 |
|
Hi, there! I'm actually a Sabayon user, but I think you guys are probably more knowledgeable. I set up a fake bios raid...
It works except for XP won't boot...I used to use just Linux, but I need Windows for college. Grub displays with menu options and Sabayon boots and thats wonderful!
Here is my hard drive layout:
First partition = /boot (mount point) contains boot files and Grub
Second partition = NTFS (This partition has boot flag) Here is my windows XP install
Third partition= Linux Swap
Fourth Partition = / mounted @ root
Here is how its defined in cfdisk:
| Code: |
Disk Drive: /dev/mapper/isw_bcehhdfdci_TOWER_RAID1
Size: 320080969728 bytes, 320.0 GB
Heads: 255 Sectors per Track: 63 Cylinders: 38914
Name Flags Part Type FS Type [Label] Size (MB)
------------------------------------------------------------------------------
isw_bcehhdfdci_TOWER_RAIPrimary Linux ext2 690.93
isw_bcehhdfdBootOWER_RAIPrimary NTFS [^R] 160039.28
isw_bcehhdfdci_TOWER_RAILogical Linux swap / Solaris 3142.06
isw_bcehhdfdci_TOWER_RAILogical Linux ext3 156206.30
|
Here is what the /dev/mapper looks like:
| Code: |
control isw_bcehhdfdci_TOWER_RAID16
isw_bcehhdfdci_TOWER_RAID1 isw_bcehhdfdci_TOWER_RAID1p1
isw_bcehhdfdci_TOWER_RAID11 isw_bcehhdfdci_TOWER_RAID1p2
isw_bcehhdfdci_TOWER_RAID12 isw_bcehhdfdci_TOWER_RAID1p5
isw_bcehhdfdci_TOWER_RAID15 isw_bcehhdfdci_TOWER_RAID1p6
|
RAID1=Just Name of Raid
RAID11=Windows
RAID12=boot
etc...
Here is how grub shows it:
| Code: |
root (hd0,0)
Filesystem type unknown, partition type 0x7
So, I know the above is a NTFS
root (hd0,1)
Filesystem type is ext2fs, partition type 0x83
Obviously, thats my partition to the Sabayon install
|
Now, are you ready for this? Drum roll please....My grub.conf file
| Code: |
# grub.conf generated by the Sabayon Linux Installer
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,1)
# kernel /kernel-genkernel real_root=/dev/mapper/isw_bcehhdfdci_TOWER_RAID16
# initrd /initramfs-genkernel
#boot=mapper/isw_bcehhdfdci_TOWER_RAID
default=0
timeout=6
splashimage=(hd0,1)/grub/splash.xpm.gz

Thanks for the reply and I believe you are correct. However, I got this error: error 13 invalid or unsupported executable format. Does this mean my windows install is smoked? If so, can I just set the boot flag to hidden on the first partition and then reformat and install my XP with partition magic? Can I use gParted on it?Would I just reinstall grub when I am done, or would I not need to?
This is my first time dealing with fake raid--I believe I hit every pit trap along the way  At least I learned a lot though...
Thanks |

I've never gotten map to work right. Putting Windows on anything other than the initial partition has, in my experience, always been nothing but an excercise in frustration.
I'd recommend giving Windows what it wants. Reinstall time. =x

hmmm...puzzler. I think I forgot to set the first partitions flag to hidden. I'll try that.
A guy suggested that I try this...
ls -Fla /mnt/windows
It seems good...
| Code: |
# ls -Fla /mnt/windows
total 8
drwxr-xr-x 2 root root 4096 2008-08-03 07:10 ./
drwxr-xr-x 6 root root 4096 2008-08-03 07:10 ../

Also, its a fake raid and thats why /boot has to be first...
It won't let me change the flag to hidden...I'm running out of ideas. |

If you want to run windows XP from the second partition modify the windows boot.ini file. My file for running Windows XP from the second partition is | Code: | [boot loader]
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows XP Media Center Edition" /noexecute=optin /fastdetect
|
The only thing that needs to be changed in the file is the partition number. |
