IdeaPad Y570 - hybrid drive dual-boot ? ( Win 7 + Debian )

Hello, I've tried to find specific information but none was found so I've made this topic.
My question is. 
Is it possible to dualboot on Y570 with hybrid drive (SSD 32GB + 750GB HDD)?
I've have my Windows 7 already installed and used. I have 2 partitions - C (the biggest 690GB - Win installed + data) and D (from lenovo - drivers, utilities...) 
I haven't change any setting with partitions.
I would love to split the biggest drive C into 2 smallers - one with Win 7 another with Debian installed. 
I prefer NOT to install Win 7 again. I just want to create new partition, install Debian on it and have dual-boot system. I don't need One Key recovery system. 
Another question is, how will the SSD work with Debian? If not, I can live through that, but I would prefer if it works at least for Win 7, just like now. 
I've read that Optimus is not working under Linux. Okay, no problem, but can the external graphic card be disabled at least in Linux? 
To sum up, my goal is to have Linux without formating drive / without reinstalling Win 7. Is it even possible?
It's pretty complex question and thanks for anserws.

Is this a typo in your post or how it was in menu.lst? Surely it should be hd0,0 and not hda0,0? The entry I have in my menu.lst is as follows:
# (2) Windows
title Windows
rootnoverify (hd0,0)

chainloader +1
What was yours?

  • Dual booting win 7 and arch: cannot install grub to partition

    I have read the arch wiki page on dual booting and several other sources on line, but I am still struggling to get this to work.
    I am trying to dual boot arch and windows 7 on my lenovo ideapad s205. the machine comes with windows 7 pre-installed.
    I shrank the win 7 partition and added an extended partition with 3 logical partions for /boot, swap, and /.
    I am able to install and run arch by installing grub to the mbr. when I do this, though, I cannot boot windows. (the windows section of grub menu.lst is uncommented and points toward hda0,0. I have tried hda 0,1 as well).
    I have also tried to use the windows boot loader to load arch, as described in the arch wiki page on dual booting. The problem here is that, taking this approach, I should install grub to my /boot partition, but when I try to do this, the installer only allows me to install grub to sda or sdb (the usb stick).
    I have read that grub should be able to boot linux from a logical partition. Is this so?
    Is there something wrong with the arch installer that it is not giving me the option of installing to a partition rather than the mbr, or is this  a problem with my partition scheme, or something else?
    I am tempted to remove lenovo's recovery system, but on the other hand, I have already needed to use it several times while monkeying around with installing arch.
    Thanks for any help.
    UPDATE:
    I now have the laptop dual-booting win 7 and arch. My solution ( adapted from here: http://helms-deep.cable.nu/~rwh/blog/?p=177) was to:
    1. installed arch on the partitions I had created for it, but skipped the "install bootloader" stage.
    2. in win 7, I downloaded and installed EasyBCD and made an entry for arch in it. I checked the option to "Use EasyBCD's copy of GRUB"
    3. When I restarted, I got a grub error because the entry in grub's menu.lst was pointing at the wrong partitions for the kernel and root.
    4. So I went back into the arch live disk, mounted the boot partition and edited menu.lst.
    Now when I start the laptop, the windows boot loader starts and I can choose between win  7 and arch. when I select arch, grub4dos starts and gives me the option to start arch. this is not particularly elegant (nor is it fast), so I think this solution is less than ideal, but it does work.
    I'd be interestd in any thoughts about what went wrong and what a better solution would be.
    thanks.

  • Thinkpad x130e dual boot Win 7 and 8

    So, I bought a new Seagate SSD Hybrid drive with the intention of dual booting Windows 7 and Windows 8.  However, upon using my restore DVD's to reinstall Windows 7 on the new drive I hit a snag when trying to install Windows 8.  The Win8 intall says that the drive needs to be GPT and it is currently MBR.  So after removing the partitions and changing the drive to GPT I re-restore the Win7 OS.  Then to my dismay I find that the drive has gone back to MBR during the restore proceedure.
    Is there a way to edit the restore proceedure so that it doesn't change the drive over to an MBR drive?
    Thanks,
    Matt

    the Arch partition should take some space from the windows7_os partition. You should keep the Lenovo_Recovery partition if you don't have a Windows installation DVD, or if you think you may want to reset your hard drive to its original state someday. In my laptop I have completely removed it.
    I have a dual boot of Archlinux/Windows7, and I use the following partitioning
    /dev/sda1   ntfs   60.0GiB   /media/C (for windows os)
    /dev/sda2 (extended partition)
          /dev/sda3   swap   4.0GiB swap
          /dev/sda4   ext4    30.0GiB root
          /dev/sda5   ext4    30.0GiB home
    /dev/sda6   ntfs   376GiB   /media/D
    I use the last partition as a shared partition between Arch and Windows, for storing music and videos... I use it also for installing games, so that I  can play them either from windows or from Arch by using wine.
    I'm not saying this is the best way to do it, but this has been working for me, also I don't use a separate /boot partition, I used to have it when I had multiple Linux distros, but with Arch alone I don't find it necessary.

  • Dual Boot Win 8.1 & Win 7

    I've just taken delivery of a 15-p011na laptop.
    This has Windows 8.1 & a 1TB HDD with 5 apparent partitions seen with AOMEI Partition assistant as follows:

    I would like to create a dual boot with Windows 7 so that I can copy my Windows 7 (32 bit) drive from my old computer to another partition. I have tried shrinking the size of C partition and then installing Windows 7 32 bit on the unused partition. However, I get an error saying that the drive is GPT and I've read that the only way around this is to convert the whole drive to MBR which can be done on the fly with a utility like AOMEI Partition Assistant.
    However, MBR will only recognise up to 4 partitions and I would require 6 with the shrunk C partition so can I get rid of the 3 small partitions or will this affect the drive? I have already made a copy of the restore software onto DVD's.
    Failing that perhaps I can boot from my old Windows 7 drive as an external USB drive but any attempt to boot from it just crashes and I've tried using Paragon Adaptive resore but the USB drive isn't recognised.
    Any ideas would be greatly appreciated.
    TIA.
    Geoff.

    Given what the cable does and what device manager looks like it is a driver issue.  Their driver.  Your best bet is to contact the developer BUT I do wonder if you have tried re-installing the driver in compatibility mode for win 7
    To install in compatibility mode do the following:
    Right click the installer>properties>compatibility>choose OS

    intel i5 2520M - HD+ AG display (1600*900) - 4 gigs of ram - nvidia optimus -Hard disk 500Gigs 7200rpm - windows 7  and some other windows applications unfortunately a friend bought it for me so he bought it with alot of applications
    --the problem is that I've been using arch linux for a year now, and I love it, no experience with laptops, and I intend to keep windows because I purchased for it and I want dual boot with arch so what is the right disk partitioning to install linux and keep windows untouched............ in my old desktop it was only arch and it was like that:
    128 mb ext2 boot
    2048 swap
    50000 mb / ext4   and the rest of the disk for home folder, now with dual boot what is the right partitoning?
    the second question Does bumblebee work fine with archlinux?

  • Add'l Partitions to Dual-Boot Win 8/Arch Linux

    I'm hoping to get a dual-boot arrangement going on my refurbished Asus Q200E Netbook that Santa brought!
    Here's what the hard drive looks like now:
    Asus tells me the following:
    sda1: System Files to start
    sda2: Recovery
    sda3: OS automatically created when an OS is installed
    sda4: Operating System  [Clearly Win 8 is here]
    sda5: Unallocated space (and yet it's formatted and has 25.5 MB of data written on it)
    sda6: Add'l files for recovery
    What's the best approach to create my needed linux partitions?  Shrink sda4, and slide sda5 & sda6 to the left? 
    Any tips/suggestions/warnings would be greatly appreciated!    Does anyone know if my touchscreen will work under Arch...?
    Thanks in advance!

    I'm in the process of doing something similar (also using gparted).   Does your Asus have a touchscreen, and did it work after installing Arch? How many ext4 partitions did you use to install Arch?
    No, i don't have a touchscreen, i hope the wiki will help you with that.
    I just used 2 partitions (one for "/" and one for "/home").

  • T410: How to dual boot Win 7 with Ubuntu?

    I would like to keep my original win 7 config, but to add the option to dual boot into ubuntu 10.10 as my primary OS. Anyone had experience on how to go about doing this?
    Solved!
    Go to Solution.

    Ok, if this is what your asking; I have Win7 and I use the fingerprint reader to log into windows. I installed ubuntu using those steps listed above and it does the partition itself safely. And the fingerprint reader still works for windows. No issues. Just make sure (looking at picture 3 and 4) that you select install alongside others OS's, on picture 4 you can see a slider bar. The first section will show you your windows partition, the 2nd part is what you can move to choose how much space you want ubuntu to partition for itself. So no need to partition it your self.

  • New to Mac... I have partitioned my hard drive Dual Boot M.Lion/S. Leopard with 2 OS partitions and a Media Partition. How do I direct my file storage to the Media Partition? Can I put a "Media" folder on both OS Desktops that will allow me to drag n drop

    New to Mac... I have Partitioned my MacBookPro with Dual Boot Partitions running M.Lion and S. Leopard and a seperate media partition.
    How do I assign my storage to the MEDIA Partition once I am booted in either OS?
    Can I place a folder on my desktop so I can read/write ALL my media to?

    Why not? Make a folder in your media partition and put an alias folder (shortcut) on the desktop of each partition/ OS. You can right click on the folder in the media partition and click on "make alias".
    If you want to direct your iTunes media to point to the media partition, google "move iTunes library to external disk" and follow the steps; the instructions should be the same for a seperate partition as it is for an external drive.

  • Macbook Pro - 2 Hard Drives - Dual Boot OS OSX + Windows

    Hello guys, I've been facing an issue here
    I bought an SSD 2 years ago and changed the original MBP HD. I did a fresh install of OSX while still having my optical drive. Everything is fine with the OSX installation.
    Recently I bought an enclosure and installed the original MBP HD drive into the optical drive slot. Now i have two HD's on my MBP (Early 2011 - Unibody Model)
    The configuration for the Hard Drives is as follows:
    SSD Drive - disk 0 - OS X Running fine
    HD Drive - disk 1 - clean formatted to accommodate Windows 7 installation
    I started the BootCamp Utility formated the second hard drive to install windows from bootable USB. Everything works fine until the point where the Windows installation actually expands the files. I always get the same error, that windows cannot be installed on that drive and any changes will be reverted back to original settings.
    Several hours after researching the whole thing this is what I've got:
    The error that I am getting is for the configuration of the drives, a fix to this problem is to take out my SSD, install the old HD in its original position, install windows normally, put my SSD back in its position and put the old HD in the optical drive and thus I will have the Dual Boot of two OS in two different HD's. That's really really awful as I have to take appart again the whole thing and swap between the drives till the process is finished. This is because The EFI boot + Windows to be installed require the disk that windows to be installed to be on main slot - disk 0.
    My question here is, is there any fix to the BootCamp assistant to let me install windows on the hard drive that it is located on the disk 1 position?
    Moreover is there any way to install windows through the environment of OSX with the use of a VM, but, the windows to be a bootable OS rather than a VM bootable image? (on disk 1 - optical drive SATA port). - What I mean by that is, while running OS X normally on disk 0 run a VM software that will mimic the environment of a bootloader so that I can install windows on disk 1, but after I shut down my computer, windows should be accessible on disk 1 as a normal installed OS.
    Sorry for the long post and thank you very much for your time, any suggestions would be really helpful.

    You can install Parallels or Fusion, either will work. When you setup either Parallels or fusion you can tell it to use your already installed Boot Camp installation of Windows as its target guest operating system.
    You would then just boot into OSx, start your VM (Parallels or Fusion), then you'll have access to both OSx and Windows without having to reboot.
    I have this setup and two monitors. I have my Windows running on my external monitor and OSx running on my Macbook Pro monitor at the same time.
    Beware that you will need to re-register Windows to get a second key. This is free and easily done either online or by calling the Microsoft registration number. The reason for needing a second key is that Windows, although only installed once in your Boot Camp partition sees the virtual hardware created by your virtual machine and thinks it has been reinstalled on a new computer.

  • Dual Boot Win 8.1 & Ubuntu 14.04

    Hi,
    I would like to create a dual boot. I have a rather new ThinkPad  Yoga. Here are my questions:
    1. I was told I should make a recovery image or something when I bought it. How do I do that and what is it? is it just a plane Image or is it "Create your own Windows DVD"? In Volume Manager I have 4 Partitions, 1GB and 18GB are both called recoverypartitions, then an EFI and the normal C. (Didnt touch that)
    2.How can I get my Win Key and a proper Win8.1 Image?
    3. How can I create a new partition for installing Ubuntu 14.04 Server 64 bit? How to do it properly.
    4. Drivers for Ubuntu? Any tips?
    Thanks

    Hi,
    We may need to move this to the Linux board for the last 2 questions, but let me try to  address the Windows side.
    1. Methodology to create Recovery Media and reload a Lenovo system with Microsoft Windows 8 preload
    2. The key is embedded in the BIOS.  As I understand it, an install of the same version of WIndows should detect it automatically.  Try this for the Win image:  http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media

    Whenever I've put linux on the same disk as windows I've always used lilo to handle the booting by installing the linux bootloader to the "/root" of the linux partition, before that I would flag the partition as bootable with cfdisk while I was doing my partitioning and untoggle the boot flag for windows, this was also reversible so it never harmed my windows bootloader. 
    I would make an entry like this if I was using lilo:
    # Partition 3: Windows XP Home
        other = /dev/hda1
        label = WinXP
    and then run lilo for the change to stick.
    In grub I would imagine you would have to add something like this:
    title WindowsXP
        rootnoverify (hd0,0)
        chainloader +1
        makeactive
    I now just keep linux on its own seperate drive, to give you an idea how that works this is what my grub looked like last week, I repartitioned and only have arch on there now, so far..... , keep in mind my windows is actually on my second drive, hence the need for the "map" entries, reading up a bit on grub would be to your advantage, its hdd naming scheme is a bit confusing at first, but once ya get the hang of it you realise how powerful and usefull it can be, I love the password and fallback features.

  • Error with dual boot Win 8/OL6 R3

    Hello,
    I am hoping to discuss this with someone who has experience with this configuration. My goal is to get Oracle Linux dual booting on my windows 8 machine.
    I have installed OL but I am having trouble getting it to dual boot win8/OL using the windows boot menu. Whereas windows 8 boots as expected, the Oracle Linux option gives me the error:
    "+Windows failed to start. A recent hardware or software change might be the cause...contact you system administrator or computer manufacturer for assistance+
    +File:+ \NST\nst_linux.mbr
    +Status: 0xc000007b+
    +Info: The selected application or operating system couldn't be loaded because a required file is missing or contains errors.+"
    Here are some details of the scenario:
    - Documentation followed: Red_Hat_Enterprise_Linux-6-Installation_Guide-en-US.pdf
    - Hardware: Dell Precision M4700 64 bit UEFI
    - OEM installed/Default OS: Windows 8 Pro 64 bit
    - Installation source: OracleLinux-R6-U3-Server-x86_64-dvd.iso (written to DVD)
    These are the broad steps I followed:
    In windows 8
    I:
    - downloaded the Linux ISO software. The checksum on the download matched
    - wrote the ISO to a bootable installation disk
    - created a new 344gb partition for Linux using the DOS DISKPART command - partition 7
    Linux Install
    - I booted using the Linux installation DVD and started the installation
    - When Installing Linux partition 7 became a 500mb system partition and partition 8 became the 343 gb Linux partition
    - I manually created the boot partition as ext3 (because the pdf I was following said "+If your 64-bit x86 system uses UEFI instead of BIOS, you will need to manually create a /boot partition. This partition must have an ext3 file system. If you choose to partition automatically, your system will not boot.+"
    - I installed the boot loader on sda7. I selected “First sector of boot partition - /dev/sda7”. I assume this installs separate GRUB boot loader on the Linux partition (7) – which will then be 'chain loaded' from the windows boot menu. Put another way, it will boot with the windows boot manager, which will give me an option to chain load the Grub boot loader, which will then run Linux...
    - I chose the desktop installation
    - The installation reported that it completed successfully
    I successfully booted back into windows:
    - I used easybcd to edit the microsoft bcd and successfully created a boot menu for Oracle Linux. I used the legacy grub because the Linux documentation says "+Note that the version of GRUB in Red Hat Enterprise Linux 6 is an old and stable version now known as "GRUB Legacy" since upstream development moved to GRUB 2.3 Red Hat remains committed to maintaining the version of GRUB that we ship with Red Hat Enterprise Linux 6, just as we do with all packages that we ship.+".
    - After installing Linux and updating the BCD, the BCD now looks like this:
    Windows Boot Manager
    identifier {bootmgr}
    path \EFI\Microsoft\Boot\bootmgfw.efi

    I'm not sure the BCD entry is correct. I assume that this entry should be pointing to the nst_linux.mbr on the Linux boot partition. However I have verified that this file exists in windows 8:
    C:\NST\nst_linux.mbr
    I haven't been able to exactly confirm how the boot process should work i.e. whether this file should actually be in the Linux boot partition (as opposed to the windows c drive) and whether the BCD should also point to the Linux boot partition when referring to this partition.
    As I mentioned above, I now have the windows boot menu with Windows 8 (which boots successfully) and Oracle Linux (which gives me the error see below for complete wording**). Is the Real-mode Boot sector wrong? Should it point to the Linux boot partition? Is it a problem with my UEFI disk? I don't think it should be because this version of Oracle Linux supports UEFI and my hardware is UEFI.
    Has anyone carried out a similar win8/OL dual boot?

    Hi,
    Here are my responses:
    *[asmirnov]* Could you please confirm, I just want to see if I got it right the first time -
    *[2001]* I'm happy to share my progress
    Q1)
    *[asmirnov]* You did create a partition (where you would install Linux) from Win8, correct?
    *[2001]* Yes. I used diskmgmt.msc to create a separate partition. I didn't format the partition because the Linux install doesn't want that, it creates and formats the partitions in the unallocated partition
    Q2)
    *[asmirnov]* You use GRUB (not GRUB2)?
    *[2001]* I'm not sure where you were asking about, so I hope my answer here covers all possibilities you may have meant.
    I was using the windows 8 boot. I wanted to chain load to the boot loader in the Linux Partition. It is interesting what the Linux install did with my partition, it created 2 partitions in the unformatted partition. 1 was a bootable partition and the other was the Linux partition. The details were:
    2 sda’s (a boot / ext4 and a VolGroup (vg_linuxlocalhost)/ physical volume (LVM) ). In the VolGroup it created 3 lv’s, lv_root, lv_home and lv_swap. I understand that this is all normal.
    I followed the documentation note which said "To configure the Red Hat Enterprise Linux boot loader to chain load from a different boot loader, you must specify the boot drive manually. If you chose any of the automatic partitioning options, you must now select the Review and modify partitioning layout option before you click Next or you cannot specify the correct boot drive"
    So there was also the note in the documentation that said "Note that the version of GRUB in Red Hat Enterprise Linux 6 is an old and stable version now known as "GRUB Legacy" since upstream development moved to GRUB 2.3 Red Hat remains committed to maintaining the version of GRUB that we ship with Red Hat Enterprise Linux 6, just as we do with all packages that we ship." I didn't install any bootloaders manually (either the windows 8 OOTB default that came with my machine or the Linux one), I just took the defaults. I'm wasn't sure how to access the Linux partitions once it is installed, so I can't confirm it was the legacy GRUB in the Linux boot partition, but I believe this note is saying that it OL6 does use the legacy grub. I believe GRUB Legacy is version .97.
    Q3)
    *[asmirnov]* Which version of Linux exactly did you use, was that Oracle Linux or you used one from RedHat directly? What is the kernal version?
    *[2001]* I used "OracleLinux-R6-U3-Server-x86_64-dvd.iso.sha1sum" from the mirror site http://mirror.aarnet.edu.au/pub/oraclelinux/OL6/U3/x86_64/. According to the release notes at: https://oss.oracle.com/ol6/docs/RELEASE-NOTES-U3-en.html the kernel is
    - Unbreakable Enterprise Kernel Release 2 [kernel-uek-2.6.39-200.24.1.el6uek]. Installed and booted by default
    - Red Hat compatible Kernel [kernel-2.6.32-279.el6]. Installed by default
    Note: By default, both the Unbreakable Enterprise Kernel and the Red Hat Compatible Kernel for the specific architecture (i386 or x86_64) are installed, and the system boots the Unbreakable Enterprise Kernel by default. If needed, /etc/grub.conf and /etc/sysconfig/kernel can be modified to make the system boot with the Red Hat Compatible Kernel by default.
    Regarding your follow-up point that "Microsoft blocks 3rd party chainloaders from the BCD menu for UEFI machines. We are researching workarounds, none have presented themselves as of yet.", I'm not sure it actually blocks it, but it certainly isn't a straight forward process.
    I have actually abandoned my attempt to get the dual boot working. It is a real shame because I wanted to do it for my own satisfaction.
    I am now using Oracle Virtual Box as suggested by others, include Dude earlier in this thread. This has given me confidence that I was doing all the right things because the install worked first time without any problems. The virtualization is much simpler and I have had no problems so far.
    Fusion
    As for your point about the fusion middleware and OL5. I am looking at Oracle SOA with is part of the Fusion brand. I think that the latest SOA components will work on OL6 - but I have yet to try it. Following the certification matrix can be a little difficult. So as I indicated above, my current thoughts are to use the Oracle Virtual Box with Linux r6 u3 and to install the SOA components on that when I get chance. The alternative is using the pre-built virtual machine it has Linux and SOA (it might cover your stack too, or there may be another one that suits you better on the site) http://www.oracle.com/technetwork/middleware/soasuite/learnmore/vmsoa-172279.html. Note that this is still on OL5.
    I hope this helps.

  • G780: dual boot Win 7 and Linux

    I have a G780 with win7 pre-installed. When I tried to get GNU/Linux Mint Dual-booting, the wifi-driver didn't work and most importantly, I wasn't able to make a new partition because there were already four: the boot-partition, the windows-partition, one labeled "Lenovo" and one "Lenovo2" (or something like this). The hard-disk is formatted in a way so that only four partitions are allowed.
    Does anyone have an idea how to solve those problems?
    Moderator note:  off-topic post moved to its own thread.  Subject edited to match content.  Was:  Re: Dual booting pre-installed Windows 8 and Linux?

    Hi Zoltan.
    You'll need to operate on the partitions with gparted. It uses its own partition table type, gpt, instead of the DOS partition type, which limits the number of primary partions to four.
    I believe that Mint comes with gparted, but you can boot gparted from a live cd or usb.  With it you can shrink the Windoze partition to create root, swap and home partitions.

  • Dual Boot Win 7 & win 10 Problems?

    I am dual booting this, (Win 10 on my 2TB HDD and Win 7 on my SSD.) and now when i try to boot back to Win 7 my mouse switches off. The thing works fine in 10, and had been workign for years on 7... Anyone else seen a problem like this? 
    I have tried reinstalling the mouse drivers and it isnt helping on Win 7. Unplugging and pluggung in, the mouse lights up for a split second, but then dies again. switch back to Win 10 and it works as usual. No problem at all...

    Hi RobGamez,
    Are you using USB mouse?
    If so, how about another USB port?
    If this is a USB mouse, I suggest you uninstall the USB controller in Windows 7 system and restart to check if you can get it work.
    1.Open Device Manager.
    2.Expand Universal Serial Bus controllers.
    3.Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
    4.Restart the computer, and then reinstall the USB controllers.
