Now I want to install it in partition boot-sector because I need the original MBR not overwrote.
I tried with Linux RecueCD using following commands
CODE
grub
root (hd0,0)
setup (hd0,0)
root (hd0,0)
setup (hd0,0)
and it seems to install itself [however "fat_stage1_5" failed occurs, although that file is in "boot/grub" root folder (with "stage1" and "stage2" files too)]: "gldr" is in the root directory and "menu.lst" (existing in "boot\grub") content is as following (really the same of previous working install)
CODE
title Windows XP
rootnoverify (hd0,0)
chainloader (hd0,0)+1
boot
rootnoverify (hd0,0)
chainloader (hd0,0)+1
boot
Then GRUB prompt appears at boot (like the working previous install in MBR), but system does not do... and the prompt reappears without boot.
Any suggestion will be greatly appreciated.
EDIT (Addenda)
I hope this is the right forum's place for thread.
Furthermore I wonder if is needed a specific file system in order to GRUB working (I tried FAT, FAT32 with the same results... and NTFS is not recognized) and if it's needed a minimum partition size.
