Help! My Linux won't boot.
;Loading Linux.......... Uncompressing the kernel. (stop) :
;GRUB <blinking cursor>: GRUB is unable to load it's first stage loader, use a rescue disk to start the machine. Re-install grub.
;I get the grub command prompt instead of my menu but if I type in "configfile /grub/grub.conf" the menu loads: This may occur with a Mirrored SoftwareRaid setup. Reconfigure your grub.conf file and remove any reference to a root (*) device.
install --stage2=/boot/grub/stage2 (hd0,0)/grub/stage1 (hd0) (hd0,0)/grub/stage2 p /grub/grub.conf install --stage2=/boot/grub/stage2 (hd1,0)/grub/stage1 (hd1) (hd1,0)/grub/stage2 p /grub/grub.conf quit
NB: This assumes a seperate /boot partition ;I'm having the same problem, but I'm not using RAID or anything...: From all the research I've done, it seems like problems of this sort are always caused by grub.conf mistakes. Mine seemed to be OK though, but I was still seeing problems. I noticed that when I ran
setup (hd0)
at the grub prompt, it mentioned a file called menu.lst . I renamed grub.conf to menu.lst, and things are now working! Apparently there may be multiple default filename possibilities for the GRUB menu file.
Don't rename grub.conf - make a symbolic link from grub.conf->menu.lst (man ln)
Various VIA chipset AMD Athlon/Duron motherboards (eg KT400, KM266) running kernel 2.4 (e.g. kernel 2.4.21) hang after printing this message. For example, Athlon XP2000+ on an AD77 motherboard (KT400), Athlon XP1800+/XP2400+ on a PC Chips M825L (KM266)). It is caused by APIC support in the kernel (not to be confused with "ACPI"). Booting with the "noapic" kernel flag doesn't fix it (although it can make the machine go into an infinite loop printing an error about apic on cpu 0). However, booting with "nolapic" kernel flag does in many cases work. Recompiling the kernel without APIC support resolves this. Note that the same motherboards will need the "nolapic" kernel flag to boot Knoppix - otherwise the screen just turns black and the pc hangs.

I've added some other grub-specific tips under GrubNotes, where do people think they should go? Merged into here? Have the Grub specific points merged back into GrubNotes? --DanielLawson
GrubNotes belong in GrubNotes, I think. There should just be a pointer here, like "GRUB might be unable to find its config file. See GrubNotes.". --AristotlePagaltzis
