD, and with that i tried to use their fix, which was the same as with the Fedora live cd i tried before, again no efect.Then i played around with Super Grub, and found the option to boot GNU/Linux indirectly, and with that metod i got results, found my menu.lst file and chose the kernel i wanted and it boots into desktop.
But i would need a more permanent solution, because now i allways have to use the same procedure with Super Grub Disk CD to boot into my Fedora 14.

I am running a 14 disk RAID 6 on mdadm behind 2 LSI SAS2008's in JBOD mode (no HW raid) on Debian 7 in BIOS legacy mode.
Grub2 is dropping to a rescue shell complaining that "no such device" exists for "mduuid/b1c40379914e5d18dddb893b4dc5a28f".
Output from mdadm:
Code: Select all # mdadm -D /dev/md0
/dev/md0:
Version : 1.2
Creation Time : Wed Nov 7 17:06:02 2012
Raid Level : raid6
Array Size : 35160446976 (33531.62 GiB 36004.30 GB)
Used Dev Size : 2930037248 (2794.30 GiB 3000.36 GB)
Raid Devices : 14
[Code] ....
Output from blkid:
Code: Select all # blkid
/dev/md0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
/dev/md/0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
/dev/sdd2: UUID="b1c40379-914e-5d18-dddb-893b4dc5a28f" UUID_SUB="09a00673-c9c1-dc15-b792-f0226016a8a6" LABEL="media:0" TYPE="linux_raid_member"
[Code] ....
The UUID for md0 is `2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` so I do not understand why grub insists on looking for `b1c40379914e5d18dddb893b4dc5a28f`.
**Here is the output from `bootinfoscript` 0.61. This contains alot of detailed information, and I couldn't find anything wrong with any of it: [URL] .....
During the grub rescue an `ls` shows the member disks and also shows `(md/0)` but if I try an `ls (md/0)` I get an unknown disk error. Trying an `ls` on any member device results in unknown filesystem. The filesystem on the md0 is XFS, and I assume the unknown filesystem is normal if its trying to read an individual disk instead of md0.
I have come close to losing my mind over this, I've tried uninstalling and reinstalling grub numerous times, `update-initramfs -u -k all` numerous times, `update-grub` numerous times, `grub-install` numerous times to all member disks without error, etc.
I even tried manually editing `grub.cfg` to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `(md/0)` and then re-install grub, but the exact same error of no such device mduuid/b1c40379914e5d18dddb893b4dc5a28f still happened.
[URL] ....
One thing I noticed is it is only showing half the disks. I am not sure if this matters or is important or not, but one theory would be because there are two LSI cards physically in the machine.
This last screenshot was shown after I specifically altered grub.cfg to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `mduuid/2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` and then re-ran grub-install on all member drives. Where it is getting this old b1c* address I have no clue.
I even tried installing a SATA drive on /dev/sda, outside of the array, and installing grub on it and booting from it. Still, same identical error.

I had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?

I have Ubuntu 10.04 installed on an external Seagate FreeAgent 320 gb hard drive. I have windows 7 installed on my internal 160 gb hard drive. But whenever I just want to boot in windows 7, I get the
"GRUB Loading..."
"error: No such disk"
"grub rescue>"
screen. This only happens when my external hard drive isn't plugged in. How do i fix this? It hasn't always happened like this. I have a windows 7 install disk, but it never gives me the option to repair windows or go to command prompt.

Opensuse 11.4 seems to be creating problems with booting from USB devices. (I have read in a couple places that people are having similar problems.)
Every time I try to boot from a different live USB image, I see a GRUB screen flash and the hard disk starts to boot up. The only live image I have had success with booting was another OpenSuse 11.4, then I got the options to install or run live. I was thinking of just wiping the hard disk and seeing if that made a difference. Can I get into the grub limited command line, can i format from here? Is some other way of installing over the WAN from inside the Suse OS?

My computer has become quite strange the last days, last week grub stopped working and just halted at the grub prompt.
I can manually start the system by writing
insmod /boot/grub/linux.mod
linux /vmlinuz root=/dev/sda1 ro
initrd /initrd.img
boot
[Code].....
Note:
The system is a Ubuntu 10.04 based system on a old HP laptop.

If I use the super grub disk I can get to my ubuntu partition otherwise my windows partition boots automatically. I spent over an hour in the community documentation using the live cd to reinstall grub and nothing has fixed it. I think that grub is installed and the windows bootloader is just taking precedence.

i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

Problem: I have installed two Ubuntu servers, 10.04 32-bit and 10.10 64-bit, in a multi-boot environment (also have FDOS and WinXPsp3). The 64-bit will not boot because grub can't find the UUID for the disk with the 64-bit system.
Brief Background: Installed 10.04 LTS two months ago with no problems. 10.04 is in a primary partition on hda with FDOS.
Installed 10.10 (64-bit) in a new primary partition on the same hd. The install seemed to go ok, but the MBR and the fs on the 10.04 were corrupted; could not boot. Restored drive, and rebuilt grub.
Installed 10.10 on separate hd (hdb). In grub step all OS's were recognized so I pointed the grub to hda. Grub failed to boot.
Rebuilt grub from 10.04 on hda. All systems recognized but 10.10 will not boot because it says it cannot locate the UUID specified.
Compared the grub.cfg for both systems, the UUID specified for hdb is the same. Also, when I mount the drive for 10.10 on the 10.04 system the drive UUID is consistent.
I know I must be missing some thing, but I know not what. Have searched and can't find any clues. All other OS's boot ok.
Hardware: AMD64 4GB, 2 internal IDE drives (hda and hdb), 1 internal SATA (hdc WinXP), various USB and Firewire Drives (no bootable systems).

I am so fed up with my Sony HDR that is already obsolete. As I am a linux geek, I have been thinking on building my own media central. Reading various hardware support list gives some information about if a card works or not, but not if its good. Also, I would like to buy a card from a vendor that actively supports linux. Can someone recommend a really good DVB-T card?
I would need: DVB-T support.Radio as an option.Two or more channels, three seems like the maximum that I would ever need, but who knows. Doesn't matter if its one or two cards, as long as it works. CAM support. Additional card or built in. I have no idea of how this works actually, but I think the CA module must support mpeg4 too? HDTV/Mpeg4 support (Software is fine, I guess.) I would also need a good remote control (bluetooth) that not neccesarily needs to come with the card, and a decent fanless graphics card that handles hdtv on linux...

Assistance in choosing a no frills rolling Linux Distro. Over the past few months have gotten my feet wet with Mepis, Linux Mint, Ubuntu and other distros. I really like these Linux distros. However, I dislike the need to frequently "reinstall" a distro as often as every 6 months just to keep it updated.
My computer:
PC with 1.4 GHz Athlon
512 RAM
320 Gig hard drive partitioned equally between Windows XP and a Linux Distro.
My computer is used primarily as a jukebox connected to my stereo system, and for email, browsing, etc. I am not a gamer.I'm tired of Windows and its problems; malware, viruses, and currently if I upgrade to Windows 7, I'll need a new computer just to meet the hardware requirements when what I have works for my needs, but the XP operating system is becoming obsolete.

My foray into Linux is one of hopeful necessity:I have a friend who doesn't have any comp & whose son is leaving for the military. I have an old pc I was planning to recycle but instead would like to see if it can be put back into use.She has wireless service in her apt building which she would like to access. I don't know if the versions of Linux that are light duty enough to operate on such a low end machine still suwifi networking... (I will have to download it at home to a mac, burn it to cd & install from there)? Is it possible to install a wireless card into an old P3/128mb ram (IBM 6564/GL300) and get it working?
