My computer has a partition for linux fedora (the default OS) and also XP. When I boot up, I get the following: Grub loading stage 1.5 Grub loading, please wait..... error 21 When I hit enter, I get a blank screen with a blinking cursor. Now, I hit Ctrl-Alt-Del, and suddenly the Grub bootloader goes thru with no trouble. What is error 21, or at least where can I find the error codes for information, and how do I fix the problem; preferably without re-installing?

Now ive had my fair share of grub problems in the past and most of them just consisted of me booting from a live disk, then >grub >root (hd0,0) then >setup hd0 and that was it. now for some reason everything ive tried resulted in "Error 21: Selected disk does not exist". Ive tried root (hd0-4,0-5) and same error everytime. any suggestions? is it possible it doesnt like that my ubuntu is on an extended partition?

Memory related issue - damaged memory sticks, damaged memory blocks, and space allocation issue can cause this error as well. If im not wrong i think it all started when i got my new mo
