While working on Fedora 20, I have faced the following error after restart:
"Error:No such Partition" Entering Rescue Mode...
I was not sure what I did. The most probable changes could be either I delete the partition during extension or may have done some mistake while setting up boot priority.
However, after googling on it, I have seen most of the solution are with LIVE CD.
Note: In my situation, the Fedora 20 was hosted in a Cloud and it was only one OS in that Virtual Machine.
Thus, I tried a different way without LIVE CD. As I couldn’t found any proper blog for the solution, so I am writing this blog which might help other System Admin also in future to get out this issue.
Solution:
- First explore the list of HD that is available on your system as :
2. You have to be sure which HD could have all your setup. So you can kindly check as I did. In my case, it is on (hd0,msdos3)
grub rescue> ls (hd0,msd0s3)/
grub rescue> ls (hd0,msd0s2)/
This steps help me to determine my HD as 3. So I am performing required action on it
grub rescue> set prefix=(hd0,msdos3)/grub2
grub rescue> set root=(hd0,msdos3)/
grub rescue> insmod normal
grub rescue> normal
BOOM !!! it will work now. Soon it restart, you will see the Linux option for choosing your OS.

tks bro
i accidentally delete the partition of ubuntu. i type above command, when i enter insmod unknown filesystem. what is the problem of my computer?
First do LS, and then when you see the list of HDD, try with each name as mentioned in above ” ls (hd0,msd0s3) ” . One of them might help you to get back.
