my ubuntu installation has stopped booting after i deleted and again created one of my partitions (not the ubuntu partition but my data partition). but now when i switch on my netbook it says: error: unknown filesystem grub rescue>
i used gparted live to resize. this is my disk partition structure:
before doing this, my ubuntu partition was /dev/sda7, the swap partition was /dev/sda 6, and the data partition was /dev/sda 7.
I have a dual boot system with ubuntu 9.10 x64 and Windows 7. Everything has been working fine for a a long time but yesterday I tried to delete an unused partition through the Disk Utility in ubuntu (System->Adminstration->Disk Utility) and everything was messed up. I used to get the "Grub error: Unknown filesystem". I managed to create an ubuntu bootable usb and followed some tutorials for fixing grub but all i managed to do is to get another error: "Grub error: No such disc". After some experimentation i got "Grub stage 1.5" which gave me a grub> command prompt./dev/sda is the drive containing Windows and Ubuntu.
[ Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 0.97 is installed in the MBR of /dev/sda and looks on the same drive in partition #6 for /boot/grub/stage2 and /boot/grub/menu.lst.
i have changed from windows xp to ubuntu 9.10 in monday but yesterday i turned my pc on and when i get in my session all get freeze, i waited for an hour and it was the same so i turned it off pressing the on/off button of the cpu, when i restarted it it saysGrub loading...Grub failed: unknown filesystemGrub rescuei dont knoe what to do.PD:i removed windows, only ubuntu is in the PC
I had win7 on my laptop. Before sometime I install Ubuntu 9.10 and it worked fine. Bur later that I resize the partition using third party software. Now when I restart the system it is giving me an error GRUB Loading error: unknown filesystem grub rescue> I am not able to access the harddrive. I am very new to ubuntu.
I have been using ubuntu 9.10 for a month. i have it installed on a 5GB separate partition of a 80 GB hard disk with my XP installed on a C drive(a separate partition ofcourse) then i had to remove it from my PC so i boot my PC with a partition manager cd and directly formatted that partition of 5GB from that software now i am having this error on my boot of PC....
grub rescue> error:unknown filesystem
I have tried a lot of commands here on this screen and nothing happens...i want to go to my XP .... and can't loose my XP OS and other data as well on different partitions.....
there was ubuntu on my pc operating system but it is strange for me so i wanted to instal windows 7 on my pc. I inserted Window 7 disk and started to install it and i formated Ubuntu but the disk what i was using was damaged and it could not complite the installation and now i dont have any programs in my pc. Problem is that i got another disk but i cant boot anymore my pc, i select drive and stuff and then comes error.
error: unknown filesystem grub rescue- i tryed different commands but those didnt worked.
I had dual boot with windows 7 and ubuntu 10.04 running, and working. In my grub menu on startup I could choose (among things) something called Vista loader. Dont know why, since I installed windows 7 and not vista. Could also choose windows7 and ubuntu, both worked.
Today I accidentally pressed the vista loader, and now I get the following error upon boot: Error unknown filesystem grub rescue
So the next thing I did was download the latest ubuntu and boot from live cd. I followed instructions [url] on how to purge grub2 and reinstall it, and did so with out any problems. However the same error remains when I boot.
I just recently decided to install Ubuntu alongside windows 7 64bit. I was working fine until I decided to increase the partition size of the unused space to take up some space of an unused partition I had made earlier. When I tried to reboot windows I got the error - error: unknown fileystem. grub rescue> I have tried a windows repair disc with no results, it cannot find any problem with the startup routine and I have looked at many different tutorials and information about how to restore grub using command from the grub rescue menu. Ubuntu 10.10
I tried upgrading to 11.04 this morning and after rebooting grub left me at the grub rescue> prompt with the message 'error: unknown filesystem'. I've tried purging and reinstalling grub using a live-cd but no joy.
Let me know what additional information to provide. EDIT: Here is the output from the Boot Info Script
I have dual boot with Ubuntu 9.10 and Windows 7. Today, after using Partition Wizard on Windows to resize its partition, I got the following message when reboot:
I dont actually know what to do, I've been reading some threads on the internet but nothing equal to my case, only people who installed Windows after Linux and lost GRUB. Do I just need a live CD to reinstall GRUB? Can somebody tell what to do?
I have windows vista. i tried installed linux-ubuntu 9.10 but not knowing after a point on how to proceed further, i quit half-way. so my partition (14 gb)remained wasted. i tried installing again in a new partition and got it done. from my newly installed lunux, i tried to delete that 14gb partition. and now when i restart my laptop, i get this error :
I had a problem with my grub (system displayed "unknown filesystem" and then the grub rescue prompt). I then used a livecd of ubuntu 9.04 and ran fsck for a while (closed it in the middle). Grub then worked. But when i select ubuntu 10.04 it goes to the purple screen and stops there. There's some error before loading the purple screen.
Yesterday I installed the latest version of ubuntu to my computer that was already running windows 7. I had everything working fine until in windows I deleted a partition that had nothing in it. After this I restarted but I can't get into either OS.
I get an error that says Error: unknown filesystem grub rescue>
If I could I would change the boot order but I can't do that (I have a Dell Studio 1747). I try F2 to enter the BIOS set up, but I still end up with that error and never get to the setup. F12 doesn't work either (F12 is for the boot order) so I can't boot from the DVD with the Win7 installation DVD as the computer just freezes and I can't get past the Dell splash screen.
I have tried to remove the coin battery on the motherboard in an attempt to reset the BIOS but that didn't work either.
F2 = error F12 = freeze Reset bios by removing coin size battery = no change
I assume there is no use reformatting the HD by attaching it to another computer and re-install Win7. Is it a motherboard problem?
Just delete a linux partition and now when i boot a message appears and says error: unknown filesystem grub rescue >
I have search on the net for this problem and i have understand it a little. But my situation is a bit different and because i don't want to format my hard disc i wanna try to fix it. So before a couple months i download ubuntu 9.10 and i installed it a month later. But my computer used to crash all the time and i couldnt use it. So i download the latest ubuntu 10.4 and install it while having windows xp and the old ubuntu 9.10(so i had windows xp, ubuntu 9.10 and ubuntu 10.4 partitions). Now i tried to delete the partition of ubuntu 9.10 from disc utility. so i have the message i wrote above when i boot. I dont wanna delete my windows xp and ubuntu 10.4. what should i do to stop this message from appearing.
Background: My mother's HP laptop had Ubuntu and Vista on it, Ubuntu my brother's doing. He decided he wanted to take off Ubuntu yesterday (he had forgotten the password), and deleted the partition that it was contained within. The computer now boots to this error.
Inventory: We no longer have the install disk for Windows Vista, he cannot tell me what version he used of Ubuntu, what partition it was on, any of the specs for the machine, or generally any information about the system. All I am aware of is that error on the boot-up screen. I have nothing else to work with.
I would like to remove Grub, and Ubuntu, and leave Windows intact (the request of the owner of the computer), but I have no idea what commands I could use to get rid of either when I can't access Windows, or how to properly remove them if I did access Windows.
is it ever possible to do dual booting with grub(legacy) ever at all!. it is possible provided i take some pain, here is the link of that post [URL] i was coward and weak i didn't try that out then. but i did try it out. now so if u haven't seen the post .... I've installed Fedora 15 desktop(Gnome) with physical Logical volume called vg_fedora lv_root(ext4) ,lv_swap and lv_home(ext4), with 500MB /boot partition and had about 200GB free hard disk space ... so i wanted to install Scientific Linux 6.1 (because our school uses RHEL 6.1)
so, while running the installer I made (added) a logical volume lv_Scientific with ext4 FS and made its mount point (/) and used the MBR /boot which overwrote the Fedora /boot (completely OK and was as expected) i restarted after installation i got SL log in and as per the directions of the thread i copied the boot stanza from grub.conf of fedora 15 (which i already had copied and pasted into a text file and copied it from there)and pasted it into grub.conf of SL you may ask why did i choose same physical LVM too save swap space ... if i had made another physical LVM i had to make another swap ( i like LVM ... its cool)
completely unexpected happened Fedora now boots but not SL when grub starts i get this error 27 unrecognised commad and when i press <enter> i get grub menu with SL and fedora when i press on Fedora it works well i get my fedora login and i did login .. everything works fine but when i press SL it goes to the previous black screen grub error 27
I had Ubuntu and Kubuntu installed to dual-boot using the GRUB loader installed by Kubuntu. I mistakenly formatted the Kununtu partition to NTFS in an attempt to install Windows XP in its place without updating grub to pull the files from my Ubuntu partition.
Now, when I go to boot the computer, I receive a the "error: unknown filesystem" and the grub rescue prompts for commands. I've attempted to boot from both a Ubuntu Live CD and a Secured Ubuntu CD with boot repair built into it, but receive the same message both times. I know this isn't an issue with my boot order (I've changed that), and my computer will boot into a Windows XP setup disc (which will not proceed for a different reason)
I changed the first line of /etc/fstab in an attempt to get rid of an annoying message "mount: unknown filesystem type 'static'". All I did was put a "#" on the first line .... changing the original from:
Yesterday I partitioned my hard drive with kubuntu netbook remix and windows 7. after a few hours and reboots i turned on my computer and it said Grub loading. unknown filesystem rescue grub> It looks like allot of people have been having similar errors recently with windows 7.
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 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
I upgraded from 9.10 to 10.04 and during the upgrade it asked to install a new version of grub or keep the current one. Thinking that I should just upgrade the grub just to make sure that I had the latest version I decided to do it. So I told it the partitions to use the ubuntu, ubuntu swap, vista, and vista recovery.Finished the upgrade and restarted.I tried to boot into both the vista, and vista recovery but I noticed something weird. Grub switched the names, the actual vista install is called recovery, and when you tried to load it, a blinking cursor would appear for a split second and then loop back to grub. If you tried to select the vista recovery now called vista it would just sit at the blinking cursor for infinity. But booting into ubuntu worked.
So I decided to wipe ubuntu and do a fresh install of 10.04. Went through and set up the swap and ext4 partitions at the end of the hard drive(because I would like to expand the windows directory should I ever be able to boot into it). Now when I start up and select vista recovery now called vista it sits at the blinking cursor just as before.
I am trying to install ubuntu 10.04 lts on three of my schools old computers, they are all old Celeron computers, all basically exactly the same, it installed flawlessly on the first one but on the second after restarting after fresh instillation it boots to an error saying "unknown filesystem, grub rescue>" I've reinstalled 3 times, I've looked for others with the same problem but they are all related to dual booting with windows, I wiped windows, there is mow windows involved
I am fairly new to linux and my laptop froze so I rebooted it and now I have this error. I have tried to load the files needed using the prompt but nothing seems to work so here is my bootinfoscript thing. Any way for me to reinstall ubuntu over the sda5 partition but keep my files?

having a bit of a problem here. I woke up this morning, and my computer was froze. It does this from time to time, the monitor won't respond and wake up, flashing lights in the keyboard etc. Well anyways, I turned it off, then turned it back on, and it says:
