I can't make partitions.

Strange. The grub2 on the MBR is pointed to a totally different location. Boot into live mode and in terminal try:

sudo mount /dev/sda6 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

Restart and see if that helped.

[dsman]

I did it,but this doesn't help too =(
Still same problem.

I have the same problem.
I'm currently running Windows 7 64bit.
I want to dual boot Windows 7 and Ubuntu, but I cannot install Ubuntu.

Here's the details:

1. Ubuntu installation cannot detect any partitions.
2. GParted cannot detect any partitions.
---- GParted has an error "Can't have overlapping partitions."
3. fdisk -l <-- It shows my partitions

My guess is either:
there's some problem with my HDD
or Ubuntu (11.10) cannot detect HDD with many partitions (partitions with different sorts of filesystem).
I'm suspecting the latter.

And please take a look at the screenshot.
It shows what I'm saying very clearly.

dsman, how many partitions have you created in ur Windows HDD?

Is it three?

@genyue
Please do not hijack someone else's thread. It sounds like if you have overlapping partitions you have a partition table error. Almost any systems that read partition table will not work until it is fixed.
Better to post terminal output than screen shot as I cannot make out details in fdisk. Use sudo fdisk -lu and post in new thread.

[dsman]

Do I need to have istalled ubuntu for outputs from "sudo fdisk -lu"?

No, it works in live mode without installing anything. The command is included on the cd.

[dsman]

Here are my outputs from "sudo fdisk -lu".

Shrink those Windows partitions to free up space on your HD.

• Then use your Ubuntu CD as a "live OS", and use the disk partitioner that is on the CD.
  
• Alternative is to download SystemRescueDisk, and run as "live OS", use the application GParted on SysResDK.

I still can't find solution of my problem =(
