after day long googling, i edit grub2 loader as follows;

add the following line in 40_custom file in order to add winxp boot entry;

-----------------------

menuentry "Windows xp (loader) (on /dev/sda1)" {
insmod ntfs
set root=(hd0,1)
search --no-floppy --fs-uuid --set 6270DE7670DE5101
drivemap -s (hd0) %{root}
chainloader +1
}

---------------------------
while updating grub2, grub.cfg found the xp partition successfully.
but after rebooting and loading xp, it left blank and returned grub boot loader menu instantly..

i cant boot xp and i am totally out of world

anybody have an idea about what happend..
pl i need urgent help.

[khmadhu]

instead of set root=(hd0,1) add rootnoverify (hd0,1) or rootnoverify (hd0,0)
and try.

otherwise best option is reinstall grub boot loader

1)boot from ubuntu CD/DVD
2)go to recovery console,u will get a console
3)type chroot /mnt/sysimage
3)then type grub-install /dev/sda

it will automatically detect all OS and reinstall's boot loader.

^ Just boot through the Ubuntu 9.10 Live CD and open terminal. Then do what khmadhu has posted.

[Sathish]

I already told that boot menu does not contain anything like recovery console or terminal or command prompt then how can i get console/terminal window in boot menu?

i am using ubuntu 9.10 Live CD shipped from canonical.

And I've written that just boot through the live CD and "get to the desktop" just the way you run a live CD "normally".

[Sathish]

while entering chroot /mnt/sysimage..
returned with the following error..
"cannot change root directory to /mnt/sysimage no such file or directory "

i have execute this command as root

hey, my problem is not recovering grub2 boot loader.. i already done it and now ubuntu 10.4 successfully boot..
but im not able to boot winxp which is resided at sda1. that is the problem.
i have done everything in the wiki page .but still i struck. so that i came to this forum.

[khmadhu]

but im not able to boot winxp which is resided at sda6.

i think u should give
rootnoverify (hd0,6) if u r windows is in sda6.!

I tried.. but no use..

i would like to say that Xp was booting perfectly without any problem from grub loader while i working last week..

but one thing i missed to inform.. Sorry guys.

Actually i have 3 OS xp. win7 rc and ubutnu 9.10 as follows
xp and ubuntu are in first hard disk (xp is sda1 and ubuntu is sda5)
win7 was on second hard disk (i.e. sdb3)

Ubutnu 9.10
Ubuntu 9.10 recovry
Mem test
windows 7

xp was booting through win7 boot loader.

even i removed win7 rc from hard disk and delete the partition, xp still loaded from win7 boot loader.
after i upgarding ubuntu 9.10 to 10.4 beta, the above problem has arrived and i am unable to boot xp through win7 boot loader.

can u Understand my problem right way .?

[khmadhu]

do one thing..

boot from xp cd. dont install ,choose recovery console,and u will get a dos prompt.
there u type

fdisk /mbr

this will try to rewrite the bootloader.. restart and see the difference.

[Sathish]

i have done Too. it creates another problem.

as i have xp professional OEM disk (original), setup cannot proceed and ended with pci.sys error (bsod).
after searching google, i have found that unless sp2 slipstreamed installaton disk used, setup will not succeed in new motherboards and ending with various blue screen of death error.

i dont have standby system to slipstream sp3 to the oem edition..
is there any way to do slipstream in ubuntu.?
or is there any third party software to repair the xp..?

[khmadhu]

well in that case u could try "hirens boot cd". google around to download.

i extensively use this tool for all this type of mess . i am sure u gonna love it.
