Total Newbie: "Error: Unknown filesystem: grub rescue"
location: ubuntuforums.com - date: April 26, 2013
First things first, this is on an Asus x401a laptop, and therefore does NOT have a disc drive. I'm currently downloading Ubuntu 13.04 on a separate computer to create into a bootable USB to perhaps resolve this one way or another.
All right, so I had Ubuntu installed on a separate partition than Windows 7, and I got everything up and running perfectly fine. It was set to go to the boot screen where I could choose Windows or Ubuntu, and if it wasn't chosen within a few seconds, it would default to Windows.
About 3 weeks to a month ago, I deleted my Ubuntu partition from the computer, and expanded my Windows partition to the original size. The laptop worked fine, and I could restart. shut down and boot up without any issue - it would always start up like it did before Ubuntu was ever installed. However, within the last week, I've been getting the "Unknown filesystem: grub rescue" error after 2 weeks+ of flawless activity. I don't know how the issue could have randomly popped

I am trying to install Windows 7 over my Ubuntu 13.04 install. I went into disk utility in Ubuntu and tried to format the hard drive to NTFS. I went to install Windows 7 but it said that it wasn't an NTFS hard drive. Now I tried going back into Ubuntu but it says "Error: unknown filesystem. grub rescue> _"
If anyone has any idea what I can do to just install Windows 7 from this point, I would be very grateful.

I'm an old guy and as much as I hate to admit it, I don't seem to be able to resolve problems when they occur any more. My laptop is a Acer Aspire 7711Z-4433 and I lost my wireless connection to my router. It came with Windows 7 and I have all of the disks.
I reinstalled Windows but I now get an error message "unknown file system. grub rescue>". I really do enjoy ubuntu but when I have these type of problems they are beyond my ability to correct them.
Can anyone tell me how to clear the afore mentioned error message or better yet how to format the hard drive. I cannot get past the error message no matter what I do. Any assistance will be much appreciated.

Hi. After replacing my entire Windows 7 OS with Ubuntu 10.04 on my Asus G73S, I've decided I want to dual-boot between the two. So I want to start from scratch and install Windows first. But after running the Windows Restore/Recovery Image (6 DVDs http://dl.dropbox.com/u/80304796/b1.jpg ), I get "Error: Unknown filesystem grub rescue" when I try to boot ( http://dl.dropbox.com/u/80304796/b3.jpg ). Any suggestions?
For what it's worth, here are my boot choices ( http://dl.dropbox.com/u/80304796/b2.jpg ) and here is what "sudo fdisk -l" returns...

There are some threads with the same subject but instructions in those threads doesn't seem to solve my case. Please help.
I've Win XP & Ubuntu 10 on my notebook. I uninstalled Ubuntu10 using wubi and removed the 30GB Ubuntu partition using a Disk Management software (one similar to Partition Magic. I can't recall the name).
While doing this, I downloaded Ubuntu 11 using Wubi. I merged the cleared Ubuntu partition with existing windows partition. Ubuntu11 (Wubi) prompted to reboot to start installation. When I rebooted, it couldn't detect GRUB and entered grub rescue mode.
My notebook doesn't have a CD ROM. So I've no way to boot using Windows XP CD or Ubuntu CD.
In the "grub rescue" command, only "ls" works. "ls" returns (hd0), (hd0,7), (hd0,6), (hd0,5), (hd0,2) and (hd0,1)

This is the message I get today. I have Windows 7/8 Mint 14 and Ubuntu 12.10 quadruple boot. I tried using supergrub 2 disk 2.00 and Rescatux SG2D 0.30.2. The best I could do was to access one of the grub.cfg files with Rescatux and get into Windows. I have all partitions backed up to external hard drive using Acronis 11 boot disk. Is there a simple way to fix grub?

i am a complete noob to linux. here is what i did.
i had windows 7 installed on my netbook. Then i installed ubuntu netbook edition. later on i wanted to try this android os for desktop. so i make a bootable pendrive the android os and try booting it from the pendrive.
in the menu i selected install it on the hard disk.
it asks me to select a partition.
i select the linux partition
then it prompts that it wont be saving any data, and it will revert back to the original after every restart as i saves all data on the ram.
so i revert my decision and go back all the way and choose to run it live.
i ran it and did not find it very useful.
so restart my pc with the pendrive ejected this time and i get the said error.
what do i do. i have some very important data on my windows partition which i CAN NOT lose.
please help thanks in advance.
p.s. i am planning to go ahead and install the android os on the linux partition on the hard drive.
is it the right move!
