I have a win7 installed. For Ubuntu, I shrink my hard disk and free 80G for Ubuntu installation.

Then I installed Ubuntu alongside win7 using the free 60G space, and leave another 20G free unallocated.

After installation. I want to allocate the 20G to Ubuntu. How can I do it?

Following is my system information:

Device Boot      Start         End      Blocks   Id  System
    /dev/sda1              63       80324       40131   de  Dell Utility
    Partition 1 does not start on physical sector boundary.
    /dev/sda2   *       81920    25563135    12740608    7  HPFS/NTFS/exFAT
    /dev/sda3        25563136   513466367   243951616    7  HPFS/NTFS/exFAT
    /dev/sda4       513468414   930506751   208519169    f  W95 Ext'd (LBA)
    Partition 4 does not start on physical sector boundary.
    /dev/sda5       513468416   812931071   149731328    7  HPFS/NTFS/exFAT
    /dev/sda6       812933120   813322239      194560   83  Linux
    /dev/sda7       813324288   852383743    19529728   83  Linux
    /dev/sda8       852385792   891445247    19529728   83  Linux
    /dev/sda9       891447296   930506751    19529728   83  Linux

The 20G free space is after /dev/sda9. How can I add 20G to sda4 extended.

  • How are you trying to partition it and where are you partitioning it from: Windows or Ubuntu?

First, BACKUP YOUR DATA. I really, really mean that.

Since partitions have to be contiguous, you'll have to move the free space to either end of sda4 (did you really mean sda4, the Win 95 partition?

Boot from a Live CD containing gparted, and run gparted. Do NOT try to boot from disk and run gparted on the same disk.

Use gparted to move partition sda9 up 20GB (to the end of the free space). This will put your 20GB free space between sda8 and sda9.

Repeat moving sda8, then sda7, then sda6, and finallysda5 up 20GB. This will put the free 20GB between sda4 and sda5.

Using gparted, extend sda4 to include the 20GB.

Now, all that's left is to inform Windows that it's disk has grown. I don't know how to do that, and this is the wrong place to ask.

Having the disk partitioned the way you do is sub-optimal. Read partitioning How-Tos, etc. at the Linux Documentation Project, at IBM Developer Works, at ccfl.edu, and at LinuxQuestions.

The 'good' way (IMHO) to partition a disk is to have a few, not too big, partitions at the beginning of the disk (/boot, swap, foreign Operating Systems), then an "Extended" partition covering the rest of the disk, with the rest of the partitions allocated within it.

BACKUP YOUR DATA!
