This is out of my experience, but I have some thoughts:

Do not shutdown or reboot the computer until folks have a chance to respond to your query.

Please provide more information:

Were you doing this under Windows (your user agent icon says "Win7") or under a Linux distro; if a Linux distro, which distro/version?

Did you post your message from the problem computer or from a different one? On the problem computer, what is the output of

Code:

fdisk -l      <---You will likely need to run this as root

Take a look at Photorec. If worse comes to worst, it could be your last resort.

For cases of a damaged or erased partition table, testdisk is the tool of choice. Photorec is for recovering files from broken filesystems. That is not what you have. There is no reason, at this point, to believe that anything more than the partition table has been affected.

You do need to proceed carefully. You can safely allow testdisk to analyze the disk and see what it finds, but you should report those results here before allowing testdisk to write anything to the disk. If recovery does not seem to be very simple, you should make a backup image of the whole disk to another device before proceeding.

You can run testdisk from your installed system without rebooting.

Hi: & Welcome to Linux Questions.

Did you burn CD/DVD's of your Windows 7 Recovery?
If not you could call the manufacturer of your machine to get the Windows 7 recovery disc's.

From this page click on Windows and it will start your download: testdisk-7.0.win.zip

What distribution is on that gnome disk? Where did this gnome-disk come from?

-::-Unless you highlighted a partition, selected it, pressed Enter and clicked delete you may not have deleted those partitions.-::-

Sorry , i was not to able login in the forum , half of the day, be`coz I am using Tor_bundle_net, so sometimes, when I try to join LinuxQuestions I am getting an error :*( .

Code:

fdisk -l

showed that all of the my partitions is ready , exept the Swap , that i was trying to delete with gnome-disks utility . And yes it is, one of the my PC is powered on , at least 3 days in a row... ;S Be`coz i dont know , what if that gnome-disks will destroy my partition table after reebot :S .
And thanx 4 answer.

frostysh · 07-27-2015, 04:24 PM

this is logfile that I got from

Code:

fdisk -l

Code:

Device         Size Id Type
***
/dev/sda2         443,7G  f W95 Ext'd (LBA)
/dev/sda5         22,1G  7 HPFS/NTFS/exFAT
/dev/sda6            30G  7 HPFS/NTFS/exFAT
/dev/sda7           25G  b W95 FAT32
/dev/sda8           25G  b W95 FAT32
/dev/sda9        9,8G  7 HPFS/NTFS/exFAT
/dev/sda10        45,7G  7 HPFS/NTFS/exFAT
/dev/sda11        40G  7 HPFS/NTFS/exFAT
/dev/sda12        50,6G 83 Linux
***

So all of the my partitions , is in normal stage and exist!.
And that is the what i got from gnome-disks, after deleting Swap-partition
Attachment
My OS , is a Debian or something like that, jessie as I know.

And yeah , it is a nice forum place , as I see.

In this case, I must defer to rknichols. As I said, I've never had to deal with this sort of situation.

Have you run testdisk and what were the results?

You've told gnome-disks to write the partition table, and you have existed gnome-disks?

The good news is that it's done what it's done. It's written the partition table as you told it. If gparted shows your other partitions, they are still there.

I am not familiar with any Linux partition editor that will make changes on reboot. They make changes right then and there, or not at all, depending on what you've told it to do.

If you haven't quit gnome-disks yet, it hasn't written your partition table yet. It may not at all. AFAIK it would have made changes immediately. What you're seeing may well possibly be a bug (judging from nothing at all displayed in the "free space" blocks, I'm thinking maybe a display bug?).

Make a backup of your partition table (from your info, it looks as if you're using MBR), replacing (user) below with your username:

Code:

sudo dd if=/dev/sda of=/home/(user)/mbr.img bs=512 count=1

Quit gnome-disks.

Rescan, to be safe:

Code:

sudo partprobe

Check again using fdisk -l. If your partitions are still there, you're done. Don't do anything else. If they're gone, follow below.

If necessary based on fdisk output, restore the MBR backup.

Code:

sudo dd if=/home/(user)/mbr.img of=/dev/sda bs=512 count=1

Lesson learned: you say you're new to PCs, don't monkey with partitions.

Thanx to all of u , it`s SOLVED!

I used (by root)

Code:

sfdisk -d /dev/sda > ~/Documents/partition_table_backup_file_dev_sda

then , I rebooted the machine, and some sad thing happened :*( - my WinOS stops when it loading (after had been choosed in the GRUB boot-menu) , and black_screen appeared ... My /dev/sda had been transformed to /dev/sdb in Linux OS ! O_O
But it`s Amazing! After I just Installed new Linux OS to the someone partition on my /dev/sdb, i was not install a new GRUB-LOADER , and I just typed on my old Linux OS

Code:

grub-update

by root, in the terminal , so and - WinOS cans load itself after this procedure, like that`s was before! O_o

With gnome-disks, i think that was a really "bug" , be`coze it shows the empty space even when I typed

Code:

partprobe

etc.

Now i am happy to play on my favorite PC-games at the WinOS , and also enjoying the Linux enviroment ! Thanx to all , again . ^_^
