I've a problem with my computer(dual boot win7 and ubuntu11).
I resized the windows-system-partition and a NTFS-data-partition, with the windows-standard tool. After the next reboot the grub loader started with:
error: no such partition.
After a bit of research I tried to find the right partition with the grub directory:
(hd0) (hd0,msdos5) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)
grub rescue>ls (hd0,msdos1)
error: unknown filesystem
for all partitions that are listed with 'ls' the same respond.
something like "error: no such file" should be the correct
respond for an accessible partition.
The prefix and root is set to:
I tried to set it to any other partition but after a reboot the prefix and root is still on hd0,msdos6; but this don't exist.
Recognized grub commands are: ls/set/unset/insmod , and the prefered answer is:
error: unknown filesystem
I also tried to boot from CD. But this don't work neither with the win7 or the ubuntu CD.
So it looks like I crashed the machine.
Please help me.
When you resized your windows partition you may have corrupted your ubuntu / partition or changed the mapping. The easiest repair would be to reinstall ubuntu and make sure to select the right partitions to install. Also backup any data you want to save on the ubuntu now on your h/d.
thanks for help.
@LinuxNoobX: I'm reading about the UNetBootIn, I never needed to boot via usb-drive.
@Larry: The main problem is that no CD/DVD is recognized for booting.
All important data was saved on another drive. So it's just the annoying reinstallation.
The win7 system runs for 2 years, the system partition was full. I needed to uptdate a programm, thats why i tried to resize the partitions. win7 is a hd-space-greedy-thing, you give 30GB and it needs 31GB, you try it with 40GB and after to weeks it needs 41GB.
You notice if you look in the windows folder for win 7 after about a year of using it that there are alot of .sxs files that account for why windows 7 bloats up so much. These files also help the OS run more smoothly as well... so it's a good trade off. I am glad we were able to help Z/Z
That is not solved, that's ignored.
To be considered solved you must find a solution. All you did was put off learning.
I had a similar problem and had great hopes when, in my search, I found your "SOLVED" thread.
All you did was completely trash your install, (basically used the windows XP/macOS method of boot repair)
BTW to solve this issue, I suggest trying
Rescatux or Super Grub2 Disk http://www.supergrubdisk.org/
It takes some reading (less time than I spent on the actual search), but worked for me.
I created a rescatux bootable usb, then used the process as described on their website.
I did not have to re-install any of the 3 operating systems affected by my error.
hey thank you,
@LQ Newbie i read your thread and it was very helpful to me..but i have a doubt can i copy ubuntu from cdrom to pendrive and then install it?wil it work??
and because of this will my data in win & will b deleted?
