http://askubuntu.com – I'm newbie here. Yesterday I decided to install Ubuntu 12.04 as I have already installed Windows 7 and want to go for dual boot. The problem is it doesn't shows me the boot menu. This is what I get: Quote: Error: no such partition grub rescue> First, I installed it manually and when I saw this message, I started searching for the solution. Tried to fix it many ways - recommended boot repair, manual GRUB2 reinstall, GRUB2 upgrade, ensured that it's in the right dev/sda drive and dev/sda7 partition (in my case), but still the error occurs... Even when I used EasyBCD, I made a Ubuntu boot entry b (HowTos)

Hello guys, I'm newbie here. Yesterday I decided to install Ubuntu 12.04 as I have already installed Windows 7 and want to go for dual boot. The problem is it doesn't shows me the boot menu.

So I resized the partition next to the one where I have ubuntu installed. Using Easeus Partition Master I made it smaller so there was unallocated space between it and the Ubuntu partition with the intention of using it to install programs. When Partition Master tried to reboot all that happened was a black screen appeared with the message ''Grub error, unknown file system...

Hi, I recently decided that I want to run a dual boot of Ubuntu 9.10 (main) and Winblows XP (games).

So I just did a clean install of windows 7 ultimate and installed ubuntu 12.10 beside it. I kept the windows bootloader in the mbr at the advice if my tutorial (i used easyBCD to enable an option for grub2) and installed grub2 to the /boot partition that I made for sda5. If it matters, I set / as sda6, /home as sda7 and swap as sda8.

I installed Ubuntu 12.04 in my computer without problems, but after rebooting i got the following error:

Error: No such partition grub rescue>

I am a novice with ubuntu and any detailed instructions to the problem will be highly appreciated.

I ran boot repair as per the following:

sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install -y boot-repair boo

After installing Ubuntu 11.10 on a pc which already has Windows 7 I get this error:

error: invalid arch independent ELF magic. grub rescue>

So I used Supergrub boot disk to get into Ubuntu. And made sure that grub-efi-amd64 package is present, and I ran sudo grub-install /dev/sda command. That also led to the same error. Then I tried the solution given here and here.

I have installed Ubuntu 12.04 64bit version. I have no problem with it until we tried to take a backup by using Acronis True Image software.

Normally, Ubuntu was seen under BIOS menu under "EFI Boot" option. Then, there was a problem with this software and Ubuntu is lost from the EFI Boot menu.

Grub Rescue: no such partition 3 years 23 weeks ago

My computer does not have a working CD rom drive, so I had booted from USB (used UNetbootin to make the USB) to install Ubuntu initially. I had Ubuntu working on my laptop (Gateway 7330gz), started messing around with it, and decided I wanted to start fresh again.

I have two partitions on my hard-didk , I have installed ubuntu on my 1st partition and windows 8 later on another partition.Now i can only boot into windows 8 because it doesn't recognize Ubuntu.

How would i dual boot my PC without using grub .
