Dualboot ubuntu-arch

after i've installed yesterday arch linux i can't login into my ubuntu that i've mounted in other partition, because when i choose to run ubuntu from grub it gives me "error 15: file not found", here there's my menu.lst, anybody can tell me how can i do to make ubuntu work?

  • Partitioning Hard drive ubuntu arch dual boot

    Hello I am running on Ubuntu 11.10, and I'd like to try out Arch Linux. I'm pretty much a complete beginner, and would like to know exactly how to manually configure my hard disc partitions to allow for a ubuntu/arch dual boot.
    I have read the beginner's guide and have tried searching for existing documentation on how to configure the partitions. I have not been able to find anything helpful and I apologise if there are already clear instructions aimed at beginners floating around. In this case, could someone point out this documentation to me?
    Thank you

    Hi there and welcome to arch.
    First off, Google offers a plethora of information as to how to go about it.
    Our wiki has also quite a few hints.
    Just have a browse around. There's plenty of info out there.

  • Dualboot XP/Arch 0.7.2 on T60

    Hey!
    Im a newbie to linux and i heard that Arch is a i686-optimized Linux distribution so i think it sounds intresting!
    I wanna have a dualboot system with XP and Arch on a 60Gb disk. I have allocated 10Gb for XP, how much space should Arch have? (i want a separate partition where i can have some movies and music on, not on XP or Arch.) Can you help me to setup my partitions? Does Arch installation include Bootloader? if not how do i install a bootloader?
    Other questions:
    - Does my ipw3945 work fine with Arch? and is it easy to work with my Netgear 614WGRv6 router? (http://wiki.archlinux.org/index.php/Wir … up#ipw3945)
    - Does my ATI x1300 work fine on Arch?
    - Any other things i should think about before i install Arch?
    A lot of questions to you folks but i will give you alot och thanks for helping me with this!

    I left Arch and instead i installed Ubuntu... sorry guys but Arch was difficult in some steps in the installation:
    - set root password (where?? in the installation i newer saw the /etc/locale.gen..)
    - config the network (i have a NetGearWGR614v6 router who gives me dynamic IP and i want a wireless connection to the router)
    - When i tryed to installed the bootloader got error (i tryed installing on every partition i had) I had Mandriva Lilo bootloader installed on one of my Linux partitions (maybe on XP partition?) since i had Mandriva

  • [SOLVED] (U)EFI dualboot Win7 Arch Linux - partitions gone - recovery?

    Hi everybody,
    I have a slight problem with my (U)EFI dualboot system (Windows 7 and Arch Linux) which used to be configured using rEFInd like it is described in my previous post:
    https://bbs.archlinux.org/viewtopic.php … 6#p1300356
    <EFI PARTITION> is /dev/sda1 and I used to boot via <EFI PARTITION>\EFI\Boot\Bootx64.efi which then successfully either loaded Windows or Linux kernel.
    Thanks to my own stupidity and a recent update of refind I decided to copy the new driver, font and icon folders to the <EFI PARTITION> in order to be up-to-date.
    After doing so, the rEFInd boot menu had a third icon which said "Boot via \EFI\Boot\Bootx64.efi" and if I clicked on it a second rEFInd boot menu appeared with only the two icons for Windows 7 and Arch.
    So I figured I could delete Bootx64.efi and ultimately did so, unfortunately. Afterwards I couldn't boot neither Windows nor Linux anymore.
    Following this I went through my noumerous USB boot sticks in order to be able to recover the Bootx64.efi. Unfortunately the first USB stick was a Windows XP one which has the plop bootloader alongside:
    http://www.plop.at/en/bootmanager/thebootmanager.html
    Out of couriousity I entered this bootloader and found HDA and HDB (I assume resembling my SSD and my USB stick).
    To my knowledge I didn't change anything but after entering the bootloader again I just found HDA left, HDB seemed to be gone. But I didn't think of anything bad happening yet.
    Then I found a working Archiso which I booted and using blkid I couldn't find the partitions of my earlier system anymore, only its device and the USB stick:
    /dev/sda: PTUUID="..." PTTYPE="gpt"
    /dev/sdb1: UUID="..." LABEL="ARCH_201312" TYPE="..." and so on
    /dev/sdb2: SEC_TYPE="msdos" and so on
    Even within the EFI shell I could not detect any internal drive anymore (only fs0: which is the USB stick)
    Using Archiso onboard tool testdisk I could find the old partitions. The correct result of the GPT from testdisk is:

    Issue resolved If you care to know how, read on:
    Looking at the disk using gdisk was doing no good. Neither of the recovery options in gdisk did the trick.
    I then returned to testdisk and restored the partitions (successfully). However, afterwards I was greeted by shell telling me the root device was not found (seems like UUIDs get changed when one restores them using testdisk). Adjusting the PARTUUID for root in <EFI SYSTEM PARTIITION>/boot/refind_linux.conf did the trick and I could boot up Archlinux again.
    Windows 7 still didn't boot telling me the required device was inaccessible (probably wrong UUID, too). I could however not restore/edit Windows' BCD using bcdedit, see my post Status: 0xc0000225 boot selection failed; required device inaccessible:
    To make a long story short: Removing bcd and running autorecovery from withing Windows RE successfully created a new bcd. Unfortunately, Windows writes its backup bootloader at <EFI SYSTEM PARTITION>/boot/EFI/Boot/bootx64.efi. This file originally was a copy of refind_x64.efi which I need to put at that location to be able to dualboot. After chrooting to my Arch system I could restore bootx64.efi, create a new fstab and everything is running fine now again.
    Best regards and thanks for the help.

  • (SOLVED) Dualboot Windows + Arch Linux (Windows boot partition)

    Hi,
    I have 4 partitions.
    sda1: Windows boot partition (ntfs) - This has always been there
    sda2: Windows Installation
    sda3: HP_Tools - I need to keep this for warranty
    sda4: Arch Installation
    I want to use GRUB to have a dualboot option at startup. Do I need to install GRUB to the boot partition which is NTFS, this should be ext3 according to the tutorial.
    Or can I just install grub on the Arch installation in the /boot folder?
    Thanks already!

    Then you didn't install grub to the MBR. Don't forget, installing the package isn't enough, you actually have to install grub to sda as a separate step.
    So
    # grub-install --target=i386-pc --recheck /dev/sda
    # cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo
    and then

  • Belkin Wireless G USB (Ubuntu & Arch)

    I recently resized my HD and installed Ubuntu because I couldent get my wireless working in Arch. Heres my problem.
    In Ubuntu I would insert my CD that came with my dongle and run:
    # ndiswrapper -i *.inf
    # ndiswrapper -l
    rt73 : driver installed
            device (050D:705A) present (alternate driver: rt73usb)
    # modprobe ndiswrapper
    # iwconfig wlan0
    # ndiswrapper -m
    # apt-get install rt2500
    After these steps, wireless worked perfect. wlan0 showed up in ifconfig!
    In Arch I would insert my CD that came with my dongle and run:
    # ndiswrapper -i *.inf
    # ndiswrapper -l
    rt2500 : driver installed
            device (050D:705A) present why rt2500 and not rt73, and no rt2500usb?
    # modprobe ndiswrapper
    # iwconfig wlan0
    # ndiswrapper -m
    # pacman -S rt2500
    After these steps, wireless did not work at all. wlan0 did not show up in ifconfig.
    Is there something I am doing wrong?

  • Recommended partition layout for Ubuntu/Arch dual boot?

    I just got a new (old) laptop, and my plan is to dual-boot Arch and Xubuntu. The Xubuntu is mostly to hold me over so I have a stable system while I'm setting Arch up/if I mess up Arch somehow/for testing. It has a new 160GB (149.05 GiB) drive, and my plan is to allocate roughly 35 GiB each for the Xubuntu and Arch / partitions, and a roughly 80 GiB partition for common data (that is, most of my home directory folders will be symlinks to that partition - e.g. ~/code will link to /common/code*).
    Right now, my plan is to have three logical partitions - one for Xubuntu, one for Arch, and one that contains the common and swap partitions. So, I'm asking (A) are there any better ideas for partitioning, (B) does Arch still need a /boot partition, and (C) how should I handle the bootloader situation? (i.e. should I install Xubuntu's to the MBR and have it chainload to Arch's on a separate partition, or what?)
    *The reason I'm not using a common /home partition is because my config files and the like will probably be different between the two OSes.

    A) Probably -- partitioning is always a relative subject
    B) no...and it never did
    C) Whatever you prefer.
    Basic tips :
    Having a separate /home helps in re-installing(if you ever have to) and it saves your config files.
    Having a separate /var allows you to put a different filesystem on it which may be more suitable to the type of files in /var
    You can use a separate /boot, if you are going to use the same /boot for both Xubuntu and Arch. That way 1 partition handles both. If not, I think there is no need to create a separate partition. If you do create one and plan to use it for Xubuntu and Arch, make sure that you install a filesystem that is acceptable to both distros. For eg. Arch grub is patched so it can read from ext4. I do not know if Xubuntu's grub is patched or not.

  • [SOLVED] Dualboot w7 + Arch ( where to install grub )

    Hello,
    I have win 7 already installed,
    now i want to install Archlinux on same disk, but on other partitions.
    My currently partiotion schema ( MBR ) looks like:
    /dev/sda1 win7
    /dev/sda2 reserverd for linux boot part
    /dev/sda3 reserverd for linux root
    I readed beginners guide, and the only one thing is not clear for me,
    beginners guide advises not to install grub on any partiorion only on disk's mbr /dev/sda
    I can not do that, because it will destroy my win7's mbr( partion table and so on )
    Earlier with this configuration i had sabayon linux installed,
    with grub on /dev/sda2, both systems booted with bcdedit and all worked fine.
    How can I solve this ( grub2 can not be installed in /dev/sdaX )
    Thanks for any help.

    I do not know, I felt it so, earlier linux experiences, maybe better I should write "I suppose".
    It is not a question of knowing grub. It is a question of knowing Arch. When pacman updates grub, it does not reinstall to disk, it does not generate a new configuration file and it does not, therefore, touch either the MBR or the BIOS boot partition or any installation to a partition or anything else. The most pacman will do is remind you to do these things, as necessary. And sometimes it does not even do that.
    This is why, for example, it is possible to maintain grub.cfg manually in Arch but not in most other distros. Because the system will never, ever run grub-mkconfig unless you tell it to. So a manually maintained configuration file will never be overwritten unless you overwrite it.
    The only boot manager/loader I know of where this is not the case is gummiboot and IMNSHO, that makes the gummiboot package a badly behaved one which fails to properly respect the local customs. (And I won't install gummiboot for essentially this reason.)
    That said, installing grub to a partition is not recommended because it is very easily broken. So I don't think you should do that. I'm just saying that if you did do it, no pacman upgrade would ever write to the MBR. Nor, for that matter, would it update the installation on the partition. It would do zilch to upgrade the actual installation of the boot loader - it would just update the package files in your system.

  • Dual boot with Ubuntu?

    I've got Ubuntu 11.04 setup ok now on an EEE 1201N.
    I plan on dualbooting with Arch.
    What I've found out so far:
    - I can skip the installation of Grub during the Arch install, because I can modify the existing Grub config, to also include Arch in the boot menu
    - I need only one SWAP partition, it can be used by both OS'ses
    Questions:
    - Is it wise to share (use the existing Ubuntu) /HOME partition in Ubuntu and Arch? Or is it better to mount a separate /DATA partition for sharing data used in both OS'ses (movies, pics, docs, ect.)
    - Do I need a seperate /BOOT partition for Arch?
    - Any other tips ?
    Thanks for the help!

    I have a quintuple boot system with Arch + Ubuntu + Debian Sid + Slackware + Gentoo, and here's what I do:
    I create a separate data partition, different from /home, since I do not like mixing config files with my own files. In the event of a reformat, I just back up what I need to (very few rc files). This lets me have different /home's, but with the same username and not replicating data.
    I have the same swap partition for each distro.
    I use Ubuntu's grub2 alone (it was the first distro on the machine), which flawlessly detects all other distros (at the moment I have a minor bug with duplicate entries, but that is okay).
    My partitioning scheme is as follows:
    [manjul@chaar ~]$ sudo fdisk -l
    Password:
    Disk /dev/sda: 320.1 GB, 320072933376 bytes
    255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes

    /dev/sda9 457365504 499308543 20971520 83 Linux
    Partition table entries are not in disk order
    /dev/sda2 is Ubuntu's boot partition (128 MB), /dev/sda3 is Ubuntu, /dev/sda1 is an extended partition containing the following:
    /dev/sda5 is the shared swap
    /dev/sda6 is the data partition
    /dev/sda7 is Debian Sid
    /dev/sda8 is Slackware
    /dev/sda9 is Gentoo
    and I have never had an issue! I even share the Dropbox folder between all distros, and I have never had a problem. All the distro partitions are 20GB each.

  • Why gcc compile so slow on Arch?

    That's a big project, it takes about 30 mins compile by "make -j4" on Ubuntu.
    Compare to Ubuntu, Arch take more 20 mins compile time!
    The only different thing is Arch installed in SSD (project code too), Ubuntu in traditional disk.
    Due to the project can't compile with 64bit system, Arch and Ubuntu all is 32bit OS.
    The Arch already installed PAE kernel from AUR.
    Anyone can help? Thanks in advance and sorry for my bad English.

    On Arch, are you compiling using 'make -j4' or are you using makepkg and a PKGBUILD?
    I'm quit sure using 'make -j4' both on Ubuntu and Arch, and of course the same computer.
    I'm not using makepkg because we don't support yet currently .
    I've tried several times to compare build time, not occasionally.
    The project's build system is CMake, I don't think cmake is the problem.

    I'm having this same problem, but the machine locks up for no less than 10 hours (I let it set all night). At the startup screen, it still shows "Starting udevd..." and remains there. I tried looking at the logs, but nothing gives any sort of indication of what is causing it to hang up forever. I don't have a Realtek (dmesg shows Intel(R) PRO/1000 Network Driver - 1.5.1-k). As I'm still struggling with Linux at such a low level, it would probably be best to wait for the fix.
    BTW, Thank you to the developers, tech support, helpers, etc. etc. for Arch Linux and all their hard work/support, without which I would be totally lost and wandering aimlessly through a barren desert with a canteen full of sand and no direction in which to go and have no real meaning or purpose in life (a.k.a. using Windows).

  • Fight BufferBloat by testing fq_codel by default in Arch

    hi,
    As suggested  by Dave Taht in here , there is a "chicken/egg" problem in the development of fq_codel as a replacement of pfifo_fast.
    Basically it needs to be enabled as default in the wild to collect enough data for all kinds of scenarios.  Dave is trying to put a simple "debloat" script in Ubuntu, Arch and others.  So i decided to put the default enablement of his script in discussion.

  • Partitioning Questions (Measure twice, cut once.)

    I'm currently reinstalling the OS on my computer after swapping out most of the parts. It was an XP gaming machine but I plan on dualbooting with Arch as the primary OS and Windows 7 for gaming. My old XP setup had a 32GB 10k RPM HD as C: and then a number of additional HDs for program and data storage but after I get the OS set up I plan on using the 32GB for swap and temp for Arch and pagefile storage for Windows. I got a new 1TB HD as my new HDD 0 and I am currently planning on partitioning it like so.
    / (20GB ext3)
    /var (15GB ReiserFS)
    /home (Whats left ~850GB , ext3)
    /Windows (For Windows 7: 100GB NTFS)
    First a few questions for this HD.
    1. I don't plan on ever booting a second linux disto outside a VM, do I need a /boot? Should I just throw a 100MB /boot at the beginning just to be safe?
    2. Ext3 is my safe choice, I see too many people having problems with ext4 and I want data security first, and speed as a close second, but windows compatibility would be nice. I take it ext3 would be my best choice until ext4 is mature?
    3. /windows and / need to be primary, can I make the rest logical without any problems?
    4. Is the size of the / and /var big enough? The HD has plenty of space.
    Once I get the computer up and running I have to take my data off the 32GB HD and then I plan on reformatting it like so.
    Swap (10GB)
    Windows Pagefile space (Whats left ~11GB, NTFS)
    /tmp (10GB ext2)
    5. I have 4gb of RAM so I shouldn't have a big problem without swap at first, but is it easy to configure the swap and the /tmp after the initial installation is complete, is there a handy guide for this?
    6. Is how I have this HD set up even a good idea?
    Once I have all that partitioned I plan on adding the other three HDs back in, as I don't want to risk accidentally formatting them. (Wiping 2 full 500GBs and a 300GB would not make my day, plus I want to clean up my cable management when I do.)
    I have installed Debian on P3 servers, Ubuntu and Suse on laptops, and Arch on an old P2. I have also done a number of distros in a VM, including Arch a few times. I don't think I'm going to see anything I haven't seen before once I get past the partitioning, but this is my personal use computer and those before were ones that I didn't use that often so partitioning wasn't a big deal and I never got too worried about it. I do NOT want to be reformatting this computer a week later because I made a boneheaded decision, thus measure twice cut once.

    1) I suggest haveing a separate /boot. Allows for a bit more flexibility.  100 MB is plenty.  And journaling isn't much use so you can just use ext2 to save a little space.
    2) Go ahead and use ext3.
    3) Yup.
    4) Yup.
    5) Any swap partitions available will be used. No config necessary, except for /etc/fstab I guess.  Make sure /tmp is empty before mounting a new partition there (also via fstab).
    6) Sounds good.

  • [SOLVED] Trying to make Syslinux visually pleasing...

    So I setup a dualboot with Arch & Windows 8.1 using Syslinux for management. I read all through the Wiki page, set it up accordingly, and it works nicely.
    There's only one thing that really bothers me, and it's the screen resolution whilst in the boot menu. It's not like I'll quit life if I don't work this out, but It'd
    be nice to make it look nice. I used to have a UEFI-GPT scheme on my desktop and back then I used gummiboot, and, even though It lacked advanced
    configuration and personalization, it was very simple and displayed resolution correctly. It was super bare and super perfect.
    On my laptop I'm running a BIOS Legacy-MBR scheme because it came like this, I didn't change it then and it's too late to Zero it all out again.
    I'm using Syslinux now; It's just as simple and easy to use, works just as well and even supports a custom background. The only thing that annoys me
    is the 640x480 max res. It even has a hardware detection tool, I don't see how it wouldn't automatically set resolution to native screen size.
    Is there anyway to set this, or will I have to content myself with the crappy resolution? Here's my Syslinux config file...
    # Config file for Syslinux -
    # /boot/syslinux/syslinux.cfg
    # Comboot modules:
    # * menu.c32 - provides a text menu
    # * vesamenu.c32 - provides a graphical menu
    # * chain.c32 - chainload MBRs, partition boot sectors, Windows bootloaders
    # * hdt.c32 - hardware detection tool
    # * reboot.c32 - reboots the system
    # To Use: Copy the respective files from /usr/lib/syslinux to /boot/syslinux.
    # If /usr and /boot are on the same file system, symlink the files instead
    # of copying them.
    # If you do not use a menu, a 'boot:' prompt will be shown and the system
    # will boot automatically after 5 seconds.
    # Please review the wiki: https://wiki.archlinux.org/index.php/Syslinux
    # The wiki provides further configuration examples
    DEFAULT windows
    PROMPT 0 # Set to 1 if you always want to display the boot: prompt
    TIMEOUT 50
    # You can create syslinux keymaps with the keytab-lilo tool
    KBDMAP br-abnt.ktl
    # Menu Configuration
    # Either menu.c32 or vesamenu32.c32 must be copied to /boot/syslinux

    Read the wiki. You can set the resolution. https://wiki.archlinux.org/index.php/Sy … _boot_menu
    archwiiki wrote:Since Syslinux 3.84, vesamenu.c32 supports the MENU RESOLUTION $WIDTH $HEIGHT directive. To use it, insert MENU RESOLUTION 1440 900 into your config for a 1440x900 resolution. The background picture has to have exactly the right resolution, however, as Syslinux will otherwise refuse to load the menu.

  • [Solved] Non-root user cannot access mounted ntfs filesystem

    Hi -,
    i have a dualboot system (arch/xfce + win7) and i use a ntfs partition /dev/sda2 to store files i use with both operating systems. I added the partition to fstab and it gets mounted, but i cannot access it with my non-root user. With root it works fine...
    My fstab:
    # cat /etc/fstab
    # /etc/fstab: static file system information
    # <file system> <dir> <type> <options> <dump> <pass>
    tmpfs /tmp tmpfs nodev,nosuid 0 0
    LABEL=home /home ext4 defaults 0 1
    LABEL=root / ext4 defaults 0 1
    LABEL=swap swap swap defaults 0 0
    /dev/sda2 /media/sda2 ntfs defaults 0 2
    Is there any option that allows all users to use the mounted device? Or how is this usually done ...

    See: NTFS-3G for important setup information.
    My fstab line looks like:
    /dev/sdb1 /media/Win_USB ntfs-3g uid=1000,gid=users,fmask=113,dmask=0022 0 0
    This sets up some important parameters which the NTFS-3G Wiki Page covers.  Basically, "ntfs" is only a basic driver and is built into the kernel.  "ntfs-3g" is a much better, and less disk-eating, driver that you should install and use if you need the drive in Linux any more than occasionally.  My fstab line makes my user (1000) the owner and the masks lets me write and etc to it.  When you install NTFS-3G it is automatically used when you use the mount command to mount NTFS drives.  In fstab, as above, you would specify it explicitly.
    You can find your own user number by entering "id" at a terminal.

Maybe you are looking for
