hi: Excuse me ! Can you help me with my grub error? After I upgrade grub to grub2 , my linux can not boot up. When load from hd1. screen prints this: symbol not found :"grub-putchar" entering rescu mode ... grub rescue > I searched google for solutions.It seems that I shoude repair my grub files. But in this mode ,I only can use "ls" and "set" command . can not use "insmode" command ? so I feel difficulty to fix it . Is there any method to activate all the commands? Can I use a bootable floppy image to boot my linux ? I have download a bootgrub image file , I can use this file directly as a floppy device .and can boot from it , only to see a boot list on the screen . I should select which item to boot ? or something other additional to do? thanks!
