One of my operating systems (a version of Debian Squeeze) is now refusing to boot. It just shows a black screen with the 2 words GRUB GRUB in the top left hand corner. I wonder if anyone has seen this sort of behaviour before?
More background: I have multiple operating systems on my PC which can be selected by means of a boot manager (BootitNG), including 3 versions of Debian Squeeze, Linux Mint and Windows 7. The boot manager resides in the master boot record and when I select an OS to run it sets up the master boot record for the selected OS, then passes control to Grub located in the root partition. This has been working without problem for some months (years in the case of Debian Lenny, with the original Grub). At first I suspected a hardware fault, but the other Debian works ok. In fact all the other OS's do, with one exception - Kubuntu. In fact I had just installed Kubuntu 64 bit so I suspect its possible this had something to do with the problem. Kubuntu ran ok on its first bootup but now on trying to boot into it for a second time it boots but doesn't complete booting. (I only installed it out of curiosity and I have now deleted it from the system) However the problem is strange. My boot manager is also able to take an image of a partition and I restored the image of the failed Debian Squeeze system from a known good copy, but to no avail. I use a common swap partition for all my Linuxes, and I have 3 other partitions (2 drives) for data which all OS's have access to. Each Linux has its own additional tmp partition. I wondered about some issue with the common swap partition but my other 3 Linuxes (two Debian one Mint) are using it with no problem. I wondered whether Kubuntu has somehow altered some BIOS setting but I can't see any changes - also the other Debian isn't affected. Or maybe it has subtly changed something which GRUB uses to identify the UUIDs. Any ideas would be very welcome. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
