greetings ,
i know the title is a very bad one, but i'm in real danger so help me, pleasee!!
i was toying around at the login prompt a little while ago in one of the machines at our lab, inputting different combinations for the root password (just toying!) and suddenly one of them clicked and made me the root!
this machine is a dual-boot one -windoze and linux;
so, out of curiousity , i went to the /etc/grub.conf file and pored over its contents;
ACCIDENTALLY, I UNCOMMENTED THE chainloader +1 and rootnoverify OPTIONS!!
NOW, WHENEVER I REBOOT THE PC, ONLY WINDOWS BOOTS!!
NO LINUX!!
(the boot menu displays the linux option but pressing it only boots windoze)
IS THERE A WAY TO MAKE IT BOOT LINUX AGAIN, CHANGING OPTIONS ON WINDOWS COMMAND LINE??
please save me; if sysadmn finds me, i'm a goner!!
please reply quickly!
regards,
aru

u can reinstall ur boot loader in rescue mode.

insert first boot cd.
enter in to rescue mode.
chroot /mnt/sysimage
grub-install <hdd> EX: /dev/hda /dev/hdb.
exit.

well u can boot from a rescue CD or any live CD

mount the root partition and again make chamges to it

and if u can post ur grub.conf here we can suggest u some help

A dual boot box in a lab with extremely weak security. The sysadmin is probably your best friend in this fiasco because you both should be gone. Tell him or her what you did and get the problem fixed fast.
