What does option W? Where does it writes the partition table. I heard usage on the 80GB HDD, but where is the output file?
What setting can be wrong in BIOS? I havent changed anything there ages ago...
We have to find out why it is bad for Ubuntu, that I used the repair disc. First time when I used it, it recognised Vista as windows 7, and MBR was on the same HDD as GRUB1.99. But now the situation is different you know...

Nothing to do, the order is correct.

The f does reorder partitions if they are not in order on drive. In some cases that can cause issues where device like /dev/sda3 becomes /dev/sda2. But your partitions are in order so that command is not really even required.

You could just try the w to see if it writes. The backup you made with sfdisk would allow you to restore if it creates issues.

Partition tables are in the MBR, near the end of the MBR as boot code is in the beginning.

But everything you show looks normal, so I do not understand errors either.

Volume is corrupt. You should run chkdsk.

That's an advice... Also windows still works.

Tomorrow I will try CHKDSK again now with /f. It' really bad when you can't access to important data, and you wouldn't like to delete them...
I would like to use linux on PC, but errors everywhere. APT-GET, nVidia driver, and now GRUB and NTFS corruption...

**quailstorm** · February 5th, 2013

Using Windows XP's CHKDSK with /r option didn't help...

**quailstorm** · February 5th, 2013

Bad news. I installed partition wizard from the HDD with the damaged partition table, and it looks like it's really damaged...
What now? After two rounds of CHKDSK. Still, windows boots from the HDD...

Now what?

Issue is solved by gregrocker on sevenforums.com

Partition Wizard Partition Recovery did the work on Vista64.

**oldfred** · February 6th, 2013

It is good to know that partition wizard works.

I am still curious to what the real issue was, since some things said it was ok and others said it had issues. Gparted said it was Disk Label?

**quailstorm** · February 6th, 2013

You can see in the thread staring post that it said:

Unrecognised disk label.

There were some fake EXT3 partitions on the disk, and also some remained NTLDR and BOOTMGR boot partitions. So somehow, the kernel couldn't decide where does a partition start, because in one real partitons physical space, there could be 6-8 fake partitons too.
I never used EXT3 on the disk... But after analysing with partition magic, I got around 15 20MB large ones near each other... plus some 8MB large BOOT partitions that were correct in the past, but I've deleted or moved them.
That's why I don't use windows tools for partitioning since I burned a GParted live CD.
So partition magic deleted the fake partition entries, and fixed the three NTFS volume's data.
