I believe I installed Ubuntu over Windows on my Acer netbook. I then tried to install Linux Mint, but it wouldn't start deleted ubuntu partition grub rescue installing. I turned the netbook off and back on. Now I get the error. I have read a lot of other questions like this, but in my case I cannot boot a CD.

Error Unknown Filesystem Grub Rescue Windows 10
works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Grub rescue - error: unknown filesystem up vote 40 down vote favorite 16 I have a multiboot system set up. The http://askubuntu.com/questions/142300/how-to-fix-error-unknown-filesystem-grub-rescue system has three drives. Multiboot is configured with Windows XP, Windows 7, and Ubuntu - all on the first drive. I had a lot of unpartitioned space left on the drive and was reserving it for adding other OSes and for storing files there in the future. One day I went ahead and downloaded Partition Wizard and created a logical NTFS partition from within Windows 7, still some unpartitioned space left over. Everything worked fine, until I rebooted the computer a few http://askubuntu.com/questions/119597/grub-rescue-error-unknown-filesystem days later. Now I'm getting: error: unknown filesystem. grub rescue> First of all I was surprised not to find any kind of help command, by trying: help, ?, man, --help, -h, bash, cmd, etc. Now I'm stuck with non-bootable system. I have started researching the issue and finding that people usually recommend to boot to a Live CD and fix the issue from there. Is there a way to fix this issue from within grub rescue without the need for Live CD? UPDATE By following the steps from persist commands typed to grub rescue, I was able to boot to initramfs prompt. But not anywhere further than that. So far from reading the manual on grub rescue, I was able to see my drives and partitions using ls command. For the first hard drive I see the following: (hd0) (hd0,msdos6) (hd0,msdos5) (hd0,msdos2) (hd0,msdos1) I now know that (hd0,msdos6) contains Linux on it, since ls (hd0,msdos6)/ lists directories. Others will give "error: unknown filesystem." UPDATE 2 After the following commands I am now getting to the boot menu and can boot into Windows 7 and Ubuntu, but upon reboot I have to repeat these steps. ls ls (hd0,msdos6)/ set root=(hd0,msdos6) ls / set prefix=(hd0,msdos6)/boot/grub insmod /boot/grub/linux.mod normal UPDATE 3 Thanks Shashank Singh, with your instructions I have simplified my steps to the following. I have learned from you that I can replace msdos6 with just a 6 and that I can just do insm

free trial of JIRA Service Desk and get your Konami Code shirt. On this page How it looks? Basic commands available. The Rescue Shell. After Booting the system. As GRUB 2's ability to fix boot problems has greatly improved over the original GRUB bootloader. This article provides you with information on available options for repairing GRUB 2 boot issues and specific instructions on how to use the GRUB 2 terminal. The instructions are written for GRUB 2. How it looks? There are basically three error messages or screens when GRUB fails to boot. grub>: This is the screen mode you see when GRUB has found everything except the configurationn file. This file probably will be grub.conf. grub rescue>: This is the mode when GRUB 2 is unable to find the GRUB folder or its contents are missing/corrupted. The GRUB 2 folder contains the menu, modules and stored environmental data. GRUB: Just "GRUB" nothing else indicates GRUB 2 failed to find even the most basic information needed to boot the system. These are the basic errors that may occur during booting. Although there are a few more errors that can be seen on the screen like frozen splash screen, Busybox or Initramfs: GRUB 2 began.... But each of the GRUB 2 failure modes can be corrected either from GRUB 2 terminal or the Live boot CD or DVD of the distro, there are also 3rd party rescue tools available out there. Basic commands available. These are the commands that can be used when you enter the GRUB 2 terminl mode by pressing "c". boot (Initiate the boot, also F10 or CTRL-x) cat (view the contents of config or txt files; cat (hd0,1)/boot/grub/grub.cfg) configfile (Load a GRUB 2 configuration file such as grub.cfg; configfile (hd0,5)/boot/grub/grub.cfg.) initrd (Loads the initrd.img, necessary for booting; initrd (hd0,5)/initrd.img.) insmod (Loads a module; insmod (hd0,5)/boot/grub/normal.mod, or insmod normal.) linux (Loads the kernel; insmod /vmlinuz root=(hd0,5) ro.) loop (Mount a file as a device; loopback loop (hd0,2)/iso/my.iso.) ls (lists the contents of a partition/folder; ls, ls /boot/grub, ls (hd0,5)/, ls (hd0,5)/boot.) lsmod (List loaded modules.) normal (Act
