View Full Version : [ubuntu] dual boot partition problems

October 23rd, 2009, 09:33 PM
I'm trying to make a dual boot Vista/Ubuntu on my new laptop. I've shrunk the main windows partition and made 106 Gb of free space for Ubuntu. \the problem is that the hard disk seems to be already partitioned into 4 partitions and Gparted wont let me make another partition in the unused space. does anyone know how i can find out what these partitions are for and which one i could safely remove without messing up windows? I can see all 4 in the disk management tool in windows, but not sure what is on them.

First of all, be extremely careful when resizing Vista partitions. Vista does not play nice with GParted...

Secondly, depending on the manufacture, one of these partitions may be for the recovery discs. Most modern laptops do not ship with the recovery discs, and you need to create them yourself. If you have already done this, you can delete that partition/use that partition.

Can you post the results from the below command while in Ubuntu live CD. This will show us how your hard drive is currently partitioned.

sudo fdisk -l

We can't tell you what the partitions are. You have the laptop. What brand and model is it? How does Vista identify the partitions? Generally, after you've made your recovery discs you can wipe the recovery partition but I'd want to make absolutely sure that was true in your case

here is the result of fdisk -l:

disk /dev/sda: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors, 48641 cylinders
units= cylinders of 16065 * 512 = 8225280 bytes
disk identifier: 0x24fa2fe4

device boot start end blocks id system
/dev/sda1 1 192 1536000 27 unknown
partition 1 does not end on cylinder boundary
/dev/sda2 * 192 32556 259969020 7 hpfs/ntfs
/dev/sda3 46413 47534 9006080 7 hpfs/ntfs
/dev/sda4 47534 48642 8899584 17 hidden hpfs/ntfs

My laptop is a toshiba, and I have created the recovery disks already.

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script 0.32 to the desktop. Once on desktop open a terminal and run this command
sudo bash ~/Desktop/boot_info_script*.sh This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

I might have missed something, I was typing out by hand because I couldn't get internet connectivity in Ubuntu last night. Here is the results again:

ubuntu@ubuntu:~$ sudo fdisk -l
