Problems installing dual boot system

ernesto_lelo · 07-02-2004, 06:34 PM

Right now I'm running at my P4 wins 2000 and red hat 9. My boot system is working perfectly with grub. Unfortunately I'm force to format my Windows partition. I know that everytme you format and re-install windows he boot partition will ony but windows. I also know that using lilo there is a way to re-buiild the boot partition (creating a floppy disk and after installing windows running the boot disk), but I don't know how to do it using Grub
Any idea?

i use lilo myself and there you just have to rerun lilo to get the lilo-mbr in place again. i assume that reruning grub will do the same. boot with your linux cd, add root=/dev/yourrootpartition at the cdrom-prompt, and run grub (or how the grub-installer is called).

Read the 'grub' man page. There is a section called, creating a grub boot-floppy. After creating the boot floppy, test that is works. Then when the windows re-install wipes out the boot loader, you can still boot up into linux to re-install grub.
