I recently installed windows 7 and of course it got rid of grub2 for me. I tried restoring it but when I try to mount the ubuntu partition (sda3, extended filesystem) I get the error "mount: you must specify the filesystem type"

I get the error - 'You must specify the filesystem type'.I used the syntax on the GRUB2 page:mount /dev/sdb3 /mnt but it returns the above error.Is there additional parameters to the code???

Unitl yesterday I have a pc with ubuntu server and desktop. Server I installed first. Desktop later. But I want to remove that server and use the space for other stuff..I mess with Disk Utilities and gParted and remove the ubuntu server partition. But now my grub2 stops working. How can I restore grub2 on the desktop partition and use the unallocated space for desktop without loosing any of my stuff? I have a scanner, webserver running, samba and other apps up and running on desktop.I can boot via live cd, and I get this on sudo fdisk -l:sudo fdisk -l

My friend recently re-installed WinXP on his laptop, but I'm having trouble getting Grub2 working. I followed a guide online, but when I booted it back up again, I got a Grub prompt instead of a boot menu.

so i've just installed Burg loader in a PC which dual-booted Windows 7 and Ubuntu 11.04 with no problem using grub2 in the past. But after i installed burg it just boots up straight into the Windows OS and Ubuntu is nowhere to be found. Is there a way to restore grub2 preferably without having to lose any files?

I tried various suggestions from various online articles (most of them for ubuntu), but I couldn't find a solution. Is there any solution, specifically for Debian? GRUB reinstallation from install cd, didn't worked as well. Since I couldn't boot at all, I restored GRUB1 and I'm posting from Lenny, but I can't access Squeeze this way (probably because I have squeeze's partition, ext4 formatted).

so now that I believe I've successfully mounted the partition how do I direct the bootloader to this partition /dev/sda6 on /media/11076e45-e27d-470b-bb6d-6894f7809a0c type ext4 (rw,nosuid,nodev,uhelper=devkit)
I was attempting to format a flash drive, and well, used the wrong sdX device. I've run DiskInternals Partition Recovery tool, and all my files are still there (you have to pay $139 to have it restore the files). Is there any way using tools in linux to restore the ntfs partition/files? It was a single disk with the partition taking the entire drive. I've tried mounting it with the -t option, but it says invalid ntfs signature. Man, two lessons the hard way, make sure you backup (duh) and be careful what you type as root.
View 8 Replies View RelatedI've just bought a HP mini compaq laptop. The laptop doesn't have any CD/DVD "reader". So i was forced to download the .iso file to install ubuntu in addition to Windows XP that was present when i bought it. To do so i used UNetbootin, and i used my only hard disk as a live CD. But when i wanted to install ubuntu, they told me to create a partition. The problem is that i can't. I have only one partition sda1(nfst) which covers the whole stockage memory, and an empty space(8Mo). I can't acceed to any of the resizing or modifying options to edit the nfst partition. The only options are manage flags and umount. When i click on this one, they tell me : # umount /cdrom : cdrom is busy.
View 3 Replies View RelatedI tried searching for this both in the forums and on google but it seems that everything goes back to MBR installation. I know that "grub-install /dev/sda1" should install it to the sda1 partition, but instead of installing it keeps giving me the following error:
Code:
grub-probe: error: cannot find a device for /boot/grub.
No path or device is specified.
Try ``grub-probe --help'' for more information.
Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.
I tried this with a fresh installation of Karmic on both of my PCs. I tried with --recheck option as well, same error. Installing it to MBR works fine, but I don't want it there, have another bootloader chainloading grub. Every single guide I found installs GRUB2 to MBR, and some briefly reference to "grub-install /dev/sdaX" without going into any detail. At first I thought the problem was because Ubuntu was installed on a logical partition, so I created a separate /boot partition and formatted it as ext2, still getting the same problem.
After installing another OS on second drive, UUID for swap on my main system was missing. In other words there is no appropriate symlink in /dev/disk/. I've tried to create it manually, but it dissappears again after rebooting. Temporarily i solved this problem by adding in /etc/fstab direct address to swap device. The question is how to restore UUID for swap partition correctly?
Code:
sudo blkid /dev/sda6
/dev/sda6: TYPE="swap"
/dev/sda6 is swap partition.
Also i've tried to use tune2fs:

I got swap space full error and the ubuntu version of "blue screen of death". I used Disk Utilities to delete a 2.1GB unused partition. When I tried to create a swap space partition (with Disk Utilities) it failed. In the mean time ubuntu did some security updates. When I tried to create again Disk Uilities did not complain but only created a small ~ 500 kB partition. I deleted that and reboot and got "unknown filesystem grub rescue>". I booted from a USB key successfully. Now Disk Utilities and File Browser can see all the partitions and files on the hard drive, but GParted thinks the entire hard drive is unallocated. I vaguely remember that there are two partition table on the hard drive. It may be that one of them was deleted (when I removed the ~ 500 kB partition with Disk Utilities earlier maybe?). It seems at least the other partition table is still intact since Disk Utilities and File Browser can still see all the partitions and files. Is it possible to restore the deleted or damaged partition table and make the hard drive bootable again?

View 4 Replies View Relatedmy /dev/sdb was a truecrypt partition that was mounted when I accidentally deleted the partition in gparted (instead of sdc, stupid). I'm pretty sure I haven't overwritten anything since then, but I'm not sure how to go about recovering this one. To confound the problem, the only way I can install stuff to my ubunut machine is by downloading on a windows machine and transferring by memory stick.

Ive installed ubuntu for the first time today, i have a hdd of 500gb, that had 65gb occupied with music, movies and games.
What i did during installation:
it asked me where to install it, so i created a new partition of 100gb ext4 type, to install it there, and i was going to leave the rest for the data, but it wont let me do it, so i went back and selected the "exchange type swap linux 0x82 type" for the 400gb partition.
Then installed it, and now i cant find my data, and i have only 100gb of space in the hd, if i use the "disc utility" i can see the other 400gb, and change partition type, but i dont want to lose my data..
what I did was: - have NTFS (450GB + 4GB linux-swap + 44GB ext3 with ubuntu 10.10 upgraded from ubuntu 10.4). Ntfs partition contains data only, no windows.
- either with partition magic or paragon I tried to resize the NTFS and since then parted doesn't like my partitions anymore, but Ubuntu boots and works just fine..
- I took the output from fdisk -l and decided to remove the swap partition - ubuntu won't boot saying it needs the swap (although it was never mounted and i deleted the swap while ubuntu was active)
I have the following output from fdisk -l:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
[Code].....
**NOTE: Since the partitions are not on cylinder boundaries, using parted to recreate the partition table may not be good enough.. I don't have a backup of the partition table.
I recently did a clean install of 11.04 Beta, and I must have done something wrong with the mount points during installation, which resulted in me having a different home folder mount point or something. The old partition on which I have my home folder needed to be mounted manually. I did that once, and then upon reboot, I couldn't access the partition anymore. Disk Utility now shows the partition as "unknown filesystem".
The output of fdisk is as follows (if that helps at all):
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

On a side note, I tried using TestDisk to restore the partition, but I only created a DD image of the damaged partition, but now I'm stuck, as I'm not sure how to mount it, or if it's possible to retrieve files if I succeed in mounting the image.
I have installed 9.10 to an existing Vista machine. Here is the fdisk

I tried to install Ubuntu next to XP. After restart - no XP and no Ubuntu. Something wrong with loader I guess, I see command line prompt (of the loader I guess).
So I restarted from liveCD. But no "Repair Install" option like in XP CD. So, I deleted partition to install again on top of old, then learned a loader possibly could be fixed.
So, the problem is: testdisk cannot restore partition I deleted. I didn't write on disk anything. May be swap space after couple reloads from liveCD corrupted it?
It complains "The harddisk (...) seems to small!", it sees some other partitions and doesn't see what Gparted and Disk Utility.
Let me know the best approach to get back XP running (having Ubuntu would be good too).
Here below are the screen captures for details.
Quich Search results. Can't recover what's found. Why 4 partitions are found? Notice, "The harddisk seems too small !" Could this be a problem? HDD is not Maxtor anymore
The gap is there but no deleted partition shown
Essentially same thing... going for deeper search
Deep Search hasn't recover anything new. And shows same results as Quick Search (2nd testdisc image )Hit "continue"...
Now the partitions shown as deleted because of overlapping. The partition to be recovered is still not in the list.
Anyway, my final goal is to get WinXP back and if possible, install Ubuntu. It's nice that installer still sees the XP. Too bad the loader doesn't. how to get it done.
Unlike during installation of XP, ubuntu doesn't offer to utilize the deleted partition. Is it going to stay empty/unallocated? Forget the empty space, will I get XP running if I continue and install?
