 Posted: Sun Oct 08, 2006 11:41 am Post subject: Windows fake RAID0 migrate [SOLVED] |
 |
|
Hello all,
I have finally gotten over to purchasing a new HDD (320GB  ). My current state is the following: | Code: |
2x15GB fake (BIOS/chipset) RAID0 - Windows drive
1x160GB - 50GB NTFS blank, 110 - Linux use
1x320GB - new disk to be used for file sharing in my home network. |
What I would like to do is: | Code: |
1x160GB - 50GB Winows drive, 110 - Linux use
1x320GB - new disk to be used for file sharing in my home network. |
I tried doing this the obvious way of copying everything from my RAID0 to the 50GB blank partition I setup just for this purpose, edited GRUB... and got a hang (black screen with my GRUB text and a blinking cursor)^^ Here is my /boot/grub/grub.conf (relevant): | Code: | # Windows System
title=Windows XP
rootnoverify (hd0,4)
chainloader +1 |
Before you ask, the NTFS partition on the 160GB HDD is /dev/sda5.
I would really appreciate your help, as having 2 outdated disks in my Case just because of the fear of having forgotten something during my data migration is not good for my ears:-(
Thank you all for any help!

jakubc,
You don't say which drive you are booting from now, or what adjustments you have made to the BIOS boot order.
If you are booting from the new 160Gb drive, you will need to reinstall grub to the MBR, as grubs stage 1 and 1.5 both reside outside of the file system.
With the two 15Gb drives removed, you may find that the BIOS renumbers the drives that are left.
This will also make a mess of the grub image on the MBR, as some changes are made to it at install time.
Remove (disconnect) the two 15Gb drives, boot into Linux using a liveCD, mount your partitions, chroot, and reinstall grub to the MBR.

Hello NeddySeagoon,
thank you for your reply.
I could never quite setup GRUB to work with the RAID0 drives and boot into Windows. What I did was each time I wanted to boot into Windows, I would simply change the boot order in the BIOS (I boot there ~1 a month, so no biggie...). Anyway the 160GB HDD has GRUB installed, and is set as the primary Boot disk (GRUB boots from it into Linux just fine), and has the following partition table: | Code: | Disk /dev/sda: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 2 19929 160071660 f W95 Ext'd (LBA)
/dev/sda5 2 6410 51480261 7 HPFS/NTFS
/dev/sda6 15341 15349 72261 83 Linux
/dev/sda7 15350 15474 1004031 82 Linux swap / Solaris
/dev/sda8 15475 19929 35784756 83 Linux |
I think there may be something with the way I simply coppied the Windows files from RAID0 to the 160GB disk, but as I've not found anything on the Forums I am not sure:-(
Any more help would be greatly appreciated!

jakubc,
Boot as far as the grub splash screen and press 'e' to edit your grub.conf.
Move to the rootnoverify (hd0,4) line. Change it to read
then press tab.
Grub will list the disks it sees. Add the 0, to get to
and press tab again.
Grub will list the partitions on the disk. Does it look like the right disk ?
Also try root, in place of rootnoverify.
None of the changes you make here are written to disk.
When it works, change grub.conf manually.

Hello NeddySeagoon,
tried what you advised. hd0,4 really is pointing to the correct partition as far as GRUB goes, and changing rootnoverify to root got me this: | Code: | rootnoverify (hd0,4)
Filesystem type unknown, partition type 0x7
chainloader +1 |
and a hang, which I got out of by the help of ctrl+alt+del.
Do you think just plain old copying (and by copying I mean the command "Copy" in TotalCommander) the RAID partition over to the 160GB HDD did the trick for Windows (that's my best bet for what went wrong^^)?
Thank you again!

jakubc,
Partition type 0x7 is NTFS - so that is undoubtedly the right partition.
I have a feeling that the Windows system partition needs to be a primary partiton but don't take my workd for that.
Its ben a whle since I had Windows.

Hello NeddySeagoon,
thank you for your help. Thanks to you I have narowed my problem down to either:
1/ problem with the way I coppied to partition
or
2/ maybe the disk data is on a non-primary partition.
Could someone with experience with this help?
Thank you!

Hello all,
an update on my situation...
I have copied the whole RAID0 partition to /dev/sda using partition magic, and made that copy on /dev/sda a primary partition... what it did to my /dec/sda is this: | Code: | Disk /dev/sda: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 3736 19929 130078305 f W95 Ext'd (LBA)
/dev/sda2 2 3735 29993323+ 7 HPFS/NTFS
/dev/sda5 15341 15349 72261 83 Linux
/dev/sda6 15350 15474 1004031 82 Linux swap / Solaris
/dev/sda7 15475 19929 35784756 83 Linux
Partition table entries are not in disk order |
so I had to change my /etc/fstab, and more importantly my /boot/grub/grub.conf to this: | Code: | rootnoverify (hd0,0)
Filesystem type unknown, partition type 0x7
chainloader +1 |
however still no luck (the loading still hangs on a black screen with the text above).
I hope this makes my problem clearer... I am getting desperate

jakubc,
(hd0,0) is your sda1, which is your extended partiton
You probably intended (hd0,1)

Hello NeddySeagoon,
sorry about that, I was in a hurry, and pasted wrongly... my /boot/grub/grub.conf looks like so: | Code: | # Windows System
title=Windows XP
rootnoverify (hd0,1)
chainloader +1 |
... and still no luck:-(
Do you think making the disk windows bootable with Partition Magic, and then seting up GRUB again would help?

jakubc,
I think you are missing a makeactive now as in
| Code: | root (hd2,0)
makeactive
chainloader +1 |
Thats a sample to show where the makeactive goes. Windows likes to be on a partition marked as bootable but grub won't care.
Look in the /boot/grub/grub.conf.example too.
There is no need to reinstall grub - it reads its grub.conf on every boot, unlike lilo, which only reads it when /sbin/lilo is run.

Hello NeddySeagoon,
comming back with my status report...
I found a post on the forums which got me thinking (hapens to me sometimes ). Anyway I went back, and compared the partition tables of the Raid0 disk, and my 160GB... and I noticed, that my 160GB had a bit of unused space at the start of the disk. I used the handy partition magic again, and got this (don't mind the second windows partition, it's the backup of my backup^^): | Code: | Disk /dev/sda: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 3735 19929 130086337+ f W95 Ext'd (LBA)
/dev/sda2 * 1 3734 29993323+ 7 HPFS/NTFS
/dev/sda5 3735 7468 29993323+ 7 HPFS/NTFS
/dev/sda6 15341 15349 72261 83 Linux
/dev/sda7 15350 15474 1004031 82 Linux swap / Solaris
/dev/sda8 15475 19929 35784756 83 Linux
Partition table entries are not in disk order |
as you can see the disk now starts at 1 inseat od 2, which is what probably made the difference (btw. I think this could have been fixed with the chainloader+something command in grub, but not sure), as I can now boot into windows no problem (/dev/sda1 is still set as primary).
Thank you for your great support! I will now try to enlarge my /dev/sda8 so that it uses the rest of the unalocated space, so I might be posting in a second:-)))
