detect stage1.5 in GRUB
 

My program must detect - GRUB has installed stage1.5 or not.
(GRUB can install with:
stage1-stage1.5-stage2
or:
stage1-stage2)
how can detect it?

ummm what error are you getting please.....or what program are you trying to use to monitor a boot up? ....its not yet clear to me what you want thanks

My program must change partition (for example - resize) and correct adress in GRUB pointed to stage1.5 or stage2 (otherwise GRUB will not work).
Therefore i need know: stage1.5 installed or not.

if you resize any parition then you need to be careful with any MS system.....go into MS first and defrag and make sure no programs are at the end.

2) linux systems are generally ok to resize without such concerns.

3) then use a live cd to re-install grub to mbr....to point to the new location of its booting files as per tut its

(using knoppix or kanotix)
open a terminal
su
grub
root (hdX,y) .....where is /boot partition in grub speak
root (hd0)......assuming your bios detects hd0 b4 any other drive

accually,

oops on dup of root my apols
