How to boot arch faster?

I have a P2 350 with 192meg ram and 4meg nvidea riva 128 video card.
I dual boot (via lilo) between win95 and arch 0.7 updated.
When booting Arch i login as a user directly through alternative login in inittab and startx to windowmaker via ~/.bash_profile.
With hotplug enabled bootup from the lilo screen to windowmaker it takes 1minute 30 secs to load - way too long I think.
With hotplug disabled and modules enabled in the modules setting of rc.conf it takes about 1 min. 10 secs.
So I save about 20 seconds doing this.
But it still takes about 15-20secs to load all the modules this way.
Are there any other ways I can reduce this time?
I would at least like to get it under a minute.
1. Would compiling my own kernel with all modules built in statically make any difference?
2. would this mean I could disable both hotplug and modules in rc.conf?
3. Any other ways I can reduce the time for boot.
I have seen other posts suggest using "compact" in lilo.conf but that makes no difference to me.
I am not concerned about general performance just boot time.
Here is my modules and daemons lines from rc.conf and the resulting output from lsmod.

I am not sure what could be loading these and why?
If you can't get rid of them I wouldn't worry - I think evdev loads up on my machines sometimes... "rtc" is "Real Time Clock" IIRC, and it's kinda important. Even if you get rid of them, there's going to be no real time effect.

It took me some time to work out what was the correct entry in lilo.conf for bootchart to work, but eventually I got it.
I had to add to the vmlinuz parameters append="init=/sbin/bootchartd".
I have produced the .png and viewed it, but from there I don't know how to interpret the graph or what it can tell me.
What should I be looking for?
It tells me that boot time was 30.43 seconds which is way out on what I timed it to be. The graph seems to include the starting of X so i am not sure why the time difference, except to say that the starting of bootchart doesn't seem to happen until just before the loading of devfs in the bootup sequence.
Well, it's measured from a different point than you're probably measuring from. You're probably measuring from the time you press the button to the time X is usable. Bootchart measures from the point the kernel spam begins to the time it loads X (but most likely not when it's usable).
The reason I suggested bootchart is not the time (though that's really good for a 350MHz - I've seen 2-3GHz machines spit out bootcharts for 20-30 seconds most of the time) but because you can see what takes the most time and try to minimize that. Can you upload your bootchart to imageshack or something so I can take a look at it?

Hah, too much of my time? Look at my post count... I spend way to much time here as it is (4.56% of total / 6.58 posts per day).
The biggest time killer is most likely X right now. Maybe you can try slim (package is in the [community] repo) in place of xdm, see if that speeds things up? I'd add the "@slim" daemon first in the DAEMONS array, so things appear usable just slightly before they actually are - it's all about illusion 8)

How to install Arch for dual-boot with Win 7 (on 2 hard drives)?

Hello,
the TLDR first: how exactly should I proceed when setting up GRUB for 2 hard drives to dual-boot Arch (64 bit)and Win 7 (64 bit)?
Long version: So, I have the following hard drive & partition layout:
On my first hard drive (250 GB big) I have: Win 7 64 bit, all the programs for Windows and of course the EFI partition
My second hard drive is 1 TB big and formatted in NTFS and it only contains data. It has 2 partitions, one is about 750 GB big and used for simple storage.
Sidenote 1: sometimes my disk management (Windows' own gparted) shows either the little disk or the big one as disk 0. Don't know what exactly this means, but I have never ever experienced any problems whatsoever during use.
Sidenote 2: the UEFI motherboard (ASRock H67M) cannot boot into Legacy mode.
I want to install Arch on a ~200 GB partition on the second hard drive (the one with 1 TB). (click here if you want to see a screenshot) I am posting this because I am confused with how exactly I should deal with the whole "2 hdds & UEFI" thing.
So how exactly should I proceed when setting up GRUB for this setup?
For partitioning I suppose I would have to use fdisk or cgdisk. I used cgdisk before and found it to be straightforward. Then, because I have experienced my fair share of problems with rEFInd, I'd like to use GRUB.

First thing you should do is become familiar with your motherboard.
http://www.asrock.com/mb/manual.asp?Model=H67M
This will probably help you out in understanding the sidenote 1 thingie (hdd's on sata3 and/or sata2 connectors)
As on sidenote 2, according to the manual it seems to be possible to boot legacy mode, see Storage Configuration.

How do it get Firefox to work boot up faster? How do I get my bookmarks to stay alphabetized in my toolbar?

Lately my usually reliable Firefox has been taking longer and longer to boot up, how can it be made to boot up faster?
== This happened ==
Every time Firefox opened
== A few months ago

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
Create a new profile as a test to check if your current profile is causing the problems
See [[Basic Troubleshooting|#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

How to install arch 2009.08 from hard drive? Please enlighten me

OK, I admit I am impatient for the installation from the CD drive. Whenever possible and whatever distro I wanna try, I head first to try to install it from the hard drive. I don't remember how many times and how many distros I have done the same to, ubuntu, zenwalk, sidux, fedora, opensuse and of course arch. It rarely failed as long as I followed someone's guide, sth like "install any OS from hard drive", I do not exactly remember. And I did the same in the past with arch. But after 2009.08, it simply didn't work. I've read the article "fast install arch from existing linux system" in the wiki, it didn't work either (by the way, if someone can solve my problem, I think the article should be updated). After it boots, at some stage, it says "Use Hook [archiso]", then tell me "waiting for /dev/archiso for 30 seconds ..." then when the time due, it throws me into a ramfs shell. I've hacked for a long time, but no luck. Then I went back to download the 2009.02 iso, however, it works flawlessly.
I did find some differences in the menu.lst/isolinux.cfg between two version.
In 2009.02, we have
title Boot Arch Linux Live CD
kernel /boot/vmlinuz26 lang=en locale=en_US.UTF-8 usbdelay=5 ramdisk_size=75%
initrd /boot/archiso_pata.img
While in 2009.08, it is
title Boot Arch Linux Live CD
kernel /boot/vmlinuz26 lang=en locale=en_US.UTF-8 archisolabel=ARCHISO_AHCOHH6O ramdisk_size=75%
initrd /boot/archiso_pata.img
I know I can install arch from usb, but I simply wanna know what's wrong here, so guys, if you have any idea, don't hesitate to enlighten me.

Hi, vacant, thanks for the reply. I did not notice you are the author of the article. Actually I missed the head of the article which directs me to another (the amalgamated one you mentioned). I take a look at it, it seems to make things complicated. I still miss the old days: you simply download the iso, mount it and copy all the contents into a separate partition, edit your current grub, then reboot and everything works. I don't understand how Arch could be so evolved to exclude this simple installation scheme. I am not complaining the development of Arch. In my opinion, a distro as flexible as Arch should provide as much installation strategy as possible. In this respect, I think we can learn from Ubuntu or sidux (in sidux, it provides a very convenient kernel parameter called "fromiso" which allows you to install sidux from the plain iso, that means, you even don't have to mount it and copy the contents out of it to a separate partition).

How Long Will Arch last?

Hi, my question here is not to ridicule (or otherwise designed to offend anyone) but one of concern. Many distributions have a viable economic model which helps ensure that the distro can survive (Fedora is one prime example). The fact that Fedora has the backing of Red Hat means that it is almost always asured funding. Ubuntu is also moving in this general direction (although their model does not seem as reliable as Red Hat's yet.) What gurrantee do we have that Arch can last for many decades to come? The Arch devs are real people with real jobs. As far as I know they do not actually get and money from Arch Linux. What sustains Arch ( pays for servers etc.) Is it simply donations? Can Arch survive soley off of donations?
What are your thoughts and ideas do you have on how to make Arch a self sustaining distro while also keeping it free? Finally if Arch falls apart what would you do?
THIS IS HYPOTHETICAL THIS IN NO MEANS IMPLIES THAT ARCH IS GOING UNDER ANY TIME SOON!
( I would also like to take this time to conragulate the Arch devs for coming this far and thank them for all their work it is much appreciated.)

Read the FAQ (Introduction page) for more info about Unununium:
http://unununium.org/introduction
Something interesting:
On what platforms does Unununium run?
The latest plan is to implement Unununium as a Linux userspace process. Linux is a stable, available, well documented program which eliminates most of the mundane, uncreative aspects of usual OS development such as writing hardware drivers. It also provides an easy mode of execution, with a developed debugger such as gdb, and fast boot times, since there is no need for a full hardware reboot. This makes development much easier.
Running on Linux has disadvantages as well. Probably most significantly, some things are slower. For a slower speed in execution, we get a faster speed in development. Some day it would be nice to reduce overhead, but that's something that will wait until there is something running.
For some reason or another, this choice of platform leads people to question if Unununium can really be an OS. Of course, it really depends on how "OS" is defined. Unununium is an environment and a design common to all programs which depend on it, and in this sense might be considered an OS.

How to Boot From an External HD

I am still pondering getting a mini - I know that I will want a much larger hard drive (since I want to use it for media and will keep tons of video and music on it). I would like to know how to boot from an external hard drive. I've searched google, the forums, and apple support, and see people mention it all the time, but can't find out how to do it, etc. Is it just like running off my normal HD but all the files are kept on the external (so I could still access files thru itunes, etc.)?
Also, I would like to get a 500GB+ drive to keep my files on, and was wondering if people had recomendations. Brands, USB 2.0 or Firewire, etc.
Apologies if this is a novice question - but I can't seem to find answers anywhere.
Thanks in advance.

Firstly, it is certainly possible to boot from an external drive, so what you plan is not only feasible, but since the external would be faster than the internal drive, also rather beneficial to the efficient running of the mini - meaning, the system will be notably faster in use.
In my view, the best option is an external firewire drive, not USB. The reason is that FW has it's own dedicated controller while USB doesn't. In effect, it means that FW data transfer speeds are stable and consistent, while USB rates vary widely, depending on what else the system is doing.
Once you have your external drive connected, the easiest way to make it bootable is to copy your existing MacOS install from the internal drive using software such as Carbon Copy Cloner (downloadable from www.versiontracker.com). This will avoid having to do a lengthy reinstall. Once MacOS is copied, then open System Preferences, and the Startup Disk preference pane, and click on the external drive icon. The next restart will then be directed to the external.
Once you have booted from the external drive, you use it just as you would an internal, and MacOS will treat it as the boot volume, including by default, placing your user account folders on it, including your documents, music etc.

[Success] Dual Booting Arch and Windows 7 [Advice / Confirmation]

So I have been trying to get Starcraft II to work with wine and no luck.
I have decided to install windows back on my computer, besides it might come in handy since I'm heading back to school soon.
Anyways I have tried dual booting arch and windows in the past, and my results have never been stable.
Today I will try using the program gparted.
Let me give you my thoughts on how I plan to go through this and please give me some advice so I don't loose everything I have worked for on my linux box
1.Currently I have two hard drives, one for all my main programs and one for my media files (mounting usb, dvd, etc, and it actually has no files in it xD).
I plan to use gparted to re-size my second harddrive (media drive), create an extended partition, and a logical ntfs partition within it.
2.I pop in my windows cd that I recieved with my laptop and install it on the space I have partitioned for windows.
3. If my grub gets wiped out my windows (which I hope it doesn't not sure how the MBR stuff works) I insert a Ubuntu live cd and do
sudo grub
> root (hd0,0)
> setup (hd0)
> exit
4.Configure grub to boot windows 7.
5.Be happy with no headache.
SO....
If someone with past experience with dual booting windows and arch could please give me some advice, as I do not want to lose all my data, start over, and have another headache.
I know I must learn to backup arch, which I will before september.
But if anyone has any protips, or sees a flaw in my plan please point it out!!!
Thank you very much for taking the time to read this and even more if advice has been given to boost my confidence!
For now I will wait
Thank you fellow archies.

1) Windows must be installed to a primary partition - attempting to install it to an logical partition will result in an epic fail
2) Physically disconnect the harddrive you do not want windows on as windows typically installs the bootloader on the 1st hardisk (ie /sda) regardless of installation drive (ie /sdb)
3 / 4) Complete the windows installation then reattached your Arch drive and edit /boot/grub/menu.lst (as root) pointing the W7 entry to (hd1,0) - no need to reinstall grub
5) Hey it's windows - anything could happen
If you create an NTFS partition right at the beginning of the the drive before you start the W7 install you can prevent it greedily using up 2 of you 4 primary partitions - I would also completely update you new W7 installation past SP1 before reattaching the other drive to further prevent W7 going mental
satanselbow thank you so much!
Everything works great I had no stumbles, and I hope no problems in the future!!
I will post exactly what I did in case someone has the same issue.
1. Partition you're secondary harddrive as primary ntfs with gparted
2. Reboot, and if you get a file system check error, check you're udev rules. (For my case in particular I had to change the udev rules I got for auto mounting usb, ext harddrive, etc.
3.Power off your computer and physically remove the harddrive that contains all your linux goodies
4. Plug in your windows cd and install in the partition you created
5. Update your windows OS
6. Plug in Ubuntu live CD and reboot
7. Use commands to get grub to overwrite the windows boot loader (In my case I put grub everyone hd0,0 hd0,1 just to be sure, but you might want to do things cleaner)
8. Reboot and see if grub loads up
9. Use Ubuntu live CD again and launch Gparted, select the boot to your extra linux space (if you had one, not sure if this is needed)
10. Plug in your linux harddrive and reconfigure /boot/grub/menu.lst and your good to go
Once again shout outs to satanselbow!!! For without him I might've failed brutally!
Cheers!

Dual booting Arch and Ubuntu

Hi, I would like to dual boot Arch and Ubuntu using GRUB2.
I already have Arch, set up as it's described in the Beginner's Guide, with GRUB2 installed. How would I go about dual booting Ubuntu, preferably without overwriting the existing bootloader?
I haven't tried anything yet, but the problem that I can see is resizing my /home; is this possible on the Ubuntu liveDVD? If not, would I be able to resize /home with my gParted liveCD?
Unfortunately, I have no backup media to use, so I wouldn't be able to transfer anything away as a backup.
Here is my partition table:
%lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 30G 0 part /
├─sda2 8:2 0 12G 0 part [SWAP]
├─sda3 8:3 0 5M 0 part
└─sda4 8:4 0 889.5G 0 part /home
sda1 is my root partition, sda2 is swap, sda3 is GRUB's boot partition, which I was told that I needed in the guide, and sda4 (/home) occupies the "rest of the disk".
I am using a GPT-partitioned drive, as I read this has many advantages and I do not plan to triple-boot Windows.
So, can someone tell me what I do if I want to dual boot Ubuntu? I'm very sorry if this should have been posted on the Ubuntu forums, but I'm just more familiar with Arch, and I already have it installed. Please ask if you need any other files like my fstab. I have my Ubuntu liveDVD, GParted live CD (and Arch CD) at hand.
Thanks in advance, rberyl.
(Also, does anyone else think it's a bit of a backwards thing to put the output of "date -u +%W$(uname)|sha256sum|sed 's/\W//g'" as a sign-up question? )
Last edited by rberyl (2012-12-29 11:45:23)

Hi rberyl,
You can change your partitions using an inbuilt tool like cfdisk, or if you'd prefer a GUI gparted can be installed from the Arch repos. This will allow you to shrink sda4, and set up the new partitions for your Ubuntu OS. Although this shouldn't cause any data loss, its best practice to back up just in case.
When installing Ubuntu, be sure to opt-out of bootloader creation. I think you have to use the alternate installation media to get this option. You can add your Ubuntu partition to the existing bootloader by running osprober (available from the repos) and then running grub-mkconfig -o /boot/grub/grub.cfg . Alternatively, you can manually edit your GRUB config. See https://wiki.archlinux.org/index.php/GR … NU.2FLinux for instructions.
Good luck!

[SOLVED] Wiki page for GPT disks and booting arch using UEFI

Hi guys, I am new to archlinux. I installed archlinux x86_64 just yesterday and I like its customisability. I also like arch wiki. Nowhere else have I seen such extensive documentation, especially about things like HAL, UDEV etc. with proper instructions. Thanks to all archers.
I have installed Archlinux x86_64 in my Dell India Studio 1537 laptop along with Windows 7 Professional x64. Both the OSes boot in UEFI-GPT setup (my UEFI is tianocore.sourceforge.net EDK DUET UEFI64 firmware booting from USB). I boot Archlinux using my own compiled grub2-bzr compiled for both BIOS and UEFI-x64. I have a 1 MB BIOS Boot Partition as required by grub2 for BIOS-GPT booting. My Archlinux system can boot both from bios and from uefi, while Windows can boot only using UEFI.
The official Archlinux installation guide talks about only MBR (or msdos disklabel) partitions and booting from BIOS based systems. With 2TB drives becoming common place and UEFI being implemented (search for Phoenix SecureCore Tiano's 1 second POST operation), I think a proper wiki page describing differences between MBR and GPT, why GPT is better, how to setup arch to boot from GPT. Another page describing steps to setup arch to boot from UEFI (either as a separate page or as an extension of GRUB2 wiki page) is also needed.
Some details regarding Pure GPT (not a Hybrid GPT/MBR setup) and/or UEFI setups :-
Partitioning tools -
GNU Parted for filesystem related tasks
GPT fdisk tool - http://rodsbooks.com/gdisk/ , http://sourceforge.net/projects/gptfdisk/ , pacman -S gdisk (in extra repo) - for non-filesystem related tasks
util-linux-ng fdisk does not support GPT disks
Bootloader - GRUB2 - vanilla grub-legacy does not support GPT and does not support UEFI (Fedora's patched grub-legacy does support both GPT and UEFI) and syslinux does not support GPT (I may be wrong here - seems a gptmbr of syslinux does help in booting from gpt but not sure).
For GRUB2 - Need BIOS Boot Partition to embed GRUB2's core.img in GPT disks - size about 1 MB max - no filesystem
In GPT fdisk partition type code - EF02
In GNU Parted or GParted - bios_grub flag on
For UEFI-GPT booting this special partition is not needed as no embedding takes place. This is needed only in case of BIOS-GPT booting.
Incase of custom kernel configuration - enable CONFIG_EFI_PARTITION for GPT support
CONFIG_EFI for UEFI support (for UEFI even above option required)
CONFIG_EFI_VARS for UEFI Runtime Variables support (optional)
Note: Although GPT is part of UEFI specification, a UEFI system is not needed to boot from/use GPT. BIOS based GPT booting is possible with GRUB2 or Fedora's patched grub-legacy (but not vanilla grub-legacy provided by archlinux). It is also possible to boot Linux in UEFI-MBR setup (again using grub2) but I have not tried it.
Even without UEFI and less than 2TB harddrives, GPT based partitioning has many advantages - secondary GPT header and Partition table, CRC32 checksums. Unique Disk GUID and Filesystem-independent Unique Partition GUIDs, multiple primary partitions (default is 128 partitions, but it can be changed). The only problamatic OS is Windows which does not allow GPT booing unless one has UEFI based system. It allows only UEFI-GPT or BIOS-MBR setups. In linux it just depends on how the bootloader is configured - not a problem with grub2.
I also propose that incase of Auto-prepare Hard Drive, the installer default to GPT for "archlinux only" installs ( ie no dual-boot or triple-boot etc.).
I did not use the official archlinux iso but used archboot 2010.04 R3 as it gave an option of installing to GPT and also provided GRUB2 during bootloader install. I have never edited any wiki page before, thats why I request some one else to start a wiki page with the information given above.
I don't know whether this is the right place, but any Windows (Vista or 7 x64 versions) and Linux dual-boot user who has UEFI-based system with GPT partitioning and wants to get rid of Hybrid MBR setup (to boot Windows) can follow this post http://www.insanelymac.com/forum/lofive … hp/t186440 (outside this forum) - this link describes the way to make Windows boot natively in UEFI-GPT setup. After doing this one can install arch using GRUB2 compiled for UEFI x86_64, and Windows will also see

Welcome to arch, skodabenz! Offering documentation on third post - all thumbs up
You could start the wiki page in your user-space with what you have, and then invite others to join working on it. Just register a wiki account, navigate to the page you want to start, for example:
http://wiki.archlinux.org/index.php/User:skodabenz/GPT
and click on "edit this page".
As noted in the other thread, arch's legacy grub is patched for gpt support. I don't know about UEFI, but you can always open a bug report asking for the patches from fedora to be included.
edit: the page from Rod Smith is a great resource. I was absolutely terrified at first by all this screwed up GPT/MBR stuff when I tried triple-booting Arch, Win and OS x, but he really does a great job explaining what it is all about.

How to boot your phone into safe mode

If you experience any problem with your phone, booting it into safe mode can be a good idea to check if any third party applications might be involved in the problem you’re having.
If you run your phone in safe mode for a while and you don’t experience any problem, the problem you’re having is most likely related to a third party app that you’ve installed.
How to boot into safe mode differ from models to model and it can also be different depending on firmware version but this topic will explain to you how to do it.
NOTE!
Booting into safe mode may change personal UI customizations such as icons and folders.
Later Xperia phones running on Android Jelly Bean (Android 4.1 or later)
Press and hold the on/off key until you get this screen.
Now tap and hold the Power off option until you see this screen.
Press OK to reboot into safe mode.
If you have successfully booted into safe mode you will see the text Safe mode in the bottom left corner.
You can also boot into safe mode by turning off the phone and wait a few seconds. Now press and hold both the on/off and volume down (-) key. Keep pressing these two keys until the phone has booted completely.
To exit safe mode you simply power off and power on as normal.
Xperia phones using touch menu key running on Android GB (2.3.X) or ICS (4.0.X)
Turn off your phone. Wait a few seconds and then turn it on again. Now during the boot process start tapping the menu key continuously and keep tapping until the phone has booted completely. Not too fast, not too slow. The beat of Iron man by Black Sabbath is just right.
To exit safe mode you simply power off and power on as normal.
Xperia phones using hardware menu key
Turn off your phone. Wait a few seconds and then turn in on again. Now during the boot process press and hold the menu key until the phone has booted completely.
To exit safe mode you simply power off and power on as normal.

[SOLVED]Gummiboot cannot boot arch

Hello. I've been reading the wiki guide until the end when i got stuck. I have windows 8 installed with a UEFI mobo so i just used the same ESP for arch. Now i try to boot arch but get a "vmlinuz not found" message. What did i do wrong?
while still on live cd i mounted the EFI partition (/dev/sda2) to /boot (same root and home partition) and then installed and configured gummiboot as described.
Do i have to add that ESP to the fstab file? Or how to fix it?

Load up the Arch live ISO, mount your partitions and use `arch-chroot` then post the output of:
ls /boot
# efibootmgr -v
lsblk -f
# parted -l
You can use `sprunge` to post the output of the commands.

How to boot leopard from cd?

Hey guys,
Maybe a silly question, but I need to know how to boot leopard from its insallation dvd, is that possible?
I would like to boot my mac from dvd, so that i can then use the disk utility to partition my internal hard drive, and i think this is only possible if you dont boot from the hd it self.
Obviously I am able to boot from the dvd in the way that it starts the leopard installation, but thats not what i need i guess? at least when the installation start, i dont see an option to start disk utility from there?
so i need to actually boot the system from the dvd, in order to partition "on the fly" without losing the data on my disk.
I hope someone knows.
thanks in advance.
cheers,

Hi,
Boot from the Install disc. Select the Language. Then as soon as the menu bar appears you'll see a Utilities Menu. Select Disk Utility from there.
cheers

Boot arch from iso and grub2

Hello,
I'm trying configure grub2 for boot iso image of arch but don't work:
My grub.cfg entry is:
menuentry "ArchLinux ISO" {
loopback loop (hd0,3)/iso/arch.iso
linux (loop)/boot/vmlinuz26 findiso=/iso/arch.iso lang=en locale=en_US.UTF-8 archisolabel=ARCHISO_KE1AECIE ramdisk_size=75%
initrd (loop)/boot/archiso_pata.img
boot
Arch start correctly boot fail and hope 30 seconds for image of /dev/archiso, I think.
Is the above entry correct?.
Regards.

I wouldn't really call it a bug. It is more like an enhancement that Arch Linux does not currently have, AFAIK.
example:
menuentry "Arch Linux 2009.08 netinstall 64bit" {
loopback loop /boot/iso/archlinux-2009.08-netinstall-x86_64.iso
linux (loop)/boot/vmlinuz26 lang=en locale=en_US.UTF-8 archisolabel=ARCHISO_OHD8FOH5 ramdisk_size=75%
initrd (loop)/boot/archiso_pata.img
What happens with the grub2 is as follows:
loopback loop /boot/iso/archlinux-2009.08-netinstall-x86_64.iso
1) mount the iso image as a loopback
linux (loop)/boot/vmlinuz26 lang=en locale=en_US.UTF-8 archisolabel=ARCHISO_OHD8FOH5 ramdisk_size=75%
2) load the kernel from the iso image (and pass command line options)
initrd (loop)/boot/archiso_pata.img
3) load the initd from the iso image
The problem comes after this.
Once the kernel and the initd are loaded grub2 leaves the picture, as well as the loopback iso image.
The loaded kernel starts the boot process and looks for the files/filesystem it expects to be there.
But it can't find it because the iso loopback device is gone (or as far as it knows, never was there to begin with).
To get around this problem many distros include kernel command line options such as:
iso-scan/filename, findiso, and isofrom
These command line options are pretty much scripts to find and mount the iso image and use it as the root partition. Much like what we did with grub2.
I don't know if the command line options are part of the initd or the kernel itself, but either way I would like to see it as part of Arch Linux default iso.
If I knew how to modify the initd I would make a patch for it or the iso as a whole, but my knowledge doesn't go that far

[SOLVED] Triple Boot Arch Linux, Windows 7 + Windows 8 on second disk

Hi,
I have installed Arch Linux and Windows 7 on my primary disk. Everything's perfect. I want to install Windows 8 on my second disk. My only problem is how do I make grub2 recognize Windows 8 on the second disk and add it to the grub file, so i can boot Arch, Windows 7 and Windows 8.
Thank you for your time,
Deadvi

It overwrote the MBR from the first disk, even though you installed Windows 8 on the second disk? That's odd... Make sure that the boot order in the BIOS is right (that the drive with Arch Linux is the first to boot) and from a 2012 Arch Linux install media run:
# mount /dev/sdxY /mnt #Your root partition.
# mount /dev/sdxZ /mnt/boot #Your boot partition (if you have one).
# arch-chroot /mnt
And continue with the instructions from here. If you don't have a 2012 Arch Linux install media (or you only have some other "live" Linux distribution), use the old chroot way.
