    Partitioning a dual-boot laptop with 32GB SSD. Advice requested

    Hi,

    I just bought an HP envy 6-1050ss. It's got a 500 GB disk + a 32 GB SSD. It comes with Windows 7 preinstalled (not 8, yay!), and I intend to keep it as a dual-boot, although my primary OS will be Kubuntu. I still depend on Windows for a few things. The current partitioning is as follows:

    /dev/sda1 199 MiB name:SYSTEM (bootable)
    /dev/sda2 446 GiB name:OS
    /dev/sda3 19,47 GiB name:Recovery
    /dev/sda4 108 MiB name:HP_TOOLS

    /dev/sdb1 6 GiB allocated
    /dev/sdb has 23,82 unassigned GiB.

    From what I've seen, Windows is using just 6 GiB of the SSD as a hibernation partition. The rest goes unused.
    I think I'd better not mess up with all the tools, recovery and system partitions, because I've had problems in the past moving these OEM setups; they tend to want the same things in the same place.
    On the other hand, this 32GB SSD is screaming for a more optimal use. An SSD just for hibernation????

    So, my plan right now is:
    - move the Windows hibernation file to C:\ or create a new hibernation partition on /dev/sda
    - resize /dev/sda2 and make room for Kubuntu /home
    - use /dev/sdb1 as kubuntu root.

    Now, for the questions:
    - any drawbacks to the plan?
    - how will Windows react to Grub taking up boot control?
    - can you suggest a partition plan? I intend to leave some 150 GB for Windows, and the rest will be for Ubuntu /home, /tmp, and whatever is not advised to be in SSD.
    - I have 6 GB of RAM. Do I really need to reserve 12 GB for swap?

    Thanks in advance,

    My guess is you are using MBR BIOS, not UEFI -- in which case you can NOT create any more partitions on the HDD. The four there already max out the limit.

    You could move the HP_TOOLS stuff into an existing partition and remove that -- but that is so small as to be all but useless.

    IF you plan to shrink down the Win7 OS partition to make room, be sure to use the Win7 Disk Management tool --NOT the Ubuntu installer or any Linux filesystem utility.

    IF you don't feel comfortable using the Win 7 Disk Management tool, then download the MiniTool Partition Wizard Boot CD, burn a CD from that ISO file, and boot from that. That is a full-feature Windows partitioning tool.

    Also, BEFORE you mess around with installing Ubuntu, do yourself a favor, download and install the free version of Macrium Reflect (MR), burn the MR Linux Boot CD, and image off Win7 (including the boot partition) to an external drive. That way, if anything goes wrong during the dual-boot setup, you will have a way to restore Win7.
    Ubuntu 15.04 Mate, Mint 17.1; MS Win 8.1, Win10 TP.
    Will not respond to PM requests for support -- use the forums.

    +1 on Mark Phelps suggestions.

    I have seen the Intel SRT mostly with the new UEFI systems. Is your also an UltraBook with dual video?
    The link in my signature is on UEFI systems, but also has some info on Intel SRT.
    I thought the SSD was not just hibernation but to speed up some Windows activity also. Some have installed Ubuntu to the SSD, others have installed to hard drive and re-enabled SRT.
    Intel SRT uses RAID somehow which you have to turn off.

    Since you are still BIOS you will need to delete one partition on hard drive to make a new extended partition. Most delete HP tools.

    Ubuntu on hard drive, re-enable SRT post #19 details
    http://ubuntuforums.org/showthread.php?t=2129157
    Disable the RAID, 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.

    Good point on the four partition problem. I have found this posting that gives instructions on deleting the HP_TOOLS primary partition, and then put it back as a logical partition.

    I have already shrunk the C: partition from within Windows. It didn't shrink enough on first try, so I followed this guy's suggestions.

    I'll take your advice and take the image off Win 7, just in case. The only problem is that the machine doesn't have a DVD; I'll have to get a USB DVD drive.

    I am not sure that this has Intel SRT. It's an Ultrabook (15,6" screen, but it's got an Ultrabook sticker) and it's got a discrete Radeon card.

    From some of your links, it seems that Intel SRT needs a proper partition to do its cache thing, but this one only has a 6 GB hibernation partition. Is there any way to make sure? That would be one less hurdle.

    You can image to flash drive. I now use flash drives for some backup, but still like to have a (more) permanent backup to DVD.

    Because the Intel SRT uses the RAID, the liveCD does not see the partitions correctly. I think if you install the RAID driver dmraid it may show it. Gparted did not work with RAID at all, but the very newest works with some RAID types, but you have to download the very newest gparted liveCD as that verson is not in the Ubuntu live installer yet and would not be in any of the older verisons of Ubuntu.

    Re: Partitioning a dual-boot laptop with 32GB SSD. Advice requested

    Hi,

    You can also work on different way like I do with mine notebooks and stand alone computers.

    Place your windows completely on 1 hard-disk and place your linux on the second hard-disk.

    1. First go into your BIOS, go to Tab Main and enable Boot Menu option.
    2. Just put for installation the empty HD into computer and install your favorite linux OS.
    3. After installation, you put back your Windows HD into computer together with your Linux HD.
    4. If you start computer, press the key so you can choose by bios wich HD you want to start. (for mine Acer I need to press F12)

    This is a handy way to install a second OS into your laptop...The linux installation will never affect the windows & the windows never the linux installation.
    You don't need to worry about the bootloader from linux neither the loader from windows, the bios does do the work for you. If you've a 3th HD for laptop, you just put one out, work the same way...
    So, you can always change from Operating Systems. For mine work I use Windows & ubuntu, but when I"m on holiday, I want the same notebook but with a harddisk debian and ubuntu...this is possible if you work like that.
    If you do a complete upgrade, don't be scarry..it is one notebook with complete shielded HD's if you not make references to it!

    The hard-disk you put on sata sleeve 0 will be the first started if you not interrupt the computer with F12 (for other computers this can be other F-key), so I suggest you put there the one you most use, the other OS you put then into sleeve1.

    Positive:
    1. If you have 2 - 3 - 4 -....harddisk and you work like that, then you can install on each hd an OS and you can always choose wich OS you want, if you go on travel...
    2. Don't be scare about Windows bootloader or Linux Grub loader, the Bios let you chose wich HD you want to start!
    3. If Linux crashes or windows, don't be scare it affect an other HD.

    Negative:
    1. In most notebooks you can place 2 HD, so if you want to put an other HD into it, you need to open your notebook, and replace a HD.
    2. When notebook start, you need to press the F-key so you get the BIOS bootmenu option for chose wich HD you want to start...by default he starts the one on sleeve0

    I work no already some years like this and I did configure 3 HD for mine notebook Windows7 - Ubuntu 12.04 - Debian. I can always put 2 from them into mine system...and I've also a 4th HD wich I also did install, but this is for testing things....

    Hopes mine english is good enough to explain,how I did do it!

    Re: Partitioning a dual-boot laptop with 32GB SSD. Advice requested

    I am attaching two screenshots of how Gparted 1.16.1.1 sees both disks. I see no sign of RAID, here. The warning sign on sdb (the SSD) is because Gparted doesn't recognize the partition type (hibernation).

    However, looking at the BIOS, it does say "Intel Rapid Start Technology" is <Enabled>.

    As for UEFI, the BIOS seems to suport it, but Legacy Support is enabled. According to the inline help, this mean that the BIOS will load Compatibility Support Module to support Legacy OS such as Windows 7, ... If Legacy Support is disabled, BIOS will boot in UEFI Mode without CSM to support Windows 8.

    UEFI, being disabled by default, doesn't seem to be a problem. Will RST be?

    The newest versions of Ubuntu seem to install to systems with Intel SRT(older versions did not), but often grub then still does not work with RAID with standard desktop installer. Grub sees RAID on the hard drive and does not know whether to install to a MBR or to the root of the RAID. If really standard RAID it does not install to MBR, but you need it installed to the MBR. The drmraid commands posted above to remove the RAID meta-data will let you then correctly install grub2's boot loader to the MBR.

    Be sure to boot Ubuntu in legacy mode. You should get accessiblity screen (tiny icons of person & keyboard) at very begining. If you get grub menu at startup you are in UEFI mode. It installs it the mode you boot installer.

    Re: Partitioning a dual-boot laptop with 32GB SSD. Advice requested

    After some more research, it *is* using Intel RST, with RAID and everything. This link explains the setup. The part of the SSD used for raid doesn't show as a partition, but the Intel RST driver is using it. I am attaching a screen capture of the setup: 6 GB for hibernation, 24 GB for RST.
    IntelRST.PNG

    So, after reading everybody's advice and links, let me see if I have got right. I have three options:
    • adding a new hard disk, just for Linux. Sorry, it's a new computer, and I really don't need that much disk space.
    • keep Intel RST, leave the SSD to it, and install Ubuntu in the mechanical hard drive as if the SSD didn't exist. This has a caveat, since that RAID setup may fool Grub, so I need to disable Intel RST temporarily, use the drmraid commands oldfred posted to disable RAID, install Ubuntu, and then re-enable it.
    • disable Intel RST, disable Windows hibernation (and re-enable it after installing Ubuntu), and install Ubuntu in the SSD. I'm inclined to do that. After all, the goal is having a fast computer, that's why I'm installing Ubuntu, after all.


    Whatever I do, I have to remove at least one of the four partitions that HP creates in new systems; I plan to remove the HP_TOOLS and create it back as a logical partition. Thanks for the pointers for disk image tools; I'll see if I can use them from a USB hard drive I have around.

    As for the rest: the computer is certainly booting in Legacy mode; I got the person and keyboard icon; I had to set acpi=off, by the way, but that will be another issue.

    Thanks a lot, I'll keep you posted

    If you are primarily a Windows user then I would keep the Intel SRT. But if primarily an Ubuntu user then installing / (root) to the SSD and not re-enabling SRT make make more sense.

    I typically install Ubuntu into a 25GB / on my stand alone SSD and have all data on my hard drives. But I keep /home inside / as I link all the standard folders back into /home so /home is tiny. That is a bit more advanced, so a separate /home on rotating drive is easier to configure and use for newer users.
