    Question Boot is too slow (more than 1 hour)

    I have windows 10 and yesterday night I installed ubuntu 16.04 LTS, but today I reboot it and it took more than one hour. This are some of the messages that appeared.

    and then appeared some messages like "(something)... Done" in green, and then ubuntu started.
    What can I do?

    I restarted again and it took half an hour to boot, but the screen was always in plain purple colour. Any help?

    And specifically what is ata2, or probably 2nd drive.
    Post this:
    sudo lshw -C Disk -short



    Did you leave in a flash drive & does it boot ok if you remove it?
    One user had a DVD and for some strange reason the system wanted to run fsck on the DVD.

    Or you may need a boot parameter to work around a hardware issue.

    I don't know what is ata2. I have a 500gb HDD, where 21 gb are in "disk 1" (I don't know what this is, but I didn't touch that), and the rest are in "disk 0". In "disk 0", I have 400 gb for windows 10 and 80 gb for ubuntu.

    I booted from a USB but know I'm booting from my HDD. There's no USB connected, and my laptop don't have any CD or DVD reader.

    I wrote sudo lshw -C Disk -short and it said USB but was replaced by SCSI and then:

    Re: Boot is too slow (more than 1 hour)

    You have an UltraBook which vendor did for a while where they added a small 16 to 32GB SSD only for Windows boot cache. Often called Intel SRT as that was the software in UEFI/BIOS.
    It is seen as a second drive, but the Intel SRT is seen as RAID and normal desktop installs do not have the RAID driver.

    Many with the smaller SSD, have used it just for Ubuntu / (root) with /home on HDD. Then all of Ubuntu is fast, where with Windows it is just used for initial boot.

    You may just need RAID driver, but not sure which one, if you do not want to turn off Intel SRT in UEFI and use AHCI only.

    First try just installing the RAID drivers.
    sudo apt-get install mdadm
    sudo apt-get install dmraid

    Change to AHCI mode in UEFI/BIOS.
    You will need to install Windows AHCI driver first.
    And then the boot cache will not work, but otherwise Windows still should work.
