    Can't boot to Windows

    I finally got around to dual booting ubuntu 12.10 on my lenovo ideapad y580 yesterday and allocated about 350 gb to each partition (windows 8 and ubuntu). However, my windows 8 is installed in the 16 gb ssd that came with my laptop, and for some reason I'm not able to boot into it from ubuntu's boot menu. Anyone know what up? Any help would be appreciated, thanks.

    Try Bradley129's suggestion, and if that doesn't work, post back the output of

    Code:
    sudo fdisk -l

    You mention small SSD. Is this an UltraBook or Intel SRT is the standard used by all vendors for UltraBooks.

    Disable the RAID, for me it was using the Intel rapid management thingy and telling it to disable the acceleration or the use of the SSD. If you have a different system, just disable the RAID system then install Ubuntu. Once installed you can then re-enable it.
    sudo dmraid -E -r /dev/sda
    sudo dmraid -E -r /dev/sdb
    You will need to use the dmraid command prior to running the Ubuntu Installer so that it will be able to see the partitions on the drive because otherwise with the raid metadata in place it will see the drive as part of a raid set and ignore its partitions.

    No, it isn't an ultrabook. If I use the method detailed in post #9 of the last link, do I have to uninstall(?) ubuntu then reinstall it?

    Re: Can't boot to Windows

    Sorry for the late reply guys, I have terrible connection at school. Do I have to have root privileges to run sudo commands? Because they don't seem to do anything as far as I can tell.

    Edit: Sorry, I was using the wrong app on accident lol. The output of sudo fdisk -l was:

    Re: Can't boot to Windows

    Did you install Ubuntu in BIOS/CHM mode? It should be in UEFI mode?

    Boot Repair can convert a BIOS install to UEFI, since you have gpt partitioning.

    Post the link to the BootInfo report that this creates. Is part of Boot-Repair:

    You can repair many boot issues with this or 'Create BootInfo' report (Other Options) & post the link it creates, so we can see your exact configuration and diagnose advanced problems.

    Here's the link:
    Http://Paste.ubuntu.com/5593381/

    Also, I was able to boot in to Windows by going to that last option on grub and moving the order of windows boot manager up above ubuntu. But it still doesn't show up on the grub list.

    Re: Can't boot to Windows

    Usually Boot-Repair adds correct efi boot entries.
    You can manually add entries as shown as work arounds in this bug report.
    grub2's os-prober creates wrong style (BIOS) chain boot entry
    https://bugs.launchpad.net/ubuntu/+s...2/+bug/1024383
    type of entry from Boot-Repair that should work.
    'Windows UEFI loader'
    Type of entry that does not work:
    'Windows ...) (on /dev/sdXY)'

    You may have to add this for Ubuntu to see Windows as you have Intel SRT.
    sudo apt-get install mdadm

    Re: Can't boot to Windows

    Ok so I ran the recommended boot repair. Here's the log: http://paste.ubuntu.com/5594562/

    There's a bunch of windows options on grub now, but none of them work. The only way I can boot to windows is if I go to the boot section from the system settings and set the order of windows above that of ubuntu.
