    Hello,

    I am completely new to Linux and CentOS. Could you explain why my USB keyboard gets disabled at step 2? I cannot complete the CentOS installation because of that.

    Thank you for your help.

    hello Ravi,
    i’m having trouble installing CEntOS 6.3. i have just enrolled for the course of LINUX , and as our instructor guided, we didn’t have to go for configuring network and at ‘step 13’ we chose ‘Create Custom Layout’, then after clicking on ‘Next’ tab the window appears with following data

    sda1 (ntfs) 100MB
    sda2 (ntfs) 102410MB
    sda3 (ntfs) 204809MB
    sda4 (ntfs) 100616MB
    Free 69002MB

    I select ‘Free’ in this step , then click ‘Create’ tab.

    A window named ‘Standard Partition’ appears and then again click on ‘Create’ tab

    Then the ‘Add Partition’ window arrives, there I select as below for the first selection:

    Mount Type : /
    File System Type : ext4
    Allowable Drives : (The name of my HDD with its size showing as sda with check marked but disabled)
    Size(MB) : 40000

    after this when i click OK the error msg appears saying ‘Could not allocate requested partitions: not enough free space on disks’. why this error msg appears ? when we tried to install in our classroom pc there was no such trouble.

    my default OS is Windows 7 Professional 64-bit

    FROM DISK MANAGEMENT DATA

    (C) Healthy (Primary ….) 65.06GB free of Capacity 100.01GB

    (D) Healthy (Primary ) 25.17GB free of Capacity 200.01GB

    (E) Healthy (Primary ) 34.11GB free of Capacity 98.26GB

    (System Reserved) Healthy (Primary ) 33MB free of Capacity 100MB

    Unallocated __________________________________________________________ 67.38GB

    do i have to increase the unallocated space ? 67.38GB is not enough for CEntOS 6.3 ?

    • Ravi Saive says:

      @yasmeen,
      Please follow below instructions. First create /boot partition with size 300MB and then create swap partition as partition type Swap and then create / Partition and allocate all size..it will work..
