Grub can't output to display

Question

ok, so I  dual boot debian and arch and today I dist-upgraded to wheezy only to find arch gone from the boot menu. I workaround this by chrooting into arch and install grub there, and now and typing from arch. however, on boot after the bios flashes I get this message: can not output to this display. now, hitting enter boot arch, but a. I am completly blind in the grub menu and b. I have no of telling if debian is in the boot menu other then trail and error, which I havn't tried yet because thats really a different issue. any ideas on what might be causing the problem? which arch boots everything is fine from there, this is just a grub issue

Answer 1

even with arch mounted and os-prober installed debian fails to see arch (i've filed a bug report with debian) arch os-prober sees debian, but like I said, no video so I can't really tell what the menu looks like until I found that problem. anyway, heres /grub/default. I may try updating grubs menu again and see what happens
