You can't just +have installed grub on your MBR at some point in the past, then install +grub2 (or anything else, for that matter) on the MBR again, and expect +your original partitions to boot ? + +In MGA install terms, and specific to the case of grub2 on the MBR +trying to boot grub on a PBR, you have to boot the grub partition (or do +the boot-elsewhere/chroot thing), modify the /boot/grub/install.sh to +not target the MBR (stage2=(hd0)) but indicate the PBR (stage2=(hd0,x)) +and rerun install.sh to install grub on the PBR. + +In terms of the install paradigm, you have to choose to install the +bootloader to the PBR (sdaX) rather than the MBR (sda). Otherwise, when +the MBR bootloader, whether grub2 or grub, boots and chains to the PBR +of the desired partition, there won't be anything there in the PBR to boot. + +If you need clarification on this, ask, and give specifics. The +objective of chainloading is to have each PBR (partition) behave as if +it is its own MBR. If you try to point grub2 menu entries to native +partiton grub files, or vice versa, you are just asking for trouble. +The clean way to do it is to use chainloading to link the MBR (whatever +it is) to the PBR (whatever it is), and let the PBR do the bootloading +for its own partition according to its own needs. + +If you do it this way, you can install whatever you want as a bootloader +on the MBR, and each partition can have whatever BIOS-compliant +bootloader it wants, including grub, grub2, lilo, OS/2, DOS, or Wndows. +</PRE> + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="021885.html">[Mageia-dev] Grub2 vs. Grub Legacy in M3 +</A></li> + <LI>Next message: <A HREF="022146.html">[Mageia-dev] Grub2 vs. Grub Legacy in M3 +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#21895">[ date ]</a> + <a href="thread.html#21895">[ thread ]</a> + <a href="subject.html#21895">[ subject ]</a> + <a href="author.html#21895">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> |
