Stories similar to grub error on installation

I have my FC11 system set up to automatically download and install updates. I had to reboot yesterday because of one of these updates. It seems that this update messed up grub. When I rebooted I only got the flickering cursor.

So far I have tried the following using the rescue disk and executing chroot /mnt/sysimage

fdisk -l gives me this result :

I have an old hard disk drive (the ribbon one) that I see using usb has a boot partition but don't see anything else.

So, I thought to try to boot up the the disk (which is running legacy grub) over usb from grub2 to check it out.

But, google has failed me.

Hi,

I have a problem in installing grub where the error thrown as " /grub/stage1 file not found" but the stage1, stage2 files are present in the /boot/grub/ folder.

I do this grub install in the final step of the Linux BMR that i have designed.

In the CentOs version above 6.0 the grub installation becomes successfull while the lower versions fails.

Kindly some one help me..

[SOLVED] GRUB / MBR problem 1 year 17 weeks ago

Hello, I'm new here but have been using #!

F12 Live CD boots and runs fine. I installed to hard drive and now get:

Grub loading. error: unknown filesystem grub rescue> _ (it is hung - I cannot type any commands here)

I think I somehow have to use root and setup but don't remember and can't find specifics

Looks like you are not using Chakra's grub to boot.If you do know that for example, it is Ubuntu's grub and it is still installed there, go to Ubuntu and at terminal, "sudo update-grub"   If you don't know, what OS is at the top of the menu?print out that grub's grub.cfg (or menu.lst)as well as fdisk -l and blkid

I foolishly installed the newest kernel update... now I can't boot anymore.

Once I rebooted, grub presented me it's friendly console.

I have the following partition structure

`/dev/loop0 squashfs

/dev/sda1 system reserved ( ntfs )

/dev/sda2 ntfs ( windows partition )

/dev/sda3 ntfs

/dev/sda5 ntfs

/dev/sda6 ext4`

I have Ubuntu installed inside windows. I formatted /dev/sda6 from inside Ubuntu ( using Gparted ). What I totally forgot was /dev/sda6 had Fedora which was the root directory of GRUB.
