OS X and Linux dual boot

I have installed a new hard drive into my computer and partitioned it off. I have Mac OS 10.4.3 on 1, music on another, games on yet another... and a 10gig partition for Linux. I have all the cd's for the flavor of Linux I want... but I want to know how I would boot from one system or the other. I think "startup disk" in OS X can select Linux... but how would I select OS X from within Linux?
Rev. B Yosemite G4 500mhz Mac OS X (10.4.3)

Most Linuxes use BootX or something similar to allow switching the boot from one OS to another. Read the installation and usage instructions for the flavor you're installing. I'm sure it will be explained.
The Mac hardware also supports Open Firmware booting by holding the OPTION key down after the chime on a restart. The selected boot device is only good for the current startup. The next restart returns to the permanently set startup volume. This is a bit like BootX and may also work with the Linux partition.
Out of curiosity why install Linux when OS X provides Unix by simply booting into single-user mode (restart and hold COMMAND-S keys down.)

Mac and Linux dual boot mac G4

Ok I now have a linux os that works on my power mac G4 but now I would like to dual boot it.
Anyone know how to do that?
P.S. I'm doing research on the subject myself and If I find a solution before anyone on here can answer this I will post it.
(Hopefully)

Depends on which Linux distro you're using. The general outline is:
1. Using the OS X installer, partition the disk in two partitions, one for OS X and one for Linux. At this point the Linux partition can be the OS X Disk util's default HFS+; it's only created as a placeholder.
2. Install OS X to the partition dedicated to it.
3. Using the Linux installer, remove the partition previously created for Linux and create at least three partitions for Linux in the freed space: one for bootloader, one for the Linux OS and one for swap
4. Install linux to the partition given to it.
5. If not handled by the installer, install and configure the bootloader
6. Point Open Firmware to boot from the bootloader partition.
The bootloader partition contains the machinery for multibooting. It's usually under one megabyte, but I'd advice 16MB to better accommodate a better bootloader. Yaboot is still usually the default, but grub2, which is a bigger should become the standard at some point.
Swap should be 1G or so.

Solaris 10 and Linux dual boot

I currently have Linux installed and would like to install Solaris 10 on the same system via a different H-drive. I would like to have both OS fully functional.
I have loaded Solaris 10 CD1 but unable boot into solaris to complete installation.
I have edited linux /boot/grub/menu, syntax outlined below.
title solaris in hdc1 known to grub as (hd1,0)
root (hd1,0)
chainloader +1
Still unable to boot up solaris getting error: 21
Here's my hardware configuration
Primary Mstr: 1 ide H-drive - Linux
Primary slave: n/a
Secondary mstr: 1 ide H-drive - Solaris 10
Slave: DVD
Thanks to all in advance!

OK, folks, I have solved it and here are my last words on the subject.
First of all, my verdict is to use the Solaris GRUB to boot all the other OS's, just because the Linux GRUB "cannot mount the partition", where Solaris kernel is. The Solaris GRUB can do it all.
I can absolutely boot my Linux (hd1,0) partition from my SXDE GRUB installation on (hd0),
for that I use the following section in */boot/grub/menu.lst*:
title SuSE-10.3-GM
root (hd1,0)
kernel /boot/vmlinuz root=/dev/sdb1 vga=0x31a splash=silent ht=on showopts
initrd /boot/initrd
map (hd0) (hd1)
Yes, "*map ...*" string is important, for GRUB starts the counting from the drive it is installed in. It seems, the author of the original post is missing this string in his bootloader configuration; his Linux is on (hd0) and Solaris on (hd1), so he needs to use the "map" string.
I must also add to this, that when I booted last time into my Linux (SuSE10.3), I took care to install it's own GRUB bootloader into the Linux installation partition(must be set bootable). You have different ways of doing it, basically you can log into GRUB shell and do this:
grub> root (hd1,0) --- my linux partition
setup (hd1,0) -- the partition I wanted to install GRUB into(which IS my linux bootable partition).
This helps when you've got your first drive MBR corrupted, and need to boot your linux somehow; then you "chainload" from the boot partition.
However, the example shown above boots my SuSE right away, without chainloading into the GRUB installed into the Linux partition. Yes, Solaris GRUB does that without complain, and I added this section manually to the menu.lst when logged in after the SXDE installation was complete. My homage to the Solaris version of GRUB in this case, which is more capable, than the Linux version. Thanks to you developers!
If GRUB couldn't boot linux kernel directly, I'd have to use chainloader string (which is also known to work) like this:
root (hd1,0)
chainloader +1
map (hd0) (hd1)
And the problem I had with installation and partitioning was solved by formatting the whole drive into Solaris. In fact, there had been a lot of partition deletion/creation by me, so the Linux fdisk could see one partition configuration, while Solaris fdisk saw it all different. Well, I can see that disk partitioning in itself is a bit more complicated process, than the end-user wants to think.
Excuse me for such long letters, I just tried to give a thorough account on the matter. Hope this would help somebody out there.
Cheers,
Kostya

ATI display driver lost with Linux and XP dual boot os

I brought ThinkPad W500 with windows vista. I want to get rid of the hidden boot system reserved partition and downgrade to windows xp and install OpenSuse os. Following some sourses found on the web, I first set the bios sata ahci mode to compatable mode. Then install windows xp and update the sata driver. Restart and reset the bios sata back to ahci mode. It works fine with windows xp and I install back all driver. Finally I install OpenSuse and create dual boot with Grub.
But a serious problem come up with me. Everytime after restart from the linux os and back to windows xp, xp doesn't regonize the ATI display divice and tell me no driver installed with low screen resolution. And I have to restart the machine and boot direct into xp for the second time and the problem gone. But it is so annoying of doing this everytime. Anyone can help? Many thanks.
Solved!
Go to Solution.

Hi stanleyimko,
I don't have an answer, just a couple of questions:
Does your W500 have switchable graphics? If so, you may have to turn off "let the OS detect" or permanently select one or the other in BIOS. XP isn't switchable aware, so I don't know why that would make a difference.
Do you see the problem on cold (re) boot to XP, or only on warm reboot from Linux to XP?
Seems like something is leaving your BIOS in an odd state (I guess that's obvious) and maybe a cold reboot would sort it.

Uninstall Linux and Grub dual boot from Win7 HP dm4..

uninstall Linux and Grub dual boot from Win7 HP dm4. I only have recovery disks. I just want to do a Startup Repair not a full system recovery.
When I reboot with the recovery disk there is no choice for Startup Repair.
thank you for any help.
Blue Jacket

Hello bluecape. I understand you'd like to uninstall Grub/Linux. Is your recovery disc a Windows Recovery disc or the HP System Recovery disc?
You will need to begin by fixing the "Master Boot Record." This is where Grub is installed and what allows you to select your operating system. If you have a HP System Recovery disc the steps may be different--these steps are specifically for a Windows Recovery Disc. Try the following.
Boot the notebook with your Recovery Disc.
Select "Repair your Computer."
Select your Windows version once the dialog box populates.
Choose "Command Prompt" as your Recovery Tool.
From the command prompt type "bootrec /FixMbr" and press Enter.
Once this is finished type "exit" and press Enter.
Take the disc out and reboot the PC. It should boot straight into Windows without a boot loader prompting you.
The Linux files and partitions are still there but you can now remove those partitions from Windows. Simply format the partitions to "uninstall" Linux.
I hope this is helpful. If you have further questions just let me know. Have a great day!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"

HP CM1312MPF drivers don't work via Windows 7 but works fine via Linux dual booting

HP CM1312MPF drivers don't seem work using Windows 7 (64-bit) . Original HP drivers CD now lost. Current drivers were downloaded from HP's website. (This webpage has a number of drivers and most 64-bit ones have been tried. Prior to my Windows re-install, the machine printed and scanned satifactoralily in Windows 7. One day this O/S refused to boot and had to be fully re-installed. The reinstall has been tried on both a SSD and on a HDD. (I have 3 x HDDs and 1 x SSD in this Desktop system. and I dual boot Windows7 and Linux Mint with data on its own HDD.) No attempt has yet been made to scan after this Windows re-install, as I have a separate photo scanner. I mainly wish on the to print on CM1312MPF, however it did scan perfectly well prior to the reinstall of Windows. THE CM1312MPF PRINTS FINE VIA THE SAME USB OUTPUT LEAD (AND POWERED HUB) AS VIA LINUX MINT 17 (PETRA) when I dual boot and without any PHYSICAL CHANGES between changing O/Ss. It must be a driver problem, surely, mustn't it? I look forward to your help. John_of_Penrith

You can also disable that windows wireless "Critter" from device manager and it shouldn't ever again show-up in your adapter list. Thanks for the lesson. I too have wondered about the windows virtual adapter and what it's for. I never had it show-up in my adapters though in the network and sharing center. That was strange that it happened to you. I also occasionally just go to device manager and reload the adapter that came with laptop-not the windows one. It
seems to keep it running fairly well since there have been no new drivers for it. I think it was an experiment or something called the DW1501 Wireless half-mini n that came with my Dell Inspiron N7010 laptop. I don't particularly like it as compared to the other wireless adapters in my home, this thing is slow on downloads, but I don't want to bother to get a new adapter.
Anyhow thanks for the interesting lesson.

OS X and Arch dual-boot on MBP - bootloader error

I have a Macbook Pro 9,2, and I dual-boot OS X and Arch. My main Arch partition is encrypted with an LVM on LUKS setup, and my main OS X partition is encrypted with Firevault 2. I run the vanilla Arch kernel, and I use xfce as my DE. I use refind as my boot manager, and grub as the bootloader for the Arch partition. This setup has worked flawlessly for several months. I update my Arch system once per week, and last Sunday was a large update since xfce got a large overhaul (in terms of program and config files). However, since the update I cannot boot into OS X (I am posting this here instead of an OS X forum since no change occurred to the OS X system so the problem must be with a change to my Arch system).
When I attempt to boot into OS X, I am asked for my password to decrypt the partition, but then I get the following error message:
efiboot loaded from device: Acpi (PNP0A03,0)/Pci(1F12)/SATA(0,0)/HD(Part3.Sig698A

boot file path: \com.apple.recovery.boot\boot.efi
.............Read error 0x6

Error: Aborted returned from boot.efi
*Hit any key to continue*
When I hit a key, I get taken back to the refind menu. If I choose OS X again, I get the same error. This cycle can be repeated ad nauseam. Booting into my Arch partition, on the other hand, works just fine, with one hiccup. While usability does not seem to be reduced, after I input my password to decrypt the Arch partition, and before I see the tty1 login, I (since Sunday) occasionally get the following error message that I have never had before:
19.636262] [drm:crypt_set_fifo_underrun_reporting] *ERROR* uncleared pch fifo underrun on pch transcoder

19.332176] ata1.00: status: { DRDY }
The "READ FPDMA QUEUED" line and those below it repeat a few time with different numbers following "cmd" and "res," but then after a few moments the messages clear off the screen and I arrive at my tty1 login screen and from there everything in Arch (including my now-upgraded DE) works normally. This error does not occur during all boots, but I cannot discern any pattern behind when I see it and when I do not. The OS X error and failure to boot occurs every time I try to boot into OS X.
I have learned a lot as an Arch user, but this problem is beyond me. Google has not been particularly friendly, understandably so given the peculiarity of the problem and my setup. I have not yet tried undoing the update I did on Sunday because (a) it would be a pain since there were >30 packages that were upgraded, and (b) I have no evidence that the upgrade was actually causative of this issue, though I may eventually attempt the downgrade out of desperation if I cannot find a solution. Note that the update I keep referencing did not including a kernel update.
I appreciate any advice or insight that you can offer.

I don't have much in the way of a solution for your problem, but to start with, what were the > 30 packages? In particular, was grub/refind updated (or anything else that would likely touch your efi partition? I know from my own messing with refind, that you can potentially 'damage' your partition layout with certain commands which maybe causing osx not to boot...
Then again, the errors may have nothing to do with your arch installation and maybe indicative of a different problem all together. Normal procedure is at this point is to backup your complete disk (clone/mirror it, read up on how to do that especially with regards to the encryption systems used), and try to diagnose for any problems the mbp maybe having.
You could use an apple rescue cd (that may no longer be available with newer mbp , I have no idea..) or maybe use a different harddisk and install osx there and see if you can get everything running 'normally' thus ruling out any funky errors with the hw. check apple's recovery options if need be.
I guess you'll just have to fiddle about a bit and try to more closely determine what the actual problem is. and again, backup your stuff!

Windows 7 and Arch linux dual boot problem

hey guys I had an issue with windows 7 dual booted with arch and i was just wondering my windows 7 crashed. I had Reinstalled windows OS and all my partitions are set up but now when I try to boot up arch I cant at all cause windows Boot took over and i have no way of getting into arch is there anyway i can fix this or maybe reinstall arch without loseing my home folder with all my data, or is there just and easyer way to fix this issue im stuck. thank you all for your support as i am a noob

You need to re-install grub. When you reinstalled Windows it will overwrite grub preventing you booting Arch. You'll need to boot from a liveCD and chroot into your Arch installation. details for recovering grub are in the wiki - https://wiki.archlinux.org/index.php/GR … stallation

Windows 7 / Arch Linux Dual-Boot - win7 keeps changing the boot flag!

Greetings!
Its been a long while since I had to dual-boot with windows on the same machine.
I 've installed windows 7 and then arch linux and installed GRUB on my sda1 where the /boot partitions is located at.
I've managed to boot into arch successfully and later into windows also successfully.... but when i tried to boot into arch again I wasn't greeted with the typical GRUB boot screen... grub was ignored completely and win7 booting began as if it was the only OS in my hard drive.
I've used the gparted live cd and realized that the boot flag has changed from my /boot partition (sda1) to my windows partition (sda2). I've changed it back and I was able to boot into arch again. but when I rebooted to win7 and then to arch the same thing has happened. The boot flag keeps changing whenever im rebooting into windows making impossible for me to boot with GRUB unles I manually change the flag again.
I haven't installed GRUB into the MBR because I hear it is a bad practice when you have a windows OS also installed (something with service packs not being able to install, among other things). I also don't want to use the easyBCD method to boot arch using the win7 loader.
here is the partition scheme on my 500gb sata drive :
/dev/sda1 /boot 250mb (primary)
/dev/sda2 windows 7 ntfs 100gb (primary)
/dev/sda3 swap 4gb (primary)
/dev/sda5 / 16gb (logical)
/dev/sda6 /var 8gb (logical)
/dev/sda7 /home the rest of the hd space (logical)
What am I doing wrong and how do i prevent the boot flag from changing?
Thanks in advance for any help you can give me!

Win 7 and Arch dual boot [SOLVED]

There are other help threads about this, but I didn't want to hijack somebody's elses thread. Sorry for the long post, I just want to provide as much detail as possible:
I am trying to use Grub (not Grub2) to dual boot between Arch Linux and Windows 7. I had this working before using Windows XP, but when I reinstalled Windows 7 over Windows XP, Grub would no longer boot Windows.
1. If I manually choose the hd containing Windows 7 to load first in my BIOS, Windows 7 boots no problem. If I manually choose the hd with Grub and Arch to load first in my BIOS, I get a Grub menu, which boots Arch, but not Windows 7. Ideally, I think, I would like to have the internal drive with Arch ranked first, then the internal drive with Windows second in my BIOS. At least, that's how I had been doing things before blowing away XP and installing Windows 7.
2. Here is the (abbreviated) output of sudo fdisk -l
Device Boot Start End Blocks Id System
/dev/sdb1 * 2048 206847 102400 7 HPFS/NTFS
/dev/sdb2 206848 169934847 84864000 7 HPFS/NTFS
/dev/sdb3 169935570 1953520064 891792247+ 83 Linux
Device Boot Start End Blocks Id System
/dev/sda1 * 63 1028159 514048+ 83 Linux
/dev/sda2 1028160 3084479 1028160 82 Linux swap / Solaris
/dev/sda3 3084480 44050229 20482875 83 Linux
/dev/sda4 44050230 488392064 222170917+ 83 Linux
3. From that, I can tell that Arch is installed on sda: sda1 = boot partition; sda2 = swap; sda3 = root partition; sda4 = home partition.
Windows 7 is installed on sdb: sdb1 = system reserved partition (created automatically by Windows 7 during install); sdb2 = Windows; sdb3 = separate ext3 partition
4. I am comfortable editing Grub menus. This is an excerpt of mine:
# (0) Arch Linux
title Arch Linux
root (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/blah-blah-blah ro
initrd /kernel26.img
# (2) Windows
title Windows 7
rootnoverify (hd1,0)
savedefault
makeactive
map (hd1) (hd0)
map (hd0) (hd1)
chainloader +1
5. The error I get is "error 15: file not found" If I change the line reading "rootnoverify" to "root", I get the same error plus the bit about "filesystem unknown, partition type 0x7" so I think I'm pointing at the right partition/drive. That is, I know that partition type 0x7 is an NTFS filesystem/Windows.
6. I messed around with the Grub entry for Windows. I modified the root line to read "rootnoverify (hd1,1)", but things still did not work. I wasn't sure if I needed to bypass the "system reserved" partition created by Windows, or not. I also flip-flopped the two map lines, so they read:
map (hd0) (hd1)
map (hd1) (hd0)
That did not work either. I tried these combinations together, but Windows still would not boot. Always the same error message: "filesystem unknown, partition type 0x7"
7. I think I have a mapping problem given that Arch boots fine and Windows boots fine from the BIOS. However, I'm not sure how to fix this. Any help would be appreciated.
Thanks,
Culley
Edit:
Okay, so I fixed things. I just removed a bunch of stuff from my Grub entry. Even though Windows is not on the same drive as Grub, it does not need the map sections like I thought. I also removed the savedefault and makeactive entries, not sure if that made a difference or not. My new grub entry looks like this
# (2) Windows
title Windows 7
rootnoverify (hd1,0)
chainloader +1

Os 10.4, xp and linux. triple boot

Is there any way to have Mac OS 10.4.10, Microsoft XP service pack 2 Professional and Linux all on the same computer. I already have XP installed with bootcamp but, I wanted to try out Linux. I have looked at some ways to dual boot linux and mac and linux with windows. I don't think they would allow me to triple boot though. I would understand if this sounds far-fetched but I thought it couldn't hurt to ask. I appreciate any help that is given.

You can get an e-live live cd for mac and boot from live cd if this helps.

Wireless drivers pavilion 15 p157cl linux dual boot

I am struggling to get a dual boot to work fully on my machine.
The wireless on my computer doesn't work, and I am struggling to find what it may need to work fully. HP's site seems to not have my computer listed at all, or rather, the link is broken. because of this I can't find the drivers I need to allow for Wireless ussage.
How can I fix this?
On a related note, I would also like for my computer to give me the option of which OS to boot automaticly. Currently it just boots up windows imediantly on startup.
How can I change this?
Notebook model: HP Pavilion 15 notebook PC
Product number: J9H81UA#ABA

Hi:
There is no Linux driver that HP supplies for the Broadcom BCM43142 802.11bgn 1x1 Wi-Fi and Bluetooth 4.0 HMC combination WLAN adapter.
You'll have to check a Linux forum to see if anyone knows how to get that card to work in Linux.
If you need the windows driver, here it is...
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-137998-1&cc=us&dlc=en&lc=en...
You would also need this bluetooth driver...
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-137999-1&cc=us&dlc=en&lc=en...
How to choose what OS to boot from...
See if this works...
In windows, go to: Control Panel>System & Security>System>Advanced System Settings>Startup & Recovery>See the Default Operating System drop down and select the operating system you want to start as the default one.
Then you can set the time to display the list of operating systems to any time you want. 30 seconds is the default.
You might want to lessen that to 5 or 10 seconds if you are quick on the draw.

[Solved] Windows 7 and Arch Dual boot- unable to boot into Windows7

Had to reformat computer and reinstall windows and Arch on two separate hard drives (Dual boot) .
Windows 7 was the first install on SDA: (/dev/sda1 - system reserved 100mb, /dev/sda2 - 20gb)
Arch on SDB: (/dev/sdb1- boot 94mb, /dev/sdb2- swap, /dev/sdb3 - root, /dev/sdb4 - /home)
Installed grub2 on /dev/sda. now grub bootloader loads Arch fine. Also shows Windows 7 (on /dev/sda1).
But when chosen Windows 7, it does not load and loops back again to boot loader screen.
In BIOS i have set disk drive SDB as first boot option.
If i choose SDA as first boot option in BIOS, same scenario is repeated.
I have gone through mostly all the pages related to the topic but i can not co-relate the solution
to my exact situation due to limited knowledge.
Can somebody pls help me as to how to edit grub.cfg so as to point it to load windows 7?
the entry related to windows 7 reads as follows:-
quote
### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows 7 (loader) (on /dev/sda1)' --class windows --class os $menue$
insmod part_msdos
insmod ntfs
set root='hd0,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint$
else
search --no-floppy --fs-uuid --set=root F010D97410D941F0
fi
chainloader +1
unquote
for Arch set root value is hd1,msdos1 and working fine.
Thanks and regards.

Lion and Mavericks dual boot.

Hello everyone,
I have an rMBP with Mavericks its runs fine and i'd like to install Mavericks on my 2010 (white) Macbook as well.
The macbook currently runs 10.7 Lion and only has 2GB RAM, Mavericks will be even slower than 10.7.
Because of that reason and some others i'd like to dual boot 10.7 and 10.9 so my Lion partition remains.
I already created a partition for Mavericks but i have
a few questions and hope someone could anwser those..
1. Will Mavericks create a recovery partition ? and if so will it rewrite my old 10.7 ''Recovery Partition'' or will it create 2 seperate ones? (saw that in a vid)
2. If the installation of Mavericks fails will i still be able to boot to my current 10.7 partition?
Thanks in advance!

1. If you install them onto separate partitions, they'll each have their own recovery partition.
2. Yes.

Question about the "Windows and Arch Dual Boot" wiki

I've been reading this wiki http://wiki.archlinux.org/index.php/Win … _Dual_Boot to get a better understanding of what I need to do to install Arch along side of my XP installation and there's one point that I don't understand. Here it is
It is important to note that there is a 1024 cylinder limit with some older BIOSs. This means that the BIOS cannot access things beyond the 1024th cylinder (about 8.5GB), so the /boot partition should be in the first 8.5GB (space before Windows partition).
How does one go about getting the /boot partition created during the installation of Arch to install in the first 8.5g? I have installed Arch in Virtualbox twice so far just so that I'm familiar with the procedure and I can't see anything in the installation where I can do this.
There's one other item that is not clear to me as I've seen conflicting information on it. If I do create a seperate "/boot" partition for Arch, do I need to make it "bootable"during the installation? At this point I don't think that I do.
My understanding of installing to be able to dual boot is that I only need to install Grub to "Sda" and of course edit the grub menu to add the information needed for XP. Is this enough?
Thanks for any help.

Yes, you install grub to sda (master boot record), and add the entry for Windows. In the step where you partition the harddrive, you can choose where to create it. Actually it may not be that much of a problem anymore, my boot is on the third partition, after ~15 GB. You can forget about the bootable flag when using grub, it does not care.
