need help with ubuntu dual boot

Asked by Jesse McCombs on 2010-11-16

I've been trying quite hard lately to figure out how to dual boot windows 7 and ubuntu 10.10 but i'm having some difficulties with the partitions. I noticed someone else had the same problem with their new HP laptop which is the same manufacturer as mine and they said that HP laptops use all 4 of their partitions. I noticed that i has the same problem and that i can't install ubuntu without some serious help. unfortunately that other post didnt have much information on this solution. please help.

You have to be very, very , very careful. We installed a similar system using the manual partition feature in 10 10 partition manager. You may have to shrink the existing partition (see Windows instructions). After shrinking you can use the new, available space to add a partition for Ubuntu. You then have to put in the ext4 and swap space individually. the Ubuntu partition manage is pretty good about warning you that you are about to do something critical and irreversible.
CARE is the key work.

Could you boot on Ubuntu CD, "Try without install".
In a terminal (Applications->Accessories->Terminal), type the following command:
   sudo parted -l
where "-l" is lowercase "L". This will display list of partition.
Please post result so I can check you have four primary partitions.
If this is the case, you will have:
   1) Don't hibernate Windows
   2) Shrinks/move partitions to free space for Ubuntu (
          boot on Ubuntu CD, "Try without install"
          System->Administration->Gparted
   3) Copy with Gparted one partition on an external drive
   4) Delete this partition
   5) Make an extended partition
   6) Copy back moved partition
   7) Install Ubuntu

All this is dangerous, so ask questions if you need before doing anything

Can you help with this problem?
