Solaris 10 on extended partition?

Hey all
I need your help in something, as I'm a Linux junkie
but a Solaris noob. I'm currently working with an 80
GB hard drive with Windows XP (ugh) installed on the
primary partition and Linux (Fedora Core 4) on
extended partitions. Needless to say I'm using the
Linux bootloader.
I'm downloading Solaris 10 at the moment. I read
somewhere that you can't install Solaris 10 on an
extended partition. Is that so? Because I was
originally considering installing Solaris in Linux's
place (not that I'm sick of Linux, but because of a
lack of free space on my drive).
If I have to install it on the primary partition,
that means I have to get rid of Windows instead. Is
that a risky thing to do? Because I can't afford
losing the important data I have, which is all on
extended partitions. And will there be any issues
concerning booting Linux and Solaris?
I also have this old 10GB hard drive lying around
somewhere that doesn't work. Would it be the best
idea to have it repaired and installing Solaris on it
and keep the old systems?
Please help me out
Thanks in advance
-AHi,
I've just got this working fairly well, Windows XP Pro-
50gb, FC4-10gb, Solaris 10-9gb, and Fat32- 7gb.
That is the correct order to install them. Originally, I
was going to use BootMagic as the boot loader. So
I installed FC4 to the first sector of the boot partition.
That works well for Linux and Win XP but Solaris 10
required the "Advanced" BootMagic configuration.
Then I decided to try to make this work with boot.ini
I used the dd command to copy the first 512 bits of
the first sector of the Linux boot partition, linux.bin.
Here is my boot.ini and linux.bin is on C:\
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
c:\linux.bin="Linux"
So when I choose "Linux from the boot.ini options, the
grub boot loader presents me with Windows as the
default, or I can choose FC4 or Solaris 10. I read that
Solaris 10 requires the "makeactive" switch and I
included it for Windows XP so that I wouldn't have to
make Win XP active since I use it the most; it saves
the Solaris 10 boot loader screen most of the time.

SH: I think you could use Mepis as a much smaller
Linux that would provide the grub boot loader -- Boot
Magic is 13mb and costs money. Also remember to
conserve on separate primary boot partitions since
you only have 4. Solaris 10 cannot be installed in an
extended partition nor does trying to make it boot
directly out of boot.ini work, but indirectly thru grub.
I used Partition Magic at first but it gets hosed after
the Solaris 10 install and it is a bit of work to fix it so
I used Win XP Computer Management--> Disk
Management later to create the fat32 parition and
bootit Ng to create the swap partition, which is free
as long as you don't install it to the hard drive. (trial)
This is easier with two master hard drives connected
to two different ide connectors on the motherboard,
slave the cdrom(s), if both disks are working well,
since you can use the MBRs without worry.
Good luck,

Solaris 10: Mounting a extended partition

Hi, I have Solaris 10 installed in a x86 machine.
I have one hard disk with 3 primary partitions (ntfs, ufs, fat32). I have 1 extended partiton that containts 2 partitions (ext3 and fat32).
Can i mount my extended partitions in Solaris?
I mount my first fat32 (hda2 in linux) partition with:
"mount -F pcfs /dev/dsk/c0d0p2 /mnt/ruben"
In wich way can i mount my second fat32 partition?
"mount -F pcfs /dev/dsk/c0d?s?p? /mnt/david"
Can i mount my linux partition?
Finally, in wich way can i mount my Solaris partition in linux?
I try "mount -t ufs /dev/hda3 /mnt/solaris/
" but it doesn't work.
Saludos.
PD: Sorry for my sucks english :)

Solaris 10 won't reconize your extended partitions, its limited in primary partitions only at this time. This may change ofcourse, it wouldn't surprise me if you see support appear somewhere in either Solaris Express or a later Open Solaris release.
Mounting your linux partition is therefor only possible if its located on an extended partition. As to Linux itself; it heavily depends on the filesystem. I think to have read somewhere that you can add ext2 support in Solaris, but I don't think that'll work for filesystems like reiser, xfs or ext3. (although the latter might be accessible as ext2).
Finally, a little offtopic (but not too much)... Yes, Linux supports mounting Solaris x86 slices, but its very likely that you'll need to recompile your kernel. You'll need to add UFS filesystem support as well as support for the Solaris/x86 partition table.
I suggest checking out a few howto's on www.tldp.org on instructions how to compile your kernel.

Solaris-x86 mount fat32 partition, the partition max size limit?

solaris10 x86, laptop, 10G FAT32 partition for windows & x86 exchange data.
the fat32 partition mount as normal, can be read fine.
but write some file by x86, that can not find by windows.
anyboy know did the solaris-x86 mount fat32 partition, the partition max size limit? or no limit, why this problem occur?

Mounting Windows partition in Solaris
The easiest way to share data now is to do it through a FAT32 partition. Solaris
recognises it as partition of type pcfs. It is specified as device:drive where drive is
either the DOS logical drive letter (c through z) or a drive number (1 through 24).
Drive letter c is equivalent to drive number 1 and represents the Primary DOS partition
on the disk; drive letters d through z are equivalent to drive numbers 2 through 24,
and represent DOS drives within the Extended DOS partition.Syntax is
mount -F pcfs device:drive /directroy-name
where directory name specifies the location where the file system is mounted.
To mount the first logical drive (d:) in the Extended DOS partition from an IDE hard
disk in the directory /d use
mount -F pcfs /dev/dsk/c0d0p0:d /d
You can use mount directory-name after appending following line is in
/etc/vfstab file
device:drive directory-name pcfs no rw
for example
c0d0s0:c /c pcfs no rw
If your windows partition like the following means
C: - NTFS, D:-FAT32, E:-NTFS, F:-FAT32
Then you can only mount D, F not C & E.
Mounting D Drive:
mount -F pcfs /dev/disk/c0d0p0:c /mountpoint
Mounting F Drive
mount -F pcfs /dev/disk/c0d0p0:d /mountpoint
The driveletter only for fat not including other file systems (ntfs or any linux filesystems).

Lost one primary and two extended partitions - testdisk isn't working

Hey everyone... long time no see. I needed a break
("Conclusion" below if the following is TL;DR)
Background:
First up... don't pull the plug on your PC, even if you are over-fatigued, and try to minimize the number of times you have to force-switch your system off. Read on if you would like to know why.
About four days ago, I was working on something, and everything was all good. Nothing was wrong, awry, or weird, and the only thing I could've written home about my partition structure was that cfdisk showed all the metadata for my extended entries.
That all changed one simple reboot later.
Three days ago, I greeted a system that booted up perfectly, and before entering X I decided to work on a document in textmode. Once I'd had enough of that, I fired up X and continued working on some changes to the QEMU VGA BIOS that makes it look like an old 512K VGA card from 1991 that I have. Or rather, tried to. I fired up my editor and a console and tried to compile... and /stuff, /dev/sda4, wasn't mounted. No problem; it isn't in my fstab. I should get around to adding it one da--whoa, what the...? /dev/sda4 is SWAP?!
It got worse from there. Three days ago I was extremely fatigued because I left a CRT plugged in that I don't usually plugged in (and I didn't know until the next morning!), and being tragically sensitive to radiation, I was rather unreasonable (and had been all day, even while away from the computer), so didn't think clearly about what I did next.
First, I proceeded to use cfdisk to change the partition type from 82 (Swap/Solaris) to 83 (Linux). The partition table decided not to "catch", so cfdisk pointed out that the prudent thing to do would be to reboot, which I ignored (major failure #1) and fired up TestDisk to try and fix (major failure #2) and was like "Enter, enter, enter, enter, enter, enter, ^C, reboot" (catastrophic failure #1).
***************** FILESYSTEM CHECK FAILED ****************
* Please repair manually and reboot. Note that the root *
* file system is currently mounted read-only. To remount *
* it read-write type: mount -n -o remount,rw / *
* When you exit the maintenance shell the system will *
* reboot automatically. *
The rest was history, unfortunately.
I had a 26GB "hole" of free space in my hard disk and... eek. Deciding I'd done enough damage, I fought off my OCD/Autistic "GAH, the computer is DEAD, DO SOMETHING" and got some sleep.
The next day (the day I discovered the CRT was off but plugged in) I decided to have a crack at fixing the problem.
Conclusion:
Worst case scenario, I thought, would be that the 26GB of data was simply gone, and best case, I'd have a ~5GB hole in the disk someplace that would hold my two Syllable AFS partitions (partition type 2A), which I was sure no utility I knew of would be able to figure out. I was almost completely correct: I got my 17GB /storage partition back (WHEW), but I lost my two Syllable partitions as well as a third primary partition of unknown filesystem type.
Here's my evidence:
Going through /var/log reveals files showing lines like
messages.log.2:May 14 10:27:53 hornet sda1 sda2 sda3 < sda5 sda6 sda7 sda8 sda9 sda10 sda11 sda12 sda13 > sda4
This proves that sda4 did once exist as a real partition and wasn't mountable as the result of a freak accident on the disk.
In addition, sda4 is indicated to be a primary partition at the end of my extended partitions. This makes me wonder what on earth's happened here, because I only have a single "Free Space" hole inside my extended header, not after it. Did the extended partition header somehow manage to get resized? :S
I remember - and have the .bash_history to prove - that I chowned and chgrp'd /stuff (ie /dev/sda4) such that I could read/write it as my own user, and this isn't possible with FAT* partitions - you have to dive into /etc/fstab to make them user-writable, and I know I didn't do that. So this partition is possibly ext2, ext3, or JFS (and I'm thinking JFS).
While probably not useful, the fact that the "Free Space" hole is after sda9 but before sda10 lines up with the fact that I had to move sda12 and 13 (a FAT32 partition as well as a JFS partition, the one I mount at /storage) down two notches in order for my system to boot up without complaint.
TestDisk is only listing what I've already got fixed and in working order at this point. In other words, it isn't seeing the other partition. Incidentally, PhotoRec, a program analogous to TestDisk, probably wouldn't be useful here since I doubt that partition contains images.

You really got yourself into a big mess ....
As for the partitions magically changing places .... have you recently used gparted (or parted which I believe is the program that actually does the changes) to resize or move any partitions? If you have that's the reason why the partition table is so messed up.
If testdisk can't fix that I have no idea of what can ... once I had a similar problem and testdisk saved the day but I had only ntfs/ext3/swap/extended primary partitions and logical ext3/ntfs partitions.

Successful install within extended partition?

Thanks to my hobby of installing OSes on my computer, I've decided to give Solaris 8 a go on my Dell (mistake #1?) i810-based (mistake #2?) workstation. I am already running Win98SE, Win2KPro, Linux, and BeOS. I have one small primary partition with the rest of the 13GB drive inside an extended DOS partition (mistake #3)?
I have dedicated some space (roughly 1.3GB, mistake #4?) for Solaris within the first 8GB of the drive in hopes that it will play nicely with the other children. This space is inside the extended partition. I understand that about 10MB of this space will go to a Solaris boot partition (oxbe) while the rest goes to Solaris (0x82, looks like Linux swap).
Tyring the install thus far, the installer sees the primary partition and the extended. However, I can't get inside of the extended partition.
Throwing aside the Dell and i810 arguments, is there any hope that I will ever be able to install Solaris 8 6/00 on this drive? Any tips and/or tricks to share?
Thanks in advance.

hi JP
I am using a dell dimension 4100 machine. I already have win200,win98 in the primary drive(10GB) using using 'System Commander' as boot manager to select the OS( to boot into).
I installed slave disk(30GB-IBM)and have been trying with all the possibilities to get the solaris(version-6/00)installed on the slave disk. I used "Solaris 8 Software 1/2" CD. I was not able to get solaris installed on second(slave) disk evenwitth the single user mode.
Looking for ur help badly if u have got any result.

Win7 Crashed: Data recovery from extended partition

Hi,
My DM4 2180US recently crashed and wont boot to Win 7 (not in normal or safe mode), also it is asking for the Recovery Disk to repair. So before I try in recovery Disk I would like to recover the my personal Datas HDD. I tried booting Ubuntu Live (from USB) to access the hard disk, But I could access only the primary partitions (initially came with laptop) bu the extended partition which I created by shringing the primary partion (C Drive). How to access the extended partions of Win 7 in Ubuntu ? basically I want to back up my datas (Docs, Photos, Videos) from the HDD before trying the recovery.
Best Regards,
Karthikeyan D

Hello md_karthi,
I understand you want to back up your data before running a reset on the system.
Because you’re not able to access the operating system that does limit your options:
1st- Turn the PC on and start tapping F11 immediately, if you see windows loading files go across the bottom the screen you can stop tapping. Once the progression bar has loaded it should load you to a recovery manager, now because you have made some changes to partition that lowers the chances of this working. But if you are able to access the recovery manager, if you look in the right column there should be an option that will allow you to back up your data.
2nd- If the first step fails, you can remove the hard driver and attempt to hook it up to another pc and it might read the hard drive as an external and you can try pulling the data that way.
3rd- Last option would be to take the PC somewhere locally and have them attempt to back up your data. Of course majority of these stores do charge some sort of fee for their service.
Let me know if any of these options helps you out. If you have any other questions don’t hesitate to ask.
Thank you.

Can I put the HP recovery (D:) partition in an extended partition?

I recently had to replace my HDD and HP sent a recovery disk set with my OEM replacement HDD which I used to returm my laptop to "factory original" condition. My problem is that it created 4 primary partitions on the HDD, and now I'm looking for a way to non-distructivly increase the number of partitions on the HDD so I can dual boot Windows 7 64-bit and one or more distros of linux. My computer is a Pavilion dv7-3165dx Entertainment Notebook. I would like to preserve all 4 of the partitions that the recovery disks installed. I had an extended partition with logical drives in it on the drive that failed, and while I don't recall the exact configuration of the partitions I'm sure that I didn't delete any of the factory original partitions to make room for the extended partition, I only had to resize the (C: ) partition to make space for my additional partitions.
So, can the HP recovery (D: ) partition be placed inside an extended partition and still function as intended?
I asked the same question about the (C: ) partition on the Microsoft support forums, and ended up with opposing answers, 1 from a "Support Engineer" saying no, and another ftom a Microsoft tech page showing a diagram of partitions in a configuration that would imply that the answer is yes. Since it's a diagram and not a screenshot I can't decide if I want to risk the attempt on it. To tell the truth I would rather have the (C: ) in the extended partition, but i'm ready to do the job by converting the recovery (D: ) partition if the functionality will still be there.
The configuration of the partitions that the recovery disks created is as follows:
As you can see there is plenty of empty space in the (C: ) partition that I can use for my other plans.
BTW, I'm posting this question here because I couldn't find a partitioning section of these forums, and it is about the recovery partition, If there is a more appropriate section maybe a mod will move it, and inform me of where it is.
IF what I post solves your problem please click the "Problem solved" button on my post.
Oh, and if I have helped you, clicking the 'Kudos' star on my post would not hurt my feelings ether.

Those are the standard partitions. All systems should have the system partition as this is necessary for Windows to boot. The large partition is of course the main partition.
In my experiencing, modifying the recovery partition has not had a happy ending. Others may have a different experience, but I have seen the recovery partition fail to function properly after it is modified.
Furthermore, you can run into issues down the road if a dive has more than 4 partitions. Windows, by default, will convert a drive to dynamic if it has more than four partitions. The recovery, either from the HDD or from the disks, is designed for a basic disk and will not recover a dynamic drive. If a fifth partition is added, instead of removing one to make room for one more, then there will be issues with the recovery down the road. There are ways around it, but I recommend avoiding that scenario if possible.
As long as you have the recovery disks, which sound like you do, I would recommend removing the recovery partition so that there will be room for a partition of your choice. The same can be said for HP_Tools. If you really need the advanced diagnostics, a bootable media containing them can be made by downloading the UEFI support environment from the support and drivers page for your unit. The installer will give you the choice to install to the HDD (make a partition) or to make a USB flash drive that is bootable with them. The HP_Tools partition is small, but the purpose is to keep the number of partitions to four or less. Removing the recovery partition (make sure to keep the recovery disks) and the HP_Tools would give the option to add two partitions and keep it under five to avoid the issue of a dynamic drive. A third party tool can be used to resize the C partition to give you the space you need for the other partitions.

Option to extend partition is grayed out in windows 2008 R2

Option to extend partition is grayed out in windows 2008 R2

Ok, so let's sum-up:
- You want to resize your Windows system partition (say C: )
- you failed resizing using Diskpart
- you failed resizing using a third-party server running Windows 2008 and its disk management tool (diskmgmt.msc)
- you failed resizing using Dell Extpart ...
- You have no credit to buy some EaseUS/Acronis/Partition Magic ... stuff
Then the only reliable (and last) solution you have is using Linux GParted, regardless your Partion is physical or virtual;
- if your partition is physical, good for you, boot on the Gparted CD and that would do the trick... just resize, that's a 2 mn Job.
- if your partition is a vmdk disk (VMWare), so you have to tweak your VM forcing it to boot on the GParted .ISO file (to do so: press the F2 key very quickly, as soon as the VM starts). From there, go to the Boot Option of the VM BIOS and select the CD-ROM
as the primary boot disk.
Reboot your VM, now it will automatically boot on GParted, and there you are : you CAN resize your Volume this way, it does work, the procedure is the same as if you resized a physical partition. When done, select 'Apply' and shut down your VM.
In VMWare, go back to the boot option and remove the Gparted "ISO" file from the boot menu (this will let Windows boot again).
Start your VM... Logon Windows... and now you can see your partition is successfuly resized.
You are happy, great Job!

Extended partition on old MBR HDD makes Windows 7 UEFI boot fail

There seems to be a bug in Windows 7 Pro x64 that prevents it from booting on a GPT partitioned HDD when the same machine also has an MBR partitioned HDD with an extended partition.
I have a UEFI bootable PC with two HDDs:
Disk 0 is GPT partitioned and contains Windows 7 Pro x64 and openSUSE systems.
Disk 1 is MBR partitioned and contains Windows XP Pro x64 systems and bootable ISO images.
Both the disks also have separate partitions for data and for booting.
They are normally booted via rEFInd on disk 0 as follows:
UEFI => rEFInd => Windows 7 or GRUB2.
UEFI => rEFInd => disk 1 MBR => GRUB4DOS.
I had previously installed Windows 7 when it was first released, but abandoned it in favour of XP and openSUSE instead. With the end of support for XP I decided to re-install W7. Before doing so I unplugged disk 1 to ensure that W7 booted completely
independently of XP. After installing W7 I installed SP1 and all the Windows updates. The new W7 system could be booted without problem via rEFInd => \EFI\Microsoft\Boot\bootmgfw.efi
However when I plugged in disk 1 W7 would no longer boot. It displayed the message "Windows is Loading Files" as the bar progressed twice before returning to the rEFInd menu. On selecting W7 again it presented the option to "Launch
Startup Repair", but on doing so it too just displayed "loading files" and returned to the reEFInd menu.
I UEFI booted from the installation DVD and ran Repair. When re-booted W7 presented a menu with choice of new and recovered systems, but both failed as before. Neither could be booted in safe mode. Booting directly from the UEFI firmware menu
into W7, instead of via rEFInd, gave similar results.
Investigations showed that the problem is caused by the extended partition on disk 1. If it is deleted, or just hidden by changing the partition type from 0x0F to 0x00, then W7 boots OK. Plugging in an external USB HDD with logical partitions also
prevents W7 from booting.
This all seemed to be similar to the problem described in KB979374, so I downloaded the hotfix (404153_intl_x64_zip.exe), which is supposed to be applicable to Windows 7 as well as WindowsServer 2008 R2. However when the hotfix was run it displayed "The
update is not applicable to your computer" and logged the following error:
error 2149842967 "" (Command line: ""C:\Windows\system32\wusa.exe" "<pathname>\Windows6.1-KB979374-x64.msu" ")
Is this because the version of files mentioned in KB979374 is older (6.1.7600.20617) than the version of Winload.exe in my system (6.1.7601.17556)?
According to http://www.techienewsnetwork.com/247/22/ SP1 included hotfix 979374, but it doesn't appear in the list of Installed Updates given in my W7 control panel. Should it, are hotfixes included in a service pack listed individually? If
not is there any way to tell whether or not hotfix 979374 has been applied?
How can W7 be booted without having to change the partition type code of extended partitions every time, is there a newer hotfix that will fix the problem in Windows 7 SP1?
Almost all the references I can find to this problem are at least 2 years old, which suggests it might have been fixed. Does anyone else with an up to date Windows 7 SP1 have this problem with extended partitions. An easy test is to plug in an external
HDD with logical partitions and see if W7 will still boot.
I don't want to convert disk 1 to GPT as that would make XP un-bootable. Also GRUB4DOS only supports MBR, and it is very useful for booting ISO images as well as XP.
Cheers.

Hi Wade,
To be sure that openSUSE, XP, or any other software on my PC isn't part of the problem I decided to do a new install of Windows 7 on a blank HDD. As I don't have a spare one I had to backup everything on disk 1 (MBR) and then wipe it, including the MBR,
with zeros (using AOMEI Partition Assistant).
I unplugged the original disk 0 so that the PC had just single completely blank HDD (previously disk 1), UEFI booted the Windows 7 DVD and installed W7 again. Unfortunately at this first attempt W7 partitioned the blank HDD as an MBR disk and booted
in legacy BIOS mode, even though I had booted the DVD in UEFI mode. So I deleted all the partitions it had just created and converted the disk to a GPT one.
The next time I installed W7 it was a UEFI one, with an EFI system partition. After installing SP1 and re-booting it a few times to make sure it was working OK I plugged in the external HDD with an extended partition before re-booting. The result
was exactly the same as reported above for the main GPT disk: it briefly flashed "Starting Windows" then displayed "Loading files" for a few seconds as the bars progressed; when Startup Repair was launched it failed as well.
After removing the HDD I booted the new W7 and added some missing drivers and installed all the Windows Updates, including the optional ones. Many hours later the result was a new up to date installation of Windows that worked perfectly (no errors in
any log files), with no other software on the PC. However as soon as the external HDD was plugged in it failed to boot, as described previously.
I then ran Bootrec from the DVD, trying all the commands, but the results were exactly the same: everything worked successfully but no Windows installations were found, and it didn't fix the problem.
The documentation on how to use Bootrec describes how to backup the BCD store that is on the C: drive (e.g. "ren c:\boot\bcd bcd.old"). However the BCD store for UEFI based systems is in the EFI system partition, NOT on the C: drive. This suggest
that Bootrec does not apply to UEFI based systems.
Are you sure that the MBR is used when booting in UEFI mode? From what I have read in several places (not MS pages) the protective MBR on the GPT isn't used, but instead the UEFI firmware runs \EFI\Microsoft\Boot\bootmgfw.efi which looks in the BCD store
in the EFI partition. Can you point me to any MS documentation please that explains exactly how UEFI booting works for Window 7, including its use of the MBR.
Do you have a Windows 7 system that can boot from UEFI when an MBR disk with an extended partition is attached. If so how is your installation different from the one I have just set up, i.e. Windows 7 installed on a PC with just
a single empty GPT HDD?
Do you work at Microsoft? If so perhaps you could find out if anybody with a straightforward UEFI booted Windows 7 has problems when an MBR HDD with an extended partition is attached.
Sorry for the delay in responding, but a lot of work was involved.

Can't create extended partition!

Hello,
cfdisk is not allowing me to create an extended partition. I have 3 partitions and need another 3 for Arch (boot, swap, root).
When I go into cfdisk, I see the free space I have, when I press "New", I get Primary or Logical. I first chose Primary, then went into "Type" and pressed 5 to make it Extended.
I get the "Cannot change FS type to extended" error.
I tried again with the Logical option and still the same error.
Help?

Installing arch on extended partition/logical drive

hi there. i am a newbie to linux and about to install arch as my first linux installation.
i am using vaio AR laptop already running xp and would like to keep it and have double boot without reinstalling xp.
have 200gb hdd with recovery primary partition, system primary partition (where xp installed) and extended partition with one logical drive (D: ) of 100gb.
i was considering deleting the logical drive (and the extended partition if necessary), which if i understand correctly should give me 100gb of unallocated space.
i would then like to install arch on the 100gb of unallocated space.
i would like to know if the way i am planning to go about it is possible, and whether i can install arch completely on one extended partition devided into logical drives.
any comments or sugestions would be much appreciated...

I believe that is correct. Grub has to have a reference to the md0 raid for booting.
Please see
http://bbs.archlinux.org/viewtopic.php?id=79306
This solution to the boot problem with md0 should be helpful for your case since grub must be modified to accomodate the raid.
I am not sure the data in your raid0 is appropo for your use in booting archlinux, however. If I understand correctly, it is windows related data and not applicable to linux.
If your raid0 is partitioned, it would be possible to establish a boot for each system using grub partition references differing for linux and windows systems.
Thus, you would have grub entries complete for linux and another set complete for windows.
I think AFAICT windows has to be first in the usual dual booting but am not an expert on that, not having used dual boot. It may be somewhat different when using raid for booting dual systems.
I suggest you read the wiki on dual boots.
Perhaps you will get advice from others on the subject also.
EDIT: Your asumption that all OS'es will recognize the raid0 devices as a single drive does not apply to archlinux which does not autodetect raid arrays but must have initramfs populated with the raid data established by mdadm and initiated into initramfs by mkinitcpio. Then during boot sequences , the array is assembled and enabled as a single drive,i.e., md0. The boot sequence assembles all drives having identical UUID's in the raid array.

Canot erase my macbook air ssd..always create a extended partition with about 5G used space

I cant erase my air ssd, always create about 5G used extended partition..

Try booting the fallback kernel, there is a problem with the AHCI driver concerning new Macbooks. When you've booted, add ata_generic to the modules in /etc/mkinitcpio.conf and rebuild the initrd with mkinitcpio -p kernel26.

[SOLVED]Backing Up Extended Partitions

I need to restore my Win 7 install which will reset my drive to the state Windows was in when I created the restore image - pre Arch.
All of my Linux partitions (/home /swap /boot FAT32 data) are in an extended partition, /dev/sda4.
I can use dd to backup each individual partition to an external drive, but I think that is error prone. dd will not copy /dev/sda4 and the partitions it encompasses (sda5-sda8).
I stumbled upon
sfdisk -d /dev/sda4 > backup-sda.sfdisk
but I believe it just backs up the partition table and not the actual partitions and data.
Any insights or utilites that might be easier then dd'ing each individual partition and restoring that way? I'm worried about preserving swap, etc.

Sounds like a good job for fsarchiver! It will save whatever partitions you tell it to, then restore them to another partition when you're ready. It'll put all 4 partitions in the same file if you want.
